Abstract
Epithelioid hemangioendothelioma (EHE) is a remarkably rare tumor arising from endothelial cells that is classified as a vascular tumor in the WHO classification. The tumor is predominantly characterized by the presence of fusion genes, such as WWTR1-CAMTA1 or YAP1-TFE3, with a minority of cases exhibiting other rare fusion genes. EHE exhibits a broad age of onset, typically presenting at ~50 years, but it is not uncommon in pediatric populations. It manifests in a variety of organs, including the liver, lung, soft tissue and bone. Initial multiple-organ involvement is also observed. The tumor's biological behavior and prognosis vary substantially based on the primary site of manifestation. From a therapeutic perspective, initial active surveillance might be considered in selected cases, although surgical intervention remains the mainstay of treatment, especially for localized single-organ involvement. Chemotherapy is administered to patients with progressive unresectable tumors. Recent advances in the biological analysis of EHE fusion genes have elucidated their diverse functions. Additionally, next-generation sequencing has facilitated the identification of other mutations beyond the fusion genes. These continuous efforts to understand the biology of the fusion genes themselves and/or the dysregulated signaling by fusion genes are expected to lead to the development of novel therapeutic strategies for EHE. This article aims to provide a comprehensive review of EHE, encompassing its historical context, clinical manifestations, molecular biology and the current state of treatment.

Abstract
PURPOSE Hepatic epithelioid hemangioendothelioma (HEHE) is a rare tumor with currently no established standard of care. This international multicenter retrospective study assesses the use of percutaneous irreversible electroporation (IRE) as an ablative tool to treat HEHE and provides a clinical overview of the current management and role of IRE in HEHE treatment. MATERIAL AND METHODS Between 2017 and 2023, 14 patients with 47 HEHE tumors were treated with percutaneous IRE using CT-scan guidance in 23 procedures. Baseline patient and tumor characteristics were evaluated. Primary outcome measures included safety and effectiveness, analyzed using Common Terminology Criteria for Adverse Events (CTCAE) and treatment response by mRECIST criteria. Secondary outcome measures included technical success, post-treatment tumor sizes and length of hospital stay. Technical success was defined as complete ablation with an adequate ablative margin (intentional tumor free ablation margin > 5 mm). RESULTS IRE treatment resulted in technical success in all tumors. Following a median follow-up of 15 months, 30 tumors demonstrated a complete response according to mRECIST criteria. The average tumor size pre-treatment was 25.8 mm, accompanied by an average reduction in tumor size by 7.5 mm. In 38 out of 47 tumors, there was no evidence of local recurrence. In nine tumors, residual tumor was present. There were no cases of progressive disease. Median length of hospital stay was one day. Only one grade 3 CTCAE event occurred, a pneumothorax requiring chest tube placement. CONCLUSION The current study provides evidence that IRE is a safe and efficacious minimally invasive treatment option for HEHE.

Abstract
Epithelioid hemangioendothelioma is a very rare vascular neoplasm, which is often multifocal or metastatic at diagnosis. Most frequently arises in the liver, followed by the lung and bones. The authors present a case of a liver transplant recipient who developed a pattern of hepatic cholestasis associated with the appearance of a proliferative hepatic lesion with infiltrative growth. Histological examination and immunohistochemical study were compatible with the diagnosis of epithelioid hemangioendothelioma. Pulmonary micronodules were detected and lung metastases were hypothesized. Therefore, bronchoscopy was performed, which turned out to be normal, and cytology was negative for neoplastic cells. After a multidisciplinary discussion, liver re-transplantation was decided. After 8 years of follow-up, the patient is clinically stable, with no graft dysfunction, no neoplastic recurrence, and dimensional stability of the pulmonary micronodules. Patients with organ transplant have higher risk of developing carcinoma compared to the general population. The development of cancer is a multifactorial process and little is known about the etiology of epithelioid hemangioendothelioma. No standard treatment strategy has been defined yet, and the natural course of the disease is heterogenous and the individual prognosis unpredictable. Complete surgical resection is offered to patients with unifocal disease, and those with unresectable disease should be evaluated for orthotopic liver transplantation.

Abstract
Background: Exposure to zoonotic diseases is a significant occupational risk in veterinary medicine. In this study, we characterized personal protective equipment use, injury frequency, and Bartonella seroreactivity in Washington State veterinary workers. Methods: Using a risk matrix developed to reflect occupational risk factors for exposure to Bartonella and multiple logistic regression, we explored determinants of risk for Bartonella seroreactivity. Results: Depending on the titer cutoff used, Bartonella seroreactivity was between 24.0% and 55.2%. No significant predictors of seroreactivity were found, although the relationship between high-risk status and increased seroreactivity for some Bartonella species approached significance. Serology for other zoonotic and vector borne pathogens did not identify consistent cross reactivity with Bartonella antibodies. Conclusion: The predictive power of the model was likely limited by the small sample size and high level of exposure to risk factors for most participants. Given the high proportion of veterinarians seroreactive to one or more of the three Bartonella spp. known to infect dogs and cats in the United States, as well as seroreactivity to other zoonoses, and the unclear relationship between occupational risk factors, seroreactivity, and disease expression, more research is needed in this area.

Abstract
Bacteria of the genus Bartonella, a member of the Alphaproteobacteria, are fastidious, Gram-negative, aerobic bacilli that comprise numerous species, subspecies, and genotypes. Bartonella henselae, with a worldwide distribution, infects cats, dogs, horses, humans, and other mammals. Diagnostically, direct detection of Bartonella henselae in patient blood specimens by culture or molecular methods is required to confirm infection with this bacterium. Enrichment blood culture combined with quantitative PCR (qPCR) or ddPCR enhances the sensitivity of direct detection. The addition of sheep blood to liquid culture media increased the Bartonella henselae DNA concentration compared to controls, additionally improving PCR direct detection sensitivity. IMPORTANCE This study aims to improve diagnostic detection of Bartonella henselae. Patient samples are combined with enriched bacterial cultures aimed at growing Bartonella henselae for the best possible chance at detection. However, current Bartonella growth methods could be improved. The DNA extraction method used by most laboratories should also be optimized. Sheep blood was added to increase the growth of Bartonella henselae and multiple DNA extraction methods were to be compared to each other.

Abstract
RATIONALE Epithelioid hemangioendothelioma (EHE) is a rare, low to moderate-grade malignancy, even less in pulmonary endovascular neoplasm. Patients with pulmonary EHE have no optimal treatment, resulting in poor prognoses. PATIENT CONCERNS We reported a 42-year-old man with multiple mild metabolic uptakes in pulmonary endovascular filling defect with a maximum standardized uptake value of 4.5 by 18-fluorodeoxyglucose/fibroblast associated protein inhibitor-positron emission tomography/ computed tomography. Anticoagulant treatment was not effective with the diagnosis of acute pulmonary embolism. DIAGNOSES A primary endovascular EHE pulmonary endovascular epithelioid hemangioendothelioma was diagnosed by endovascular biopsy with positive stains for molecular CD31, CD34 and CAMTA1, and it had low proliferative capacity characterized by Ki-67 of 5%. The mutation gene MSH2 (p.Y656 in exon 12) (mutation abundance of 0.07%) from peripheral blood indicates the potential benefit of an immune checkpoint inhibitor, pembrolizumab. INTERVENTIONS AND OUTCOMES The patient was treated with tri-weekly paclitaxel (175mg/m2) and carboplatin (AUC 5) chemotherapy regimen. He exerted a remarkable response after 5 cycles (21 days per cycle) and Pembrolizumab (200mg once monthly) as maintenance treatment. LESSONS This case highlights the diagnostic challenge of differentiating endovascular lesions and optimal therapy for pulmonary EHE. Importantly, it indicated that the mutation gene MSH2 (p.Y656) might influence the pathogenesis of EHE.

Abstract
BACKGROUND Epithelioid hemangioendothelioma (EHE) is an extremely rare tumor with a prevalence of one in a million and a very heterogenous spectrum of disease that varies from an indolent to a metastasizing aggressive disease, with the liver, lung and bone being the primarily involved organs. Peritoneal forms of EHE are even rare, and only 12 cases have been reported to date in the literature.
CASE SUMMARY A 66-year-old female came to our attention complaining low abdominal and perineal pain. Magnetic resonance imaging examination showed a 52 mm × 58 mm × 32 mm cystic mass with some smooth septa, simulating an ovarian cyst. Explorative laparoscopy demonstrated the presence of a peritoneal mass of augmented consistency connected with a sigmoid epiploic appendix in the right side of the Pouch of Douglas, that was surgically removed. Histological exa-mination revealed a primitive peritoneafl hemangioendothelioma. The patient easily recovered from surgery with no residual pain or discomfort. She is regularly attending a 3-years follow-up that is negative for local recurrence of disease or distant metastases.
CONCLUSION Peritoneal form of EHE often simulates masses of other nature, as in our case. Given its unspecific clinical and radiological presentation, patients are often forced to a large series of tests and examinations before reaching a definitive diagnosis, that can only histologically made. The possibility of EHE should always be considered in case of unexplained chronic abdominal pain associated to a non-specific mass.

Abstract
A 49-year-old woman was admitted to our hospital because of haemoptysis for 6 days. This patient claimed no medical history except high blood sugar. Chest computed tomography (CT) showed infection and multiple nodules on both sides of the lung. Blood tests showed no obvious abnormalities. Tracheoscopy showed haemorrhagic discharge in the left upper lobe and an old thrombus obstructing the lumen in the anterior basal segment of the right lower lobe. Then, CT-guided percutaneous lung biopsy was performed. The pathological results suggested multiple nodular-like lesions in the submitted tissues, and tumour cells were round or short fusiform, forming a solid nest structure, visible mitosis, and a vascular cavity-like structure containing red blood cells. Immunohistochemistry revealed positive staining for Vimentin, Bcl-2, CD31, and CD34; negative staining for CD68, SMA, CR, and D2-40; and 40% Ki67+ positivity. Based on the earlier data, the patient was diagnosed with pulmonary epithelioid haemangioendothelioma. This patient did not receive any treatment for several reasons. Unfortunately, the patient died 8 weeks after diagnosis. In conclusion, we present a case featuring the rapid death due to PEH.

Abstract
The authors report a rare case of hemangioendothelioma of the right innominate vein complicated by superior vena cava syndrome. Considering development of enlarged venous collaterals, we performed circular resection of superior vena cava together with the right and left innominate veins without replacement. There were no postoperative complications. The use of vascular prosthesis in patients with long-standing superior vena cava compression and enlarged collaterals is associated with high risk of thrombosis and subsequent pulmonary embolism. Safe circular resection of superior vena cava without replacement is possible after intraoperative test clamping.

Abstract
Epithelioid hemangioendothelioma (EHE) is a rare vascular tumor and the mediastinal localization is amongst the most infrequent. We present the case of a 37-year-old woman with a history of resected left thyroid tumor that presented to our department for evaluation of a left supraclavicular palpable mass in close contact with local vascular structures, and with heterogeneous contrast enhancement as described by computed tomography (CT) and magnetic resonance imaging (MRI). Considering the history of the patient, the presumptive diagnosis of thyroid tumor recurrence was established, and the patient was referred to surgical department. During procedure, we encountered important bleeding from a ruptured jugular vein branch, which we assumed to be a newly formed tumor blood vessel. After surgery (48 hours postoperatively), the patient developed important local thrombosis that encompassed the left internal jugular vein, left subclavian vein and the left brachiocephalic trunk that partially subsided after anticoagulant therapy. The histological examination revealed the presence of a vascular tumor proliferation of epithelioid endothelial cells that was characteristic of an EHE confirmed later on the immunohistochemical studies as Yes-associated protein 1-transcription factor E3 (YAP1-TFE3) subtype. In addition to the case report, some relevant information from the scarce literature data about mediastinal EHE were reviewed here.

Abstract
Cats and dogs are treated as family members by most pet owners. Therefore, a high quality of veterinary care and preventive medicine is imperative for animal health and welfare and for the protection of humans from zoonotic pathogens. There is a general perception of cats being treated as "small dogs," especially in the field of clinical parasitology. As a result, several important differences between the two animal species are not taken into proper consideration and are often overlooked. Dogs and cats are profoundly different under evolutionary, biological, ethological, behavioral, and immunological standpoints. These differences impact clinical features, diagnosis, and control of canine and feline parasites and transmission risk for humans. This review outlines the most common parasitoses and vector-borne diseases of dogs and cats, with a focus on major convergences and divergences, and discusses parasites that have (i) evolved based on different preys for dogs and cats, (ii) adapted due to different immunological or behavioral animal profiles, and (iii) developed more similarities than differences in canine and feline infections and associated diseases. Differences, similarities, and peculiarities of canine and feline parasitology are herein reviewed in three macrosections: (i) carnivorism, vegetarianism, anatomy, genetics, and parasites, (ii) evolutionary adaptation of nematodes, including veterinary reconsideration and zoonotic importance, and (iii) behavior and immune system driving ectoparasites and transmitted diseases. Emphasis is given to provide further steps toward a more accurate evaluation of canine and feline parasitology in a changing world in terms of public health relevance and One Health approach.

[PMID: 34944821 PMCID: PMC8699575 DOI: 10.3390/cancers13246201] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Revised: 12/03/2021] [Accepted: 12/07/2021] [Indexed: 12/13/2022] Open
Abstract
Simple Summary Malignant vascular tumors are extremely rare tumors with variable clinical courses, and few data on their clinical management are available. Diagnosis is difficult due to their wide morphologic appearance. The intent of the present review is to demonstrate the current knowledge and management on malignant vascular tumors of the head and neck area. The mainstay of treatment for malignant vascular tumors is surgery, but radiotherapy and chemotherapy are also parts of the treatment concept especially in angiosarcomas. Targeted therapy, antiangiogenetic drugs and immunotherapy have been studied as new treatment options. Abstract Malignant vascular tumors of the head and neck are rare neoplasms with variable clinical presentation, wide age distribution, and variable clinical courses. The heterogeneous presentation of angiosarcomas and epithelioid hemangioendothelioma often leads to misdiagnosis and unsuitable treatment. While risk factors for angiosarcomas are previous radiation, chronic lymphedema, and exposure to arsenic, thorium oxide, or vinyl chloride, there are only limited and retrospective data available on prognostic factors in EHE. In both angiosarcomas and EHE, surgery is the mainstay of treatment. There is limited evidence regarding the role of radiotherapy in EHE, although EHE is considered relatively radiosensitive. In angiosarcomas, adjuvant radiotherapy is recommended according to retrospective case series. A standard medical therapy for metastasized malignant vascular tumors is lacking. Chemotherapy, which is effective in angiosarcoma, is mostly ineffective in EHE. Targeted therapy, antiangiogenetic drugs and immunotherapy have been studied as new treatment options. The goal of this review is to summarize the current data regarding malignant vascular tumors along with their diagnosis and management.

Abstract
Background Malignant vascular tumors (MVTs) are rare and often misdiagnosed due to wide range of clinical presentations, varied histology, and exquisite imagining features. We aim to characterize two different types of MVTs of the liver: hepatic angiosarcomas (HA) and hepatic epithelioid hemangioendotheliomas (HEHE). Methods Data on HA and HEHE between 1975 and 2016 were extracted from the SEER database and analyzed. Results A total of 366 patients with HA were identified where 64.2% were male and 79% of White race. The median age at diagnosis was 64 ± 16.2 years. Distant metastasis was found in 24% of patients, regional disease in 22.1%, and localized disease in 21.3%. The median overall survival for HA was 2 months. For HEHE, 120 cases were identified, 32.5% were male and 80% of White race. The median age of diagnosis was 51 ± 16.8 years. Distant metastasis was found in 37.5% of patients, regional disease in 27.5%, and localized disease in 20%. The median overall survival was 182 months. Conclusion Patients’ demographics such as race, age, and gender may assist in elucidating distinct subtypes of MVTs. HA is an aggressive tumor despite intervention. Patients with HEHE tumors have significantly better survival compared to patients with HA. Further studies are needed to deepen our knowledge about the histopathology of these tumors, the outcomes of liver transplantation as a therapeutic alternative, and available molecular targets for MVTs.

Abstract
Hepatic EHE (epithelioid hemangioendothelioma) is an uncommon entity of vascular origin and a low-grade malignant tumor. Primary hepatic EHE is rare. These tumors can be multifocal at presentation like in the soft tissues, bones, brain, liver, and small intestine. First described by Weiss and Enzinger in 1982 as a malignant vascular neoplasm with indolent behavior. We report the case of a 23-year-old male, known case of chronic liver disease, who presented with incisional hernia following exploratory laparotomy 8 months back, performed for intestinal obstruction. Contrast-enhanced computed tomography abdomen revealed an incisional hernia with a large defect along with multiple lesions in the liver (suspected metastases) and peritoneal deposits and a few discrete lung nodules. Some areas of interloop collections were also noted. Biopsies were taken from the liver which revealed benign cirrhotic lesion. Relevant to the findings, multiple biopsies were performed and fluid was sent for evaluation. The liver biopsy came out positive for borderline vascular malignancy (epithelioid hemangioendothelioma). This was confirmed with the immunohistochemistry report. Epithelioid hemangioendothelioma occurs mostly in soft tissues of extremity and lungs. The involvement of the liver may be seen as metastasis or rarely as a primary tumor. The incidence of primary malignant hepatic hemangioendothelioma is about 0.1/100,000; the mean age at the time of diagnosis is 41.7 years, and male:female ratio is 2:3. Liver transplantation, hepatectomy, chemoembolization, radiotherapy, and chemotherapeutic agents are reported treatment regimens. Malignant EHE of liver presents as multiple hepatic nodules. Being locally aggressive, it can invade the peritoneum, gut, and lungs. Orthoptic liver transplantation appears to be the only remedy because of the multifocal nature of the disease. Partial hepatectomy is possible for localized tumors.

Abstract
OBJECTIVE. The purpose of this article is to review the spectrum of imaging manifestations of epithelioid hemangioendothelioma across different organ systems and briefly describe its current treatment strategies. CONCLUSION. Epithelioid hemangioendothelioma is a rare, locally invasive neoplasm with metastatic potential. Although most commonly occurring in liver, lungs, and bones, it can also present at multiple other sites. Because of its nonspecific clinical and imaging manifestations, it is often misdiagnosed. The possibility of epithelioid hemangioendothelioma must be considered in the presence of a slowly growing mass that invades adjacent structures. Imaging can help plan percutaneous biopsy, detect sites of disease, and identify poor prognostic factors.

Abstract
BACKGROUND Pulmonary epithelioid hemangioendothelioma (P-EHE) is a rare disease. Thus far, consensus on a standard treatment for P-EHE has not been established given its low incidence worldwide. Apatinib combined with chemotherapy with doxorubicin/cyclophosphamide has been used as an effective combination treatment for human malignancies. However, the efficacy of this combination has not been reported in P-EHE cases.
CASE SUMMARY We present the case of a 64-year-old woman with chest tightness, cough, and chest pain. Computed tomography showed multiple unresectable pulmonary nodules. She had been misdiagnosed with lung carcinoma and underwent gefitinib treatment at a hospital. Subsequently, the patient underwent a cardiothoracic surgery for further disease investigation. CD31, CD34, and Vimentin expression were detected in the resected nodule specimens by immunohistochemical analyses, and pathological analyses confirmed the diagnosis of P-EHE. Following this, four cycles of apatinib combined with chemotherapy with doxorubicin/cyclophosphamide were initiated. The patient demonstrated stabilization of multiple bilateral nodules and showed a dramatic improvement in the clinical presentation after combination treatment. The patient could not tolerate the side effects of chemotherapy. Therefore, she then continued apatinib monotherapy, which is ongoing to date. The patient was stable at the last follow-up after 24 mo.
CONCLUSION Apatinib combined with chemotherapy with doxorubicin/cyclophosphamide may be an effective therapeutic option for P-EHE treatment.

Hepatic hemangioendothelioma: CT, MR, and FDG-PET-CT in 67 patients-a bi-institutional comprehensive cancer center review. Eur Radiol 2020; 30:2435-2442. [PMID: 32002639 DOI: 10.1007/s00330-019-06637-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2019] [Revised: 11/26/2019] [Accepted: 12/16/2019] [Indexed: 12/12/2022]
Abstract
OBJECTIVE To evaluate the imaging features of hepatic epithelioid hemangioendothelioma (HEH) on multiphasic CT, MR, and FDG-PET-CT. METHODS Bi-institutional review identified 67 adults (mean age, 47 years; 23 M/44 F) with pathologically proven HEH and pretreatment multiphasic CT (n = 67) and/or MR (n = 30) and/or FDG-PET-CT (n = 13). RESULTS HEHs were multifocal in 88% (59/67). Mean size of the dominant mass was 4.1 cm (range, 1.4-19 cm). The tumors were located in the peripheral, subcapsular regions of the liver in 96% (64/67). Capsular retraction was present in 81% (54/67 cases) and tumors were coalescent in 61% (41/67). HEH demonstrated peripheral ring enhancement on arterial phase imaging in 33% (21/64) and target appearance on the portal venous phase in 69% (46/67). Persistent peripheral enhancement on the delayed phase was seen in 49% (31/63). On MR, multilayered target appearance was seen on the T2-weighted sequences in 67% (20/30) and on the diffusion-weighted sequences in 61% (11/18). Target appearance on hepatobiliary phase of MRI was seen in 57% (4/7). On pre-therapy FDG-PET-CT, increased FDG uptake above the background liver parenchyma was seen in 62% (8/13). CONCLUSION HEHs typically manifest as multifocal, coalescent hepatic nodules in peripheral subcapsular location, with associated capsular retraction. Peripheral arterial ring enhancement and target appearance on portal venous phase are commonly seen on CT. Similarly, multilayered target appearance correlating with its histopathological composition is typically seen on multiple sequences of MR including T2-weighted, diffusion-weighted, and dynamic contrast-enhanced multiphasic MR. KEY POINTS • Hepatic epithelioid hemangioendotheliomas manifest on CT and MR as multifocal, coalescent hepatic nodules in peripheral subcapsular location, with associated capsular retraction. • Enhancement pattern on contrast-enhanced CT and MR can vary but peripheral ring enhancement on arterial phase and target appearance on portal venous phase are commonly seen. • Retrospective two-center study showed that cross-sectional imaging may help in the diagnosis.

Abstract
Hemangiosarcoma (HSA), a locally invasive and highly metastatic endothelial cell neoplasm, accounts for two-thirds of all cardiac and splenic neoplasms in dogs. Bartonella spp. infection has been reported in association with neoplastic and non-neoplastic vasoproliferative lesions in animals and humans. The objective of this study was to determine the prevalence of Bartonella spp. in conjunction with two other hemotropic pathogens, Babesia spp. and hemotropic Mycoplasma spp., in tissues and blood samples from 110 dogs with histopathologically diagnosed HSA from throughout the United States. This was a retrospective, observational study using clinical specimens from 110 dogs with HSA banked by the biospecimen repository of the Canine Comparative Oncology and Genomics Consortium. Samples provided for this study from each dog included: fresh frozen HSA tumor tissue (available from n = 100 of the 110 dogs), fresh frozen non-tumor tissue (n = 104), and whole blood and serum samples (n = 108 and 107 respectively). Blood and tissues were tested by qPCR for Bartonella, hemotropic Mycoplasma, and Babesia spp. DNA; serum was tested for Bartonella spp. antibodies. Bartonella spp. DNA was amplified and sequenced from 73% of dogs with HSA (80/110). In contrast, hemotropic Mycoplasma spp. DNA was amplified from a significantly smaller proportion (5%, p<0.0001) and Babesia spp. DNA was not amplified from any dog. Of the 100 HSA tumor samples submitted, 34% were Bartonella PCR positive (32% of splenic tumors, 57% of cardiac tumors, and 17% of other tumor locations). Of 104 non-tumor tissues, 63% were Bartonella PCR positive (56% of spleen samples, 93% of cardiac samples, and 63% of skin/subcutaneous samples). Of dogs with Bartonella positive HSA tumor, 76% were also positive in non-tumor tissue. Bartonella spp. DNA was not PCR amplified from whole blood. This study documented a high prevalence of Bartonella spp. DNA in dogs with HSA from geographically diverse regions of the United States. While 73% of all tissue samples from these dogs were PCR positive for Bartonella DNA, none of the blood samples were, indicating that whole blood samples do not reflect tissue presence of this pathogen. Future studies are needed to further investigate the role of Bartonella spp. in the development of HSA.

Abstract
Epithelioid hemangioendothelioma (EHE) is a rare vascular neoplasm that develops from vascular endothelial cells. It has been reported to occur many sites of body, but the most common EHE presentations are soft tissue (limbs), bone, liver and lung. Compared with other pulmonary tumors, pulmonary epithelioid hemangioendothelioma (P-EHE) is relatively rare. According to a literature review, more than 100 cases have been described all over the world. Due to the low incidence of P-EHE, lack of specificity in clinical symptoms and radiological findings, it is often misdiagnosed. Meanwhile, many patients do not receive appropriate treatment, resulting in poor prognosis in some cases. Histology and immunohistochemical methods are essential for diagnosis. However, there is no established standard treatment for P-EHE, because of the rarity of the disease. When the lesions are small and limited in number, surgical is the best treatment, achieving the purpose of diagnosis and treatment at the same time. This article tries to present the etiopathogenesis, clinical manifestations, diagnosis, treatment and prognosis of P-EHE.

Abstract
Historically, Bartonella spp. have been associated with febrile illness (Oroya fever, trench fever, and cat scratch disease), endocarditis (numerous Bartonella spp.), and vasoproliferative lesions (Bartonella bacilliformis, Bartonella quintana, Bartonella henselae, and Bartonella vinsonii subsp. berkhoffii), occurring most often but not exclusively in immunocompromised patients. Recently, bloodstream infections with various Bartonella spp. have been documented in nonimmunocompromised individuals in association with a spectrum of cardiovascular, neurologic, and rheumatologic symptoms. As documented in this family, symptoms for which the medical implications remain unclear can occur in multiple family members infected with one or more Bartonella spp. Serial serologic and molecular microbiological findings supported exposure to or infection with Bartonella spp. in all seven family members. Either antibiotics failed to eliminate bacteremic infection, resulted in partial resolution of symptoms, or potentially reinfection occurred during the 19-month study period. There is a substantial need for clinical research to clarify the extent to which Bartonella spp. bacteremia induces nonspecific cardiovascular, neurologic, or rheumatologic symptoms, for ongoing improvement in the sensitivity and specificity of diagnostic testing, and clarification as to if, when, and how to treat patients with documented Bartonella spp. bacteremia.

Abstract
Vascular tumours of the liver represent an underrated chapter of medical and surgical hepatology. These tumours cover a wide spectrum ranging from the frequent and most benign hepatic haemangioma (HH), via the rare and intermediately aggressive hepatic epithelioid haemangioendothelioma (HEHE) to the rare and most malignant hepatic haemangiosarcoma (HHS). In contrast to the treatment algorithms for hepatocellular and cholangiocellular cancer, the diagnostic and therapeutic approaches to HEHE and HHS are not well developed. The related uncertainty is explained by their rare occurrence and their protean clinical, morphological (imaging) and histopathological presentation and behaviour. This article gives an update about these particular tumours based on the analysis of the recent literature and of the studies on vascular tumours published by the European Liver Intestine Transplantation Association (ELITA)-European Liver Transplant Registry (ELTR). It focuses also on the place of liver transplantation (LT) in the respective therapeutic algorithms. The differential diagnosis between these vascular and other tumour types may be very difficult. Correct diagnosis is of utmost importance and is based on a high index of clinical suspicion and on the integration of clinical, radiological, histological [including immunohistochemistry (IHC) and molecular biology findings]. Surgery, be it partial or total hepatectomy (LT), should be proposed whenever possible, because it is the therapeutic mainstay. In HEHE, LT provides excellent results, with long-term disease-free survivals (DFS) reaching 75%. Good results can be obtained even in case of (frequent) extrahepatic spread. Based on the extensive ELITA-ELTR study a HEHE-LT prognostic score has been proposed in order to estimate the risk of recurrence after LT. In contrast, results of surgery and LT are extremely poor for HHS, for the almost invariably rapid recurrence (within 6 months) and related death within 2 years. LT remains a contraindication for HHS. Due to the still important recurrence rate after surgical resection (25% in HEHE and almost 100% in HHS), there is an urgent need to develop pharmacological treatments targeting angiogenic and non-VEGF angiogenic pathways. To date, some prospective pilot studies and case reports have shown some short-term stabilisation of the disease in small groups of patients. In order to make progress, combination of surgery, anti-angiogenic and immunotherapy seems worthwhile. To complete the panel of vascular liver tumours, infantile haemangioendothelioma, haemangiopericytoma, nodular regenerative hyperplasia (NRH) and hepatic small vessel neoplasms (HSVN) are also discussed.

Abstract
An epithelioid hemangioendothelioma (EHE) is a rare vascular tumor of the head and neck region, which carries a risk of recurrence and metastasis. Its etiology is still unclear. It frequently involves the lungs, liver, and bones. Rarely, it may manifest in other parts of the body. Pathologic immunohistochemical investigations are essential to make the definite diagnosis. As it is uncommon, there is no standardized protocol for the treatment of EHE. Herein, the authors report a rare patient with of an EHE localized in the head and neck region.

Abstract
Pulmonary epithelioid hemangioendothelioma (PEH) is a rare neoplasm of vascular origin. There are three different major imaging patterns identified in thoracic manifestation of epithelioid hemangioendothelioma: (1) multiple pulmonary nodules; (2) multiple pulmonary reticulonodular opacities; and (3) diffuse infiltrative pleural thickening. Radiographically, presence of bilateral multiple nodules is the most common pattern of presentation. The diagnosis is made on the basis of histopathological findings and confirmed by positive immunohistochemistry staining. Although the prognostic factors for PEH have not yet been well established, a better prognosis is usually associated with the multinodular pattern. We report two different imagological presentations of this rare disease, based on two institutional experiences, along with a review of the relevant literature.

Abstract
BACKGROUND Bartonellosis is a zoonotic infectious disease of worldwide distribution, caused by an expanding number of recently discovered Bartonella spp. OBJECTIVES This review serves as an update on comparative medical aspects of this disease, including the epidemiology, pathogenesis, clinical diagnosis, treatment and challenges. RESULTS Of comparative medical importance, Bartonella spp. are transmitted by several arthropod vectors, including fleas, keds, lice, sand flies, ticks and, potentially, mites and spiders. Prior to 1990, there was only one named Bartonella species (B. bacilliformis), whereas there are now over 36, of which 17 have been associated with an expanding spectrum of animal and human diseases. Recent advances in diagnostic techniques have facilitated documentation of chronic bloodstream and dermatological infections with Bartonella spp. in healthy and sick animals, in human blood donors, and in immunocompetent and immunocompromised human patients. The field of Bartonella research remains in its infancy and is rich in questions, for which patient relevant answers are badly needed. Directed Bartonella research could substantially reduce a spectrum of chronic and debilitating animal and human diseases, and thereby reduce suffering throughout the world. CONCLUSION A One Health approach to this emerging infectious disease is clearly needed to define disease manifestations, to establish the comparative infectious disease pathogenesis of this stealth pathogen, to validate effective treatment regimens and to prevent zoonotic disease transmission.

Abstract
BACKGROUND Epithelioid haemangioendothelioma (EHE) is a rare low-grade vascular neoplasm that can arise in the lung, liver, soft tissues or, less commonly, bone. Due to its low prevalence of less than one in a million and its non-specific clinical features, EHE is often misdiagnosed and managed inappropriately. Here we discuss the case of a 58 year-old gentleman with mediastinal EHE and review existing literature on pulmonary EHE (PEH). CASE HISTORY A 58 year-old gentleman presented to our outpatient Clinic with chest discomfort and palpitations. A whole-body FDG-CT-PET showed an FDG-avid single 6.3cm nodule in the superior anterior mediastinum which was fully excised by robotic approach. Histology showed a nodular structure with clusters of epithelioid and spindled cells with a low proliferative index and mitotic count, suspended in a sclerotic stroma. Immunohistochemistry staining was positive for CD3 and CD34, confirming endothelial lineage, and SMA, identifying smooth muscle clusters. DISCUSSION PEH typically presents in young Caucasian women, either incidentally as multiple small pulmonary nodules on CT or with respiratory symptoms that include cough, dyspnoea, chest pain and occasionally pleural effusions. Aetiology and prognosis remain unclear, although indicators of poor prognosis include the presence of respiratory symptoms, male gender, older age and multi-organ disease. Diagnosis is difficult and PEH is often misidentified as chronic granulomatous disease, amyloidosis or other malignancy of the lung. Histological features suggestive of PEH include nodules of hypocellular sclerotic stroma containing spindle-shaped tumour cells with abundant eosinophilic cytoplasm, vacuoles containing erythrocytes and low mitotic counts. CD31, CD34 and Fli-1 positive immunohistochemistry is strongly indicative of epithelioid lineage. There is no standard treatment for PEH but curative resection is the preferred treatment option where possible, with chemotherapy being used as adjuvant treatment or in widespread inoperable disease. CONCLUSION This case report outlines the clinicopathological features that are characteristic of EHE with the hope of facilitating correct and early diagnosis in the future.

Abstract
These bacteria may cause paucisymptomatic bacteremia and endocarditis in humans. Certain Bartonella species are known to cause afebrile bacteremia in humans and other mammals, including B. quintana, the agent of trench fever, and B. henselae, the agent of cat scratch disease. Reports have indicated that animal-associated Bartonella species may cause paucisymptomatic bacteremia and endocarditis in humans. We identified potentially zoonotic strains from 6 Bartonella species in samples from patients who had chronic, subjective symptoms and who reported tick bites. Three strains were B. henselae and 3 were from other animal-associated Bartonella spp. (B. doshiae, B. schoenbuchensis, and B. tribocorum). Genomic analysis of the isolated strains revealed differences from previously sequenced Bartonella strains. Our investigation identifed 3 novel Bartonella spp. strains with human pathogenic potential and showed that Bartonella spp. may be the cause of undifferentiated chronic illness in humans who have been bitten by ticks.

Abstract
Bartonella species constitute emerging, vector-borne, intravascular pathogens that produce long-lasting bacteremia in reservoir-adapted (natural host or passive carrier of a microorganism) and opportunistic hosts. With the advent of more sensitive and specific diagnostic tests, there is evolving microbiological evidence supporting concurrent infection with one or more Bartonella spp. in more than one family member; however, the mode(s) of transmission to or among family members remains unclear. In this study, we provide molecular microbiological evidence of Bartonella henselae genotype San Antonio 2 (SA2) infection in four of six Danish family members, including a child who died of unknown causes at 14 months of age.

Abstract
INTRODUCTION Epitheloid hemangioendothelioma is a rare vascular soft tissue tumour of intermediate malignant potential. The tumor affects any age group, and liver is the commonest internal organ affected. Bones as calvarium, spine, tibia and femur may also be affected. The lesion can be multifocal in the liver or the same bone itself and can metastasise to lungs. Here we report a rare case of epithelioid hemangioendothelioma involving tibia in a male infant, which regressed by itself without any treatment, after incisional biopsy over a period of one and half years. CASE REPORT A 7 month old male baby was presented with incessant cry, fever and swelling in left upper leg of 2 weeks duration. X-ray of leg showed a well demarcated lytic lesion in the meta diaphysial region of left tibia. Magnetic resonance imaging showed an irregular lytic lesion with intramedullary extension. Incisional biopsy showed a vascular tumor, epithelioid hemangioendothelioma grade 1. Meanwhile the patient became asymptomatic and subsequent follow ups showed regression in the size of the tumor and complete disappearance after one and half years. This points towards the need of a wait and watch policy in such intermediate grade vascular tumours even though the lesion is so extensive. This is the first case report of an extensive self regressing epithelioid hemangioendothelioma of tibia in an infant to our knowledge. CONCLUSION Intermediate grade vascular tumors can undergo spontaneous regression which points towards the need of a wait and watch policy in such tumors thus avoiding extensive surgeries, especially in young patients.

Abstract
Background Borrelia burgdorferi is the causative agent of Lyme borreliosis. This spirochete, along with Babesia, Bartonella, Anaplasma, Ehrlichia, and the Rickettsia spp. are recognized tick-borne pathogens. In this study, the clinical manifestation of these zoonoses in Australia is described. Methods The clinical presentation of 500 patients over the course of 5 years was examined. Evidence of multisystem disease and cranial nerve neuropathy was sought. Supportive laboratory evidence of infection was examined. Results Patients from every state of Australia presented with a wide range of symptoms of disease covering multiple systems and a large range of time intervals from onset. Among these patients, 296 (59%) were considered to have a clinical diagnosis of Lyme borreliosis and 273 (54% of the 500) tested positive for the disease, the latter not being a subset of the former. In total, 450 (90%) had either clinical evidence for or laboratory proof of borrelial infection, and the great majority of cases featured neurological symptoms involving the cranial nerves, thus mimicking features of the disease found in Europe and Asia, as distinct from North America (where extracutaneous disease is principally an oligoarticular arthritis). Only 83 patients (17%; number [n]=492) reported never leaving Australia. Of the 500 patients, 317 (63%) had clinical or laboratory-supported evidence of coinfection with Babesia or Bartonella spp. Infection with A. phagocytophilum was detected in three individuals, and Ehrlichia chaffeensis was detected in one individual who had never traveled outside Australia. In the cohort, 30 (11%; n=279) had positive rickettsial serology. Conclusion The study suggests that there is a considerable presence of borreliosis in Australia, and a highly significant burden of coinfections accompanying borreliosis transmission. The concept sometimes advanced of a “Lyme-like illness” on the continent needs to be re-examined as the clinical interplay between all these infections. Evidence is presented for the first report of endemic anaplasmosis and ehrlichiosis on the continent.

Abstract
Epithelioid hemangioendothelioma is a rare vascular tumor, described for the first time in 1975 by Dail and Liebow as an aggressive bronchoalveolar cell carcinoma. The etiology is still a dilemma. Studies about suggestive hypothesis are ongoing. Most of the times it affects lung, liver and bones, although this kind of tumor may involve the head and neck area, breast, lymph nodes, mediastinum, brain and meninges, the spine, skin, abdomen and many other sites. Because of its heterogeneous presentation, as it represents less than 1% of all the vascular tumors, it is often misdiagnosed and not suitably treated, leading to a poor prognosis in some cases. Over 50-76% of the patients are asymptomatic. A small number of them complains respiratory symptoms. Bone metastases might cause pathological fractures or spine compression, if they arise in vertebrae. Imaging is necessary to determine morphological data, the involvement of surrounding tissues, and potentially the cleavage plan. It is important to recognize the expression of vascular markers (Fli-1 and CD31 are endothelial-specific markers), and the microscopic evidence of vascular differentiation to make a correct diagnosis, as many pulmonary diseases show multiple nodular lesions. Because of its rarity, there is no standard for treatment. We focused on radiotherapy as a good therapeutic option: despite the poor prognosis, evidence is in favor of radiotherapy which offers local pain control with good tolerance and better quality of life at least at a one-year follow-up in most of cases. Further studies are needed to establish the standard radiation dose to be used for locoregional control of such a complex and extremely rare disease.

Bartonella henselae infection in a family experiencing neurological and neurocognitive abnormalities after woodlouse hunter spider bites. Parasit Vectors 2013; 6:98.

Abstract
BACKGROUND Bartonella species comprise a group of zoonotic pathogens that are usually acquired by vector transmission or by animal bites or scratches. METHODS PCR targeting the Bartonella 16S-23S intergenic spacer (ITS) region was used in conjunction with BAPGM (Bartonella alpha Proteobacteria growth medium) enrichment blood culture to determine the infection status of the family members and to amplify DNA from spiders and woodlice. Antibody titers to B. vinsonii subsp. berkhoffii (Bvb) genotypes I-III, B. henselae (Bh) and B. koehlerae (Bk) were determined using an IFA test. Management of the medical problems reported by these patients was provided by their respective physicians. RESULTS In this investigation, immediately prior to the onset of symptoms two children in a family experienced puncture-like skin lesions after exposure to and presumptive bites from woodlouse hunter spiders. Shortly thereafter, the mother and both children developed hive-like lesions. Over the ensuing months, the youngest son was diagnosed with Guillain-Barre (GBS) syndrome followed by Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP). The older son developed intermittent disorientation and irritability, and the mother experienced fatigue, headaches, joint pain and memory loss. When tested approximately three years after the woodlouse hunter spider infestation, all three family members were Bartonella henselae seroreactive and B. henselae DNA was amplified and sequenced from blood, serum or Bartonella alpha-proteobacteria (BAPGM) enrichment blood cultures from the mother and oldest son. Also, B. henselae DNA was PCR amplified and sequenced from a woodlouse and from woodlouse hunter spiders collected adjacent to the family's home. CONCLUSIONS Although it was not possible to determine whether the family's B. henselae infections were acquired by spider bites or whether the spiders and woodlice were merely accidental hosts, physicians should consider the possibility that B. henselae represents an antecedent infection for GBS, CIDP, and non-specific neurocognitive abnormalities.

Abstract
BACKGROUND Bartonella henselae is a zoonotic, alpha Proteobacterium, historically associated with cat scratch disease (CSD), but more recently associated with persistent bacteremia, fever of unknown origin, arthritic and neurological disorders, and bacillary angiomatosis, and peliosis hepatis in immunocompromised patients. A family from the Netherlands contacted our laboratory requesting to be included in a research study (NCSU-IRB#1960), designed to characterize Bartonella spp. bacteremia in people with extensive arthropod or animal exposure. All four family members had been exposed to tick bites in Zeeland, southwestern Netherlands. The mother and son were exhibiting symptoms including fatigue, headaches, memory loss, disorientation, peripheral neuropathic pain, striae (son only), and loss of coordination, whereas the father and daughter were healthy. METHODS Each family member was tested for serological evidence of Bartonella exposure using B. vinsonii subsp. berkhoffii genotypes I-III, B. henselae and B. koehlerae indirect fluorescent antibody assays and for bacteremia using the BAPGM enrichment blood culture platform. RESULTS The mother was seroreactive to multiple Bartonella spp. antigens and bacteremia was confirmed by PCR amplification of B. henselae DNA from blood, and from a BAPGM blood agar plate subculture isolate. The son was not seroreactive to any Bartonella sp. antigen, but B. henselae DNA was amplified from several blood and serum samples, from BAPGM enrichment blood culture, and from a cutaneous striae biopsy. The father and daughter were seronegative to all Bartonella spp. antigens, and negative for Bartonella DNA amplification. CONCLUSIONS Historically, persistent B. henselae bacteremia was not thought to occur in immunocompetent humans. To our knowledge, this study provides preliminary evidence supporting the possibility of persistent B. henselae bacteremia in immunocompetent persons from Europe. Cat or flea contact was considered an unlikely source of transmission and the mother, a physician, reported that clinical symptoms developed following tick exposure. To our knowledge, this is the first time that a B. henselae organism has been visualized in and amplified from a striae lesion. As the tick bites occurred three years prior to documentation of B. henselae bacteremia, the mode of transmission could not be determined.

Abstract
In his homage to Lucretius (‘Georgica’), Vergil is credited with stating: ‘Felix qui potuit rerum cognoscere causas’ (‘Fortunate is he who knows the causes of things’). Based on numerous commentaries and publications it is obvious that clinicians, diagnosticians and biomedical research scientists continue to struggle with disease causation, particularly in the assessment of the pathogenic role of ‘stealth pathogens’ that produce persistent infections in the host. Bartonella species, because of their evolutionary ability to induce persistent intravascular infections, present substantial challenges for researchers attempting to clarify the ability of these stealth bacteria to cause disease. By studying the comparative biological and pathological behaviour of microbes across mammalian genera, researchers might be able more rapidly to advance medical science and, subsequently, patient care by undertaking focused research efforts involving a single mammalian species or by attempting to recapitulate a complex disease in an rodent model. Therefore, in an effort to further assist in the establishment of disease causation by stealth pathogens, we use recent research observations involving the genus Bartonella to propose an additional postulate of comparative infectious disease causation to Koch's postulates.

Abstract
Bartonella spp. are facultative intracellular bacteria that typically cause a long-lasting intraerythrocytic bacteremia in their mammalian reservoir hosts, thereby favoring transmission by blood-sucking arthropods. In most cases, natural reservoir host infections are subclinical and the relapsing intraerythrocytic bacteremia may last weeks, months, or even years. In this review, we will follow the infection cycle of Bartonella spp. in a reservoir host, which typically starts with an intradermal inoculation of bacteria that are superficially scratched into the skin from arthropod feces and terminates with the pathogen exit by the blood-sucking arthropod. The current knowledge of bacterial countermeasures against mammalian immune response will be presented for each critical step of the pathogenesis. The prevailing models of the still-enigmatic primary niche and the anatomical location where bacteria reside, persist, and are periodically seeded into the bloodstream to cause the typical relapsing Bartonella spp. bacteremia will also be critically discussed. The review will end up with a discussion of the ability of Bartonella spp., namely Bartonella henselae, Bartonella quintana, and Bartonella bacilliformis, to induce tumor-like vascular deformations in humans having compromised immune response such as in patients with AIDS.
