Salivary Gland - Hemorrhage
comment:Hemorrhage can occur secondary to trauma, inflammation of vessels, or vascular damage secondary to chemical toxicity. Hemorrhage is frequently seen in areas of necrosis. Hemorrhage should be differentiated from angiectasis. With angiectasis, a careful search will confirm that the blood is actually contained within spaces lined with endothelial cells.
recommendation:Hemorrhage should be diagnosed and graded based on the extent and number of areas involved. If hemorrhage is a part of another lesion (e.g., necrosis, inflammation, or neoplasia), it should not be diagnosed separately unless warranted by severity but should be described in the narrative.
