Scalp Swelling a Rare Presentation of Disseminated Lung Carcinoma

Subcutaneous metastatic nodules are uncommon presentation of underlying malignancy. Cutaneous metastasis is seen in less than 4% cases of all malignancies and is usually seen following initial diagnosis. Lung carcinoma has higher predisposition for bony metastasis compared to other malignancies, however skull metastasis is rare. Cutaneous metastasis is seen in less than 15% cases of lung cancer. These lesions are mostly detected late after the diagnosis of primary tumour in later course of disease. However, an asymptomatic patient presenting with scalp swelling as initial presentation of underlying advances lung malignancy is rare, less than 20 such cases reported in literature till date. Our case is highlighting not only the rarity of such cases but also consider detail evaluation of any scalp swelling.
