title: [Cutaneous metastasis from lung adenocarcinoma resected 34 months before surviving 5-year after skin tumor resection without relapse].
abstract: A 79-year-old man complained incurable skin ulcer that was treated in the neighborhood hospital during 2 months. He had been undergone right upper lobectomy for the lung adenocarcinoma in our hospital 34 months ago. The skin lesion in the right axilla was an elastic hard tumor about 2 cm large in thesubcutaneous tissue with ulceration, and was diagnosed as adenocarcinoma by cytology. Fluorodeoxy glucose-positron emission tomography (FDG-PET) /computed tomography (CT) showed no metastatic lesion other than the skin tumor, and the tumor was resected with a margin. Immunohistochemistry [cytokeratin (CK)-7(+++), CK-20(-), thyroid transcription factor (TTF)-1(-)] indicated the skin tumor to be metastasis from lung adenocarcinoma. He is alive over 8 years after right upper lobectomy(RUL)and 5 years after skin tumor resection without relapse.
