Overview
Knuckle pads (also known as "Heloderma", meaning similar to the skin of the Gila monster lizard for which it is named) are circumscribed, keratotic, fibrous growths over the dorsa of the interphalangeal joints.[1] Knuckle pads are well-defined, round, plaque-like, fibrous thickening that may develop at any age, and grow to be 10 to 15mm in diameter in the course of a few weeks or months, then persist permanently.[2]:604 Knuckle pads are sometimes associated with Dupuytren's contracture and camptodactyly[2]:604, and histologically, the lesions are fibromas.[2]:605
