Abstract

Oligometastatic disease is a relatively new concept that refers to an intermediate stage between disseminated and localized cancer. Most frequent locations for colorectal metastasis are lung and liver. We present an a typical case of an 85-year-old woman who was diagnosed with a low-grade adenocarcinoma in left colon; she underwent a left laparoscopic hemicolectomy which resulted in a stage IIIb. After 24 months of follow-up, an increase of carcinoembryonic antigen (CEA) leads to the diagnosis of two metastatic lesions in two uncommon locations: spleen and myometrium. Stepwise surgical resection of both lesions was performed without complications. Spleen and uterus are organs that are rarely affected in colorectal cancer, the affection of both organs being even more infrequent. Despite the atypicality, surgical treatment is a valid strategy in this case of oligometastatic disease, which enables the disease-free survival of the patients.
