Posthitis: a rare localization of atopic dermatitis.

Abstract

Case 1. An 8-year-old boy had a history of inflammatory, itchy lesions persisting for a year on the foreskin. His family history revealed seasonal allergic rhinitis in the mother and his personal history mild atopic dermatitis in classic sites with manifestations recurring only in spring. The physical examination (Fig. 1) revealed erythema and rhagades of the foreskin and scaling of the penis. The laboratory examinations were within normal limits. The final diagnosis was atopic posthitis and topical corticosteroids were prescribed.
Case 2. An 8-year-old boy had a family history of atopic dermatitis and allergic rhinitis, and also atopic personal history (asthma). From 8 months he presented persistent, itchy lesions on the foreskin and the physical examination (Fig. 2) revealed on the end portion of the foreskin erythema and erosion, leading to the final diagnosis of atopic posthitis.
