Pemphigus vulgaris and lichen planus pigmentosus in an HIV-positive patient.

Pemphigus vulgaris is a rare autoimmune blistering disorder which can occur with other disorder with autoimmune etiology like lichen planus pigmentosus. The concurrence of pemphigus vulgaris and HIV infection has been rarely reported in literature. Here we report a 31 year old patient who came with oral and skin erosions suggestive of pemphigus vulgaris and later developed HIV infection with lichen planus pigmentosus.
