Lesions Primary lesion: Initial reaction to pathologically altered tissue that may be flat or elevated Secondary lesion: Result from the changes that take place in the primary lesion due to infection, scratching, trauma, or various stages of the disease.

Hemorrhage Contusion: Hemorrhage of any size, under the skin, in which the skin is not broken. AKA: A bruise. Petechia: Minute or small hemorrhagic spot on the skin Ecchymosis: Discoloration on the skin consisting of large, irregularly formed hemorrhagic areas. The color is blue- black, changing in time to greenish brown or yellow; commonly called a bruise Hematoma: Elevated, localized collection of blood trapped under the skin, usually the result of trauma.

More Treatment Cryosurgery: Use of subfreezing temperature to destroy abnormal tissue and cells. Debridement: removal of foreign material and dead or damaged tissue to promote healing.
