Collagenous and elastotic marginal plaques of the hands is an acquired dermatosis affecting predominantly the radial aspect of the index finger, first web space and ulnar aspect of the thumb on the dominant hand. A combination of chronic photodamage and repetitive mechanical trauma is thought to be responsible. Histologically haphazardly arranged thickened collagen bundles, basophilic elastotic material and calcium deposits are found.
