Rare Manifestation of a Sigmoid Tumour: Ovarian Metastasis of Sigmoid Adenocarcinoma

Abstract

Colorectal cancer is the most frequently occurring colorectal cancer. The presenting signs are mainly transit disorders, rectal bleeding and abdominal pain. But colon cancer can be discovered after complications, namely obstructive syndrome or perforation. Synchronous metastases, although common at diagnosis (25% of patients), are an exceptional way to detect this cancer. We present a case of an isolated synchronous metastasis mistaken for an ovarian tumor and presenting as a previously asymptomatic tumor of the colon.
