Angiomyofibroblastoma: Imaging and histopathology of a rare benign mesenchymal tumor

Angiomyofibroblastoma is a rare mesenchymal benign tumor that frequently occurs in young- to middle-aged women, arising from the genital tract. There are many overlapping radiological and immunohistochemical features with other stromal cell lesions, making the diagnosis difficult. We report here a case of a 29-year-old woman admitted for a pelvic mass, in whom, the histopathological and immunohistochemical studies led to the diagnosis of angiomyofibroblastoma.

Introduction:The differential diagnosis of female pelvic tumors is broad and most frequently arises from the reproductive organs. This paper reports an uncommon benign pelvic tumor of mesenquimal origin. Case report:A 71-year-old woman with cellulitis at the right gluteal region underwent transvaginal pelvic ultrasound, which showed a large solid and cystic pelvic tumor. Diagnostic investigation through magnetic resonance imaging played a fundamental role in determining the origin of the lesion in the right ischiorectal fossa. Histopathological and immunohistochemical studies of the specimen defined a benign genital stromal tumor: angiomyofibroblastoma. Conclusion:Defining the origin of pelvic lesions at imaging exams and, mainly, histopathological analysis is decisive to make the correct diagnosis. Although vulva and vagina are the most common sites of angiomyofibroblastoma, this neoplasm can rarely occur in the pelvic and extrapelvic tissues.
