Abstract

Granular parakeratosis is an unusual acquired dermatosis characterized by intertriginous keratotic papules. Histologic examination shows parakeratosis with large numbers of basophilic keratohyaline granules within the stratum corneum. We report a case of a granular parakeratosis of the axilla that cleared rapidly with topical administration of tretinoin.
