TFE3 rearranged epithelioid hemangioendothelioma of the lymph node: A rare primary presentation of vascular tumor
We present a 49-year-old male patient who presented with an inguinal mass but was otherwise asymptomatic. Clinical and radiological workup failed to reveal any other primary lesion. The lymph node was excised and the histomorphological examination showed an epithelioid and spindle neoplasm with chondromyxoid stroma. The diagnosis of epithelioid hemangioendothelioma was suspected based on histomorphology and immunohistochemistry, which showed diffuse positivity for CD31, CD34, and TFE3 stains. This was further confirmed by the fluorescent in-situ hybridization (FISH) technique that showed TFE3 gene rearrangement.PMID:385637...

A case of primary pleural epithelioid hemangioendothelioma achieving stable disease with paclitaxel treatment: A case report and literature review
Pleural epithelioid hemangioendothelioma (EHE) is exceptionally rare, and the prognosis for pleural EHE is grim, typically resulting in a survival of less than 1 year. In this case report, we present the case of a 45-year-old woman who endured 1 month of right-sided pleuritic chest pain, was diagnosed with right pleural EHE, and achieved an 11-month progression-free survival following paclitaxel treatment. AbstractEpithelioid hemangioendothelioma (EHE) is a rare vascular neoplasm with a clinical behaviour that falls between a benign hemangioma and a high-grade angiosarcoma. Pleural EHE is exceptionally rare, and its progno...

Pseudomyogenic Hemangioendothelioma Arising in the Maxillary Sinus, an Uncommon and Misdiagnosed Tumor: A Case Report
Ear Nose Throat J. 2024 Mar 20:1455613241239859. doi: 10.1177/01455613241239859. Online ahead of print.ABSTRACTPseudomyogenic hemangioendothelioma (PMHE) is a rare vascular neoplasm with an intermediate to low-grade malignant potential. Only 5% of PMHEs occur in the head and neck. This tumor exhibits different histological patterns and mimics other vascular tumors, myoid tumors, or carcinomas. The distinction between these tumors can be a very challenging situation for pathologists. In this article, we report the first case, to our knowledge, of PMHE arising in the maxillary sinus, to highlight this uncommon entity and dis...
