A case of fibrous pseudotumor originating from tunica vaginalis testis.
A 32-year-old man presented with a complaint of painless palpable mass of the left scrotal content. Based on the preoperative diagnosis of scrotal or spermatic cordal benign tumor, local excision was performed. The histological diagnosis was scrotal fibrous pseudotumor. In Japan, only 35 cases of fibrous pseudotumor of the scrotum have been reported including our case. Orchiectomy was performed in 15 cases. Fibrous pseudotumor is a benign fibroproliferative lesion with dense hyalinization and sometimes focal calcification. It may be induced by previous intrascrotal inflammatory events such as epididymitis, an infected hydrocele, prior surgery or trauma. Although a relatively rare disease, a fibrous pseudotumor should be considered in the differential diagnosis of testicular and testicular tunica tumors. Our case was of a benign pseudotumor and orchiectomy could have been avoided.
