- Abstract
An otherwise healthy 20-year-old Caucasian woman presented with small flat papules (1-3 mm in diameter) showing a hyperkeratotic and desquamative rim and a slightly depressed center, located exclusively on the nose (Fig. Discussion Porokeratosis (PK) was first described by Mibelli in 1893 and is thought to be a disorder of keratinization, but the definitive pathogenesis remains unclear. It has been proposed that PK is caused by a proliferation of abnormal clones of epidermal cells, and multiple genetic loci have been associated with PK.
