Less common non-traumatic causes including: anticoagulation. [3] [4] [5] a ruptured aortic aneurysm. [5] a ruptured renal aneurysm. [6] acute pancreatitis. [citation needed] malignancy. [7] Retroperitoneal bleeds may also be iatrogenic, caused accidentally during medical procedures.
For example, a patient who injures the base of their thumb might cause a hematoma, which will slowly move all through their finger within a week. Gravity is the main determinant of this process. Hematomas on articulations can reduce mobility of a member and present roughly the same symptoms as a fracture .

While uncommon in solid tumors, chromosomal translocations are a common cause of these diseases. This commonly leads to a different approach in diagnosis and treatment of hematological malignancies. Hematological malignancies are malignant neoplasms ("cancer"), and they are generally treated by specialists in hematology and/or oncology.
