Abstract

<p>We report a case of epithelioid hemangioendothelioma of the lower lip. Epithelioid hemangioendothelioma is a malignant vascular tumor derived from vascular endothelial cells.This tumor affecting the lip is rare. A 34-year-old woman visited our department with the chief complaint of a localized mass in the left lower labial mucosa. An excisional biopsy was performed based on a clinical diagnosis of lower lip tumor. Histopathologically, the lesion was diagnosed as an epithelioid hemangioendothelioma. About one month after the excisional biopsy, an additional resection was performed with a safety margin of about 1 cm. Since it was a curative resection, no postoperative treatment was performed. The postoperative course was uneventful, with no signs of recurrence 32 months after the surgery.</p>
