Management of cytomegalovirus reactivation in patient with immunotherapy-induced gastritis.

We present the case of a 52-year-old woman diagnosed with stage IV clear cell renal cell carcinoma who received combination of surgery and systemic therapy with nivolumab (anti-PD1) and ipilimumab (anti-CTLA-4). During treatment, patient presented oral intolerance, vomiting and abdominal pain. Computed tomography (CT) and gastroscopy (EGD) were performed, identifying findings suggestive of severe gastro-duodenitis with friability and diffuse oedema of the mucosa and deep ulcers.
