Thumb talc granuloma mimicking squamous cell carcinoma: A case report.

Application of topical powdery substances to the wound is an age old practice. Talc containing powdery substances are however commonplace and predominant in our environment. This insoluble mineral has been linked to chronic granulomatous reaction particularly in the lungs. We present a case report of a fifty-year-old man with prolonged application of talc containing powdery substances to the left thumb wound and excitation of exuberant granuloma mimicking squamous cell carcinoma. He had complete excision of the mass and satisfactory first dorsal metacarpal artery flap coverage of the soft tissue defect.
