Prurigo pigmentosa (PP) is an inflammatory skin disease of unknown origin. The skin lesions in PP are symmetrically distributed on the back, chest, and neck. Pruritus is a prominent feature in many cases. We report on a 13-year-old girl with lesions typical of PP in a segmental arrangement on her left chest. A segmental distribution of PP has not been previously reported.
Henoch-Schönlein purpura (HSP) is the most common type of vasculitis in children. It usually presents as an acute onset of palpable purpura, mainly located on the lower extremities. Systemic involvement is very frequent, and complications may occur. An accurate diagnosis with skin biopsy showing leukocytoclastic vasculitis and IgA deposits is much recommended. Most cases will be managed conservatively with rest and oral NSAIDs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
