喀血と鼠径部結節を呈する76歳男性：症例報告

Epithelioid hemangioendothelioma is a rare vascular neoplasm with clinical behavior that varies from indolent to aggressive. While the clinical presentation of epithelioid hemangioendothelioma may be variable, the diagnosis of epithelioid hemangioendothelioma is based on histologic and immunohistochemistry features. We describe a case of epithelioid hemangioendothelioma presenting as a groin nodule in a 76-year-old man. He was admitted to hospital with progressive hemoptysis, accompanied by a growing, ulcerated right groin nodule. Excisional biopsy confirmed a diagnosis of epithelioid hemangioendothelioma. The patient opted for palliation and died 1 month after hospital admission. Our case highlights an atypical presentation of epithelioid hemangioendothelioma characterized by hemoptysis and a solitary groin nodule, underscoring the importance of timely diagnosis and management.
