[Fibrous pseudotumor of the tunica vaginalis testis: a case report]

A case of fibrous pseudotumor originating from the tunica vaginalis testis is reported. A 42-year-old man was referred to our hospital with the complaint of painless nodules along his right epididymis. There was no evidence of specific history. Ultrasonography showed an isoechoic small mass attached to the right testis. Inflammatory granulomas of the right epididymis were suspected, and an operation was carried out. The operative appearance indicated tumors of various sizes originating from the tunica vaginalis testis. Tumors were resected with the tunica vaginalis testis. Pathological diagnosis of the tumor was a fibrous pseudotumor. We reviewed and discussed 33 cases of intrascrotal fibrous pseudotumor, including our case, in the Japanese literature.
