Lupus erythematosus tumidus with discoid lupus erythematosus-induced alopecia of the scalp.
Lupus erythematosus tumidus (LET) is an uncommon variant of cutaneous lupus erythematosus. Lupus erythematodes tumidus is characterized by smooth, erythematous plaques on sun-exposed areas without surface changes, such as follicular plugs, atrophy, or scale. Histopathologic features include a lymphocytic, perivascular and periadnexal infiltrate with abundant interstitial, superficial, and deep dermal mucin without appreciable epidermal and vacuolar changes. Typically, LET is responsive to treatment with systemic antimalarials. We present a unique case of alopecia associated with LET, which was partially responsive to hydroxychloroquine. We also note that the plaque of LET is adjacent to the plaque of discoid lupus erythematosus.
