Abstract;A seventy five-year-old woman visited our hospital with chief complain, subcutaneous tumor at the left wrist joint. She had left hemiplegia due to old stem infarction. Because of continuous swelling and pain at the wrist, tumor was resected. The first histological finding was metastatic tumor like small cell lung cancer (SCLC), so whole body examination of the cancer origin was done. But no abnormal changes was found. A few months later, subcutaneous swelling appeared again. So re-operation was performed. Pathological final diagnosis was Merkel cell carcinoma with electron microscopical findings. No reccurent evidence occured. Merkel cell carcinoma was rarely found as a neoplasma in the soft tissue of the wrist. It is difficult to diagnose between Merkel cell carcinoma and small cell lung cancer. We suggest that it is important to exercise the patient having the tumor reccurence short time after operation and tumor like small cell carcinoma at the subcutaneous lesions. (author abst.)
