Benign Atrophic Papulosis (Degos Disease) With Lymphocytic Vasculitis and Lichen Sclerosus-Like Features.

Degos disease manifests as 2 distinct clinical variants, malignant atrophic papulosis and benign atrophic papulosis, which are distinguished by the presence or absence of systemic disease. Both forms feature cutaneous involvement typified by erythematous papules with scar-like centers, and the classic histologic picture is described as wedge-shaped dermal necrosis overlying thrombotic vasculopathy. However, the histopathology of early lesions is distinct and more variable. A case of benign atrophic papulosis with lymphocytic vasculitis and lichen sclerosus-like features is described, and the spectrum of histologic findings in Degos disease is reviewed.
