Lung cancer rarely metastasize to the skin, with an incidence of only 1.7% and 3.1%. However, the presence of cutaneous metastasis as the first sign of a clinically silent lung cancer is exceedingly rare. We report a case of an 80-year-old male with an metastatic carcinoma of the scalp originating from lung cancer which was found later than the cutaneous metastatic cancer. Painful, purulent indurated erythematous nodule measured 4 cm in greatest diameter was observed in the right temporal scalp, which resembles erysipelas. Biopsies demonstrated poorly differentiated carcinoma in the dermis. Immunohistochemically, Pan-CK, CK7 and TTF-1 was positive, while CK20 and P40 were negative. Chest X-ray and computed tomography scan revealed a neoplastic lesion in the right upper lung, multiple osteolytic bone lesions and enlarged LNs in right hilar. CT-guided lung biopsy revealed poorly differentiated adenocarcinoma. Although the most common features of metastatic skin lesions from lung cancers are firm nodules, some exceptional clinical features, including erysipelas-like, allergic contact dermatitis-like, and ulceration have been reported. It may be an important clue for undiagnosed malignancies. Therefore, dermatologists should be aware of these uncommon features of metastatic skin carcinoma, and biopsy should be performed from any suspicious skin lesions.
