In a recent review by Hapa et al., of 24 patients (ages 2–14, with a median age of 7 years) with pityriasis lichenoides, PLC was more common than PLEVA (62.5 % to 25 %, respectively), with features of both in a small subset of patients (2.5 %) [5•]. In contrast, a larger retrospective review of 124 patients in 2007 identified PLEVA in 57.3 Pityriasis Rosea is more common than Lichen Planus, affecting up to 1 in 100 people, especially those aged between 10 to 35 years.
