Epidermotropic metastasis of primary lung adenocarcinoma.

ABSTRACT

Cutaneous metastasis of lung cancer is a rare event and usually portends a grim prognosis. Several cases of lung cancer with cutaneous metastasis have been reported, but these have been largely limited to the dermis. Here we describe a unique case of cutaneous metastatic lung adenocarcinoma largely limited to the epidermis, mimicking Paget's disease or a cutaneous adnexal tumor.
