転移性皮膚癌 鼻尖に生じた１症例の報告と新潟大学における２２症例の検討

Abstract

A 64-year-old man had a rapidly growing tumor on his nasal apex. He had been treated for his lung cancer with left pneumonectomy and mediastinal lymph node clearing 6 months before. Since histological findings of the nose tumor and the lung tumor were very similar, the nose tumor was diagnosed as a metastatic skin cancer originating from lung cancer.We also studied 22 cases of metastatic skin cancers in our hospital experienced for 8 years. The mean age at their first visit was 63.4 years old. The most frequent primary tumors were lung cancer (31.6%) . Abdomen and chest were the most common metastatic lesions, unless face and back metastasis was less common. The avarage time of the appearance of the skin lesions after detection of the primary tumors was 28.7 months. The avarage time of death after the appearance of skin metastasis was 6.9 months. When metastatic skin cancers in nasal area are found, we had better to speculate the presense of kidney cancer first, and secondarily the presence of lung cancer as primary cancers.
