Small cell lung cancer with extensive cutaneous and gastric metastases.

A case of a 60-year-old Japanese woman with small cell lung cancer involving skin and stomach is reported. She was diagnosed as primary small cell lung cancer accompanied by extensive cutaneous metastases. Three months after the last chemotherapy, she complained of nausea and vomiting. Brain CT scan showed no evidence of central nervous system involvement. Upper gastrointestinal study and upper gastrointestinal fiberscopy revealed multiple metastatic gastric tumors. Skin and stomach are uncommon metastatic sites for any malignancy. Furthermore, only a few cases with gastric metastasis could be diagnosed during their lifetime.
