Darier disease is an autosomal dominant dermatosis caused by the mutation of the ATP2A2 gene. There are rarer clinical variants showing atypical skin lesions like the hypertrophic, vesicobollous, hypopigmented, and comedonal subtypes. We present the case of a 28-years-old healthy man with more than hundred pruritic open comedone-like hyperkeratotic dark papules of the upper and lower back. Histological examination showed dilated follicular infundibulum, containing keratotic material, suprabasal acantholysis and dyskeratotic cells compatible with comedonal Darier disease. There are less than 10 published cases of this clinical and histological subtype.
