Chondrosarcoma metastasis simulating a primary stomach tumor: a case report

Abstract

Gastric tumors are an important cause of cancer deaths. The main type is the primary gastric adenocarcinoma, and rarely secondary metastatic implants can be present. A 79-years-old woman sought medical attention due to a complaint of epigastralgia, unintentional weight loss, two cases of melena in the past two months, and a prior history of a chondrosarcoma of the thigh treated 13 years before. A neoplastic lesion was detected at the stomach during evaluation, and a gastrectomy was opted as a treatment. The immunohistochemical evaluation was compatible with a chondrosarcoma metastatic implant on the stomach. The patient obtained a survival superior to 5 years after surgery. Only one case of gastric metastasis from chondrosarcoma was described in the literature. We observed a great benefit in the use of surgical resection of the gastric lesion, showing that surgery may be considered in selected individuals with chondrosarcoma metastasis.
