Cytomegalovirus-associated gastric ulcer in an immunosuppressed patient with pemphigus vulgaris.

A 79-year-old female with pemphigus vulgaris developed a cytomegalovirus (CMV)-associated gastric ulcer whilst on standard immunosupression with azathioprine and prednisolone. Following treatment with ganciclovir and ranitidine the ulcer healed. CMV infection frequently involves the gastrointestinal tract of immunocompromised patients causing inflammation, ulceration and haemorrhage. Although it has also been described in patients treated with immunosuppressive therapy for malignancy and other autoimmune disease, we are not aware of previous reports in patients treated for autoimmune bullous disease.
