RESUMEN
Anogenital herpes simplex virus (HSV) infection can rarely manifest as a pseudotumor, which some have termed "hypertrophic herpes." Almost all cases are in immunocompromised patients, typically with human immunodeficiency virus/acquired immune deficiency syndrome. This presentation often mimics malignancy clinically. We present a case of cervical HSV pseudotumor with associated lymphadenopathy in an immunocompetent woman, mimicking locally advanced cervical cancer. The lesion resolved with acyclovir therapy. We emphasize that (1) clinically suspected malignancy must be confirmed by pathologic examination; (2) infectious mimics must be considered when microscopic examination fails to confirm a clinically suspected anogenital malignancy, particularly in patients with compromised or unknown immune status; (3) morphologic hallmarks of infection may be focal; (4) co-infection with multiple sexually transmitted infections can occur, particularly in immunocompromised patients, and HSV or other infection does not per se exclude concurrent human papillomavirus-associated neoplasia; and (5) anogenital HSV pseudotumor should prompt clinical evaluation for human immunodeficiency virus or other immunosuppression.
