[Candida esophagitis and cytomegalovirus gastritis: optic and immunohistochemical diagnosis in an HIV+ patient].

Esophageal candidiasis, along with gastritis caused by cytomegalovirus--CMV--, is a common opportunistic infection in immunodepressed patients. A clinico-pathological description is made of a human immunodeficiency virus-positive female (group IV-C-2) with a history of odynophagia and dysphagia resistant to treatment. The light microscopy and immunohistochemical study of an endoscopic esophago-gastric biopsy allowed the diagnosis of moniliasic esophagitis associated with CMV-induced gastritis. Emphasis is placed on the efficacy of immunohistochemical techniques over other methods in diagnosing CMV infection.
