Why is FNAC done in pleomorphic adenoma?
Why is FNAC done in pleomorphic adenoma?
In conclusion, FNAC is an ideal, fairly accurate preoperative procedure for the diagnosis of pleomorphic adenomas. Certain diagnostic problems occur in differentiating pleomorphic adenomas from adenoid cystic carcinoma, monomorphic adenoma and mucoepidermoid carcinoma.
What is the role of FNA for salivary gland tumors?
It alerts the surgeon to the possible presence of malignancy, helps in definition of a surgical plan regarding resection margins, assess the need for lymph node dissection and the degree of urgency of treatment.
How is pleomorphic adenoma diagnosed?
Diagnosis of Pleomorphic Adenomas
- Ultrasound scan.
- Computed tomography (CT)
- Nuclear magnetic resonance (NMR)
- Biopsy.
- Needle aspiration.
What is fine needle aspiration cytology FNAC?
Fine needle aspiration cytology (FNAC) entails using a narrow gauge (25-22G) needle to collect a sample of a lesion for microscopic examination. It allows a minimally invasive, rapid diagnosis of tissue but does not preserve its histological architecture.
Can pleomorphic adenoma be misdiagnosed?
The pleomorphic adenoma of nasopharynx is rare. It can be misdiagnosed as malignant epithelial tumor on histopathology. The differentiation from its malignant variant is also difficult.
Is a parotid gland biopsy painful?
With a needle biopsy, you may feel some stinging or burning if a local numbing medicine is injected. You may feel pressure or mild discomfort when the needle is inserted. This should only last for 1 or 2 minutes. The area may feel tender or be bruised for a few days after the biopsy.
Can a pleomorphic adenoma become malignant?
Pleomorphic adenomas harbor a small risk of malignant transformation. The malignant potential is proportional to the time the lesion is in situ (1.5% in the first five years, 9.5% after 15 years). Therefore, excision is warranted in almost all cases.
What can FNA diagnose?
During a fine needle aspiration (FNA), a small amount of breast tissue or fluid is removed from a suspicious area with a thin, hollow needle and checked for cancer cells. This type of biopsy is sometimes an option if other tests show you might have breast cancer (although a core needle biopsy is often preferred).
Which one is better FNAC or biopsy?
Core biopsy is better than FNAC at preoperative diagnosis of screen-detected breast cancer as it missed fewer cancers. However, combining FNAC resulted in a better preoperative diagnosis rate.
