Platelet-derived growth factor receptor-beta in Gorham's disease

Area of Science:

• Rare bone diseases
• Vascular anomalies
• Congenital abnormalities

Background:

• A 17-year-old male with a history of congenital rib anomalies presented with chest pain and an enlarging chest wall mass.
• The patient also experienced vertebral erosion and pleural effusion, indicating disease progression.

Observation:

• Diagnostic workup included physical examination, imaging (X-ray, MRI, CT), biopsy, immunohistochemistry, flow cytometry, and serological assays.
• The findings were consistent with Gorham's lymphangiomatosis, characterized by platelet-derived growth factor receptor-beta expression and elevated platelet-derived growth factor-BB.

Findings:

• Management involved a combination of surgical interventions (spine stabilization, thoracotomy, pleurectomy, talc pleurodesis) and pharmacotherapy (thalidomide, celecoxib, interferon-alpha2b, bisphosphonates, imatinib mesylate).

Implications:

• This case highlights the diagnostic challenges and complex management strategies for Gorham's lymphangiomatosis.
• Multidisciplinary care is crucial for addressing the skeletal, vascular, and oncological aspects of this rare condition.
