Abstract
|
|
|
|
A 67 year-old man was admitted due to findings that were suspicious for malignancy on gastroscopy at a primary clinic. We also performed gastroscopy and this showed the presence of a 3 cm sized nodular elevated lesion at the angle of the stomach. A biopsy demonstrated the presence of adenocarcinoma of the stomach. A distal gastrectomy with D2 lymph node dissection was performed and the microscopic features of the resected specimen confirmed the diagnosis of adenocarcinoma of the stomach and also metastatic large cell neuroendocrine carcinoma of lymph nodes of an unknown primary origin. Although double primary gastric adenocarcinoma and gastric neuroendocrine tumor with regional lymph node metastasis has been seldom reported, a double primary carcinoma of gastric adenocarcinoma and metastatic large cell neuroendocrine carcinoma of lymph nodes has seldom been reported. We report on this unusual case along with a review of the relevant medical literature.
