[Atrophic pilar keratosis of the face: case report]

Keratosis pilaris atrophicans faciei (KPAF), previously called ulerythema ophryogenes, belongs to a group of follicular syndromes with inflammation and atrophy. The disease often starts at birth or during the first months of life with autosomal dominant inheritance.

We report a case of a 24-year-old woman, who noticed the first lesion two years ago. Skin lesion spread symmetrically on the cheeks, forehead and chin. Keratotic follicular papules were surrounded by erythema. After disappearance of follicular papules, atrophy occurred. Histopathological analysis from skin biopsy specimens confirmed the diagnosis of KPAF.

Follicular syndrome with inflammation and atrophy starts in early childhood, but first lesions can also appear among teenagers or in adults. The course of the disease is progressive with permanent follicular destruction. The histopathologic changes are dynamic and follow the clinical course of the disease. A topical retinoid: tretinoin therapy was introduced. After one month of treatment good effects were visible, including decrease of erythema and follicular hyperkeratosis.
