This nondescript necrotic lesion in an HIV-positive patient turned out to represent herpes infection.
Herpes infection, either simplex or zoster, can take on unusual appearances in the immunocompromised host.
Chronic ulcers, crusted or necrotic lesions are typical. Long, linear ulcers in body folds resembling the cut of a knife ("the knife-cut sign") may occur. The inguinal fold is a typical location for this [J Clin Aesthet Dermatol 2015;8;38].
See herpes simplex or zoster for appropriate treatment. Often, therapy must be prolonged in the immunocompromised host. Therapy is often continued until the lesions clear.
