Visceral dissemination of herpes zoster with multiple ulcers in the upper gastrointestinal tract of an apparently immunocompetent patient.

Visceral dissemination of varicella zoster virus (VZV) may follow cutaneous infection in immunocompromized patients (e.g. bone marrow transplant recipients) [1]. However, involvement of the upper gastrointestinal tract is rare [1–4]. An 81-year-old man underwent upper endoscopy for heartburn, nausea, and vomiting. There was no prior history of clinically overt immunodeficiency. Endoscopy revealed multiple small, superficial ulcers in the esophagus, the gastric corpus and antrum, and the duodenum (●" Fig.1 a– c). A few days prior to endoscopic evaluation, the patient had developed a few vesicular eruptions over his head and trunk (●" Fig.1d). Histological examination of the biopsy specimens revealed acantholysis and ballooning of keratinocytes in the esophagus (●" Fig.2a). Gastric and duodenal ulcerations were surrounded by a prominent histiocytic infiltrate. Epithelial and stromal cells showed viral cytopathic changes including enlarged hyperchromatic nuclei with uneven borders. Nuclei appeared molded with chromatin margination and a “ground glass” appearance. Single viral inclusions were present (●" Fig.2b). Polymerase chain reaction of samples from esophageal and gastric biopsies showed positive amplification of VZV DNA (44 kDa protein gene). The patient improved considerably after the initiation of treatment with acyclovir 10mg/kg three times daily for 10 days. Multifocal gastrointestinal involvement with VZV following cutaneous dissemination is uncommon even in immunocompromized hosts, and has not been reported in apparently immunocompetent patients up to now [1]. After initial infection has occurred, the virus enters a latent stage in the dorsal root ganglia [1]. Posterior sensory nerve roots contain nerve fibers from both the skin and the inner organs [1,5]. Reactivation of latent VZV may thus lead to a centrifugal spread toward the skin, as well as a centripetal spread towards the visceral organs [1,5]. The present case illustrates the potential visceral dissemination of herpes zoster, causing multiple ulcers throughout the upper gastrointestinal tract of an apparently immunocompetent individual.
