Pulmonary metastases: A rare manifestation of the most common cancer

Abstract

Basal cell carcinoma (BCC) is the most common human malignancy but rarely metastasises. We report on two patients with symptomatic lung metastases and a past history of recurrent BCC excisions.

Our second patient, a young never-smoker with two previous BCC, was confirmed as having a pulmonary metastasis from BCC on the lung resection specimen. Pulmonary metastasis from an unidentified primary site is a common clinical situation. These patient..
