A rare cause of dysphagia: herpes simplex esophagitis.

World J Gastroenterol 13(19):2756-7 (2007) PMID 17569149

Herpes simplex esophagitis (HSE) is well documented in immunosuppressed patients. However, it is rare in the immunocompetent host. We present a case of HSE in a 21 year-old healthy lady who was admitted to our unit with dysphagia, odynophagia and chest pain. Clinical examination revealed mild epigastric tenderness and admission bloods including full blood picture, electrolytes and inflammatory markers were normal. She underwent an esophagogastroduodenoscopy (EGD) which revealed severe exudative, well-circumscribed ulcerations in her distal esophagus. Biopsies confirmed severe esophagitis with acute ulceration and subsequent polymerase chain reaction (PCR) confirmed herpes simplex virus (HSV) type 1. Subsequent assessment failed to identify an immune disorder. HSE should be suspected when faced with characteristic endoscopic findings, even if the patient is immunocompetent. When the diagnosis of HSE is confirmed, an immune deficiency should be sought.
