Abstract
BACKGROUND Retroperitoneal infantile hemangioma (RIH), a type of primary retroperitoneal tumors, are exceptionally rare in clinical practice. Infantile hemangiomas typically manifest on the skin's surface. RIHs are exceptionally rare and typically small. In adults, these tumors often manifest without specific clinical symptoms or detectable signs for a definitive diagnosis. This case report details a patient diagnosed with RIH. We recommend complete excision of the tumor after a comprehensive evaluation, followed by postoperative pathology, to achieve a conclusive diagnosis. We believe that managing critical retroperitoneal structures and vessels intraoperatively presents a significant challenge for all procedures involving primary retroperitoneal tumors. A 47-year-old male was diagnosed with gallstones and underwent surgery 3 months ago at other institution for unexplained nausea and vomiting. Follow-up imaging 2 months after surgery revealed a retroperitoneal mass below the left renal pole. Upon presentation to our hospital, the patient continued to experience intermittent nausea and vomiting, with no other significant symptoms or signs. Considering the patient's 8-year history of hypertension, a paraganglioma was initially suspected. We performed the laparoscopic mass resection after a detailed assessment. However, postoperative pathology revealed it a capillary hemangioma (old term)/infantile hemangioma. CONCLUSION RIHs are exceedingly rare benign tumor. The possibility of malignancy should be ruled out, and surgical resection is recommended following a thorough evaluation, with the diagnosis confirmed through pathological examination.

Abstract
Soft tissue and bone tumors comprise a wide category of neoplasms. Their diversity frequently raises diagnostic challenges, and therapeutic options are continuously developing. The therapeutic success rate and long-term prognosis of patients have improved substantially due to new advances in immunohistochemical and molecular biology techniques. A fundamental contribution to these achievements has been the study of the tumor microenvironment and the reclassification of new entities with the updating of the molecular pathogenesis in the revised 5th edition of the Classification of Soft Tissue Tumors, edited by the World Health Organization. The proposed molecular diagnostic techniques include the well-known in situ hybridization and polymerase chain reaction methods, but new techniques such as copy-number arrays, multiplex probes, single-nucleotide polymorphism, and sequencing are also proposed. This review aims to synthesize the most recent pathogenetic and molecular classifications of soft tissue and bone tumors, considering the major impact of these diagnostic tools, which are becoming indispensable in clinicopathological practice.

Abstract
BACKGROUND Renal anastomosing hemangioma (AH) is a rare benign vascular tumor characterized by unique histopathological features. CASE SUMMARY We report a highly unusual case of renal AH. A male patient had undergone partial nephrectomy for clear cell carcinoma of the kidney four years prior. A follow-up computed tomography scan in the third postoperative year revealed a new mass near the surgical site on the same side of the kidney, raising suspicions of tumor recurrence. However, the characteristics on contrast-enhanced magnetic resonance imaging and ultrasonography were more consistent with those of a benign lesion. The patient strongly insisted on undergoing surgery due to concerns about the possibility of renal cancer recurrence. Postoperative pathology confirmed the diagnosis of renal AH. CONCLUSION This case report presents the imaging features of a patient with rare renal AH and a history of renal clear cell carcinoma, providing broader insights into the differential diagnosis of new lesions after surgery for renal cell carcinoma.

Primary anastomosing hemangioma as a preoperative diagnostic mimicker of retroperitoneal cavernous hemangioma: A case report. Oncol Lett 2024; 27:254. [PMID: 38646490 PMCID: PMC11027107 DOI: 10.3892/ol.2024.14386] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Accepted: 01/30/2024] [Indexed: 04/23/2024] Open
Abstract
Anastomosing hemangioma (AH) is rare and a newly recognized variant of capillary hemangioma that is mostly found in the genitourinary tract. Additionally, AH is sometimes difficult to diagnose without pathological specimens. It is difficult to diagnose preoperatively due to the lack of specific clinical and radiologic appearance. The present report describes the imaging features from a radiological perspective and outlines the clinicopathologic features and treatment options. A 67-year-old woman was referred to Dokkyo Medical University Saitama Medical Center (Koshigaya, Japan) for a retroperitoneal tumor that was identified at a medical checkup 4 years prior. The patient had no symptoms, no abnormal physical signs and no past medical or specific family history. Routine blood tests were all within the normal ranges. A nonenhanced CT scan showed a circular, homogenous, well-circumscribed retroperitoneal tumor that was ~32×23 mm in size, between the abdominal aorta and the inferior vena cava, and just below the left renal vein. On a contrast-enhanced multidetector CT scan, the tumor showed heterogeneous septal enhancement in the arterial phase and persistent enhancement in the portal phase. The tumor was diagnosed as a benign neurogenic tumor or a retroperitoneal cavernous hemangioma at the time, and the patient was intended to be followed up at the outpatient clinic. However, it gradually increased to a maximum diameter of 35 mm over 4 years. Finally, it was completely resected by open laparotomy and pathologically diagnosed as AH. Retroperitoneal hemangioma is extremely rare in adulthood and has been confirmed in only 1-3% of all retroperitoneal tumors. To the best of our knowledge, only 6 cases of para-aortic AH have been reported. The incidence of this variant is very low. However, AH may be included in the differential diagnosis when a slowly progressing heterogeneous mass appears in the para-aortic region that exhibits a CT-enhanced pattern similar to a typical cavernous hemangioma.

Abstract
With only 15 reported cases, anastomosing haemangioma of adrenal is a rare entity and usually presents as adrenal incidentaloma. A hypertensive, diabetic, non-smoker man in his late 60s presented with irritative voiding symptoms. On evaluation, he was found to have a urinary bladder mass and left adrenal incidentaloma measuring 8 cm. Metabolic evaluation confirmed it to be non-functional.The patient underwent transurethral resection of bladder tumour with left laparoscopic adrenalectomy. Intraoperatively, the adrenal tumour was highly vascular with multiple feeder vessels. Grossly it was soft, encapsulated with focal grey-brown areas. Microscopically, most of adrenal gland was replaced by anastomosing proliferating capillary vessels within framework of non-endothelial supporting cells reminiscent of splenic sinusoids. The tumour was positive for CD-31, CD-34, Glut-1 and SMA.Anastomosing haemangioma is a benign entity but it must be differentiated from angiosarcoma. Characteristic imaging features are not yet defined and is, therefore, difficult to diagnose preoperatively.

Abstract
Anastomosing hemangioma is a rare and benign subtype of capillary hemangioma, a soft tissue tumor. It tends to be asymptomatic, causes abdominal pain and hematuria, and is more common in the genitourinary tract. It can be confused with paragangliomas or ectopic pheochromocytomas. Pathology shares characteristics with angiosarcoma, particularly in well-differentiated areas. Diagnosis without a surgical specimen is difficult and is based on clinical characteristics, laboratories, and imaging behavior similar to hemangiomas in other locations. When in doubt, a diagnosis can be supported by a percutaneous biopsy. The prognosis is good, without relapses or metastases. Early identification with follow-up can avoid surgical interventions.

Abstract
Objective Small series and individual cases of penile soft tissue tumours are reported in the literature: these are rare tumours that represent less than 5% of all penile tumours. Methods Penile soft tissue tumours were collected from the archive of the Department of Pathology at the Istituto Nazionale dei Tumori of Milan between January 1990 and October 2021. All available medical records were retrieved and reviewed to obtain clinical information. Results Our series refers to the 30-year experience of highlighting the heterogeneity in the presentation and microscopic features of these rare sarcomas. 18 penile soft tissue tumours are described, 4 benign and 14 malignant. The mean age at diagnosis was 58.2 years (range 24-96 years) and 53.6 years among malignancies (range 24-89). The most frequent histotype was Kaposi's sarcoma (nr = 4) and very unusual histotypes were observed, namely low-grade fibromyxoid sarcoma, synovial sarcoma, proximal type epithelioid sarcoma and the first reported case of dedifferentiated liposarcoma of the penis. Conclusions Among sarcomas of the genitourinary tract, tumours of the soft tissues of the penis are the rarest. Penile sarcomas can present at a young age. Kaposi's sarcoma in HIV-negative patients has a favorable outcome, while deep sarcomas have an aggressive behavior and poor prognosis.

[PMID: 37936489 DOI: 10.1111/his.15085] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 10/12/2023] [Accepted: 10/14/2023] [Indexed: 11/09/2023]
Abstract
AIMS Anastomosing haemangiomas are benign tumours with anastomosing vascular channels that may mimic angiosarcoma. While anastomosing haemangiomas have been described in diverse locations, particularly the abdominal/paraspinal region, data on anastomosing haemangiomas in the mediastinum remain limited. We report the clinicopathological, radiological and molecular characteristics of the largest single-institutional series of mediastinal anastomosing haemangiomas. METHODS AND RESULTS In our pathology archives in 2011-23, we reviewed all vascular lesions involving the mediastinum and identified seven anastomosing haemangiomas. Clinical information was abstracted from medical charts; available radiological imaging was reviewed. Targeted DNA-based next-generation sequencing (447 genes, including GNAQ and GNA11) was performed on five cases. The seven patients included five women and two men, with an age range of 55-77 (median = 72) years. Of the six tumours with available radiology, two each were in the prevascular, visceral and paravertebral mediastinum, with lobulated peripheral enhancement in all tumours examined with contrast enhancement. Six patients underwent tumour resection; one patient received proton radiotherapy. Microscopically, each tumour was solitary and characterised by anastomosing capillary-sized vessels lined by hobnail endothelial cells. Fibrin microthrombi, hyaline globules and extramedullary haematopoiesis were common. In the five tumours analysed by next-generation sequencing, GNAQ p.Q209P was identified in one tumour; no additional reportable alterations were identified in the remaining cases. No recurrence was noted in the four patients with available follow-up of 3-58 (median = 9.5) months after resection. CONCLUSION While mediastinal anastomosing haemangiomas can microscopically mimic angiosarcoma, awareness of this entity and radiological correlation may help to circumvent this diagnostic pitfall.

Abstract
Vascular lesions of the breast are uncommon, however, these are increasingly encountered now due to more frequent use of magnetic resonance imaging. They comprise a spectrum of lesions including benign, atypical, and malignant tumors. The prototype is a hemangioma, which is most often nonpalpable and is detected on routine screening. Different histopathologic subtypes of hemangioma have been described, including perilobular, venous, cavernous, and capillary hemangioma. Other benign vascular lesions include anastomosing hemangioma, a well-circumscribed proliferation of anastomosing blood vessels with lobular or diffuse growth pattern which affects a large segment of the breast, presenting as a painless slow enlarging palpable mass. Recent data suggest that benign vascular lesions diagnosed on core needle biopsy with concordant radiologic and pathologic findings do not require excision and have an excellent prognosis, except angiomatosis, which can be locally aggressive and may recur. The main focus of this study is to present the radiographic, gross, and histopathologic characteristics of benign vascular lesions of the breast and their differential diagnoses.

Abstract
AIMS Anastomosing haemangioma is a rare benign vascular neoplasm that may histologically mimic angiosarcoma. We report the largest single institution series of anastomosing haemangioma in the adrenal gland with emphasis on clinical and radiological features. METHODS AND RESULTS Our laboratory information system was searched for a 25-year period (1999-2023), yielding seven cases confirmed as anastomosing haemangioma of the adrenal gland after pathological re-review. Clinical, radiological and pathological information was obtained from medical charts and submitting pathologists. Of a total of seven patients, four (57.1%) were men and three women, ranging in age from 37 to 75 years (mean = 61). Six of seven patients underwent adrenalectomies and one had radical nephrectomy. Tumours ranged from 0.7 to 6.4 cm (mean = 2.1 cm) and five of seven (71%) were grossly well-circumscribed. Five of seven lesions were found incidentally at imaging for other indications. All tumours were unifocal except one, which presented with multifocal disease with a concurrent adjacent retroperitoneal anastomosing haemangioma. Three of five tumours imaged with contrast enhancement were almost completely hyperenhancing with a small central non-enhancing portion, features overlapping with pheochromocytoma. One of seven tumours involved the peri-adrenal adipose tissue with a focally infiltrative pattern. There were no recurrences or metastases in six patients with available follow-up data (median = 95 months). CONCLUSIONS Benign anastomosing haemangiomas of the adrenal gland tend to occur in older patients, may mimic pheochromocytoma on imaging and must be distinguished from angiosarcoma pathologically. Better awareness of this entity by pathologists, radiologists and surgeons is crucial to appropriate work-up, diagnosis and management.

Abstract
Background Anastomotic hemangioma is a rare subtype of capillary hemangioma primarily found in the genitourinary tract. We present a case of a patient with an anastomotic hemangioma located in the retroperitoneal space; then, we explore and summarize the imaging features from previously reported cases for accurate diagnosis. Case presentation A 57-year-old woman complained of left lower back pain. Contrast-enhanced ultrasound revealed a hypoechoic mass with "slow-in and slow-out" enhancement. Abdominal CT scan displayed a well-defined, round soft tissue mass in the right retroperitoneal region with obvious enhancement. MRI indicated low signal on T1-weighted imaging, high signal on T2-weighted imaging and diffusion-weighted imaging, and progressive enhancement after enhancement. Surgical removal of the tumor was performed. Histopathological examination exhibited a distinct tumor border with interconnected blood vessels and a cavity lined by a single layer of cubic endothelial cells. Immunohistochemistry confirmed the presence of CD31[+] and CD34[+]. The final pathological diagnosis was anastomotic hemangioma. No recurrence was observed during a 40-month follow-up. Conclusion Retroperitoneal anastomotic hemangioma is a rare and benign neoplasm that may be misdiagnosed as ectopic pheochromocytoma or angiosarcoma. This case report presents and analyzes the imaging characteristics of a series of retroperitoneal anastomotic hemangiomas, which can be valuable for future diagnoses and help prevent unnecessary surgeries.

Abstract
Mesenchymal neoplasms of the liver can be diagnostically challenging, particularly on core needle biopsies. Here, I discuss recent updates in neoplasms that are specific to the liver (mesenchymal hamartoma, undifferentiated embryonal sarcoma, calcifying nested stromal-epithelial tumor), vascular tumors of the liver (anastomosing hemangioma, hepatic small vessel neoplasm, epithelioid hemangioendothelioma, angiosarcoma), and other tumor types that can occur primarily in the liver (PEComa/angiomyolipoma, inflammatory pseudotumor-like follicular dendritic cell sarcoma, EBV-associated smooth muscle tumor, inflammatory myofibroblastic tumor, malignant rhabdoid tumor). Lastly, I discuss metastatic sarcomas to the liver, as well as pitfalls presented by metastatic melanoma and sarcomatoid carcinoma.

Abstract
Anastomosing hemangioma is a recently described vascular neoplasm, initially identified in the male genitourinary tract. Since its first description, it has been reported at multiple anatomic sites, including rare cases in the female genital tract, most in the ovary. Herein we report the largest series to date of 12 ovarian anastomosing hemangiomas identified at our institution over a 15-yr period. The patients' age at the time of resection ranged from 50 to 76 yr (median: 62 yr), 3 patients presented with symptomatic pelvic masses, 3 tumors were identified by imaging studies, and the remaining 6 were incidentally discovered in ovaries removed for other indications. All tumors were unilateral, occurred at the ovarian hilum, and contained a vaguely lobulated architecture with sinusoidal-like vessels lined by hobnail endothelial cells with minimal to no cytologic atypia. A rim of luteinized/Leydig cells with abundant, eosinophilic cytoplasm and round, centrally placed nuclei surrounding the hemangioma was present in 9/12 tumors. Reinke crystals were observed in 3 of these 9 tumors. The volume of luteinized cells relative to the vascular proliferation ranged from 2% to 30%. All tumors with luteinized/Leydig cells also displayed numerous small eosinophilic, globular intracytoplasmic inclusions within the endothelial cells. The 3 tumors without luteinized/Leydig cells were exclusively intravascular lesions. Despite the frequent presence of luteinization/Leydig cells none of the patients experienced hormonal manifestations. Awareness of this rare benign ovarian entity is important, as its association with luteinized cells/Leydig cell hyperplasia (often exuberant) may be misinterpreted as a steroid cell tumor, Leydig-cell tumor, or as a mixed stromal-vascular tumor.

Myxoid Pseudotumor Involving the Renal Sinus: Clinicopathologic Study of 33 Cases Supporting a Distinct Benign Non-neoplastic Lesion. Am J Surg Pathol 2023; 47:218-223.

Abstract
We describe 33 cases of myxoid pseudotumor involving the renal sinus from 31 patients. Patients included 21 men and 10 women, ages 30 to 95 years. Twenty-seven cases (82%) had an associated malignancy, including urothelial carcinoma of the renal pelvis (22 cases), clear cell renal cell carcinoma (3 cases), urothelial carcinoma of the bladder (1 case), and poorly differentiated carcinoma of uncertain lineage (1 case). The remaining 6 (18%) had no associated malignancy and included 3 nephrectomies for ureteral stricture, 2 ureteropelvic junction repairs, and 1 resection of a "periureteral mass" (subsequently shown to be myxoid pseudotumor). Myxoid pseudotumor was identified by preoperative computed tomography imaging in 2 patients (6%) and identified by the gross dissector in 9 cases (27%). The mean size was 14 mm (range: 5 to 38 mm). All cases had an admixture of adipocytes, myxoid stromal matrix, variable collagenization, and a hypocellular population of bland spindled and stellate stromal cells. No multilobated atypical stromal cells were present. Clinical follow-up was available for 28 patients (90%), ranging from 1 to 132 months (mean: 24.6 mo). No patients had adverse events related to the myxoid pseudotumor. Myxoid pseudotumor of the renal sinus is often associated with a variety of adjacent neoplastic and non-neoplastic conditions and may present as a mass lesion detectable by imaging and/or gross inspection. Awareness of this benign process is important to avoid confusion with a neoplasm, especially liposarcoma.

Abstract
RATIONALE Female reproductive organ angiomas are rarely reported and are accidentally found during surgery. Angiomas arising from infundibulopelvic vessels presenting as adnexal masses are even rarer, and a few doctors have experience in their management. PATIENTS MAIN CONCERNS AND IMPORTANT CLINICAL FINDINGS Herein, we report the case of a 40-year-old woman who was admitted after a physical examination revealed an ovarian mass. The physical examination revealed a palpable adnexal mass in the right pelvic cavity. Ultrasound showed a 4.5 × 4.0 × 5.0 cm space-occupying lesion close to the right ovary, which had many echogenic lines and calcifications in its cystic cavity. PRIMARY DIAGNOSIS Right adnexal mass. INTERVENTIONS Laparoscopic surgery was performed in all the patients. During the surgery, the mass was found to be a retroperitoneal hemangioma with distorted and dilated vessels. We separated the right infundibulopelvic vessels and performed tumor resection with minimal blood loss. OUTCOMES The patient recovered well, and no abnormalities were observed during the following 2 years. Pathological results showed that this adnexal mass was a type of cavernous hemangioma arising from the infundibulopelvic vessels. LESSONS Surgical removal of the affected tissues is an aggressive treatment of choice for cavernous hemangiomas. Laparoscopic resection of infundibulopelvic hemangioma is feasible, and gynecologists are qualified for this operation, as long as damage to the iliac vessels is avoided.

Abstract
Introduction Anastomosing hemangioma in the adrenal area is extremely rare. We report a large anastomosing hemangioma in the adrenal area that underwent robot‐assisted adrenalectomy. Case presentation A 49‐year‐old man with left back pain underwent magnetic resonance imaging (MRI) that revealed a tumor in the left adrenal area; it was diagnosed as nonfunctional endocrinologically. However, the major axis of the tumor increased from 64 to 72 mm during the 4‐month period. Robot‐assisted left adrenalectomy was performed. Although the large tumor adhered to the surrounding tissues, it was safely resected by the effective use of an extra robotic arm. An anastomosing hemangioma was diagnosed since there were no malignant findings. Conclusion Robotic surgical systems may serve as an effective treatment option for large adrenal tumors, and our report is the first robot‐assisted adrenalectomy performed on an anastomosing hemangioma.

Abstract
Anastomosing haemangioma (AH) is a newly described distinct vascular neoplasm that histologically may confuse with well-differentiated angiosarcoma (AS) for those who are unfamiliar with this rare entity. We aimed to identify molecular genetic differences between AHs and ASs by carrying out immunohistochemistry (IHC), fluorescence in situ hybridization (FISH), and next-generation sequencing (NGS). Immunohistochemically, all six cases showed positivity for cyclinD1 and pERK. All cases of AH showed focal weak positive reaction for p53 and MIB-1, and the IHCs for HIF-1α were all negative for all three cases. Those three cases of angiosarcoma revealed strong, diffuse positivity for p53, 50%–70% MIB-1 labelling, and multifocal, moderate to strong HIF-1α expression. To further clarify the difference in p53 expression, we carried out a FISH which revealed 17p polysomy in all three ASs whereas copy number aberration was absent in the AH group. In one AH case, the GNA11 c.627G > T nucleotide variant was detected. Due to the rarity and overlapping morphological features, AH might be difficult to separate from other vascular tumours, in particular from well-differentiated AS also featured by mild hyperchromatic, hobnail-like endothelial cells. The potential molecular differences between these two entities presented here may be used in support of the correct diagnosis.

Abstract
Background Anastomosing hemangioma (AH) is a rare vascular tumor and occurs in various organs. It is difficult to distinguish AH from malignant tumors even through multimodal imaging examination. AH located in the inguinal region is even rare. We present the diagnosis and treatment of a patient with spermatic cord AH in detail and conduct a literature review. Case Report An 84-year-old Chinese man had swelling pain in his right scrotum. A hard and fixed mass was palpable in the right inguinal region. Preoperative radiological examination considered it a neurogenic or vascular tumor. Malignant soft tissue sarcoma could not be excluded. He underwent radical inguinal right orchiectomy under intraspinal anesthesia. The diagnosis of spermatic cord AH was confirmed by pathological examination. The patient recovered uneventfully and remained disease-free during an 18-month follow-up. Conclusion Spermatic cord AH is quite rare and could be misdiagnosed as a malignant tumor. Pathological evidence might be necessary. The optimal choice of treatment should be determined through a comprehensive assessment of both tumor and patient factors.

Abstract
PURPOSE OF REVIEW The advances of molecular techniques have led to the refinement of the classification of mesenchymal tumors, leading to newly introduced entities in the recently published fifth edition of the WHO Classification of Soft Tissue and Bone Tumors, which are discussed in this review. RECENT FINDINGS For the first time, entities are included of which the name refers to the underlying molecular alteration including round cell sarcoma with EWSR1 -non-ETS fusions, CIC -rearranged sarcoma, and sarcoma with BCOR genetic alteration. EWSR1-SMAD3 -positive fibroblastic tumor and NTRK -rearranged spindle cell neoplasm are provisionally included as 'emerging' entities based on the underlying molecular alteration, though the entity still needs to be better defined. Other newly recognized entities are not named after their molecular change, but the molecular alteration helped to delineate them from others: atypical spindle cell/pleomorphic lipomatous tumor, anastomosing hemangioma, angiofibroma of soft tissue, myxoid pleomorphic liposarcoma, and poorly differentiated chordoma. SUMMARY Classification of mesenchymal tumors is increasingly based on the underlying molecular changes, although this cannot be interpreted separately from clinical, morphological, and immunohistochemical characteristics.

Abstract
Anastomosing hemangioma (AH) is a rare, benign vascular neoplasm with distinctive histopathology and characteristic tumor distribution. AHs show marked proclivity to involve the kidneys, gonads and the retroperitoneal soft tissues; kidney is the most common target site often in the context of end stage renal disease. Recent studies have identified activating mutations of GNA genes that drive the molecular pathogenesis of AHs. AH appears as a solitary, well-circumscribed, hypervascular tumor that charters a benign course with an excellent prognosis. The purpose of this article is to provide a current update on clinical, pathological and imaging features of anastomotic hemangioma.

Abstract
Background Anastomosing hemangioma is an uncommon benign vascular tumor that may be mistaken for a malignancy. The imaging findings of anastomosing hemangioma are not well provided from the previous reports. Herein, in the study, we discuss the imaging findings for one case of retroperitoneal anastomosing hemangioma. Case presentation One 64-year-old female patient had a left retroperitoneal mass that was incidentally detected upon physical examination. A hypoechoic mass with abundant blood flow signals was found by US in the perirenal space. CT and MRI detected a large cystic and solid lesion in the left retroperitoneal space. Plain CT indicated that the internal density was uneven, and the pattern of enhancement was obvious and progressive. MRI-T2WI showed high intensity, DWI showed isointensity, and the mass also showed obvious progressive enhancement. Finally, anastomosing hemangioma was diagnosed via histopathological studies. Conclusion As a rare and benign tumour, anastomosing hemangioma is easily misinterpreted. We suggest that the observation of “genitourinary tract related, well defined, hyperintensity or isointensity on T2WI, isointensity on DWI, and obvious progressive enhancement patterns likely to the vascular enhancement” may consider the diagnosis of AH.

Abstract
Primary vascular tumours of the kidney are rare and may pose diagnostic difficulties because of their similar clinical, morphological, and immunohistochemical features. This article summarizes the clinical and pathological features of primary renal angiosarcoma and anastomosing haemangioma of the kidney including epidemiology, genetics, and prognosis. Renal anastomosing haemangiomas are benign neoplasms characterized by anastomosing capillary-sized vascular channels. These tumours are rare, with about 75 cases reported in the literature. Most anastomosing haemangiomas are found incidentally on ultrasound, computed tomography, or magnetic resonance imaging. Common symptoms include abdominal pain, haematuria, and abdominal mass. Renal anastomosing haemangiomas are characterized by recurrent mutations in GNAQ and GNA14 genes. The prognosis of anastomosing haemangioma is excellent. Primary renal angiosarcomas are malignant tumours showing endothelial differentiation. To date, 76 cases have been described in the literature. Primary renal angiosarcomas are frequently symptomatic. The clinical features of renal angiosarcomas are similar to those of renal anastomosing haemangiomas, including abdominal pain, haematuria, and abdominal mass. Angiogenesis-related genes and vascular-specific receptor tyrosine kinases such as KDR, TIE1, SNRK, TEK, and FLT1 are upregulated in angiosarcomas. Primary renal angiosarcomas are highly aggressive neoplasms with a poor prognosis despite surgical treatment, chemotherapy, radiotherapy, or targeted therapy.

Abstract
In this article, the authors have reviewed all the recent news regarding how the discovery of some novel and recurrent molecular and genetic changes has modified the classification of some entities and have addressed to the description of new variants of vascular tumors. And even more important, the authors also reviewed on how these findings, in addition to gain insight into the tumoral biology, portend significant clinical consequences not only regarding to their diagnosis but also to their management and prognosis because some of these mutations are potential targets for treatment. The authors have also highlighted immunohistochemical markers can help us as a surrogate marker of those molecular alterations.

Abstract
Background Although anastomosing hemangiomas are very rare and benign vascular neoplasms, these tumors are more common among patients with end-stage kidney disease. Incidental finding of these tumors in the kidney or adrenal gland has been reported. Herein, we describe a case in which an anastomosing hemangioma was misdiagnosed as a renal cell carcinoma before kidney transplant. Case presentation A 35-year-old woman with lupus nephritis was admitted to our emergency department for suspected uremic symptoms of nausea and general weakness. She had received hemodialysis due to end-stage kidney disease, and a living-donor kidney transplantation from her father was planned. On pre-operative contrast-enhanced computed tomography and magnetic resonance imaging, a 1.7 cm renal cell carcinoma was observed in the right kidney. On staining after radical nephrectomy, irregularly shaped vascular spaces of various sizes were observed, with these spaces having an anastomosing pattern. As the findings of the anastomosing hemangioma are similar to those of a renal cell carcinoma on imaging, histology examination was necessary to confirm the diagnosis of anastomosing hemangioma and to prevent delay in listing for kidney transplantation. Good kidney function was achieved after transplantation, with no tumor recurrence. Conclusion Our case underlines the importance for prompt surgical resection of an enhancing renal mass to confirm diagnosis in patients scheduled for kidney transplantation to avoid any delay.

Abstract
Anastomosing hemangioma (AH) are rare mesenchymal neoplasms affecting kidney with about 50 cases reported in English literature. In general, they are accidentally detected during examination or imaging done for nonspecific symptoms or wellness check-up. There are no key diagnostic features on the imaging modalities. The most common preoperative diagnosis has been a malignant primary renal carcinoma. Surgical resection remains the mainstay of treatment and of choice in symptomatic lesions. We are presenting a rare case of giant AH of the kidney mimicking a renal cell carcinoma on imaging. The lesions are characterized by anastomosing sinusoidal-like vascular spaces lined by banal endothelial cells with occasional hobnail morphology and associated with extramedullary hematopoiesis. The treatment of choice could be a conservative approach in small and asymptomatic lesions and patients with pre-existing renal dysfunction; hence, this entity should be in the differential of vascular renal neoplasms considering its proclivity to the urogenital tract. This is the first case in Indian literature to the best of our knowledge.

Abstract
The fifth edition of the World Health Organization (WHO) classification of soft tissue and bone tumours was published in May 2020. This 'Blue Book', which is also available digitally for the first time, incorporates an array of new information on these tumours, amassed in the 7 years since the previous edition. Major advances in molecular characterisation have driven further refinements in classification and the development of ancillary diagnostic tests, and have improved our understanding of disease pathogenesis. Several new entities are also included. This review summarises the main changes introduced in the 2020 WHO classification for each subcategory of soft tissue and bone tumours.

Abstract
Anastomosing haemangioma is a rare benign vascular neoplasm, which may mimic angiosarcoma histologically. We here present a case of anastomosing haemangioma arising from the kidney. This patient presented with a large kidney mass and adrenal mass. The clinical and radiological findings were suspicious for renal cell carcinoma with metastasis. Radical nephrectomy and adrenalectomy were thus performed. Histopathological examination and immunohistochemical studies concluded a diagnosis of anastomosing haemangioma of the kidney and concurrent adrenal cortical adenoma. It is important to differentiate this tumor from other borderline or malignant vascular neoplasms.

Abstract
During the last two decades, there have been significant strides in the diagnosis of soft tissue tumors, including identification of various tumor entities, newer immunohistochemical markers, and an increasing number of molecular signatures, defining certain tumors. Lately, there are certain emerging tumor entities, defined by their molecular features with an impact on treatment. At the same time, there is a certain degree of overlap in the expression of certain immunohistochemical antibody markers, as well as genetic markers, with certain gene rearrangements and chimeric fusions observed among completely different tumors. Moreover, a certain amount of clinicopathological, immunohistochemical, and molecular proximity has been unraveled among certain tumor types. Over the years, the World Health Organization (WHO) fascicles on tumors of soft tissue have succinctly brought out these aspects. The present review describes recent updates in the diagnosis of soft tissue tumors, including certain newly described tumor entities; emphasizing upon newer, specific immunohistochemical and molecular markers, along with concepts, regarding "intertumor relationships".

Abstract
Soft tissue tumors are a relatively rare and diagnostically challenging group of neoplasms that can have varying lines of differentiation. Accurate diagnosis is important for appropriate treatment and prognostication. In the 8 years since the publication of the 4th Edition of World Health Organization (WHO) classification of soft tissue tumors, significant advances have been made in our understanding of soft tissue tumor molecular biology and diagnostic criteria. The 5th Edition of the 2020 WHO classification of tumors of soft tissue and bone incorporated these changes. Classification of tumors, in general, but particularly in soft tissue tumors, is increasingly based on the molecular characteristics of tumor types. Understanding tumor molecular genetics improves diagnostic accuracy for tumors that have been difficult to classify on the basis of morphology alone, or that have overlapping morphologic features. In many large hospitals in the United States and Europe, molecular tests on soft tissue tumors are a routine part of diagnosis. Therefore, surgical pathologists should be familiar with newly emerging molecular genetic techniques in clinical settings. In the near future, molecular tests, particularly in soft tissue tumor diagnosis, will become as routine during diagnosis as immunohistochemistry is currently. This new edition provides an updated classification scheme and essential diagnostic criteria for soft tissue tumors. Newly recognized entities and subtypes of existing tumor types, several reclassified tumors, and newly defined molecular and genetic data have been incorporated. Herein, we summarize the updates in the WHO 5th Edition, focusing on major changes in each category of soft tissue tumor, and the newly described tumor entities and subtypes.

Abstract
Mesenchymal tumours represent one of the most challenging field of diagnostic pathology and refinement of classification schemes plays a key role in improving the quality of pathologic diagnosis and, as a consequence, of therapeutic options. The recent publication of the new WHO classification of Soft Tissue Tumours and Bone represents a major step toward improved standardization of diagnosis. Importantly, the 2020 WHO classification has been opened to expert clinicians that have further contributed to underline the key value of pathologic diagnosis as a rationale for proper treatment. Several relevant advances have been introduced. In the attempt to improve the prediction of clinical behaviour of solitary fibrous tumour, a risk assessment scheme has been implemented. NTRK-rearranged soft tissue tumours are now listed as an "emerging entity" also in consideration of the recent therapeutic developments in terms of NTRK inhibition. This decision has been source of a passionate debate regarding the definition of "tumour entity" as well as the consequences of a "pathology agnostic" approach to precision oncology. In consideration of their distinct clinicopathologic features, undifferentiated round cell sarcomas are now kept separate from Ewing sarcoma and subclassified, according to the underlying gene rearrangements, into three main subgroups (CIC, BCLR and not ETS fused sarcomas) Importantly, In order to avoid potential confusion, tumour entities such as gastrointestinal stroma tumours are addressed homogenously across the different WHO fascicles. Pathologic diagnosis represents the integration of morphologic, immunohistochemical and molecular characteristics and is a key element of clinical decision making. The WHO classification is as a key instrument to promote multidisciplinarity, stimulating pathologists, geneticists and clinicians to join efforts aimed to translate novel pathologic findings into more effective treatments.

Abstract
BACKGROUND Anastomosing hemangioma (AH) is a rare subtype of benign hemangioma that is most commonly found in the genitourinary tract. Due to the lack of specific clinical and radiologic manifestations, it is easily misdiagnosed preoperatively. Here, we report a case of AH arising from the left renal vein that was discovered incidentally and confirmed pathologically, and then describe its imaging characteristics from a radiologic point of view and review its clinicopathologic features and treatment.
CASE SUMMARY A 74-year-old woman was admitted to our department for a left retroperitoneal neoplasm measuring 2.6 cm × 2.0 cm. Her laboratory data showed no significant abnormalities. A non-contrast-enhanced computed tomography (CT) scan showed a heterogeneous density in the neoplasm. Non-contrast-enhanced magnetic resonance imaging (MRI) revealed a heterogeneous hypointensity on T1-weighed images and a heterogeneous hyperintensity on T2-weighed images. On contrast-enhanced CT and MRI scans, the neoplasm presented marked septal enhancement in the arterial phase and persistent enhancement in the portal phase, and its boundary with the left renal vein was ill-defined. Based on these clinical and radiological manifestations, the neoplasm was initially considered to be a neurogenic neoplasm in the left retroperitoneum. Finally, the neoplasm was completely resected and pathologically diagnosed as AH.
CONCLUSION AH is an uncommon benign hemangioma. Preoperative misdiagnoses are common not only because of a lack of specific clinical and radiologic manifestations but also because clinicians lack vigilance and diagnostic experience in identifying AH. AH is not exclusive to the urogenital parenchyma. We report the first case of this neoplasm in the left renal vein. Recognition of this entity in the left renal vein can be helpful in its diagnosis and distinction from other neoplasms.

Abstract
Anastomosing hemangioma of the ovary is a benign neoplasm. It may present with features similar to invasive ovarian carcinoma. Radiology, pathology, and clinical correlation are important for diagnosis.
Anastomosing hemangioma (AH) is an uncommon benign vascular tumor reported to occur in the kidney and, in rare instances, the ovary. While most cases of AH in the ovary are incidental findings, we report a case of ovarian AH presenting with abdominal ascites and elevated CA-125 suggestive of metastatic ovarian cancer. Postoperative histopathologic examination demonstrated a tumor consisting of numerous vascular spaces lined by benign-appearing endothelial cells with exuberant hilus cell hyperplasia. These characteristics led to the diagnosis of anastomosing hemangioma of the ovary. A summary of the characteristics of AH, along with a review of all previously reported cases and possible theories for its presentation, are discussed.

Abstract
Background Cavernous hemangioma, as a rare tumor, is difficult to differentiate from retroperitoneal lymphoma and paraganglioma. They are more difficult to excise completely through open surgery and traditional laparoscopic surgery. The study aimed to evaluate the role of DaVinci surgical system in laparoscopic resection of parapelvic cavernous hemangioma. Case presentation A 46-year-old female, who diagnosed as parapelvic cavernous hemangioma accompanying with thrombosis and calcification, was performed laparoscopic resection using DaVinci surgical system under general anesthesia. The patient well recovered without recurrence or spread of the lesion after operation for 3 months as well as hydronephrosis was significantly relieved. Conclusion Laparoscopic resection of parapelvic cavernous hemangioma under the help of DaVinci surgical system was feasible and safe.

Abstract
AIMS Congenital haemangiomas (CHs) can be subdivided into different subtypes [rapidly involuting CHs (RICHs), non-involuting CHs (NICHs), and partially involuting CHs (PICHs)]. During the first few days of life, RICHs may be associated with transient but sometimes marked thrombocytopenia. We sought to assess the histological aspects and clinicopathological correlations of the three subtypes. METHODS AND RESULTS We assessed the histopathological features of 10 RICHs, 25 NICHs, and 20 PICHs, described the patients' long-term clinical outcomes, and assessed clinicopathological correlations. All CHs were located in the dermis and hypodermis, and comprised both capillary lobules (with three distinct histopathological patterns) and extralobular large vessels. Most of the extralobular vessels were abnormal veins and abnormal lymphatic vessels. We did not observe significant correlations between the CH subtype, the histopathological pattern, and the time of the histopathological assessment. Interestingly, unexpected intralobular expression of podoplanin was found in neonatal biopsies of five RICHs and PICHs. Four of these five patients had concomitant thrombocytopenia. The podoplanin staining intensity decreased over time as the thrombocytopenia resolved and the tumour shrank. CONCLUSION The histopathological features were similar in all three subtypes of CH, and were related to the time since disease onset; we consider that RICH, PICH and NICH form a single entity and differ only in their involuting potential. Along with the transient expression of intralobular podoplanin observed in some specimens from the newborn, the lobular architecture might lead to misdiagnosis of tufted haemangioma or kaposiform haemangioendothelioma.

Abstract
OBJECTIVE Anastomosing hemangioma (AH) is a novel tumor of vascular origin. Though well-documented in the kidney and retroperitoneum, only a single case has been documented in the head and neck, and AH in larynx has not been described. METHODS A 37-year-old male presented with difficulty in breathing, and hoarseness. Imaging revealed a lesion involving left paraglottic and cricothyroid spaces with destruction of cricoid cartilage, suggestive of a malignant cartilageneous neoplasm. Multiple biopsies were non-diagnostic. RESULTS Intraoperative frozen section during transcervical resection showed a vascular tumor devoid of nuclear atypia. Histopathological examination revealed a vasoformative tumor comprised of anastomosing capillary-sized vessels lined by flat and hobnail endothelial cells, consistent with AH. The patient was disease-free at 12 months. CONCLUSION AH are rare neoplasms that may mimic a malignancy on imaging, especially in sites where they have not been documented. Due to their vascular nature, biopsies are often non-diagnostic, making preoperative diagnosis difficult. Frozen section may assist in decision-making on the extent of resection required.

Abstract
Anastomosing hemangioma (AH) is an unusual benign vascular lesion that commonly occurs in the kidney and genitourinary tract. We report a case of AH in a 49-year-old woman presenting as a mass in the breast, a site which, to the best of our knowledge, has not been previously documented in the English literature. Microscopic examination of the mass revealed a well-demarcated proliferation of anastomosing vascular spaces lined by bland endothelial cells, with focal hobnailing and scattered intravascular fibrin thrombi. No mitotic activity was observed and the Ki-67 proliferative index was low. These features were interpreted as AH, a lesion that may be difficult to distinguish from low-grade angiosarcoma or other benign vascular lesions of the breast which may demonstrate anastomosing channels. Due to the presence of atypical histologic features which can raise suspicion for angiosarcoma on biopsy, complete excision of these lesions is recommended for optimal treatment.

Abstract
An anastomosing hemangioma is a relatively new diagnosis of a benign vascular lesion that is typically found in the genitourinary tract. On imaging, anastomosing hemangiomas have a broad differential diagnosis and can resemble malignant lesions such as angiosarcoma. Here we present a case of a 33-year-old male with seizures who on imaging was found to have a presumed recurrent intracranial meningioma. After surgical resection of his lesion, this case was pathologically diagnosed as having anastomosing hemangioma. To our knowledge, this is the first report of a case of a thrombosed anastomosing hemangioma located at intracranial and intradural region.

Abstract
Anastomosing hemangiomas are rare variants of vascular tumors found in adrenal, hepatic, and gastrointestinal tissue. Frequently, renal anastomosing hemangiomas are misdiagnosed on computed tomography (CT) as kidney cancers, resulting in unnecessary workups and detrimental treatments. We present a rare case of bilateral renal and adrenal anastomosing hemangioma found incidentally on renal biopsy. Patient is a 39 year-old African American male on hemodialysis with a history of end-stage renal disease secondary to lupus who presented with acute pericarditis and worsening renal insufficiency.

Thrombotic Hemangioma With Organizing/Anastomosing Features: Expanding the Spectrum of GNA-mutated Hemangiomas With a Predilection for the Skin of the Lower Abdominal Regions. Am J Surg Pathol 2019; 44:255-262.

Abstract
In this study, we aimed to present the clinicopathologic and molecular features of a distinct group of hemangioma with GNA mutations that exhibited prominent thrombosis and organization changes with florid intravascular endothelial cell proliferation that we provisionally termed "thrombotic hemangioma with organizing/anastomosing features." Twenty-six cases were included. No sex predilection was seen (male:female=13:13). Patients' age ranged from 17 to 89 years (median: 51 y). All but 1 occurred in the skin whereas the remaining tumor involved the neck soft tissue. Remarkably, the majority (18) occurred in the lower abdominal/inguinal regions. Histologically, thrombotic hemangioma with organizing/anastomosing features were circumscribed tumors composed of variably sized and congested thin-walled vessels. The most striking features were prominent thrombosis and organization with florid intravascular endothelial cell proliferation. The proliferating endothelial cells exhibit a streaming pattern with focal anastomosing-like feature resembling anastomosing hemangioma. The stroma was sclerotic or hyalinized but could also be myxoid/edematous. Other features included vessels with nuclear hobnailing and perivascular hyalinization, cherry hemangioma-like component, cavernous-like or sinusoidal hemangioma-like areas, Masson hemangioma-like feature, and spindle cell fascicular pattern. Mitotic activity was usually low and nuclei were bland but 2 tumors exhibited moderate nuclear atypia and higher mitotic activity. Extramedullary hematopoiesis and hyaline globules were not identified. Genetically, by Sanger sequencing and MassARRAY analysis, mutually exclusive GNAQ, GNA11, and GNA14 exon 5 mutations were identified in 15, 5, and 2 tumors, respectively, with a combined mutation rate of 85% (22/26). In conclusion, we described a distinct group of hemangioma and expanded the clinicopathologic features of GNA-mutated hemangiomas.
