Open in a separate window Figure 2 Endoscopic findings. Multiple geographic ulcers with covered whitish exudates in the antrum are seen. Open in a separate window Figure 3 Microscopic findings. (A) A dense mononuclear cell infiltrate with prominent plasma cells in the lamina propria is observed (hematoxylinCeosin, 200). (B) Numerous spirochetes are seen within the lamina propria (WarthinCStarry silver stain, 400). 2.2. Case 2 A 33-year-old man presented at the outpatient clinic with a 1-month history of epigastric pain. Physical examination revealed mild abdominal tenderness in the epigastrium. Laboratory evaluation revealed normal hemoglobin, hematocrit, white blood cell count, and hepatic and renal function. The serum treponema pallidum hemagglutination test was positive, with Exemestane a titer of 1 1:1280, and the FTA-ABS test was reactive. Serum HIV antibodies were negative. EGD showed multiple variable-sized whitish discolored flat elevated lesion with focal erosion and ulceration on the body (Fig. ?(Fig.4A)4A) and large geographic ulcers with regular edges and even whitish exudates on the lesser curvature side of the lower body (Fig. ?(Fig.4B).4B). WarthinCStarry silver staining of endoscopic biopsy specimens confirmed gastric syphilis. He was treated with an intramuscular injection of 2.4 million units of benzathine penicillin once a week for 3?weeks. The patient’s clinical symptoms and gastric lesions were completely resolved. Informed consent was obtained from the patient for the purpose of publication. Open in a separate window Figure 4 Endoscopic findings. (A) Multiple variable-sized whitish discolored flat elevated lesions with focal erosion and ulceration on the body. (B) Large geographic ulcers with regular edges and even whitish exudates on the lesser curvature side of the lower body. 3.?Discussion Syphilis is a chronic systemic infection caused by in gastric lesions via WarthinCStarry silver staining, immunofluorescence, or polymerase chain reaction.[17C19] In our study, was detected in biopsied specimens via WarthinCStarry silver staining and FTA-ABS complement staining in Exemestane 8 cases and 1 case, respectively, and was negative in only one of the WarthinCStarry silver staining cases. An intramuscular injection of benzathine penicillin G is recommended as an appropriate antibiotic for the treatment of gastric syphilis. In principle, the duration of treatment should be determined according to the stage of syphilis.[1C5] In our study, the majority of patients with gastric syphilis were treated with an intramuscular injection of 2.4 million units of benzathine penicillin once a week for 3?weeks. Rabbit polyclonal to HRSP12 Appropriate antibiotic treatment of gastric syphilis improves clinical symptoms and gastric lesions.[1C5] In a previous report, clinical symptoms usually disappeared in approximately 3 to 4 4?days, and gastric lesions began to improve as early as 10?days after the initiation of treatment.[2] In our study, clinical symptoms improved after 3 to 25?days, and endoscopic findings usually improved after 1 to 3?months of treatment. In summary, first, gastric syphilis, despite its rarity and nonspecific symptoms and endoscopic findings, should be considered in a rare extracutaneous Exemestane presentation of syphilis. Second, a high index of clinical suspicion and an accurate diagnosis based on a combination of clinical, radiological, endoscopic, serologic, and histopathologic findings provide an opportunity to identify and treat patients with gastric syphilis.
