Mediastinal tuberculous lymphadenitis rarely mimics esophageal submucosal tumor, particularly in the case of multidrug-resistant tuberculosis (MDR-TB). Herein, we report the case of a 61-year-old woman who visited a local hospital complaining of odynophagia. An initial esophagogastroduodenoscopy revealed an esophageal submucosal tumor, and subsequent chest computed tomography showed subcarinal ...

The options for management of submucosal nodules in the small bowel are limited. A 67-year-old woman presented for evaluation after positive findings from fecal immunochemical testing. Colonoscopy showed a 2-cm submucosal nodule in the terminal ileum. Superficial biopsies from the lesion were unrevealing. Over-thescope clip (OTSC)-assisted resection was planned. An OTSC (size 12/6, type gc) was...

RATIONALE A cecal submucosal fecalith is extremely rare and is likely to be misdiagnosed as appendicitis with an incarcerated fecalith. PATIENT CONCERNS This review presents the case of a female patient complaining of recurrent abdominal pain in the right lower quadrant, similar to the clinical symptoms of appendicitis. Physical examination revealed an abdominal tenderness in the right lower ...

Routine screening esophagogastroduodenoscopy in an asymptomatic woman over 40 years of age revealed a small submucosal tumor with a yellowish appearance in the antrum (Picture 1, 2). On endoscopic ultrasonography, a lowechoic mass with a clear border involving the deeper side of the mucosa to the submucosa was visualized. In the differential diagnosis, the possibility of a neuroendocrine tumor ...

Inflammatory fibroid polyp (IFP) is a rare benign lesion of the gastrointestinal tract. We report a case of computed tomography (CT) imaging finding of a gastric IFP with massive fibrosis. CT scans showed thickening of submucosal layer with overlying mucosal hyperenhancement in the gastric antrum. The submucosal layer showed increased enhancement on delayed phase imaging. An antrectomy with gas...

Phlegmonous gastritis is a rare and rapidly progressive bacterial infection of the stomach wall, with a high mortality rate. Antibiotics with or without surgical treatment are required for treatment. We present a case in which phlegmonous gastritis occurred during the diagnostic evaluation of early gastric cancer. The patient showed improvement after antibiotic treatment, but attempted endoscop...

In our previous study, the healing effect of proton pump inhibitor plus rebamipide for endoscopic submucosal dissection-related artificial ulcer smaller than 40 mm showed statistical significance. However, such effect of the combination was not yet clear for ulcers with dissected diameter more than 40 mm. The aim of this present study was to resolve this problem under sufficient statistical pow...

BACKGROUND Rheumatoid nodules are a common manifestation of rheumatoid arthritis but buccal rheumatoid nodules are extremely rare. The purpose of this study was to report a rare case of a rheumatoid buccal nodule and a review of the literature. METHODS AND RESULTS This case is about a 79-year-old woman with rheumatoid arthritis who was taking methotrexate and hydroxychloroquine, presenting wi...

A 37-year-old woman was found to have a submucosal mass in the gastric antrum. She presented with recurrent episodes of right upper quadrant pain. Evaluation included a normal abdominal ultrasonography and esophagogastroduodenoscopy, which revealed a benign appearing 1 cm sessile polypoid mass in the gastric antrum (Image 1). The gastric mucosa over the mass was normal both visually and histopa...

Castleman disease is a relatively rare disorder of lymphoid tissue that involves the gastrointestinal tract in a variety of clinical and pathologic manifestations. A submucosal location has never been described in the medical literature. We report a case of esophageal Castleman disease involving the submucosal layer in a 62-year-old man, which was confirmed on pathology. Esophagography and CT d...
