[Two cases of herpes simplex esophagitis during treatment for lung cancer].
Herpes simplex virus (HSV) is one of the three major causes of infectious esophagitis, along with Candida albicans and Cytomegalo virus (CMV). Most cases occur in immunocompromised hosts, in whom this can be life threatening. We report two cases of herpes simplex esophagitis occurring during treatment for lung cancer. Case 1: An 80-year-old man with radiation pneumonia caused by radiotherapy for lung cancer was admitted for treatment with antibiotics and corticosteroids. Shortly after initiation of treatment, he complained of dysphasia. Endoscopic examination revealed herpes simplex esophagitis. Case 2: A 71-year-old man was given corticosteroids for cryptogenic organizing pneumonia following chemotherapy for lung cancer. During treatment, the patient complained of odynophagia. Endoscopic examination revealed herpes simplex esophagitis. Both cases died due to progression of lung cancer and acute respiratory distress syndrome, despite administration of acyclovir. When immunocompromised patients complain of prolonged dysphagia and odynophagia, the presence of herpes simplex esophagitis should be clarified by endoscopic examination. It is occasionally difficult to distinguish between HSV and Candida esophagitis by endoscopic observation alone. Esophageal mucosal endoscopic cytology can help differentiate between these three infectious agents.
