title: Histologic features of cutaneous lupus erythematosus.
abstract: Histologic examination of lesions plays a key role in the diagnostics of cutaneous lupus erythematosus (LE). LE has a broad spectrum of histopathological signs, which are related to the stages of the lesions. In addition to the main subtypes of LE, we report on special manifestations like Rowell's-syndrome and Chilblain LE, and give an account of Kikuchi-Fujimoto disease (histiocytic necrotizing lymphadenitis), which may be associated with systemic LE. Furthermore the most considerable histopathologic differential diagnoses are discussed.
