[Peri-testicular fibromatosis (testicular fibrous pseudotumor)].

OBJECTIVE: We report a case of fibromatous periorchitis, a rare entity that may have differential diagnosis problems with other lesions. METHODS: Our patient underwent a surgical procedure with resection of the tunica vaginalis testis after intraoperative histological evaluation. RESULTS: Findings observed in both intraoperative biopsy and specimen histopathological study were key for diagnosis. CONCLUSIONS: Although macroscopic appearance of the lesion can be of great value, fibromatous periorchitis diagnosis is based on the histologic features, being important to avoid erroneous therapeutic decisions.
