A Case of Metastatic Squamous Cell Carcinoma of the Skin Following a Pleural Needle Biopsy / 대한피부과학회지

ABSTRACT

The mechanisms of cutaneous metastases in internal malignant tumor are direct invasion, lymphatic spread, hamatologic dissemination and incidental inoculation in operation. Also, the diagnostic procedure such as percutaneous biopsy of internal tumor is another possible mechanism. A 73-year-old man presented with a solitary erythematous nodule on the right upper chest for 2 months. He has been treated for squamous lung carcinoma for 1 year. 2 months ago, pleural biopsy for pleural metastasis was done at the same site on the chest. Histopathologic examination of the nodule showed cutaneous metastasis of lung cancer around the dissected dermis which had been made by a needle in pleural biopsy.
