# Sulfasalazine-Induced Epstein–Barr Virus-Positive Mucocutaneous Ulcer

## TL;DR

This paper reports a rare case of an Epstein-Barr virus-related skin ulcer possibly caused by the drug sulfasalazine.

## Contribution

The paper introduces sulfasalazine as a potential trigger for EBV-positive mucocutaneous ulcers.

## Key findings

- EBV-positive mucocutaneous ulcers are a rare manifestation of EBV-driven lymphoproliferative disorders.
- Sulfasalazine may contribute to the development of such ulcers in some patients.
- The case highlights the need for awareness of EBV reactivation in immunomodulated settings.

## Abstract

Epstein–Barr virus (EBV) may cause a wide spectrum of symptomatology in humans ranging from asymptomatic upper respiratory tract infection to infectious mononucleosis and in more severe cases lymphoproliferative disorders or hemophagocytic lymphohistiocytosis. Its neoplastic potential is higher in immunocompromised individuals. We describe a case of EBV-positive mucocutaneous ulcer, a more indolent clinical entity on the spectrum of EBV-driven lymphoproliferative disorders, and are one of the first to put sulfasalazine, an immunomodulatory agent, forward as the possible culprit.
