Spindle cells hemangioendotheloma generally reaches the extremities. Only one oropharyngeal localisation was described in the literature. We report the observation of a 41 years old patient who was operated twice for this localization. The patient presented in 2005 with a third recurrence with important local extension contraindicating surgical treatment. An external radiotherapy was carried out with a good local control of the lesion. In the light of this observation we will discuss physiopathology of this rare lesion and the various therapeutic options.

Background/aims: Epithelioid hemangioendothelioma (EHE) is an uncommon vascular tumor that commonly affects the liver. Hepatic EHE (HEHE) presents with variable clinical and histopathological features. We describe detailed clinico-histopathological features, differential diagnosis, and treatment outcomes of the cases of HEHE diagnosed in our center.

Pseudomyogenic hemangioendothelioma (PHE) is a rare, usually multifocal neoplasm typically affecting individuals in the second-to-fourth decade of life, with a male predominance. It often arises in the distal extremities and characteristically involves multiple tissue planes. Presentation of this neoplasm as a primary penile lesion is exceedingly rare, with only five cases previously documented in the literature.

Background: Preferentially expressed antigen in melanoma (PRAME) has been extensively studied in cutaneous melanocytic tumors and has proven valuable as a diagnostic adjunct in routine dermatopathology practice. However, its expression in cutaneous vascular neoplasms, particularly angiosarcomas (AS), remains largely unexplored.
Methods: To further explore PRAME expression in cutaneous AS, 18 cases of post-irradiation and 13 cases of primary cutaneous AS were evaluated for PRAME.
