Histologic features included mild epidermal acanthosis and hyperkeratosis. In the dermis, collagen bundles were arranged haphazardly, many in a vertical pattern. There was a general basophilic tint to the dermal tissue. On higher power, masses of basophilic elastotic tissue were visualized. The elastic tissue stain confirmed the presence of these elastotic masses.
The condition now known as collagenous and elastotic marginal plaques of the hands was first described in 5 patients in 1960 by Burks et al,1 who called it degenerative collagenous plaques of the hands. Since then, other reports have been published, and several alternative terms have been introduced. The term keratoelastoidosis marginalis of the hands was proposed in 1965, suggesting a similarity to the hereditary condition known as acrokeratoelastoidosis of Costa.2 In 1981, Rahbari3 described the difference between these entities. Then, in 1990, the term digital papular calcific elastosis was used to describe the condition in a series of 20 patients.4 The term collagenous and elastotic marginal plaques of the hands has since become the accepted name.5-7
