Annual increase in the frequency of papillary thyroid carcinoma as diagnosed by fine-needle aspiration at a cytology unit in Sicily.

Objective: An increased frequency of papillary thyroid carcinoma (PTC) has been reported in the literature, including studies based on fine-needle aspiration cytology (FNAC).

Design: To substantiate our own ascertainment of such an increase, we retrieved all the diagnoses of ultrasound-guided FNAC which was performed on 11,389 patients referred for cytological evaluation of a single or dominant thyroid nodule from 1988 to 2010. FNAC yielded 11,258 adequate specimens.

Increased annual frequency of Hashimoto's thyroiditis between years 1988 and 2007 at a cytological unit of Sicily.

Like other auto-immune diseases, Hashimoto's thyroiditis (HT) results from the interaction of genetic with environmental factors. Only few studies have evaluated the year-to-year change in frequency of HT over a wide period of time. The endocrine division of our Hospital has reported a great increase in the annual frequency of HT between 1975 and 2005, and a progressive decrease in both age at presentation and female to male (F/M) ratio starting in the mid-1990s.

Thyroid metastasis of clear cell renal carcinoma: Report of a case.

Renal cell carcinoma can recur many years after diagnosis and nephrectomy metastasizing even in uncommon sites, including thyroid gland. Thyroid metastases are extremely rare, the most frequent site of origin are renal tumors. Metastases in thyroid gland appear as painless nodules or masses, "cold" at scintiscan.

The role of ultrasound-guided aspiration biopsy of peripheral pulmonary nodules: our experience.

Background: Peripheral lung lesions are difficult to diagnose with conventional methods: ultrasound-guided aspiration biopsy is an interesting prospect having been reported to have good sensitivity and specificity.

Patients And Methods: From January 1991 to August 2001 we investigated, in 268 patients, the role of ultrasound-guided transthoracic fine needle aspiration for cytological diagnosis of peripheral lung lesions. Nodule sizes ranged from 1 to 10 cm.

Diagnosis and survey of abnormal/atypical squamous cells of undetermined significance and low-grade squamous intraepithelial lesions: a retrospective study.

The new Bethesda System (BS) terminology has opened a series of problems about the Abnormal/Atypical Squamous Cells of Undetermined Significance (ASCUS) and Low-Grade Squamous Intraepithelial Lesion (L-SIL) categories, particularly on their treatment and follow-up. Moreover in these field a non negligible portion of lesions progress to High-Grade Lesion (H-SIL). With the aim of comparing the data, we examined samples observed in our Ambulatories with 6-12 months follow-up.
