Ulerythema Ophryogenes, a Rare and Often Misdiagnosed Syndrome: Analysis of an Idiopathic Case

Abstract

Keratosis pilaris (KP) is a follicular hyperkeratosis disorder which is frequently detected in the adult population (44%), mostly in female adolescents (80%). It is a genetic autodominant dermatosis with variable penetrance, but no specific gene association has been determined, even though association to the presence of chromosome 18p deletion has been reported in some cases. We report the case of a 51-year-old Caucasian woman affected by keratosis pilaris gradually progressing with age and with a story of multiple abortions. Standard karyotype and CGH array analyses did not reveal any genetic abnormality. Virological analyses detected the presence of HPV 36 DNA inside the dorsum biopsy, leading to hypothesize its involvement in the evolution of the lesion. Clinical history and patient examination led the diagnosis of an idiopathic case of Ulerythema ophryogenes. The analysis of more cases could be useful to verify the involvement of cutaneous HPV in the progression of the clinical manifestation of the KP variants.
