A case of pigmented purpuric lichenoid dermatitis of Gougerot-Blum is presented and the pertinent literature is reviewed. This case is unusual in that the lesions were unilateral and very limited in extent. The patient presented with a localized pigmented purpuric eruption of plaques on the dorsum of one foot which mimicked Kaposi's sarcoma. However, a biopsy confirmed the diagnosis of pigmented purpuric lichenoid dermatitis of Gougerot-Blum.
