Can you diagnose follicular carcinoma in fine needle aspiration biopsy?
Fine needle aspiration of a thyroid mass cannot diagnosis follicular thyroid cancer because it can only provide analysis of the cells themselves (which have the same appearance of normal follicular cells of the thyroid).
Can a benign follicular thyroid nodule turn cancerous?
Nodules that start as benign rarely turn cancerous. However, your endocrinologist will likely perform occasional biopsies to rule out the possibility. If your nodule is hot, or overproducing thyroid hormones, your endocrinologist will probably use radioactive iodine or surgery to eliminate the nodule.
What is a benign follicular thyroid nodule?
The word follicular means the cells look like a group of small circles under a microscope. If the follicular cells are contained within the nodule, the condition is called benign. If the cells have invaded the surrounding tissue, the diagnosis is cancer. Thyroid cysts are nodules filled with fluid.
How can you tell the difference between follicular adenoma and carcinoma?
A follicular carcinoma cannot be distinguished from a follicular adenoma based on cytologic features alone. It is distinguished from a follicular adenoma on the basis of capsular invasion, vascular invasion, extrathyroidal tumor extension, lymph node metastases, or systemic metastases.
What percentage of thyroid follicular neoplasms are benign?
The diagnosis “follicular neoplasm” is indeterminate, and the majority of cases (70% in the current study) are benign.
What is a follicular thyroid nodule?
Where are follicular cells found?
ovary and ovulation ) The follicles, which are hollow balls of cells, contain immature eggs and are present in the ovaries at birth; there are usually 150,000 to 500,000 follicles at that time.
Can a benign follicular nodule turn malignant?
Conclusion: Some benign thyroid nodules have malignant potential. Further molecular testing of these tumors can shed light on the pathogenesis of early malignant transformation.
What is suspicious for follicular neoplasm?
Definition. The general diagnostic category “follicular neoplasm” or “suspicious for a follicular neoplasm” refers to a cellular aspirate comprised of follicular cells, most of which are arranged in an altered architectural pattern characterized by significant cell crowding and/or microfollicle formation.
Should a follicular neoplasm be removed?
The issue is all of the follicular thyroid cancer must be effectively removed at the initial surgery. The problem is that both the patient and the surgeon may not know that the thyroid mass is a follicular thyroid cancer until after the surgery is completed.
What is the purpose of follicular cells?
The follicular cells of the thyroid gland synthesize and store thyroid hormones for release into the bloodstream.
What is the function of the follicle cells?
Abstract. The follicle plays a major role in the dual function of the ovary–oocyte maturation and release and steroidogenesis required for regulating its own growth and providing the proper environment in reproductive organs for the transport of gametes and nidation.
