Background In patients with abnormal uterine bleeding, transvaginal ultrasound (TVS) is the first-line diagnostic approach to exclude endometrial pathology. If a thickened endometrium suggests endometrial pathology, sonohysterography, office hysteroscopy or dilatation and curettage are the second-line tests preferred, depending on availability and on the suspected pathology, to exclude malignan...

A 51-year-old man was referred for therapy of a submucosal tumor of the sigmoid colon. The lesion had been diagnosed during screening colonoscopy, and biopsies had shown gastrointestinal stromal tumor (GIST). We confirmed a 15-mm submucosal tumor located in the proximal sigmoid colon (●" Fig.1). Endoscopic full-thickness resection was performed with the Full Thickness Resection Device (FTRD; Ov...

Gastric hyperplastic polyps are generally considered benign lesions, although rare cases of adenocarcinoma have been reported. Two cases of intramucosal adenocarcinoma originating from gastric hyperplastic polyps that were successfully removed by endoscopic mucosal resection or endoscopic submucosal dissection are reported. On pathological examination, adenocarcinoma limited to the hyperplastic...

Inflammatory fibroid polyps or Vanek's tumors are rare benign pseudotumoral lesions with morphological characteristics similar to those of submucosal mesenchymal tumors. They have been described in the gastrointestinal tract, most frequently in the gastric antrum. We present a case of ileal Vanek's tumor associated with a raised carcinoembryonic antigen level and with radiological and endoscop...

This disease affects cats, but rarely dogs, and presents itself with erythematous extensive proliferations. Histopathological it can be determined by a submucosal infiltration with plasma cells. The aetiology is thought to be immunological due to the increased immunoglobulin level in the blood. The Plasmacytic Stomatitis diagnose can only be differentiated from other lesions by histopathology. ...

Gastric cancer remains still the most frequent type of cancer despite its declining incidence in Korea. As a result of the health promotion policy of the Korean government and increase in concern for individuals’ health, screening endoscopy for detecting early gastric cancer and general physical exams have become widespread. Thereby, the incidental detection of gastric submucosal tumors (SMTs) ...
