Lung Tumor Skin Metastasis: Case Report of a Solitary Cutaneous Ulcerated Lesion as Initial Manifestation of Lung Carcinoma.

Lung cancer has the highest cancer incidence, and it is the most common cause of cancer death worldwide. Cutaneous metastases are infrequent compared to hilar nodes, adrenal glands, liver, brain, and bones. However, unusual skin lesions in patients at high risk of lung cancer should be regarded carefully to rule out a metastatic manifestation of an occult primary site tumor. Surgical excision, or incisional biopsy when the former is deemed unfeasible, should be performed to allow histopathological examination in case of occult primary site. In patients affected by advanced lung tumors, surgical excision could be beneficial in terms of pain control and improvement of the quality of life. We report a case of a solitary large skin lesion as an early manifestation of a lung adenocarcinoma.
