Background and Aim: The incidence of benign solid tumors in vulvar area is very rare. These tumors include fibromas, fibromayomas, lipoma, hemangiomas, neurofibromas and endometriomas. Lipoma is the most prevalent soft tissue mesenchymal tumor, but the incidence of this tumor in the vulva is very rare. The aim of this study was to report a rare case of vulvar lipoma in an adolescent girl.
Case report: A single 16-year-old girl patient referred to gynecology clinic of Imam Khomeini hospital; in Tehran in Sep 2018 with chief complain of a growing vulvar mass from 3 years ago. In physical examination, a soft mass of 4×7 cm with regular border was detected in the medial aspect of right labia majora. There were no evidence of erythema, discharge, ulcer or tenderness. A yellow encapsulated tumor with soft consistency similar to adipose tissue was removed. Diagnosis of lipoma was confirmed by histopathological examination.
Conclusion: Although vulvar lipoma is a rare tumor especially in adolescent age, complete excision and confirmation of the benign nature of this tumor by histopathological examination should be considered necessary.
