Idiopathic giant esophageal ulcers in a renal transplant patient responsive to steroid therapy.

Idiopathic giant esophageal ulcers in immunocompromised patients have been described only in patients with acquired immunodeficiency syndrome. A solitary report of an idiopathic giant esophageal ulcer in an immunocompetent patient exists. We describe a case of idiopathic esophageal ulceration ultimately responsive to steroid therapy in a 31-year old immunosuppressed, human immunodeficiency virus-negative renal transplant patient. The case is described with particular reference to the evaluation, differential diagnosis, and therapeutic response to steroids. Similarities in presentation and treatment to giant esophageal ulcers in human immunodeficiency virus infection suggest an underlying immune defect as the likely cause. This is the first described case of giant esophageal ulceration responsive to steroids in an immunosuppressed human immunodeficiency virus-negative patient. This entity should be added to the differential diagnosis of esophageal ulceration in solid organ transplant recipients.
