Thyroid Surgery Report and Nodule Issues
Hello, Doctor.
I have multiple nodules (0.4 cm to 0.8 cm in size) on both sides of my thyroid, and the doctor mentioned that one of them has an irregular shape.
I was given the option of surgery or close monitoring, but after two fine needle aspirations yielded insufficient cells, I chose to proceed with surgery.
Q1.
Here is the pathological report from my thyroid surgery: Microscopic examination shows thyroid tissue with hyperplasia of follicle cells.
The sections of the left and right thyroid reveal hyperplastic follicles of variable sizes.
Could you please explain this to me? Thank you!
Q2.
I read in educational articles about thyroid nodules that if it is a follicular thyroid tumor, a total lobectomy of the affected side is necessary to determine whether it is benign.
Since I had a total lobectomy on one side and a subtotal lobectomy on the other, does this mean I can rule out this possibility? Or is a follicular thyroid tumor different from regular nodules?
Q3.
If it were a follicular thyroid tumor, would it be indicated in the pathology report?
Q4.
Are thyroid nodules and thyroid adenomas the same thing?
I apologize for asking so many questions, but I am worried and cannot find answers, so I wanted to consult you.
Thank you very much for taking the time to respond to my questions!

Hello, netizen: 1.
The pathology report should indicate a benign hyperplastic nodule; 2.
Benign nodules are certainly different from follicular thyroid tumors; one is benign (surgical excision is sufficient), while the other is malignant (surgical excision may require adjuvant therapy depending on clinical circumstances); 3.
If the pathologist observes vascular and capsular invasion in the biopsy, it should be explicitly noted; 4.
If a palpable mass is less than 3 cm, it is clinically referred to as a nodule; if it is greater than 3 cm, it is referred to as a mass.
Therefore, clinically, the terms nodule and mass are used to distinguish the size of the lesion, while benign and malignant status requires pathological confirmation (for example, distinguishing between follicular hyperplasia and follicular thyroid carcinoma necessitates complete excision followed by assessment for vascular and capsular invasion to confirm benign or malignant status); P.S.: Some of your questions are already foundational and pathological in nature; for more detailed information, you should consult a pathologist.

Understanding thyroid surgery reports and the implications of thyroid nodules can be quite complex, especially when dealing with conditions such as follicular thyroid neoplasms. Let’s address your questions one by one.
Q1: Interpretation of the Pathology Report
The pathology report indicates that the microscopic examination shows thyroid tissue with hyperplasia of follicle cells. This means that the thyroid tissue is enlarged due to an increase in the number of follicle cells, which are the cells that produce thyroid hormones. Hyperplastic changes can occur in response to various stimuli, including hormonal changes or benign conditions. The presence of hyperplastic follicles of variable sizes suggests that there is a non-uniform growth pattern, which is often seen in benign conditions. However, it is essential to correlate these findings with clinical and imaging studies to determine the next steps.
Q2: Follicular Thyroid Neoplasm and Surgical Implications
Regarding the concern about follicular thyroid neoplasms, it is true that definitive diagnosis often requires complete surgical removal of the affected lobe. This is because follicular thyroid neoplasms can be either benign (adenomas) or malignant (carcinomas), and distinguishing between the two can be challenging based solely on fine needle aspiration (FNA) biopsies. Since you underwent a total lobectomy on one side and a partial lobectomy on the other, the pathology results from these excised tissues will provide crucial information. If the pathology report indicates a benign process, the risk of malignancy is significantly reduced. However, if there are any atypical features noted in the report, further evaluation may be warranted.
Q3: Reporting of Follicular Thyroid Neoplasm
If the pathology report identifies a follicular thyroid neoplasm, it should be explicitly stated in the report. The report may describe the characteristics of the neoplasm, including whether it appears benign or malignant based on the histological features. If the report does not mention a follicular neoplasm, it is likely that the findings were consistent with hyperplasia or another benign condition. Always consult with your healthcare provider for a detailed explanation of the pathology report.
Q4: Thyroid Nodules vs. Thyroid Adenomas
Thyroid nodules and thyroid adenomas are related but not identical. A thyroid nodule is a general term that refers to any abnormal growth within the thyroid gland, which can be solid or cystic. Thyroid adenomas are a specific type of thyroid nodule that is benign and composed of thyroid follicular cells. Not all thyroid nodules are adenomas; some may be cysts, colloid nodules, or even malignant tumors. Therefore, while all adenomas are nodules, not all nodules are adenomas.
In summary, your concerns about the pathology report and the nature of your thyroid nodules are valid and important. The findings of hyperplasia suggest a benign process, but the definitive diagnosis will depend on the complete pathology report and the surgical outcomes. It is crucial to maintain open communication with your healthcare provider to discuss the implications of these findings and any necessary follow-up care. Regular monitoring and follow-up imaging may be recommended based on your individual risk factors and the results of your surgery.
