Gastric syphilis: a systematic review of published cases of the last 50 years

Abstract

The authors conducted a systematic review of the English literature for cases of Gastric Syphilis (GS) in the last 50 years. The 34 studies which met selection criteria included 52 patients with GS. Of the reviewed patients, only 13% had a history of syphilis diagnosis and 46% had prior or concurrent clinical manifestations of the disease. Epigastric pain/fullness was the most common presenting symptom (92%) and epigastric tenderness being the most common sign. Gastric bleeding of variable intensity was documented in 35% of the cases. In the radiologic examinations, fibrotic narrowing and rigidity of the gastric wall was the most common finding (43%), followed by hypertrophic and irregular folds, while in endoscopy the most common lesion types were multiple ulcerations (48%), nodular mucosa, and erosions. The antrum was the most commonly affected area (56%). The majority of the patients received penicillin (83%) with a rapid resolution of their symptoms. Seventeen percent of the patients were treated surgically either due to a complication or due to strong suspicion of infiltrating tumor or lymphoma. The nonspecific clinical, radiologic, and pathologic characteristics of GS can establish it as a great imitator of other gastric diseases. GS should be considered in the differential diagnosis in patients at risk for sexually transmitted diseases who present with abdominal complaints and unusual endoscopic lesions and no other diagnosis is made, irrespective of the presence of H. pylori. The absence of primary or secondary luetic lesions should not deter one from considering GS.
