title: Granular parakeratotic acanthoma.
abstract: Granular parakeratosis was originally described as a dermatosis confined to the axillae that histopathologically shows characteristic findings in the cornified layer consisting of parakeratotic corneocytes housing keratohyaline granules. Since the original description of this entity, non-intertriginous examples and even incidental foci of granular parakeratotic corneocytes in association with other dermatoses have been recognized. This report details the findings of a previously unreported entity that we are naming granular parakeratotic acanthoma, which is fundamentally akin to acantholytic dyskeratotic acanthoma and epidermolytic acanthoma (ie, a solitary keratosis that histopathologically displays features indicated in its name).
