Cytomegalovirus oesophagitis following treatment with fludarabine for refractory lymphoplasmacytic lymphoma.

A 64-year-old man with a 2-week history of fatigue and fever presented to the medical admissions unit. He had a background of lymphoplasmacytic lymphoma and had recently completed a course of fludarabine-based chemotherapy. CT of the abdomen demonstrated an increase in spleen size and it was thought that his fevers were most likely due to disease recurrence or high-grade transformation. A bone marrow trephine was organised, which showed no evidence of lymphoma and positron emission tomography-CT demonstrated an area of increased avidity at the gastro-oesophageal junction. An oesophagogastroduodenoscopy was recommended, which revealed ulceration within the oesophagus and stomach. Biopsy of the lesions and immunohistochemistry confirmed a diagnosis of cytomegalovirus oesophagitis. He was treated with intravenous ganciclovir followed by oral valganciclovir for a total of 3 weeks. His fever resolved and he was discharged home approximately 8 weeks after he first presented.
