Summary
Castleman disease, a rare lymphoproliferative disorder, can present as a middle mediastinal mass. Awareness of this condition is crucial due to potential bleeding risks during biopsy.
Area of Science:
- Thoracic oncology
- Diagnostic imaging
- Pathology
Background:
- Mediastinal masses require accurate diagnosis for effective treatment.
- Castleman disease is a rare lymphoproliferative disorder with unclear origins.
- Enhancing mediastinal lesions pose diagnostic challenges.
Observation:
- A 25-year-old male presented with an enhancing middle mediastinal mass.
- Repeated biopsies were nondiagnostic and complicated by significant hemorrhage.
- Imaging modalities included Magnetic Resonance (MR) and Computed Tomography (CT).
Findings:
- Final diagnosis after thoracotomy and debulking was Castleman disease.
- Castleman disease presents in hyaline vascular (80-90%) and plasma cell (10-20%) subtypes.
- Surgical excision is the typical curative treatment.
Implications:
- Castleman disease should be considered in the differential diagnosis of enhancing mediastinal masses.
- Clinicians must be aware of the risk of severe bleeding complications associated with biopsies of such lesions.
- Timely and accurate diagnosis is essential for appropriate management and improved patient outcomes.
