Diagnosis of Breast Implant Associated Large Cell Lymphoma

  • Periprosthetic fluid collections:
    • Occurring more than 1 year after implantation:
      • Should be evaluated to rule out breast implant-associated anaplastic large cell lymphoma (BIA-ALCL)
  • Diagnosis of BIA-ALCL:
    • Is made by aspiration of the periprosthetic fluid:
      • Usually performed by fine needle aspiration:
        • Under ultrasound guidance
      • A sample of 50 ml or greater is sufficient to establish a diagnosis by CD30 immunohistochemistry:
        • CD30 is a cell surface protein expressed by roughly 5% of normal circulating T-cells:
          • However, BIA-ALCL demonstrates confluent staining of CD30
  • Open biopsy:
    • Is more invasive, and the capsule may be negative even in the presence of disease
  • Therefore, effusion FNA is preferred for diagnosis
  • Plastic surgery evaluation:
    • Is not appropriate or necessary
  • Mammogram evaluation is non-specific for a disease process and is not indicated with an obvious fluid collection
