Massive cellular angiofibroma of the vulva: a case report.

Cellular angiofibroma is a rare benign mesenchymal tumor, typically occurring in the vulvar region of middle-aged women. This report highlights the importance of histological analysis in diagnosing this uncommon condition and emphasizes its benign nature and straightforward management. We present a case of a 58-year-old North African woman who had a large, well-defined mass in the left labia majora, which had been evolving over 2 years. MRI confirmed the resectability of the tumor by delineating its boundaries. The tumor, despite its slow growth leading to delayed diagnosis, was effectively treated with wide surgical excision. Diagnosis was confirmed through histological and immunohistochemical evaluations, revealing spindle cell proliferation with thick-walled vessels. Cellular angiofibroma, although initially alarming due to its size, is generally managed successfully with surgery and prognosis is favorable with a low risk of recurrence.
