Skin - Hemorrhage
comment:
Hemorrhage in the skin is characterized by clusters of extravascular erythrocytes ( Figure 1
recommendation:
In cases where hemorrhage is associated with a proliferative vascular lesion, it should not be recorded. If the hemorrhage is associated with another lesion, such as inflammation or ulceration, it need not be recorded unless the severity of the hemorrhage is excessive or is not commensurate with the severity of the associated lesions. However, it should be described in the pathology narrative. Whenever it is recorded, hemorrhage should be assigned a severity grade.references:
