Overview

Easy bruising is the bruising of skin with minor compression or pressure. When small capillaries of the superficial skin rupture from pressure or compression, petechiae occur, sometimes ecchymosis is also seen with insignificant trauma which is a bleed in the deeper layers in the skin[1]. A wide variety of causes lead to easy bruising, some of which are clotting and bleeding disorders, platelet dysfunction, age related skin changes, and some forms of cancer such as leukemia.[2]

Diagnosis

The algorithm below summarises approach to the different causes of easy bruising.[3][4]

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Detailed history:

❑ Is the bleeding over the limbs?
❑ Is there any bleeding in mucosal surfaces such as gums or oral mucosa?
❑ History of recent infections?
❑ Is there bleeding into the joints?
❑ Is there history of bruising after minor trauma in the past?
❑ Is there any associated rash?
❑ History of blood transfusions?
❑ History of bleeding after tooth extractions or surgeries
❑ Bleeding during menstrual cycle in women
❑ Drug history:
Any use of the following in the past?

Family history of bleeding?
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Characterize the symptoms
❑ Bruising with minor or no trauma
Petechiae
❑ Gingival bleeding
Menorrhagia
❑ Painful bleeding into joints
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Initial investigations
Complete blood count with platelet count
PT/aPTT
INR
Liver function tests
Thyroid function tests
Renal function tests
Peripheral smear
Bleeding time
Platelet function analyzer

Other investigations

Von Willebrand factor levels
Factor VIII level
Factor IX level
Fibrinogen level
ADAMTS13 level
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Disorders of secondary hemostasis
❑ Abnormal PT/aPTT
❑ Abnormal factor assays
❑ Abnormal fibrinogen level
 
Decreased platelet count
❑ mild: 100,000 - 150,000 per µL
❑ moderate: 50,000 to 99,000 per µL
❑ severe: <50,000 per µL (may require transfusion)
 
Disorders of platelet function
❑ Prolonged bleeding time
Thrombocytopenia
❑ Abnormal PFA-100
❑ Abnormal Von Willebrand factor assay
❑ Abnormal Ristocetin induced platelet agglutination
