The clinical and histopathological features of cutaneous herpes simplex virus (HSV) infection have been well described. Genital herpetic infections are largely induced by HSV type 2, but 30% of cases can be caused by HSV type 1. Immunocompromised patients are known to exhibit atypical patterns of clinical presentation with variable lesion morphology and anatomic location. A subset of patients may show morphology such as nodules or verrucous lesions. Analogously, some biopsy specimens may show unusual microscopical features, such as a lack of keratinocyte cytopathology, lymphocyte infiltration or vasculopathic changes that are expected irrespective of the patient's immune status. We present the case of a patient carrying a previous diagnosis of pemphigus vulgaris, status posttreatment with methotrexate and prednisone, who developed a perineal ulcer exhibiting significant numbers of plasma cells, many of which were cytologically atypical. This morphology was suggestive of a hematopoietic malignancy. Immunoperoxidase staining for HSV decorated a focal collection of keratinocytes that lacked appreciable viral changes expected of HSV infection.

To report recurrent conjunctivitis and scleritis secondary to coexistent conjunctival pemiphigus vulgaris and cryptic herpes simplex infection.. Case report.. Retrospective review.. A 54-year-old woman presented with recurrent left eye irritation and redness. Four years earlier, she was diagnosed (biopsy) with cutaneous pemphigus vulgaris requiring immunomodulatory therapies. She was receiving oral acyclovir for recurrent genital herpes and intravenous immunoglobulin for pemphigus. Examination revealed unilateral necrotizing scleritis and conjunctivitis. Immunohistochemical staining of biopsies demonstrated conjunctival pemphigus and herpes in conjunctiva and sclera. Valacyclovir therapy brought resolution.. Cryptic ocular herpes may confound matters in someone with an autoimmune disease thought to be the sole source of ocular inflammation. Immunohistochemical analysis can resolve the mystery.
