Knuckle pads.
Knuckle pads are well circumscribed thickenings of the skin over the metacarpophalangeal and, more commonly, the proximal interphalangeal joints. Although the association with several other clinical syndromes including Dupuytren's disease is well documented, most cases are idiopathic. We present a case of knuckle pads and briefly review the history and course of this disease.

Knuckle pads occur from benign thickening of the skin, principally the epidermis, and are occasionally seen in children.

However, one study showed an inverse correlation between KC and metacarpophalangeal joint OA. METHODS We conducted a retrospective case-control study among persons aged 50 to 89 years who received a radiograph of the right hand during the last 5 years. Patients had radiographic...
متن کاملKnuckle pads – a rare finding
Knuckle pads are rare harmless subcutaneous nodules that must be differentiated from joint disease of the proximal interphalangeal or rarely of the metacarpophalangeal joints as well as from other masses of the paraarticular tissues. We present a case of an otherwise healthy 36-year-old woman presenting with bilateral knuckle pads located at the dorsal aspect of the proximal interphalangeal joi...
متن کاملFinger Knuckle Print Based Authentication
-In this paper, we investigate a new approach for personal authentication using Finger-Knuckle-Print through a novel texture descriptor, Local Directional Pattern (LDP). The image is encoded with Local Directional Pattern, which enhances the information as each pixel is represented as a binary LDP code. The Finger-Knuckle-Print is divided into smaller areas and LDP histograms are extracted from...
