Introduction: Approximately 10% of fine needle aspiration biopsy (FNAB) of thyroid nodules may be verified as “suspicious for follicular neoplasm”; this category involves follicular adenoma, follicular carcinoma, follicular variants of papillary carcinoma and subclass “suspicious for Hurthle cell neoplasm”. At present, there is no diagnostic tool to discriminate between follicular adenoma and cancer. Most patients are required surgery to exclude malignant process. The aim: To define factors correlating with risk of malignancy in patients with FNAB of thyroid focal lesions and nodules verified as Bethesda tier IV. Materials and Methods: In this study 110 consecutive patients were included. All patients were operated because of FNAB result “suspicious for follicular neoplasm” of thyroid gland at a single institution from January 2016 until March 2020. From this set, six specific categories were defined and the clinical records for patients were collected: sex, age, presence of oxyphilic cells, diameter of the tumour, presence of Hashimoto disease, aggregate amount of clinical and ultrasonographic features of malignancy according to ATA. Results: In 18 patients (16,3%) thyroid cancer occurred. Most frequent subtype turned out to be papillary cancer (66,6%). In group of benign lesion (92 patients) predominance of follicular adenoma was disclosed – (49%). Age, gender, tumour diameter, aggregate amount of clinical and ultrasonografic factors, presence of Hashimoto disease and fine needle aspiration biopsy result suspicious for Hurthle cell neoplasm did not correspond to increased risk of malignancy. Conclusions: In patients with FNAB results classified as Bethesda tier IV there are no reliable clinical features associated with low risk of malignancy and surgery should be consider in every case as most appropriate manner to exclude thyroid cancer

OBJECTIVE: The iodine status of the population of Poland has markedly improved over the past years. The aims of this paper were: (i) to examine the diagnostic value of fine-needle aspiration biopsy (FNAB) of the thyroid in goitre endemic regions (in conditions of improved iodine supply), and (ii) to find whether the changes in iodine supply have already influenced the clinical interpretation of cytological results. METHODS: Cytological diagnoses, based on 3782 aspirates, obtained from 3572 patients during the years 1985-1999, were verified by reference to the results of postoperative examinations. The relative occurrences of selected cytological results in 1992-1999 were also compared (patients not subjected to surgery were included). RESULTS: We have found that the frequency of neoplastic lesions significantly decreased throughout the examined period (P<0.02). The ratio of the papillary carcinoma frequency to the follicular carcinoma frequency increased from 1.7 during 1992-1993 up to 8.0 during 1998-1999 (P<0.05). The frequency of cytologically diagnosed chronic thyroiditis increased from 1.5% in 1992 to 5.7% in 1999 (P<0.001); the percentage of cytological diagnosis of "follicular neoplasm" decreased during the same time (P<0.001). The risk of malignancy significantly lowered in the cytological diagnoses of "follicular neoplasm" from 15% during 1985-1993 to 6% during 1996-1999 (P<0.05). CONCLUSIONS: The diagnostic value of FNAB during the period without proper iodine prophylaxis did not differ significantly from that during the last examined period. However, the changes in iodine supply have markedly and promptly affected the clinical significance of particular cytological results.

Purpose: To report ciliary body seeding 20 years after pars plana transvitreal fine needle aspiration biopsy (FNAB) of choroidal melanoma. Case Report: 67-year-old man with choroidal melanoma in left eye was previously managed with pars plana FNAB using a 25-gauge needle followed by plaque radiotherapy. Twenty years later, choroidal melanoma was regressed but there was a small flat focus of scleral pigment 3.0mm from the limbus at the FNAB site. Ultrasound biomicroscopy showed a contiguous ciliary body mass measuring 3.1mm in thickness. Tumor seeding in the anterior chamber angle was noted inferiorly. These findings suggested melanoma recurrence along the needle tract. Treatment was performed with Iodine-125 radioactive plaque covering entire anterior segment and ciliary body recurrence. The tumor regressed to 2.2mm over one year. Conclusion: Pars plana transvitreal FNAB of choroidal melanoma resulted in needle tract seeding in ciliary body and episcleral region 20 years later.
