Abstract

Abstract: Genital herpes simplex virus (HSV) infection in a human immunodeficiency virus (HIV) patient can present as a vegetative nodule. Clinical differential diagnoses of the nodule include condyloma latum, condyloma acuminatum, viral or fungal infection, and cutaneous neoplasms. Histological examination of herpetic nodules has been reported to show thick pseudoepitheliomatous hyperplasia with dense dermal lymphoplasmacytic infiltrate and multifocal multinucleated cells with herpetic viral cytopathic changes. We report two patients with HIV presenting with vegetative tumor‐like HSV nodules with distinctive histopathologic pattern of inflammation that has not been described in the literature before. All samples displayed slightly acanthotic epidermis with focal ulceration, dense dermal sclerosis, scattered plasma cells, and a brisk lymphoeosinophilic infiltrate found dissecting between dense collagen bundles. This pattern of inflammation is an important clue that can guide the pathologist to look for focal herpetic viral changes in the epidermis, as patients with HIV possibly tend to amount a predominantly eosinophilic immune response in inflammatory skin conditions.
