29. Simultaneous development of adenocarcinoma and gastrointestinal stromal tumor (gist) in the stomach: Case report
Main Article Content
Abstract
Adenocarcinomas and gastrointestinal stromal tumors (GISTs) are two distinct types of tumors that originate from different cell layers of the digestive tract. Co-development of these two types of tumors in the stomach is rare. We report a case of synchronous development of adenocarcinoma and GIST in the stomach. The patient was male and 61 years old. Gastric endoscopy was done in antrum area showing 2x3cm wart ulcer and 3cm diameter submucosal tumor. The patient underwent lower pole gastrectomy and pean anastomosis. Histopathology and immunohistochemistry showed moderately differentiated adenocarcinoma, no lymph node metastasis (T2N0M0) and low-risk GIST. At 50 months after surgery, the patient’s condition was stable; the anastomosis was good; and there was no sign of recurrence and metastasis.
