A rare cellular angiofibroma of the epididymis

Scrotal cellular angiofibroma: A case report and review of the literature

Scrotal cellular angiofibroma (CAF) is a rare, benign, soft-tissue paratesticular tumor that has been sporadically reported previously. We present a case of a 55-year old male with a scrotal mass ultimately diagnosed with scrotal CAF. Immunohistochemical analysis stained positively for desmin, CD34, and estrogen receptor. Our series is one of the only published to date demonstrating desmin-positive paratesticular CAF. Diagnosis of CAF remains difficult due to the sparsity of paratesticular CAF, its similar characteristics to spindle cell lipoma (SCL), and variability in immunohistochemical reporting.

Rare soft tissue tumor presenting as inguinal swelling

Cellular angiofibroma (CAF) is a rare, benign mesenchymal tumor found usually in the female vulvar and male inguinoscrotal regions. A 56-year-old Caucasian gentleman presented with left sided scrotal swelling after masturbating. The swelling was thought to be an inguinal hernia, although was found to be a soft tissue tumor upon dedicated cross-sectional imaging. Pathological evaluation of the mass revealed it to be a cellular angiofibroma. Diagnosis of CAF can only be made after resection and proper immunohistological staining. Ultrasonography and MRI are preferred for detailed soft tissue characterization. After surgical resection, follow-up imaging is recommended given potential risk of malignancy.
