title: Wong-type dermatomyositis: a mimic of many dermatoses.
abstract: Wong-type dermatomyositis (DM) is a rare variant characterized by keratotic follicular papules that may mimic pityriasis rubra pilaris. Histopathologic examination shows follicular and non-follicular epidermal invaginations filled with keratin. The diagnosis is often delayed. Twenty-four cases of Wong-type DM have been reported thus far in the literature. Herein, we report the clinical and histopathologic findings of three additional cases in order to raise awareness of the disorder.
