Hemangioendothelioma of urinary bladder--report of rare case.
Urology, 2009Co-Authors: Deepali Jain, Narmada P. Gupta, Mehar Chand Sharma, Sridhar Epari, Surendra B. KollaAbstract:Although cavernous hemangiomas and a few cases of angiosarcoma in the urinary bladder have been described, only a single case of epithelioid Hemangioendothelioma of the urinary bladder has been documented in English publications, to date. Therefore, the biologic properties of epithelioid Hemangioendothelioma in this location are uncertain. We report the clinical and pathologic findings of a case of primary epithelioid Hemangioendothelioma of the urinary bladder in a 17-years-old boy. The tumor was treated by transurethral resection.

Epitheloid Hemangioendothelioma of urinary bladder.
Indian journal of urology : IJU : journal of the Urological Society of India, 2008Co-Authors: Narmada P. Gupta, Surendra B. Kolla, S. Panda, Mehar Chand SharmaAbstract:Epitheloid Hemangioendothelioma is an uncommon vascular neoplasm and has an unpredictable clinical behavior. It is characterized by round or spindle-shaped endothelial cells with cytoplasmic vacuolation. Most often, epitheloid Hemangioendothelioma arise from the soft tissues of the upper and lower extremities and it has borderline malignant potential. We describe the first reported case of epitheloid Hemangioendothelioma in the urinary bladder, which was treated by transurethral resection. The diagnosis was confirmed by immunohistochemistry.

CASE REPORT Kaposiform Hemangioendothelioma Arising from the Internal Auditory Canal
2015Co-Authors: J. M. Chang, B. J. Kwon, M. H. Han, H. S. Kang, K. H. ChangAbstract:SUMMARY: Kaposiform Hemangioendothelioma is a rare vascular tumor and locally aggressive endo-thelial-derived spindle cell neoplasm, which occurs almost exclusively in infants and adolescents. Radiologically, Hemangioendothelioma, including Kaposiform Hemangioendothelioma, is seen as a highly vascularized well-enhancing tumor, but no characteristic findings differentiate Kaposiform Hemangioendothelioma from other soft-tissue tumors, particularly when the tumor is too small to have any locally aggressive features or identifiable large vessels. We present a case of Kaposiform Hemangioendothelioma in the internal auditory canal that had no differential features on initial MR images and rapidly grew into a huge mass in a few months. Kaposiform Hemangioendothelioma is a rare vascular tu-mor found predominantly in infancy and early child-hood.1 It is often associated with Kasabach-Merritt syndrome, but not always.2 Concerning the histopathologic classification and biologic behavior of Hemangioendothelioma, Kaposi-form, retiform, and composite types of hemangioendotheli-oma are known to be intermediate malignant tumors, and epithelioid Hemangioendothelioma, to be a highly malignan

Primary Pleural Epithelioid Hemangioendothelioma
The Annals of thoracic surgery, 2011Co-Authors: Esther A. Kim, Subodh M. Lele, Rudy P. LacknerAbstract:Epithelioid Hemangioendothelioma is a rare neoplasm of vascular endothelial origin. It can develop in any tissue, but it occurs primarily in the soft tissue, liver, and rarely in the lung. Pulmonary epithelioid Hemangioendothelioma can present in the thorax in various manifestations. In the typical pulmonary forms, epithelioid Hemangioendothelioma presents as either a solitary nodule, or more often as multiple, small nodules. Pulmonary epithelioid Hemangioendothelioma involving the pleural space occurs in patients with disseminated disease [1, 2]. We present a case of primary pleural epithelioid Hemangioendothelioma.

Pseudomyogenic Hemangioendothelioma (epithelioid sarcoma-like Hemangioendothelioma, fibroma-like variant of epithelioid sarcoma) of the thoracic spine
European Spine Journal, 2013Co-Authors: Michael Mcginity, Viktor Bartanusz, Bradley Dengler, Lee Birnbaum, James HenryAbstract:Purpose Pseudomyogenic Hemangioendothelioma is a soft tissue tumor found in young adults, predominantly males. The tumor has been reported in various locations in the body, including the head, neck, chest wall, abdominal wall, genital region, and extremities. Until now, there has been no indication of occurrence in the spine. Methods A 25-year-old male presented with spinal cord compression, due to an extradural tumor involving the third and fourth thoracic vertebrae with extension into the right pleural cavity. Results Histopathologic examination revealed a pseudomyogenic Hemangioendothelioma, also described as epithelioid sarcoma-like Hemangioendothelioma, or fibroma-like variant of epithelioid sarcoma. Conclusion We describe the first occurrence of pseudomyogenic Hemangioendothelioma in the thoracic spine. According to previous reports based on other locations, the tumor has an indolent clinical course with a small risk of metastasis, therefore complete macroscopic excision is the treatment of choice. Local recurrence may occur even with complete surgical resection, requiring close follow-up; adjuvant therapy is warranted.
