Severe gastrointestinal-tract injury due to ingestion of caustic substances is not an infrequent problem in the emergency department. We report case a 57-year-old male who developed massive hemorrhagic, gastric necrosis non-diluted solution containing hydrochloric acid, which propitiated urgent surgical procedure. The esophago-gastrectomy specimen showed extensive hemorrhagic with important damage wall histopathological evaluation. medical that still frequent departments, either by mistake...

1. Measurements of tracheid length from a series tangential sections confirmed the usual pattern change in mean through growth ring and similar false ring. 2. Cell-series traced these showed that most pseudo-transverse divisions cambium occur at boundary. Similar mother cells early wood appear to be major factor reducing wide rings. There is appreciable intrusive late tracheids.
