title: Recurrent peritoneal carcinomatosis in the scrotum in a patient with a history of mucocele of the appendix.
abstract: Paratesticular metastases are rare entities and a paratesticular metastasis of a mucinous appendiceal adenocarcinoma with peritoneal carcinomatosis has not been reported in the literature in the last 15 years. We present a case of mucinous appendiceal adenocarcinoma that progressed to peritoneal carcinomatosis. Twenty months following surgery and intraperitoneal therapy, the patient presented with testicular pain and swelling. Ultrasound examination raised suspicion for a neoplastic process and pathology confirmed a metastatic mucinous adenocarcinoma of appendiceal origin. Radiologists should be cognizant of potential paratesticular metastases in patients with a known history of malignancy with new testicular pain and swelling.
