Generalized annular lichen planus with a unique morphology in a patient seropositive for HIV

Human immunodeficiency virus (HIV) infection is often associated with an array of skin manifestations, which are frequently more severe and present more atypically than those observed in nonHIV-infected persons. Some of them are acquired immune deficiency syndrome (AIDS) defining, and those such as seborrheic dermatitis, dermatophytosis, herpes simplex, and psoriasis may present in an exaggerated manner.1 Lichen planus (LP) is a common inflammatory dermatosis of unknown origin that presents in a variety of morphologic patterns. Many clinical variants, such as atrophic, hypertrophic, eruptive, linear, and annular, have been described in literature.2 Annular LP (ALP) is often considered one of the rare clinical forms. Various authors report that approximately 7% to 10% of LP lesions may have an annular morphology.3 Here, we report a case of generalized ALP unique in morphology in a patient with HIV infection.
