Metastatic Skin Carcinoma / 日本農村医学会雑誌

ABSTRACT

We reported nine cases of metastatic skin carcinoma experienced at the Department of Dermatology, Obihiro Kosei Hospital during the period from April 1991 to March 1993. Lung was the most common primary lesion (four out of nine cases), followed by uterus (two) and stomach, breast, and kidney (one each). The clinical features of the metastases were classified into nodular (five cases), inflammatory (one case) and sclerotic (three cases) types. Peculiar zoster-like inflammation was seen in metastatic gastric cancer. Pathologically, adenocarcinoma was more common than squamous cell carcinoma. The average interval between the diagnosis of the primary cancers and the development of the skin metastases was about 30±25 months. The average life span after the detection of the skin metastases was 6.8±5.6 months. Poor prognosis of skin metastasis was thus reconfirmed.
