Lichen aureus with pseudolymphomatous infiltrate


Kolm, Isabel; Buset, Caroline; Flury, Ursula; Nosek, Daniel; Kazakov, Dmitry V; Kempf, Werner (2021). Lichen aureus with pseudolymphomatous infiltrate. Journal of Cutaneous Pathology, 48(5):669-673.

Abstract

Lichen aureus is a variant of pigmented purpuric dermatoses. The usual histopathology of lichen aureus is characterized by a subepidermal dense, band-like lymphocytic infiltrate, extravasated erythrocytes, and hemosiderin deposits. We report three patients with lichen aureus on the extremities with similar clinical, dermoscopic, and histopathological findings characterized by a dense band-like relatively deep dermal infiltrate accompanied by extravasation of erythrocytes and hemosiderin deposits occasioning a resemblance to a lymphoproliferative disorder.

Keywords: lichen aureus; mycosis fungoides; pigmented purpuric dermatosis; pseudolymphoma.
