Fibromatous Periorchitis MimickingTesticular Tumour in a 30-year-old Male

Abstract

Fibrous pseudotumours of the tunica vaginalis, epididymis, and spermatic cord are uncommon benign paratesticular masses. An extremely rare variant termed "fibromatous periorchitis" exhibits diffuse proliferative encasement of the testis and manifests grossly as an indurated testis reminiscent of malignancy. We present the case of a 30-year-old man who presented with a grossly enlarged right testis, benign scrotal ultrasound findings, and pathologic evidence of fibromatous periorchitis. The natural history, gross and histologic findings, and management of fibrous pseudotumours and fibromatous periorchitis are discussed. Understanding fibromatous periorchitis is crucial as it can prevent the need for radical orchidectomy, particularly in younger patients.
