A 60-year-old man presented with persistent dysphagia and weight loss of 2-months duration. An upper GI endoscopy revealed mycotic oesophagitis and chronic gastritis with two ulcers of the gastric body and antrum. Repeat endoscopy was performed after medical treatment failed, and histological examination on new biopsy samples led to a diagnosis of Kaposi sarcoma of the stomach. HIV infection was not known at this time; however, the patient was tested after the diagnosis of Kaposi sarcoma was made and found to be HIV positive. An adequate biopsy sampling was required for histological diagnosis and the use of immunohistochemical markers, especially human herpesvirus 8 (HHV8) antibodies, supplied valid diagnostic support. This case underlines the importance of an accurate evaluation of vascular proliferation in gastrointestinal biopsies even in patients without clinical evidence of HIV-related pathology.
