BPOP – Bizarre Parosteal Osteochondromatous Proliferation

Bizarre Parosteal Osteochondromatous Proliferation (BPOP) is a rare, benign bone lesion that usually affects the long bones of the arms and legs. BPOP is characterized by the growth of abnormal, cartilage-covered bony projections that arise from the surface of bones. These projections can be singular or multiple and can vary in size, shape, and location.

Signs and Symptoms of BPOP:

  • Pain: BPOP can cause pain, especially when the affected bone is being used, such as with repetitive motions or weight-bearing activities.
  • Swelling: The growth of the bony projections can lead to swelling in the affected area.
  • Stiffness: BPOP can cause stiffness in the affected joint, making it difficult to move.
  • Tenderness: The area around the growth may be tender to the touch.
  • Limitation of movement: In severe cases, BPOP can limit the range of motion in the affected joint.


Diagnosis of BPOP:

BPOP is typically diagnosed through a combination of imaging tests and physical examination. This can include:

  • X-rays: X-rays can show the location, size, and shape of the bony projections and can help distinguish BPOP from other bone lesions.
  • Magnetic resonance imaging (MRI): MRI can provide more detailed images of the affected area and can help to determine the extent of the lesion.
  • Biopsy: In some cases, a biopsy may be performed to confirm the diagnosis and rule out other possible causes of the symptoms.


Treatment of BPOP:

The treatment for BPOP depends on the size and location of the lesion and the symptoms it is causing. Options can include:

  • Observation: If the lesion is small and not causing any symptoms, it may be monitored with regular imaging tests.
  • Surgical excision: In cases where the lesion is causing pain or limiting joint mobility, surgical removal may be necessary.
  • Physical therapy: Physical therapy may be recommended to help improve joint mobility and relieve pain after treatment.

In conclusion, BPOP is a rare and benign bone lesion that can cause pain, swelling, stiffness, and limitation of movement. If you experience any of these symptoms, it is important to seek medical attention for an accurate diagnosis and appropriate treatment. Early diagnosis and treatment can help to prevent further complications and improve outcomes.
