Gastric Schwannoma: A Rare Cause of Gastric Bleeding.

Gastric schwannomas and gastrointestinal stromal tumors (GISTs) are two types of mesenchymal tumors, which represent a group of rare tumors of the gastrointestinal tract. The differential diagnosis between these two tumors is difficult given their very similar appearance and clinical features. The authors present a case of a 63-year-old man with melena and epigastric pain.

Hemoperitoneum secondary to mesenteric laceration after abdominal trauma - Case report.

Mesenteric laceration is an uncommon cause of hemoperitoneum, with nonspecific signs and symptoms and frequently is camouflaged by the signs of other traumatic lesions. There is a high risk to go unnoticed increasing morbidity and mortality. We report a case of a 43-year-old man, who was involved in a motorcycle accident, with thoraco-abdomino-pelvic trauma, but without evidence of intra-abdominal lesions on exams, with exception of hemoperitoneum.

Accuracy of Corneal Thickness by Swept-Source Optical Coherence Tomography and Scheimpflug Camera in Virgin and Treated Fuchs Endothelial Dystrophy.

Purpose: To assess intraobserver repeatability, intersession reproducibility, and agreement of swept-source Fourier-domain optical coherence tomography (SS-OCT) and the Scheimpflug camera in measuring corneal thickness in virgin and grafted eyes with Fuchs endothelial corneal dystrophy (FECD).

Methods: Thirty-six control eyes, 35 FECD eyes, 30 FECD with corneal edema eyes, 25 Descemet stripping automated endothelial keratoplasty (DSAEK) eyes, and 29 Descemet membrane endothelial keratoplasty (DMEK) eyes were included. The apical center, pupillary center, and thinnest corneal thickness were determined in 3 consecutive images and repeated 2 weeks later.

Trichobezoar - A Rare Cause of Abdominal Mass and Gastric Outlet Obstruction.

The authors present the clinical case of a 14-year old girl with weight loss, anorexia, epigastric abdominal pain and postprandial vomiting with 5 months duration. There was a background of trichophagia for 2 years without evidence of alopecia or psychiatric history. The physical examination revealed an epigastric mass motionless, stony, with poorly defined limits, painful on palpation and about 7 cm diameter.

Diffuse vascular hamartoma with malignant behavior.

Pulmonary hamartomas are benign lesions, usually asymptomatic and incidentally discovered on a routine chest radiograph; occasionally, however, this benign lesion may cause life threatening symptoms due to it's location and diffuse vascular involvement. We report the case of a 27 year-old male, non-smoker, who presented with dyspnea, cough, hemoptysis and weight loss. He was found to have a mass in the right hilar region which also involved the right main bronchus, pulmonary artery and esophagus.
