[Chewing pads, a variant of knuckle pads].

Three young male patients with chewing pads are reported. Their tic-like habit of chewing on the dorsal aspects over the middle joints of fingers I-IV caused a pad-like thickening of soft tissue. These chewing pads are a variant of "false" knuckle pads. The importance of a medical history and dermatological inspection is stressed to avoid unnecessary diagnostic procedures. This harmless augmentation of soft tissue is commonly confused with rheumatoid disease of the fingers, sarcoidosis or pachydermoperiostosis. Patients should be informed of the true nature of their pads, as discontinuation of their chewing habit will resolve their problems.
