Cellular angiofibroma of the inguinoscrotal region with cytologic atypia and abundant adipose tissue simulating liposarcoma: a case report

Cellular angiofibroma (CAF) is a rare benign mesenchymal neoplasm of the vulvovaginal or inguinoscrotal regions. We report a case of CAF with abundant intralesional fat and focal cytological atypia that raised the possibility of liposarcoma. We review the literature and discuss the significance of these findings and the differential diagnosis of CAF.
