Hematomas, also known as bruises, are traumatic accumulations of blood in the skin and possibly the underlying fat tissue. They occur due to the rupture of blood vessels, with blood leaking into the surrounding tissue.

Characteristics

• Varying severity
• May be fluctuating (changing consistency)
• Can extend from the skin into the subcutaneous fat tissue

Clinical Appearance

• Painful soft tissue swelling
• Skin discoloration

Color Progression

Hematomas go through characteristic color stages, which can indicate their age:

• Bluish-red (fresh hematoma)
• Blue
• Greenish-yellow
• Yellow (older hematoma)

This color progression results from the breakdown of hemoglobin and reflects the healing process.

Etiology

The most common causes of hematomas are:

• Blunt trauma (e.g., bumps, blows, bruises)
• Surgery
• Blood clotting disorders
• Use of anticoagulant medications

Diagnosis

Diagnosis is typically clinical, through:

• Visual inspection
• Palpation of the affected area

In some cases, imaging methods like ultrasound or MRI may be used for a more detailed assessment of the extent.

Treatment

The treatment of hematomas focuses on relieving pain and speeding up the resorption of the leaked blood:

• Acute phase (first 24-48 hours):
  • Cooling the affected area
  • Elevation to reduce swelling
  • Compression to minimize further bleeding
• Later phase:
  • Heat applications to promote blood circulation and resorption
  • Heparin ointments: Promote resorption and relieve pain
  • Gentle massage to support lymphatic drainage
• Medications:
  • Pain-relieving medications as needed
  • In severe hematomas, oral enzyme preparations may aid resorption

Complications

In rare cases, complications may occur:

• Infection of the hematoma
• Compartment syndrome with large, deep hematomas
• Chronic hematomas with calcification (myositis ossificans)

Prevention

Preventive measures include:

• Wearing protective equipment during high-risk activities
• Caution when taking blood-thinning medications
• Proper management of blood clotting disorders
