Metastasis of squamous-cell carcinoma of the lung to the first web space of the hand

Abstract

While primary squamous-cell carcinoma of the hand is common, metastasis of a squamous-cell carcinoma to the hand is very rare. It has been reported to arise from carcinoma of the lung and oesophagus and, rarely, from other tumours. We describe a patient with metastatic squamous-cell carcinoma occurring in the first web space of the hand from primary lung cancer, which remained undetected for 30 months after treatment of the metastasis.
