BACKGROUND:

Cellular angiofibroma is a very rare tumor, it was described as a mesenchymal neoplasm, mainly made up of two components: spindle cells and vascular structures. Cellular angiofibromas are small-delimited malignancies and characteristically occur in women between 40 to 50 years of age.

CLINICAL CASE:

A 15-year-old female patient, with no pathological history of importance for the current condition, went to the medical unit due to the presence of a 1-year evolution vulvar mass, which was growing rapidly, 10 x 4 cm vulvar mass, horseshoe-shaped bearing the contour of the vulva, another tumor dependent on the previous in the clitoris area (7 x 5 cm), simulating a phallus, fixed to deep planes, not painful on palpation, mobile, circumscribed, of soft consistency, with growth of body hair in an androgenic position. In the surgical event, a tumor resection was performed, beginning an approach by the external part of the majors labia, respecting the urethral meatus and clitoris, an increase in vascularity was observed, dissecting the tumor in its entirety. The histopathological report was of cellular angiofibroma. The evolution of the patient was favorable.

CONCLUSION:

The cellular angiofibroma of the vulva is a mesenchymal neoplasm with the own clinical, morphological and immunohistochemical characteristics. The case presented is the first identity developed in an adolescent patient.
