Long-term survival in two cases of resected gastric metastasis of pulmonary pleomorphic carcinoma.

We report two pulmonary pleomorphic carcinoma patients both of which underwent surgical resection of solitary gastric metastases. A 69-year-old man developed anemia 5 months after right upper lobectomy for pulmonary pleomorphic carcinoma and gastric metastasis was detected endoscopically. He underwent distal gastrectomy and has survived for 5 years without any other recurrence or metastasis. Preoperative abdominal computed tomography detected a submucosal gastric tumor in a 62-year-old man with left upper lobe pleomorphic carcinoma. A gastrointestinal stromal tumor was suspected. Left upper lobectomy was performed followed by partial gastrectomy with splenectomy. The histologic diagnosis was primary pulmonary pleomorphic carcinoma with gastric metastasis. He has survived for 4 years without any other recurrence or metastasis. Resection of gastric metastasis following complete pulmonary pleomorphic carcinoma resection may be indicated if the metastasis is solitary.
