Rare metastases of signet ring cell carcinomas to the scrotum: report of two cases.
Metastases of signet ring cell carcinomas to the scrotum are rare. We present 2 patients with this kind of tumor. In 1 patient, the scrotal pathologic examination helped to detect an adenocarcinoma of the appendix with a signet ring cell component, with an extent that had not been apparent clinically. The other patient was seen at an advanced stage of signet ring cell carcinoma of the sigmoid colon following surgical therapy and palliative chemotherapy. The route of metastases seems to be via seeding along the testicular cord and via lymphatic dissemination.
