An extensive bluish discoloration of the skin of the breast is visible. Hematoma is surgically drained, after bleeding is stopped, under local anesthesia.
Case Discussion
The diagnosis of traumatic breast hematoma is easy due to history of a direct trauma and the ecchymotic suffusion of the skin. She has no history of coagulation disorders neither takes medications. The diagnostic blood tests (CBC, PT/INR, PTT) are normal.
It is important to keep in mind that:
hematoma may be related to coagulopathy or the use of some drugs (aspirin, NSAIDs, anticoagulants)
a hematoma without a history of trauma may be related to a tumor causing the hemorrhage
infection is a possible complication of hematoma
Treatment: hematomas should be surgically drained after bleeding is stopped if it is of large size or causing pain.
