Colic metastases of alveolar soft-part sarcoma: a case report and review of the literature.

Alveolar soft-part sarcoma is a rare soft tissue malignant tumor that commonly arises in skeletal muscles or musculofascial planes in children and young adults. Metastases of lung, brain, and bone are often present at the time of diagnosis or appear late in the course of disease. We present the first case, to our knowledge, of colic metastases in a 43-year-old woman who had a leg primary tumor more than 15 years ago and multiple lung and brain metastases. The treatment of these two caecal metastases, revealed by an anemia, consisted in laparoscopic right colectomy.
