Paratesticular fibrous pseudotumor: a report of five cases and literature review

Abstract

Paratesticular fibrous pseudotumor is a rare benign tumor that originates from intrascrotal tissue, such as tunica vaginalis, epididymis, or spermatic cord. Five cases of fibrous pseudotumor in our hospital were reviewed retrospectively, and the clinical manifestations were analyzed. Three cases of unilateral nodules, comprising one case located in the tunica vaginalis and two cases located in the epididymis, underwent local excision of the unilateral nodule. Two cases of diffuse incrassation in the tunica vaginalis underwent right radical orchiectomy. Postoperative pathological examination showed that all were fibrous pseudotumors. An average follow-up of 26 months showed uneventful results without recurrence for all patients. Fibrous pseudotumor is not a neoplasm but a reactive fibrous inflammatory hyperplasia. Definitive diagnosis requires pathological examination. Radical orchiectomy should be avoided when possible, and local excision should be performed because of the lack of obvious evidence of potential malignancy.
