Pityriasis rubra Pilaris is a rare, chronic, mildly inflammatory disease characterized by fine acuminate follicular papules, erytheme, scaling of the skin, and recurrent spontaneous remissions and exacerbatioris. A 19 years old Korean girl presented the clinical symptoms of generalized Pityriasis rubra pilaris, the diagnosis of which was subsequently confirmed by histopathological examination. While associated systemic diseases were absent, some rather dramatic bone changes were observed. These bone changes, similar to those associated with hypervitaminosis-A, included halux valgus, clawed hands and toes, and bone marrow thinning due to the concentric resorption of metacarpal, metatarsal, and phalangeal bones. These bone changes were suspected to be the result of a chronic low-grade bone infection secondany to multiple skin fis?@Pityriasis rubra Pilaris is a rare, chronic, mildly inflammatory disease characterized by fine acuminate follicular papules, erytheme, scaling of the skin, and recurrent spontaneous remissions and exacerbatioris.
