The differential diagnosis of a follicular lesion/neoplasm in thyroid FNA specimens includes hyperplastic/adenomatoid nodule, follicular adenoma and carcinoma, and follicular variant of papillary thyroid carcinoma. In our laboratory we separate follicular lesions of thyroid into hyperplastic/adenomatoid nodule (HN), follicular neoplasm (FON) and follicular derived neoplasm with focal nuclear features suspicious for papillary thyroid carcinoma (FDN).This study reports our experience with 339 cases diagnosed as FON and 120 as FDN.All cases were evaluated for histologic diagnosis, age, sex and size of the nodule. Histopathologic follow-up was available in all cases. The malignancy rate was 22% (74/359) and 72% (86/120) for cases diagnosed as FON and FDN, respectively. In the FON category almost half of the malignant cases were papillary carcinoma. The risk of malignancy was higher in patients younger than 40 yr (53% vs. 30%) than in patients 40 year or more years old and greater in males (41% vs. 33%) than females. No statistically significant relationship was noted between the sizes of the nodules and benign vs. malignant diagnosis.According to this study it is important to divide follicular patterned lesions of thyroid into FON and FDN in the cytology specimens due to significantly different risk of malignancy (22% vs. 72%). In addition, clinical features, including gender and age can be part of the decision analysis in selecting patients for surgery.

Ultrasound examination (US) is an essential tool in the evaluation of thyroid nodules. The size determined by US is used to distinguish between clinical vs. nonclinical thyroid nodules i.e. greater than or equal to or less than 1 cm. In this study, we evaluated the concordance between the sizes of thyroid nodules measured by US and by gross examination after thyroidectomy. This study included 664 nodules that underwent fine-needle aspiration (FNA) and subsequent excision in 621 patients; 580 had single and 41 patients had multiple (39 with 2, and 2 with 3 nodules) nodules. Both US and gross pathology measurements were taken in three dimensions. The nodule sizes as measured by US were stratified into five groups: A: or=5.1 cm. FNA diagnoses were categorized into: Benign (n = 59), Neoplastic / Indeterminate (n = 342), Suspicious (n = 123), Malignant (n = 106), and nondiagnostic (n = 34). Upon excision 278 (42%) nodules were classified as malignant and 386 (58%) as benign. In group A the concordance between US and excisional size was 78.5%, group B 56%, group C 34.5%, group D 40% and group E 52.5%. Only 14 (14/664 2%) nodules measured

Villoglandular papillary adenocarcinoma (VPA) of cervix is rare but a well recognized variant of cervical adenocarcinoma with favorable prognosis occurring in younger age group. A 28-year-old white woman, gravida 3, para 2 was admitted for abnormal vaginal bleeding, when she was pregnant at 8th weeks of gestation. Physical examination revealed about 2.5 cm polipoid lesion of the cervix protruding into vagina. Histopathological findings were consistent with cervical VPA. After termination of pregnancy, radical hysterectomy type III was performed. The patient underwent second, third and fourth laparotomies because of recurrent pelvic masses. At the end of five years follow-up period, she died because of the complication of recurrent tumor. VPA is not an innocent tumor, and can be complicated by recurrence and metastasis. More radical surgical and medical attempts should be planned. uterine cervix; adenocarcinoma; villoglandular type
