Bronchogenic carcinoma mimicking paronychia and osteomyelitis in the great toe.

Abstract

Bone metastases from malignant tumors are common, but metastatic lesions to the bones of the foot are very rare. The most common primary lesion is the genitourinary tract, and the tarsal bones are most commonly involved. We present a rare case of squamous cell carcinoma of the lung, metastatic to the right great toe, that presented clinically as paronychia and osteomyelitis. This was the primary manifestation of an occult and disseminated disease.
