The gastric location of EBVMCU is extremely rare. man with gastric EBV\positive mucocutaneous ulcer. We analyze through this observation the clinical, endoscopic, histological, and therapeutic characteristics of this entity. Epstein\Barr virus (EBV)\positive mucocutaneous ulcers (EBVMCU) were defined for the first time in 2010 2010 and share histological features with other B\cell proliferative neoplasms. 1 It has been reported in the setting of iatrogenic immunosuppression and immunosenescence, affecting the oropharyngeal mucosa, skin, and gastrointestinal tract (GIT). We present here an extremely rare case of a EBVMCU of the stomach. 2.?CASE PRESENTATION A 62\year\old man with a history of heavy smoking (94 pack\year smoking history) and brain attack was complaining of paroxystic epigastric pain, weight loss, and anorexia since 3?months. The patient has no medical history suggestive of autoimmune disease, HIV, or other infections. Complete skin examination was performed. There was no cutaneous or nodal Rtp3 involvement. He did not have hepatosplenomegaly or abdominal mass. His laboratory evaluation was negative for HIV, anti\HBsAg, and HCV antibodies. An upper gastrointestinal endoscopy was performed. A subcardial large ulcerous budding lesion in the greater stomach tuberosity was observed (Figure?1). Another similar lesion was found in the lesser curvature (Figure?2). Multiple ulcers were observed in the gastric body and the fundus (Figure?3). Histological examination showed an extensive ulceration with fibrin and leukocyte exudates (Figure?4). Atypical cells with basophilic cytoplasm resembling Hodgkin Reed\Sternberg cells associated with lymphocytes, histiocytes, plasma cells, and neutrophils were observed (Figure?5).?Immunohistochemistry was performed using monoclonal antibodies against CD20,?Compact disc30, Compact disc15 (Body?6), EBV, Compact disc3, Compact disc138, and C\Myc. Immunohistochemical evaluation of our individual depicted huge cells positive for Compact disc30, Compact disc15, EBV (Body?(Figure7),7), and Compact disc20 (Figure?8) whose appearance was heterogeneous.

Open up in another window Body 9 Compact CDKI-73 CDKI-73 disc3 marks reactive T lymphocytes Computed tomography (CT) of throat, chest, abdominal, and pelvis uncovered diffuse thickening from the gastric wall structure, fundic and antral especially. The differential medical diagnosis of EBVMCU contains diffuse huge B\cell lymphoma (DLBCL) connected with EBV. The individual underwent four cycles of CHOP (doxorubicin, cyclophosphamide, vincristine, and prednisone) without rituximab because of its preliminary unavailability. CT scan and higher gastrointestinal endoscopy with biopsy demonstrated stable disease. He’s going through R\CHOP chemotherapy. 3.?Dialogue We describe an instance of localized EBVMCU within a 62\season\aged guy with atypical and Hodgkin\want cells. EBVMCU have been recently described and are recognized by lymphoproliferative ulcerated skin or mucosal lesions with absence of hepatosplenomegaly and lymph nodes. This entity is usually associated with primary immunodeficiency, HIV contamination, or immunosenescence but also in patients with iatrogenic immunosuppression such as methotrexate or tumor necrosis factors (TNF) inhibitors. 2 Elderly patients without a history of immunosuppression like our patient can develop EBVMCU. 3 EBVMCU generally presents with a solitary lesion but can be CDKI-73 multifocal in 17% of cases in the literature. It usually occurs in the skin (29%), oral mucosa (52%), or gastrointestinal tract (19%\40% colon, 30% esophagus, 20% rectum, and 10% terminal ileum). 4 Since 2010, about 121 cases have been reported in the literature. 5 No cases of gastric EBVMCU were described in the literature. Our case in the first reported EBV\positive mucocutaneous ulcer localized in the stomach. Histological examination usually.
