Abstract:
Los leiomiomas gástricos son tumoraciones submucosas benignas, poco comunes, que se originan del músculo liso. Clínicamente son asintomáticos, con buen pronóstico y con pocas complicaciones a largo plazo. Reportamos el caso de un joven de 16 años que se presenta a la clínica con melena y dolor abdominal. En la endoscopia se reporta una tumoración prepilórica, ulcerada y cubierta de fibrina. El estudio histopatológico mostró una neoplasia mesenquimal con positividad inmunohistoquimica para desmina y actina, así como negatividad para C-kit, DOG-1 y S-100, compatible con leiomioma gástrico. Fue intervenido quirúrgicamente realizándose antrectomía laparoscópica con reconstrucción en Y de Roux de manera exitosa.
Abstract:
Gastric leiomyomas are rare, benign submucosal tumors originating from smooth muscle cells. They are usually asymptomatic, having good prognosis with limited long-term complications. A 16-year-old young man comes to our clinic and reports melena and abdominal pain. Upper endoscopy revealed a prepyloric, ulcerated, fibrin-covered tumor. Histopathological examination showed a positive immunohistochemical stain mesenchymal neoplasm for desmin and muscle actin, being negative for C-kit, DOG-1 and S100 proteins, consistent with gastric leiomyoma. Antrectomy with Roux-en-Y gastrojejunostomy was successfully performed.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
