Summary
Fine-needle aspiration biopsy is an accurate, minimally invasive tool for diagnosing soft tissue masses. This method effectively identifies benign, malignant, metastatic, and recurrent tumors with high sensitivity and specificity.
Area of Science:
- Pathology
- Oncology
- Surgical Pathology
Background:
- Fine-needle aspiration (FNA) biopsy for soft tissue masses is uncommon and debated.
- Traditional methods include excision or incisional biopsy for tissue procurement.
Purpose of the Study:
- To evaluate the diagnostic utility of FNA biopsy for soft tissue masses.
- To assess the accuracy and safety of FNA in diagnosing neoplastic and non-neoplastic soft tissue lesions.
Main Methods:
- Reviewed 82 FNA procedures from 77 patients over 11 months.
- Diagnoses were confirmed via tissue examination, flow cytometry, clinical outcome, or repeat FNA.
- Patients were followed for at least one year for clinical evaluation and disease status.
Main Results:
- 51% of masses were malignant, 39% benign; 100% sensitivity and 97% specificity for malignancy.
- Malignant aspirates included sarcomas, carcinomas, lymphomas, and melanomas.
- Accurate subtyping was achieved in 83% of malignant and 72% of benign aspirates.
Conclusions:
- FNA biopsy is an accurate, minimally invasive method for initial diagnosis of soft tissue masses.
- It aids in confirming metastatic tumors and documenting recurrent neoplasms.
- Subtyping is feasible with additional cell block or flow cytometry data.
