The patient was a 57-year-old man, He was pricked with a thorn at the right sole of fourth toe, and the wound was hard to heal. But pigmentation or tumor did not appear at the lesion. At this time histopathological examination was not done. Afetrwards, the tumor appeared at the right inguinal region and grew larger up to about an egg-size The tumor was diagnosed histologically as metastatic malignant melanoma of a lymph node. So he was hospitalized to our dermatologic department and received chemotherapy (DTIC 500 mg, ACNU 100 mg and VCR 1 mg-one cure). After about one month, he feeled heart-burn and so visited our department. At the first endoscopic examination, there was a small polypoid lesion on the posterior wall of the greater curvature at the upper body of the stomach. The lesion showed a bull's eye form lesion with central black color covered by normal mucosa. Endoscopic diagnosis was metastatic malignant melanoma of the stomach. After anti-cancer chemotherapy, the slope became gradually gentle. At last the lesion was flattened and showed only pigmenta-tion, after five months from the first endoscopic examination; about seven months from the first chemotherapy. Endoscopic biopsy and cytology by thorny needle done at the first endoscopic examination revealed metastatic malignant melanoma of the stomach with melanin pigments which were confirmed by Masson stain. The primary focus may or may not be the right sole of the fourth toe with wound. Now, the patient was been in a good course for about two years.
