Gastric leiomyoma is an uncommonly found benign submucosal neoplasm which may cause hemorrhage in rare cases. A 67-years-old patient was admitted to our attention due to two episodes of hematemesis and melena occurred in the previous two days. Esophagogastroduodenoscopy showed a giant semi-pedunculated gastric polyp (diameter of 4 centimeters) located at the distal body. A large ulcer with a cl...

Intussusception in adults is a rare phenomenon involving the colon in approximately 20% of cases. A 65-year-old man was hospitalized with anorexia, anemia, dehydration, and melena. Digital rectal examination revealed a palpable mass approximately 5 cm from the anal verge. The mass moved between the rectosigmoid colon and the rectum below the peritoneal reflection during radiographic examination...

Benign oropharyngeal tumors are far less common compared to malignant tumors. Oropharyngeal papilloma is present in adults. Squamous papillomas are exophytic masses of oral cavity. When they occur on the palate they are most often asymptomatic and benign. Pedunculated squamous papillomas usually arise from the soft palate, tonsil, or the epiglottis. These lesions can sometimes prove to be fatal...

CLINICAL TYPES. (1)' Ulcerative type-characterised clinically by the presence of one or more miliary ulcers, which may or may not coalesce. They are usually found on the palpebral conjunctiva, rarely on the bulbar conjunctiva. (2) Nodular type-characterised by small greyish subcorjunctival nodules, which are very difficult to differentiate from trachomatous granules. (3) Hypertrophic papillary ...

We report a rare case of metastasis of hepatocellular carcinoma (HCC) to the small bowel that presented as a pedunculated epithelial polyp. A 60-year-old man with liver cirrhosis type B was treated for HCC (stage IVb) at our hospital. He had been admitted for melena and anemia. Capsule endoscopy was performed in this patient with obscure gastrointestinal bleeding. It showed a polypoid lesion wi...

BACKGROUND Myxoma is a very rare benign cardiac tumor in dogs. This is the first description of a cardiac myxoma originating from the left ventricular outflow tract, presumably causing sudden death. CASE PRESENTATION A previously healthy 12-year-old male West Highland white terrier was found dead during its 1-week stay in a kennel. The dog was known to have a cardiac murmur. On necropsy, a pe...

lon polypectomy. A colonoscopic examination had been carried out in another hospital several days earlier due to hematochezia and a polyp had been found in the sigmoid colon. The 1.5-cm, pedunculated polyp (●" Fig. 1) had a slight bulge in the stalk, and there was a mucosal bridge at the attachment to the intestinal wall, mimicking a submucosal tumor. The polyp was resected at the midportion of...

Pancreatic neuroendocrine tumors (PanNETs) are usually located entirely within the pancreatic parenchyma. However, unusual exophytic or pedunculated PanNETs sometimes discovered in imaging studies, requiring differential diagnosis with various peripancreatic and non-tumors. Herein, an PanNET whose origin was identified only after surgical exploration is presented along potential radiologic diag...
