Abstract
BACKGROUND Kaposiform Hemangioendothelioma (KHE) is a rare vascular tumor of intermediate malignant potential which shows locally aggressive growth but only rarely metastasizes. It is mostly considered to be a tumor of pediatric population but its occurrence in the adults is not uncommon as once considered. Histologically, KHE can mimic other soft tissue neoplasms of different behaviors (e.g. Kaposi Sarcoma, hemangioma) and establishing the correct diagnosis is important for appropriate treatment. Herein, we describe the clinicopathological features of 8 cases of KHE which will be helpful in making their diagnosis. METHODS We reviewed pathology reports, microscopy glass slides and obtained follow up information about 8 cases of KHE which were diagnosed at our institution from January 2008 till June 2020. Immunohistochemical stain for HHV8 was also performed. RESULTS Age ranged from 7 months to 25 years. Seven patients were less than 20 years of age and one patient was 25 years old. Equal gender distribution was observed. Extremities were the most common sites of involvement, followed by head and neck, pancreas and ischiorectal region. 2 cases were resection specimen and all others were incisional biopsies. The largest tumor size was 5.5 cm in one of the resections. The incisional/fragmented tissues were all less than 5 cm in aggregate. Most cases showed predominance of nodular growth and a minor component of spindle cell population along with lymphangiomatosis like vascular channels, with evidence of microthrombi in 2 cases. Few multinucleated giant cells were observed in 2 cases. None of the cases exhibited significant nuclear atypia or mitotic activity. One of the cases arising in dermis showed underlying bone involvement. HHV8 was negative in 7/7 cases. CONCLUSIONS KHE can also involve adult population and it should always be considered in the differential diagnoses of a vascular lesion. Presence of multinucleated giant cells is a rare finding. Knowledge about histological features and potential mimics is helpful in avoiding misdiagnosis.

Abstract
Primary hepatic angiosarcoma (PHA) is rare, does not possess any characteristic tumor markers, is primarily observed in the elderly, and often presents with nonspecific symptoms, including discomfort or distension of the abdomen, weight loss and fatigue. Thus, PHA is difficult to diagnose, particularly if the patient presents no history of exposure to carcinogens, and its definitive diagnosis requires histological examination following surgery. Patients with PHA present poor long-term survival, and surgical resection of the tumor is currently the best treatment option for PHA. In the present report, the case of a 64-year-old man initially diagnosed with hydatid cyst, who was subsequently diagnosed with a giant PHA in the middle of the liver, is described. Further studies are required to investigate the diagnosis and treatment of PHA.

Abstract
INTRODUCTION The cytopathologic diagnosis of the rare vascular tumor epithelioid hemangioendothelioma (EHE) in patients who have no previous history of EHE or who have a complicated and/or misleading disease history is challenging. Furthermore, few studies have described the cytopathology of EHE. Herein, we identify 14 cases of EHE from 10 patients, some of whom had a history of epithelial tumor, and provide a detailed report of the cytomorphology of EHE, discuss the tumor's differential diagnoses, and describe ancillary examinations that may be helpful in diagnosing EHE cytologically, especially in patients with a complex disease history. MATERIALS AND METHODS We retrieved the slides of 14 cases of EHE archived between 2002 and 2009 in our institution's cytology section. Conventional direct smears and cell block sections were prepared from most fine-needle aspiration samples and from all effusion samples. Cell block sections were subjected to immunostaining for vascular, mesothelial, and epithelial markers. RESULTS EHE shared many morphologic features with other, more common tumors such as adenocarcinoma and mesothelioma. The defining cytologic feature of EHE was an intracellular lumen containing entrapped intact and degenerating erythrocytes, which was not present in every case. EHE cells were positive for the vascular markers CD34, CD31, factor VIII, and friend leukemia integration 1 transcription factor (FLI-1) and negative for epithelial and mesothelial markers. Clinicians provided information important to the diagnosis of EHE. CONCLUSIONS Carefully examining the smear and cell block sections for morphologic features indicative of EHE (eg, prominent cytoplasmic vacuolization, intranuclear cytoplasmic inclusions, and intracellular lumen containing entrapped intact and degenerating erythrocytes), confirming these findings with immunocytochemical staining, and communicating with clinicians are all important to correctly diagnosing EHE.

Abstract
Angiosarcomas account for a mere 2-3% of adult soft tissue sarcomas, with an overall poor outcome. Depending on the primary site, angiosarcomas have distinct prognosis. Primary hepatic angiosarcomas (PHAs) are much rare tumors, with worse prognosis compared with other angiosarcomas. PHA is reported to be associated with vinyl chloride, but the majority of patients were still with unknown etiology. As PHA lacks specific symptoms, signs, or images, pathological diagnosis is necessary. The review summarizes 25 articles published from January 2000 to December 2012, including 64 cases of PHA with detailed information. Survival curves are estimated using the Kaplan-Meier method by SPSS 21.0. We find that the median survival time is 5 months; local excision alone or combination with adjuvant therapy is the optimal choice, with median survival time of 17 months. In addition, liver transplant is abandoned for high recurrence rate; emergent transcatheter arterial embolization is thought to be an efficient method for controlling intra-abdominal bleeding; and transcatheter arterial chemoembolization and chemotherapy may be helpful in improving survival.

Abstract
Epithelioid hemangioendothelioma (EHE) of the liver is an extremely rare tumor that masquerades as an epithelial neoplasm and poses significant diagnostic pitfalls for the cytopathologist. This report describes a 64-year-old woman whom on computerized tomography was found to have multiple peripherally calcified hypodense lesions throughout the liver and an ipsilateral adrenal mass. Fine needle aspiration and needle cores biopsies of the largest liver lesion showed epithelioid cells and spindle cells in fibrous stroma. The epithelioid cells had round or oval, hyperchromatic nuclei with smooth nuclear contours, delicate cytoplasm and indistinct cytoplasmic borders. Rare cells had intracellular vascular lumen containing fragmented or intact red blood cells. The cells were individually dispersed or arranged in nests and vague tubular arrays. No mitotic figures or necrosis were seen. An immunohistochemical profile demonstrated diffuse CD31 and focal CD 34 and nuclear Fli-1 immunoexpression and low Ki-67 proliferative activity (1%) within lesional cells confirming the diagnosis of EHE. The differential diagnosis of EHE which includes cholangiocarcinoma, hepatocellular carcinoma, metastatic carcinoma and melanoma is discussed.

Abstract
To determine cytologic features of epithelioid hemangioendothelioma (EHE) that would enable accurate diagnosis, we evaluated fine-needle aspiration biopsy (FNAB) smears from 11 histologically confirmed EHEs. The variably cellular smears comprised dispersed single cells and occasional cell aggregates. Dense stromal fragments were present in association with some tissue fragments. The cells were epithelioid, containing moderate or large amounts of dense cytoplasm. Nuclei exhibited mild pleomorphism, and nuclear grooves were identified in all cases. At least occasional intranuclear pseudoinclusions (INPIs) and intracytoplasmic lumina (ICLs) were present in all cases and in 9 cases (82%), respectively, and rare erythrocytes were seen within ICLs in 5 cases (45%). Mitotic figures were identified in 4 cases (36%). The background was bloody in 6 cases (55%) and contained hemosiderin and/or hemosiderin-laden macrophages in 5 cases (45%). The combination of the following features in FNAB samples should raise strong suspicion for EHE: predominantly dispersed single cells with occasional cohesive cell clusters; epithelioid cytomorphology; dense cytoplasm with well-defined cytoplasmic borders; ICLs (with or without erythrocytes), INPIs, and nuclear grooves. The presence of these features should prompt correlation with clinical, radiologic, and histologic features and immunohistochemical evaluation using vascular markers.

Abstract
Epithelioid hemangioendothelioma is a rare vascular neoplasm of low-grade malignancy. We observed a case of epithelioid hemangioendothelioma arising in a cervical lymph node. Fine needle aspiration cytology showed several characteristic findings of epithelioid hemangioendothelioma, that is, nuclear inclusion bodies, nuclear grooves, and amorphous material, in addition to physaliform chromatin pattern of a new clue. By reviewing the reports, the prevalence of these is clarified. Complex appearance of these findings is useful in the diagnosis.

Abstract
Epithelioid angiosarcomas (EAS) of kidney are rare and aggressive tumors with noncharacteristic imaging features that overlap with those of inflammatory conditions and renal cell carcinoma (RCC). We report the fine-needle aspiration (FNA) cytology findings of a case of EAS that involved the left kidney of an 83-year-old male. The smears and cell block sections showed pleomorphic epithelioid cells with ample cytoplasm, eccentric nuclei, occasional cytoplasmic hyaline globules, and rare intracytoplasmic lumina. Immunohistochemical stains performed on cellblock sections showed that the tumor cells were positive for vimentin, CD31, CD34, Factor VIII, and CD10, but showed no staining for cytokeratins AE1/AE3 and 8/18, HMB45, CD45, smooth muscle actin, and S100. The morphological and immunohistochemical distinction between EAS, primary tumors of the kidney, and other epithelioid and rhabdoid neoplasms is discussed.

Abstract
Hepatic epithelioid hemangioendothelioma (EH) is a rare vascular neoplasm. An accurate radiologic diagnosis is usually difficult due to the presence of multiple nodules, simulating metastatic carcinoma. Though histologic features of this tumor are well described, cytologic reports of hepatic EH are very few in the available literature. We describe a case of a young healthy adult male who was found to have multiple hepatic masses on radiologic investigations. A guided fine needle aspiration demonstrated a poorly differentiated neoplasm. The diagnosis was made on core biopsy assisted by immunohistochemistry, which showed characteristic features of EH. He is doing well 14 months after diagnosis, without surgical excision or chemotherapy. An accurate diagnosis of hepatic EH on aspiration cytology requires an adequate specimen and awareness of its cytologic features, including discohesive atypical cells with intracytoplasmic lumina and intranuclear inclusions. Since this tumor is usually unresectable but has a favorable prognosis as compared to hepatocellular carcinoma, a correct diagnosis is essential for appropriate management and prognostication.

Abstract
Malignant hepatic epithelioid hemangioendothelioma (HEH) is a rare malignant tumor of vascular origin with unknown etiology and a variable natural course. The authors present a comprehensive review of the literature on HEH with a focus on clinical outcome after different therapeutic strategies. All published series on patients with HEH (n = 434 patients) were analyzed from the first description in 1984 to the current literature. The reviewed parameters included demographic data, clinical manifestations, therapeutic modalities, and clinical outcome. The mean age of patients with HEH was 41.7 years, and the male-to-female ratio was 2:3. The most common clinical manifestations were right upper quadrant pain, hepatomegaly, and weight loss. Most patients presented with multifocal tumor that involved both lobes of the liver. Lung, peritoneum, lymph nodes, and bone were the most common sites of extrahepatic involvement at the time of diagnosis. The most common management has been liver transplantation (LTx) (44.8% of patients), followed by no treatment (24.8% of patients), chemotherapy or radiotherapy (21% of patients), and liver resection (LRx) (9.4% of patients). The 1-year and 5-year patient survival rates were 96% and 54.5%, respectively, after LTx; 39.3% and 4.5%, respectively, after no treatment, 73.3% and 30%, respectively, after chemotherapy or radiotherapy; and 100% and 75%, respectively, after LRx. LRx has been the treatment of choice in patients with resectable HEH. However, LTx has been proposed as the treatment of choice because of the hepatic multicentricity of HEH. In addition, LTx is an acceptable option for patients who have HEH with extrahepatic manifestation. Highly selected patients may be able to undergo living-donor LTx, preserving the donor pool. The role of different adjuvant therapies for patients with HEH remains to be determined.

Abstract
Epithelioid hemangioendothelioma (EHE) is an uncommon vascular tumor with biological behavior intermediate between hemangioma and angiosarcoma. It rarely occurs in the oral cavity. We report a case of an 81-yr-old woman with a 2-mo history of a 2 x 2 cm2 submucosal buccal mass. Fine needle aspiration (FNA) smears were paucicellular and showed mainly single atypical large epithelioid cells in a bloody background. The atypical cells had abundant dense cytoplasm, some with fine vacuoles. Occasionally, cells with large cytoplasmic lumina were seen. Cytology preparations from fresh tissue received for frozen section revealed numerous neoplastic cells with large intracytoplasmic lumina, some of which contained red blood cells. In addition, cells with distinct intranuclear inclusions were present. Histologic sections and immunohistochemical stains confirmed the diagnosis of EHE. Although the histologic features of EHE are well recognized, reports of FNA cytology findings are sparsely existent in the literature as several case reports. The characteristic cytological features of EHE are reviewed in this report. We believe that the diagnosis of this rare tumor can be suggested when an adequate FNA specimen is obtained.

Abstract
BACKGROUND Angiosarcoma that arises after breast-conserving therapy can present clinically as a cutaneous and/or subcutaneous breast lump, which is misinterpreted easily as a recurrence of carcinoma. To the authors' knowledge, the role of fine-needle aspiration (FNA) cytology in the early diagnosis of this life-threatening complication of breast carcinoma therapy has not been established fully. METHODS The authors studied three new patients with this type of secondary angiosarcoma diagnosed by FNA biopsy and immunocytochemistry, reviewed the literature on the topic, and examined relevant differential diagnostic issues. RESULTS Patients presented with a discrete skin lump that had arisen several years after breast-conservative therapy for early-stage breast carcinoma near the scar from the previous surgery. The lesions were interpreted clinically as recurrent carcinoma. FNA yielded moderately cellular to highly cellular samples with variable patterns of cellular aggregation. Cells were epithelioid and spindle-shaped. Angioformative changes were subtle, and the overall picture suggested an epithelial malignancy, possibly a metaplastic carcinoma. Immunostaining of smears, however, provided conclusive evidence of the endothelial differentiation of tumor cells, and an FNA diagnosis of angiosarcoma was rendered in all patients. The histopathology of all surgically excised tumors confirmed the diagnosis of high-grade angiosarcoma. CONCLUSIONS Based on the authors' experience, the FNA cytologic appearance of angiosarcoma that presented as a breast skin nodule in a breast carcinoma survivor easily could have been misinterpreted as carcinoma. A correct diagnosis of this tumor relies on the proper evaluation of clinical findings and, as also shown by a review of the literature, requires immunocytochemical evidence of endothelial differentiation.

Abstract
Epithelioid mesenchymal neoplasms (EMNs) are rare tumors that share cytological, histological, and immunohistochemical features with epithelial tumors. It is important to distinguish EMNs from epithelial tumors in cytology specimens due to their different clinical management and prognosis. The cytomorphological features of histologically confirmed EMN were reviewed. Twenty-one cytological specimens of EMN were evaluated and characterized by polygonal cells with moderate to abundant dense cytoplasm, prominent nucleoli, and pleomorphism. Additional findings included the presence of a distinct population of spindle cells, hemosiderin-containing cells, multinucleated cells, and granuloma-like structures in selected cases. Cytokeratin immunoreactivity was seen in two cases and was negative in one case. This study shows that the cytological features of EMNs and epithelial tumors overlap; nonetheless, some features are more helpful in suggesting EMN. A panel of immunocytochemical studies must include specific mesenchymal markers to avoid a misdiagnosis of carcinoma in cases of cytokeratin-positive EMN.

Abstract
To characterize the cytological features of angiosarcomas, we reviewed the fine-needle aspiration material and corresponding histologic sections of 29 tumors in 23 patients. Histologically, 24 tumors were of the classic type, and 5 were epithelioid angiosarcomas. The original corresponding cytologic diagnoses were as follows: angiosarcoma, 17 cases; sarcoma not otherwise specified, 8 cases; and rhabdomyosarcoma, 1 case. Three samples were cell-poor and were considered suspicious of malignancy. The review of cytology samples showed that smears were cell-rich in 17 tumors and cell-poor in 12 tumors. A hemorrhagic background was present in 9 cases. Tumor cells were polymorphous, including spindle-shaped, round to oval, and polygonal epithelioid cells and giant cells in different proportions. Erythrophagocytosis was seen in 12 tumors. Smears of classic angiosarcomas were polymorphous and lacking specific characteristics, whereas smears of epithelioid tumors were morphologically similar and composed of round to oval and polygonal, epithelial cells frequently arranged in clusters, and showing erythrophagocytosis. The wide spectrum of cellular components of angiosarcomas accounts for the difficulty in establishing accurate tumor typing, particularly with cell-poor samples and low-grade classic angiosarcoma. Entities to consider in the differential diagnosis are carcinoma, epithelioid sarcoma, pleomorphic rhabdomyosarcoma, and malignant melanoma.

Abstract
Cytologic characterization of malignant vascular neoplasms (MVN) is difficult due to the wide range of differential diagnoses and sampling errors. The objective of this study was to identify criteria helpful in the cytologic diagnosis of MVN. The clinical presentation and cytomorphologic features of 22 angiosarcomas and two hemangioendotheliomas were analyzed. The criteria evaluated included cellularity, cellular arrangement, cell shape and size, pleomorphism, cytoplasmic borders, nuclear shape and number, chromatin pattern, nucleoli, background, and presence of angioformative structures. A previous history of MVN was noted in 18 of 24 patients. Specimens with epithelioid morphology were more cellular and pleomorphic and contained multinucleated cells. Specimens with spindle morphology were usually less cellular and less pleomorphic. Angioformative structures were identified in 11 of 24 cases. Awareness of features suggestive of MVN is necessary to raise the possibility of vascular origin, which can be confirmed with appropriate immunocytochemical studies.

Abstract
Rarely, spindle-cell lesions in liver fine-needle aspiration biopsies (FNABs) are encountered. A retrospective review of our experience with lesions that are mesenchymal in origin or appearance was undertaken to elucidate the frequency and spectrum of these lesions. Image-guided liver FNABs performed over a 3-year period (n = 585) at our institution (1996-1998) were retrospectively evaluated. Cytologic smears, cell block preparations, and clinical follow-up of lesions with spindle-cell morphology were reviewed. Twenty-nine of 585 cases were of spindle-cell morphology (5%). Hemangiomas (n = 12, 41%) and metastatic sarcomas (n = 6, 21%) comprised the largest categories, followed by granulomatous inflammation (n = 3, 10%). Other cases included primary angiosarcoma and fibrolamellar hepatocellular carcinoma. The most frequent spindle-cell liver lesion encountered is hemangioma, followed by metastatic leiomyosarcoma and granulomatous hepatitis. Awareness of diagnostic possibilities, special attention to specimen adequacy, and use of ancillary procedures can maximize diagnostic yield.

Abstract
Primary angiosarcoma of the liver accounts for up to 2% of all primary liver tumors and is the second most common primary malignant neoplasm of the liver. Approximately 10 to 20 new cases are diagnosed every year in the United States and the prevalence varies from 0.14 to 0.25 per million. In an autopsy series from Chicago, one hepatic angiosarcoma was noted for every 30 cases of hepatocellular carcinoma.

Abstract
We report the cytologic features of 15 cases of angiosarcoma from various sites and include 14 fine-needle aspiration (FNA) biopsy specimens and 1 pleural fluid specimen. Six were initial diagnoses with histologic confirmation; an additional case in the liver was an initial diagnosis without tissue confirmation. One case represented lymph node metastasis from a primary prostatic epithelioid angiosarcoma. In 10 cases, immunohistochemical staining for factor VIII-related antigen, CD34, CD31, or Ulex europaeus agglutinin I was performed on the cytology or histology specimen. The aspirates varied in cellularity, and the degree of nuclear atypia ranged from relatively bland in a case of low-grade angiosarcoma of the prostate to highly pleomorphic in a lymph node metastasis from a facial cutaneous angiosarcoma. Vasoformative features such as intracellular RBCs, well-formed vessels, attempts at microacinar/lumen formation, and intracytoplasmic lumens were variably present. The background was bloody in all specimens, with necrosis in rare cases. This cytologic series emphasizes that the cytologic features are heterogeneous but that the diagnosis can be suggested by fine-needle aspiration (FNA) when vasoformative features are present. The diagnosis can be made conclusively by FNA with immunocytochemical confirmation of endothelial differentiation.
