Paratesticular cellular angiofibroma: a case report

Paratesticular cellular angiofibroma is a rare benign mesenchymal tumor. The optimal management is surgical resection due to the difficulty of preoperative accurate diagnosis. A 51-year-old Japanese male visited our hospital complaining of asymptomatic left scrotal swelling. Physical examination revealed a nontender elastic paratesticular mass (5.5 cm in diameter). Although testicular germ cell tumor was ruled out clinically, the possibility of malignant potential remained for the tumor. Since the patient consented to complete resection, a transinguinal radical orchiectomy was performed. The pathological diagnosis revealed cellular angiofibroma. The patient recovered without perioperative complications, and no apparent recurrence was observed at 5 years after surgery. The pathological findings were compatible for cellular angiofibroma. The tumor was successfully resected, and no apparent recurrence was observed at 5 years after surgery.
