A Case of Alopecia Areata in a Patient with Type I Pityriasis Rubra Pilaris / 대한피부과학회지

ABSTRACT

There have been a few cases of alopecia areata (AA) patients with pityriasis rubra pilaris (PRP), but the relationship between them is unclear. To the best of our knowledge, there have been no cases of co-occurrence reported in Korea. A 58-year-old male presented with multiple erythematous follicular papules and scaly plaques on the both legs with diffuse keratotic thickening on both palms and soles for several months. After skin biopsy, he was diagnosed with type I PRP. After treatment with oral and topical steroid, vitamin D3 analogue, oral alitretinoin, and urea cream for one week, multiple, diffuse alopecic patches appeared. He was diagnosed with AA after skin biopsy and we added topical minoxidil. Herein, we report a case of AA in a patient with type I PRP.
