Isolated spleen metastatic involvement from a colorectal adenocarcinoma complicated with a gastrosplenic fistula. A case report and literature review.

We present the case of a 66-year-old man with a moderately differentiated adenocarcinoma of the left colon and isolated spleen metastases, complicated with a gastrosplenic fistula. The patient underwent a palliative segmental resection of the primitive colic tumour, as no curative treatment could be offered in view of the spleen involvement. Adjuvant chemotherapy was started. After a few chemotherapy treatments, he developed a gastrosplenic fistula which required the resection of the spleen and the greater gastric curvature together. This fistula was, among other things, responsible for bad breath that immediately disappeared postoperatively. At the end of the chemotherapy course, all carcinologic features had also disappeared.
