Abstract

Paratesticular tumors are rare, especially when they are metastatic. Most of them originate in the prostate, kidney, gastrointestinal tract, lung, and breast. The most common site of metastasis from the gastrointestinal tract is the colon. A 75-year-old male presented with a painless and tense right scrotal mass. He underwent a radical right orchiectomy, and the pathology revealed mucinous cystadenocarcinoma of the paratesticular tissue. Computed tomography revealed focal wall thickening at the rectosigmoid junction and liver nodules. The colonoscopic biopsy of the mass showed adenocarcinoma. Immunohistochemical staining of both sites confirmed the diagnosis of colorectal adenocarcinoma metastatic to the scrotum.
