Abstract

Cutaneous metastasis originating from lung cancer is relatively rare and accounts for only 0.5~6.7% of of lung cancer metastases. In general, there is a histomorphologic resemblance between primary carcinoma and cutaneous metastatic carcinoma. A 45-year-old woman presented with a painless 0.8 cm erythematous nodule on her left shoulder. During the past 3 years, she had been receiving chemotherapy for the treatment of lung adenocarcinoma with bone metastases. A histopathological examination of the skin lesion showed adenocarcinoma and squamous cell carcinoma components, which were compatible with adenosquamous carcinoma. Herein, we report an interesting case of adenosquamous carcinoma showing cutaneous metastasis, which is a different pathologic subtype from primary lung adenocarcinoma.
