Lupus tumidus: a report of two cases

Abstract: 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… Show more

“…Hypersensitivity to sun radiation is observed in this form of lupus -the highest among all CCLE types -that occurs in about 70% of LET-patients [2,4,8]. Characteristically, the time between the sun exposure and the appearance of skin lesions is relatively long, depending on the sources from 1 up to even 3 weeks, and consequently, patient often do not associate lesions with UV radiation [2,4,9]. Antimalarial drugs result in a fast improvement and disappearance of skin lesions, usually within a couple of weeks; the difference in efficacy of chloroquine and hydroxychloroquine was not confirmed [8,10].…”

“…W tej postaci tocznia obserwuje się wybitną nadwrażliwość na promieniowanie słoneczne, największą spośród wszystkich odmian CCLE, występującą u ok. 70% chorych z LET [2,4,8]. Charakterystyczne jest to, że czas pomiędzy ekspozycją na słońce a momentem pojawienia się zmian skórnych jest dość długi, w zależności od źródeł od 1 do nawet 3 tygodni, co często powoduje, że pacjenci nie wiążą wystąpienia wykwitów z promieniowaniem UV [2,4,9]. Leki przeciwmalaryczne powodują szybką poprawę i ustąpienie zmian skórnych, zwykle w ciągu kilku tygodni, przy czym nie stwierdza się różnicy w skuteczności pomiędzy chlorochiną a hydroksychlorochiną [8,10].…”
