Abstract
A 69-year-old male patient presented with multiple lung nodules revealed by chest-computed tomography (CT) during a preoperative examination for an appendiceal tumor. The nodule diameters ranged from 2-10 mm without either pleural thickening or effusions. A fluorine-18-labeled fluorodeoxyglucose (18F-FDG)-positron emission tomography (PET)/CT scan showed a high FDG uptake in the appendiceal tumor, but almost normal standardized uptake values in the bilateral lung nodules. A CT-guided biopsy led to a diagnosis of pulmonary epithelioid hemangioendothelioma, a rare vascular tumor with a radiological presentation similar to that of a metastatic lung tumor. The present case is the first to describe successful treatment using a CT-guided biopsy instead of more conventional methods.

Abstract
Epithelioid hemangioendothelioma (EHE) is a rare neoplasm of vascular origin that can arise in multiple and varied tissue sites. Pleural epithelioid hemangioendothelioma (PEH), a subtype of EHE, is particularly less reported. Herein, we describe a case of PEH presented with left-sided back pain in a 68-year-old female, and her chest CT scan revealed thickening of the left pleura and left pleural effusion, the histological diagnosis was confirmed by both conventional examination and immunohistochemistry. A literature search utilizing PubMed, Embase, Ovid and Cochrane, Wanfang and Chinese National Knowledge infrastructure (CNKI) for PEH was conducted to investigate the characteristics of the disease, 26 related articles were retrieved and 40 cases of PEH were reported. According to available literature, the average age at presentation is 51.8 years and the disease occurred more often in men than women. The etiology of the disease remained unknown. Chest pain, cough, and dyspnea were the common symptoms. Computed tomography usually revealed pleural effusion and pleural thickening. Histological examinations revealed mainly epithelioid cells. Immunohistochemical stains were positive for vascular endothelial markers. PEH tends to have more aggressive behavior than tumors in other locations, thus effective treatment has not yet been established until now. Further studies are needed to analyze the prognostic factors, clinical features and treatment of PEH.

Abstract
Hemangioendotelioma is a group of rare vascular tumors with border-line behavior. They may involve internal organs, limbs, bones and soft tissue. The histological variant epitheliod hemangiothelioma is locally aggressive and has metastatic potential. We present a case of a 41-years old woman affected by epitheliod hemangiothelioma of the right quadriceps. The patient complained of localized pain in the anterior region of the right thigh, which started about 3 months earlier during physical exercise. For the increasing size of the lesion, the patient was referred to our Department. On physical examination, the lesion appeared elastic, fixed to the surrounding tissues and painful under pressure. An ultrasound examination revealed a small avascular lesion and a MRI examination showed an oval formation measuring about 18 mm in diameter of nonspecific significance. A surgical removal of the lesion was performed and diagnosis of epithelioid hemangiothelioma was achieved. A complete removal of the quadriceps muscle was then accomplished. In this paper, clinical and oncologic aspects of this rare tumor are discussed KEY WORDS: Epithelioid hemangiothelioma, Lower limbs tumor, Rare tumors.

Abstract
RATIONALE Epithelioid angiosarcoma (EA) is a rare, highly invasive tumor. The histopathological features of EA are not distinct and less reported in the literature, and most of the medical records are incomplete. PATIENT CONCERNS A 61-year-old woman who came to the hospital because of pain in her right hip. This patient had had surgery for right hip tuberculosis 30 years ago. DIAGNOSES The present study reports a case of primary EA of bone with aneurysmal bone cyst (ABC) that was diagnosed by 3 experienced pathologists. INTERVENTIONS The patients had undergone 2 surgeries; however, an early recurrence of the tumor was caused the death of the patient. OUTCOMES Ten EA cases from other literature were reviewed in this article; all the symptoms were found in different parts of bone, and the case data were relatively complete. The primary clinical features and nonspecific histopathological morphology of the disease were summarized from the 11 cases mentioned in the literature, and the main immunohistochemistry characteristics and diagnostic traps of EA were reviewed. LESSONS Because the tumor has no characteristic diagnostic index in imaging and laboratory examination, the histopathologic features are not typical, especially in the case of obvious secondary lesions. It is easy to miss and misdiagnose. If possible, the diagnosis should be combined with immunohistochemical results.

Abstract
RATIONALE Primary gastric epithelioid angiosarcoma is a highly aggressive endothelial cell malignancy and may pose a great diagnostic challenge. PATIENT CONCERNS Here we describe the case of a 56-year-old man presented with melena and epigastric dull pain for 2 weeks. DIAGNOSIS Primary gastric epithelioid angiosarcomas: the definitive diagnosis was provided by immunohistochemical analysis with endothelial markers such as cluster of differentiation 31 (CD31), ether-a-go-go-related gene (ERG), and Freund leukemia integration (FLI-1). INTERVENTIONS After gastroscopic biopsy was performed at the bleeding fundus and the results suggested malignant tumor, radical gastrectomy was performed. OUTCOMES Unfortunately, regional lymph node enlargement and distant metastases occurred about 1 month later. The patient did not have the opportunity to undergo chemotherapy or other treatment and died from multiple organ dysfunction syndrome. LESSONS Primary gastric epithelioid angiosarcomas are rare tumors with a high rate of lymph nodes and peripheral organs metastasis. The strong cytokeratin expression in epithelioid angiosarcomas represents a diagnostic pitfall for pathologists. Their clinical behaviors are unpredictable and results with surgical excision alone have been disappointing. Thus, the prognosis is generally considered poor and patients seldom can survive over 1 year after diagnosis.

Abstract
RATIONALE Intravascular epithelioid hemangioendothelioma (EHE) is a rare endothelial tumor with an intermediate grade of malignancy. We present a case of one woman affected by EHE of the femoral vein. Contrast-enhanced ultrasonography played a role in diagnosing EHE and helped differentiate it from thrombosis. To our knowledge, this is the first reported contrast-enhanced ultrasonography of intravascular EHE in the imaging literature. PATIENT CONCERNS A 46-year-old woman presented to our hospital due to pain and swelling in her right lower limb since 5 years prior to her presentation. DIAGNOSES The patient was misdiagnosed as having thrombosis by ultrasound. Contrast-enhanced ultrasonography showed solid lesions with visible blood supply, suggesting angiogenic tumors. INTERVENTIONS The patient was treated by complete surgical removal of the mass and postoperative radiotherapy. Pathological examination confirmed the diagnosis of EHE. OUTCOMES During follow-up, there were no signs of local or distant relapse. LESSONS Intravenous EHE may be misdiagnosed as thrombosis by ultrasound and contrast-enhanced ultrasonography can help make the differential diagnosis.

Abstract
Epithelioid hemangioendothelioma (EHE) is a rare indolent vascular tumor which occurs at liver, lung, bone, and so on. However, the etiology of EHE is evasive.These patients were enrolled at the First Affiliated Hospital of Xi'an Jiaotong University from January 2011 to December 2015. Retrospective analysis is done by demographic data of clinical manifestations, laboratory parameters, CT imaging, histological, and immunohistochemical features in 9 cases in Shaanxi.Of the patients, 8 were females (88.9%) and 1 were males (11.1%). The age ranged from 34 to 71 years (mean 49 years; median 49 years). Anatomical sites of primary lesions were as follows: liver (n = 6, 66.7%), upper extremities (n = 1, 11.1%), sublingual gland (n = 1, 11.1%), and spine (n = 1, 11.1%). Metastatic disease was diagnosed in 5 cases (55.6%) with occurrence in lung (n = 4, 44.4%), bone (n = 2, 22.2%), upper extremities (n = 1, 11.1%), pleura (n = 1, 11.1%), and spleen (n = 1, 11.1%). Tumor size ranged from 0.5 to 6.8 cm (mean 3 cm). The most tumors were composed of highly cellular areas with small and prominent nucleoli in vesicular nuclei, and ERG (100%) was the most frequently positive in these cases, followed by CD31 (88.9%) and CD34 (77.8%) via histology and immunohistochemistry techniques.EHE is a very rare in Shaanxi. It is significant to find its clinical, radiological, and pathological characters, helping for EHE early diagnosis and treatment, reducing misdiagnosis and improving life quality.

Abstract
RATIONAL Epithelioid hemangioendothelioma (EHE) is a rare neoplasm commonly known to arise from the soft tissue, lung, and liver. EHE arising from right innominate vein (RIV) has scarcely been reported in English literature. PATIENT CONCERNS Herein, we present a rare case of EHE of RIV in a 51-year-old woman with right-lower chest pain for 4 days. Computed tomography of the chest revealed a spherical mass with calcification and fatty foci located in the anterior mediastinum, thus a presumptive diagnosis of teratoma was made. DIAGNOSES, INTERVENTIONS, AND OUTCOMES Video-assisted thoracoscopic explorations and resection of mediastinal tumor were then performed. The pathological examination showed that the tumor was EHE. Postoperative radiotherapy was delivered to the patient. Pulmonary metastases were found by chest CT a year after surgery. LESSONS A diagnosis of EHE might be considered, when a mediastinal tumor closely related to veins showing intratumoral calcification and obvious enhancement, despite the presence of a clear boundary and visible fat content.

Abstract
BACKGROUND Hepatic epithelioid hemangioendothelioma (HEHE) is a rare vascular tumor which has an intermediate aggressive behavior. Although the value of liver transplantation (LT) is well established, its place in the management of HEHE is still unclear. The aim of this study is to confirm, based on a very large patient cohort, the value of LT in the management of HEHE and to identify risk factors for post-LT recurrence. METHODS The outcome of 149 transplant recipients with HEHE recorded in the European Liver Transplant Registry during the period November 1984 to May 2014 was analyzed. Median post-LT follow-up was 7.6 years (interquartile range, 2.8-14.4). RESULTS Cox regression analysis showed that macrovascular invasion (hazard ratio [HR], 4.8; P < 0.001), pre-LT waiting time of 120 days or less (HR, 2.6; P = 0.01) and hilar lymph node invasion (HR = 2.2; P = 0.03), but not pre-LT extrahepatic disease, were significant risk factors for recurrence. These findings, which were also confirmed in a propensity score analysis, allowed the development of a HEHE-LT score enabling stratification of patients in relation to their risk of tumor recurrence. Patients with a score of 2 or less had a much better 5-year disease-free survival compared to those having a score of 6 or higher (93.9% vs 38.5%; P < 0.001). CONCLUSIONS The analysis of this (largest in the world) HEHE adult liver recipient cohort clearly confirms the value of LT in the treatment of this rare disorder and also permits identification of patients at risk of posttransplant recurrence. Posttransplant follow-up should take the HEHE-LT score into account. Extrahepatic disease localization is reconfirmed not to be a contraindication for LT.

Abstract
Hepatic epithelioid hemangioendothelioma (HEH) is a rare tumor of vascular endothelial origin. Spontaneous rupture of HEH is a life-threatening complication and is extremely rare. HEH has variable malignant potential, and the clinical diagnosis remains challenging. Here we report a case of HEH with spontaneous rupture. A 44-year-old man presented with constant cutting pains over the right upper abdomen after eating. He had hemoptysis 11 d previously. Diagnostic abdominal puncture demonstrated active bleeding. Chest and abdominal computer tomography scan showed multiple ground-glass nodules over the lungs, multiple low-density intrahepatic nodules and massive hemorrhage. Transcatheter arterial embolization and exploratory laparotomy were performed and subsequent immunohistochemical examination confirmed a diagnosis of HEH.

Abstract
Hepatic epithelioid hemangioendothelioma (HEHE) is a rare category of vascular tumor with uncertain malignant potential. It commonly presents nonspecific and variable clinical manifestations, ranging from asymptomatic to hepatic failure. In addition, laboratory measurements and imaging features also lack specificity in the diagnosis of HEHE. The aim of the present study is to highlight the dilemma and challenges in the preoperative diagnosis of HEHE, and to enhance awareness of the range of hepatobiliary surgery available in patients with multiple hepatic nodular lesions on imaging. In these patients, HEHE should at least be considered in the differential diagnosis.

Abstract
The case of a 15-year-old boy with a severe swelling of the 2nd toe in the left foot and a large swelling of the left inguinofemoral region is described. Histologic examination of the foot lesion showed a typical epithelioid hemangioma of bone that extended into the soft tissues, with a secondary location in the groin, suggestive of lymph node involvement. Subsequently, imaging also revealed swelling of iliac and para-aortic lymph nodes, which probably indicates further lymph node spread.. Besides the fact that epithelioid hemangioma of the toe has not been reported yet, our case showed a noncontinuous localization, most likely in draining lymph nodes. This finding suggests metastatic disease, an event that is extremely rare for epithelioid hemangioma. As such, epithelioid hemangioma might be comparable to another benign vascular tumor, the retiform hemangioendothelioma, which occasionally metastasizes to the lymph nodes without systemic spread.

Abstract
PURPOSE To evaluate imaging findings of hepatic epithelioid hemangioendothelioma (HEH), with emphasis on solitary form at the initial presentation. MATERIALS AND METHODS Ten cases of pathologically confirmed HEH were retrospectively reviewed; seven patients had CT and MR images and three had only CT images. Two radiologists assessed the followings in consensus: lesion number, size, location, presence of capsular retraction and calcification, attenuation, signal intensity, and enhancement pattern. RESULTS Initially, HEHs manifested as a single mass (n = 5) or multiple masses (n = 5). One case demonstrated a solitary nodule at first, which subsequently transformed to multifocal nodules on serial follow-up. The maximal diameter of the lesions ranged from 1.8 to 10 cm (mean 4.2 cm). All cases showed predominant subcapsular location. Capsular retraction was seen in multinodular types, but not in solitary types. Two patients had intra-lesional calcifications. HEHs showed minimal enhancement (7/7 patients) on the hepatic arterial phase CT and rim-like enhancement (5/10 patients), minimal enhancement (2/10 patients), multilayered target enhancement (2/10 patients), and peripheral nodular enhancement (1/10 patients) on the portal venous phase CT. On MR images (n = 7), HEHs showed hypointensity on T1-weighted images and hyperintensity on T2-weighted images. Dynamic contrast-enhanced MR images revealed progressive centripetal fill-in enhancement (7/7 patients). On Gd-EOB-DTPA-enhanced hepatobiliary phase images, HEH manifested as homogeneous hypointensity (3/5 patients) and target-shaped hypointensity (2/5 patients). CONCLUSION HEH can manifest as single nodular, multinodular, or diffuse type. Common imaging features of HEH are multiple subcapsular nodules with coalescence, capsular retraction, peripheral, and delayed enhancement. However, HEH can manifest as a solitary subcapsular mass with minimal or rim-like enhancement at early phase and progressive centripetal fill-in enhancement during dynamic phase imaging, representing early stage of HEH. A single nodular type can progress to multifocal nodular type during follow-up.

Abstract
The diagnosis of vascular tumors is a challenging area in soft tissue pathology. Epithelioid vascular tumors pose a particular challenge. Due to the epithelioid morphology of the tumor cells, they can be misdiagnosed as a variety of other entities, including metastatic carcinoma or epithelioid sarcoma. Furthermore, it can be difficult to distinguish between different epithelioid vascular tumors. This review focuses on vascular tumors characterized by epithelioid endothelial cells, including epithelioid hemangioma, cutaneous epithelioid angiomatous nodule, epithelioid hemangioendothelioma, epithelioid sarcomalike hemangioendothelioma/pseudomyogenic hemangioendothelioma, and epithelioid angiosarcoma.

Abstract
OBJECTIVE To analyze the imaging characteristics of hepatic epithelioid hemangioendothelioma (EHE) and their correlation with histopathological findings. METHODS CT and MRI imaging and histopathological characteristics of five patients with hepatic EHE were retrospectively reviewed and the correlation of their imaging characteristics with pathological findings was analyzed. RESULTS A total of 92 lesions were found in the 5 patients, all presenting with multiple nodules. All the 92 lesions were located within a 2-cm zone heneath the hepatic capsule, i.e., the shortest distance from the horder of lesions to the hepatic capsule. 28 of the 92 lesions showed the "capsular retraction" sign. 36 lesions were found in three patients receiving MRI. 77.8% of the 36 lesions demonstrated the "halo" sign on a fat-suppression T2- weighted image, while 91.7% after contrast enhancement. A peripheral dark rim was found in 91.7% of the lesions on a fat-suppression T2-weighted image. In addition, 36.1% of the lesions showed slight internal or edge enhancement at the hepatohiliary phase. In the two patients receiving CT examination, 7 of 56 lesions demonstrated the "halo" sign. CONCLUSIONS Hepatic EHE may manifest as nodular lesions with predilection of peripheral subcapsular growth and nodular confluence, together with "halo" sign and " capsular retraction". The peripheral dark rim on a fat-suppression T2-weighted image and slight enhancement at the hepatobiliary phase can help to improve the accuracy of diagnosis and differential diagnosis of this hepatic tumor. MRI is superior to CT imaging to denict their intra-lesional characteristics.

METHODS The clinical data of a patient with pleural epithelioid hemangioend othelioma admitted to Peking Union Medical College Hospital were retrospectively analyzed and the related literature was reviewed. We searched databases PubMed, Embase, Ovid, Cochrane, Wanfang and Chinese National Knowledge infrastructure (CNKI) using the keyword "pleural epithelioid hemangioendothelioma" by December 2013. RESULTS The patient was a 40-year-old male presented with chest pain, and his chest CT scan revealed thickening of the left pleura and left pleural effusion. Biopsy of the pleura showed epithelioid tumor cells, and immunohistochemistry was positive for CD31, CD34 and vimentin. From January 1975 to December 2013, 18 related articles were retrieved and 29 cases of pleural epithelioid hemangioendothelioma were reported. Among all 30 cases, there were 20 males and 10 females, ranging from 31 to 82 years old, and the average age was 50. 3 years old. The etiology of the disease remained unknown. Chest pain, cough, and dyspnea were the common symptoms. Computed tomography usually revealed pleural effusion and pleural thickening or mass. Histological examinations revealed mainly epithelioid cells. Immunohistochemical stains were positive for vascular endothelial markers. The mean survival time was 8.2 months. CONCLUSIONS Pleural epithelioid hemangioendothelioma is rare and the etiology is unknown. Clinical and imaging manifestations are not specific, and diagnosis is relied on histological findings. It should be differentiated from adenocarcinoma, hemangiosarcoma, mesothelioma and pulmonary epithelioid hemangioendothelioma. There is no effective treatment and its prognosis is poorer than its pulmonary counterpart.

Abstract
Due to the increased vascularity as well as the unique anatomical structure, vascular lesions, which occur in the female reproductive system are common observed and diverse by their morphology. The majority of them are benign, including vascular malformations, lesions due to vascular hyperplasia, tumors with significant vascular component and others. Malignant vascular tumors are rare in the area of the vulva accounting about 1% of all vulvar lesions with vascular origin. Kaposi sarcoma, epithelioid hemangioepithelioma and epithelioid angiosarcoma have been reported with vulvar localization. With a view to their rare incidence, nonspecific clinical manifestation and aggressive behavior associated with high mortality, we present the most common malignant tumors of vascular origin arising in the vulva, as we emphasize on their epidemiology and clinical features, differential diagnosis and therapeutic algorithms for this rare type of malignancies.

Abstract
We describe the case of a 56-year-old man presenting a primary pulmonary epithelioid angiosarcoma versus malignant epithelioid hemangioendothelioma still alive, without recurrence at nearly two years after the beginning of the symptoms. The primary pulmonary angiosarcoma is extremely rare, being reported only in a handful of cases. Metastatic involvement of the lung (90%) is far more common than primary pulmonary involvement (10%). Various predisposing condition for the development of angiosarcoma have been described. Early diagnosis is not common, because of the rarity of angiosarcoma in the lung and consequent low index of suspicion. Due to the paucity of cases, there are no defined treatment regimens for this entity. However, there is a tendency for surgical intervention in all reported cases.

Abstract
BACKGROUND Epithelioid hemangioendothelioma (EHE) is an uncommon vascular soft-tissue tumor. Five cases of EHE in body fluids have been documented in the literature, all of them occurring in pleural effusions. This is the first description of cytomorphological features of EHE cells in ascitic fluid, accompanied by corresponding histopathological findings, clinical, and radiological data. CASE REPORT Our patient presented with several liver masses, peritoneal involvement, bilateral pleural effusions, and massive ascites. EHE was suspected on cytological examination of the ascitic fluid and was confirmed by immunohistochemical studies. Simultaneously, a liver mass was identified and diagnosed on biopsy as EHE, affording accurate histopathological correlation. Cytologically, EHE cells appear relatively bland, often obscured by reactive mesothelial cells, and dispersed singly or clustered. They often possess intracytoplasmic vacuoles, referred to as 'blister' or 'signet ring' cells. High-power examination shows slightly misshapen mildly hyperchromatic nuclei with inconspicuous nucleoli. Immunohistochemically, EHE cells express strong positivity with vascular markers (CD31, CD34 and factor VIII). They are nonreactive with mesothelial markers (calretinin and WT-1). CONCLUSION Recognition of the possibility of EHE cells in fluid by morphology should prompt proper immunohistochemical work-up to ensure an accurate diagnosis and timely patient management.
