Digital papular calcific elastosis (DPCE), which is an acquired, marginal, papular acrokeratoderma that predominantly affects the radial side of the index finger, first web space, and ulnar side of the thumb, occurs in the middle-aged and elderly. In 1960, Burks et al1 first described in detail the clinical and histological features in 5 cases of DPCE, which they termed degenerative collagenous plaques of the hands. The condition was named DPCE in 1990 after a comprehensive study of 20 patients showed that this was a more accurate, descriptive term for the clinical and histological features.2 There is controversy regarding the role of UV light and pressure in the pathogenesis of DPCE. We report 3 unique cases of DPCE and discuss the incidence of DPCE in professional drivers and indoor workers.
