Paratesticular colon cancer metastasis in an area of remote trauma

Abstract

A 53-year-old man with a history of colon adenocarcinoma and remote scrotal trauma resulting in a palpable nodule. Gradual increase in the size of this lesion over the year prior to his presentation to our clinic prompted scrotal ultrasound that demonstrated a 1.1 cm solid lesion, which appeared to arise from the right epididymal tail. Subsequent positron emission tomography (PET) scan showed intense focal uptake at the base of the right testicle, suspicious for epididymitis versus underlying neoplasm. Scrotal exploration through an inguinal approach revealed a paratesticular mass. Frozen section from an excisional biopsy was positive for adenocarcinoma. Radical orchiectomy was completed. Final pathology returned as metastatic adenocarcinoma involving soft tissue; testis and spermatic cord were without diagnostic abnormalities and surgical margins were not involved. Subsequent analysis was consistent with colorectal origin. The patient recovered well from surgery and is continuing treatment of metastatic colon cancer per the medical oncology team.

Keywords: colon cancer; urology.
