localized (eg, facial/hand), airborne, and generalized dermatitis, and may also complicate atopic and stasis dermatitis, or result in nummulardermatitis. Seborrheic-, rosacea- and impetigo-like dermatitis have recently been reported. For a correct diagnosis, FA 2% aq. (0.60 mg/cm ) should be used, and particularly the FRs bronopol 0.5% pet. and diazolidinyl urea 2% pet. should be patch tested separately

), pityriasis rosea (PR), and nummulardermatitis (ND) that mostly involve the trunk. The study included 150 cases (PP:50, LP:30, MF:20, PR:30, ND:20). The lesions were inspected using a polarized dermoscope. The dermoscopic findings of each lesion were evaluated for background color, type, and distribution of vessels, color and distribution of scales, and other additional findings.

-eosin-stained sections obtained from 96 patients diagnosed with PP, HE, or HHD. The patients were divided into 4 subgroups: PP (n = 16, group A), HE without atopic or nummulardermatitis (n = 41, group B), HE with atopic or nummulardermatitis (n = 14, group C), and HHD (n = 25, group D). Loss of the granular layer (group A 62.5%, group B 24.4%, group C 0%) was more consistent with a diagnosis of PP
