| Summary: | Knuckle pads are under reported benign well-defined thickened skin plaques usually overlying the extensor aspect of the small joints of the hands. Primary knuckle pads are a fibromatous disease that may be seen in several inherited fibromatosis and keratoderma syndromes. Secondary knuckle pads are distinctly different from primary knuckle pads, acquired by repetitive trauma, and dermoscopy may aid in diagnosis. We hereby report a case of a female patient with recalcitrant knuckle pads for 8 years, that were confused with psoriasis or erythrokeratoderma. However, after repeated consultations, they were found to be due to body-focused repetitive behaviour of recurrent skin biting, denoting dermatodaxia. After the condition was explained, the patient consciously refrained from biting her knuckles with improvement within a few weeks. |
