What are some disorders with bruising easily as a symptom?

Aplastic anemia and myelodysplastic syndromes are disorders that cause easy bruising, notes the National Institute of Diabetes and Digestive and Kidney Diseases. People with these disorders may also experience symptoms such as fatigue, weakness, shortness of breath, excessive bleeding and frequent infections.

Aplastic anemia is a condition in which the body slows down production or completely stops producing blood cells due to damaged bone marrow stem cells, states the National Institute of Diabetes and Digestive and Kidney Diseases. Blood cells that people with aplastic anemia produce are normal. Myelodysplastic syndromes is a condition in which bone marrow stem cells are defective and do not mature properly into red or white blood cells or platelets.
