Summary
Fine needle aspiration (FNA) can cause tissue necrosis, potentially leading to misdiagnosis. This study highlights how post-FNA infarction complicates accurate cancer diagnosis and treatment planning.
Area of Science:
- Pathology
- Oncology
- Diagnostic Imaging
Background:
- Fine needle aspiration (FNA) is a standard diagnostic tool for various masses.
- While generally safe, FNA can rarely cause complications like bleeding and infection.
- Tissue changes, specifically necrosis, following FNA have received limited attention.
Observation:
- Four cases demonstrated infarction after FNA biopsy.
- Diagnoses included papillary thyroid carcinoma, parotid gland pleomorphic adenoma, and breast fibroadenomas.
- Histologic examination of surgical specimens revealed extensive necrosis in these neoplasms.
Findings:
- Post-FNA infarction can lead to diagnostic challenges.
- Necrotic debris from FNA may result in false-negative diagnoses on repeat aspirations.
- Infarction can obscure the original nature of a neoplasm, complicating histological confirmation.
Implications:
- Awareness of post-FNA infarction is crucial for accurate pathological interpretation.
- Clinicians should consider infarction as a potential cause of diagnostic discrepancies after FNA.
- This phenomenon may necessitate careful review of FNA findings and consideration of alternative diagnostic pathways.
