Images in Clinical Urology Penoscrotal Mass: A Rare Presentation of Herpes Simplex Virus Infection Ryan C. Owen, Laurentia Nodit, Paul Hatcher, Wesley White, and Frederick Klein A 55-year-old man presents with a 10-cm condylomatous penoscrotal mass. Final pathology after surgical removal reveals a rare vegetative lesion with underlying herpes simplex virus infection. Along with neoplasia, infectious causes must remain in the differential diagnosis in the immunocompromised patient who presents with an atypical lesion.

55-year-old man presents with a 10-cm condylomatous penoscrotal mass. He reports no prior exposure to sexually transmitted disease, and human immunodeficiency virus infection status is unknown as the patient refuses follow-up. Final pathology after partial penectomy and scrotectomy reveals a rare vegetative lesion, which stains positive with immunoperoxidase studies for both Herpes simplex virus (HSV) 1 and 2. This patient demonstrates an atypical presentation of HSV infection, which may pose a clinical diagnostic challenge. HSV infection is ubiquitous and typically Financial Disclosure: The authors declare that they have no relevant financial interests.

presents as clustered vesicles, erosions, or ulcerations on an erythematous base with a recurrent or relapsing pattern. Less known, HSV infection can produce a persistent nodular exophytic growth (Fig. 1) predominantly in human immunodeficiency virusepositive patients,1 as well as in other immunosuppressed patients such as transplant recipients,2 common variable immunodeficiency,3 or lymphoproliferative disorders. Due to persistent tumor-like reaction, the exophytic condylomatous presentation of HSV infection raises diagnostic difficulties regarding discrimination between neoplasia and infection with concomitant vegetative herpes infection and squamous cell carcinoma described in the literature (Figs. 2-3).4 Oral or intravenous antiviral regimens are efficacious for large vegetative lesions1,5,6; however, surgical excision with epidermal denervation offers the potential for eradication.5,7 http://dx.doi.org/10.1016/j.urology.2014.07.020 0090-4295/14
