Lupus tumidus is considered a rare subtype of chronic cutaneous lupus
erythematosus, characterized by erythema and bright urticarial
erythematous-violaceous lesions that leave no scars after regression.
Histopathology reveals perivascular and periannexal lymphohistiocytic
infiltrates in the papillary and reticular dermis and interstitial mucin
deposition. Treatment is based on photoprotection, topical corticosteroids and
antimalarials. We report two cases of lupus tumidus, which deserve attention for
their low frequency in the literature, in addition to their relevance as a
differential diagnosis among dermatologic disorders.
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.
