Keratoelastoidosis marginalis: a case report and review of literature

Marginal keratodermas are broadly classified into acquired and familial forms. Keratoelastoidosis marginalis, also known as digital papular calcific elastosis, is an acquired, marginal, acrokeratoderma that predominantly affects the radial side of the index finger, first web space, and ulnar side of the thumb. It occurs in the middle-aged and elderly. Prolonged UV exposure and repeated trauma to the hands seem to be the etiological factors, although their role has not been well defined in the pathogenesis of keratoelastoidosis marginalis. We report a case of keratoelastoidosis marginalis in a 60-year-old woman.
