Fine-needle aspiration cytology of solitary thyroid nodules: how far can we go in rendering differential cytologic diagnoses?

Fine-needle aspiration cytology (FNAC) is a diagnostic tool used in the clinical workup of solitary thyroid nodules; however, differential cytologic diagnosis of these nodules often is challenging. With the goal of identifying cytologic findings that could improve predictions regarding the presence of neoplastic lesions, the authors performed a retrospective review of cases in which FNAC led to diagnoses of solitary cellular nodules or cellular microfollicular lesions at two university hospitals. FNAC smears associated with cases for which surgical specimens subsequently were obtained were reviewed. FNAC accurately detected follicular neoplasms in 76% of cases at one hospital and in 67% of cases at the other. In the current report, the cytologic findings made in these cases are reevaluated, and the potential diagnostic contribution of available clinical data is discussed.

A tubulopapillary adenoma of the gallbladder in a child of 3 years.

Adenoma is the most frequent type of gall-bladder (GB) neoplasm; however, GB neoplasms are unusual and unsuspected diagnoses in childhood. The average patient age is 50 +/- 16.3 years. We present a case of tubulopapillary adenoma of the gallbladder in a 3-year-old girl. She was admitted to the hospital with a 6-month history of abdominal pain and nausea and vomiting. Ultrasonography (USG) revealed an echogenic soft tissue lesion in the lumen of the GB. She underwent cholecystectomy. A tubulopapillary adenoma and adenomatous hyperplasia of the GB were diagnosed histologically. According to the literature, this is the youngest patient found to have gallbladder adenoma.

Preoperative brush and impression cytology in ocular surface squamous neoplasms.

OBJECTIVE: Preoperative cytologic diagnoses of ocular surface squamous neoplasms were evaluated and compared with histologic diagnoses. STUDY DESIGN: Impression cytology (Millipore filter paper) and brush cytology were applied to 32 patients who had conjunctival neoplasms. Papanicolaou-stained cytologic preparations and hematoxylin and eosin-stained histologic sections were examined by light microscopy. RESULTS: The brush technique was used on 27 patients; impression cytology was applied in 5 cases. Cytologic and histologic diagnoses were concordant in 26 cases. Squamous cell carcinoma or carcinoma in situ was diagnosed in 18 and dysplasia in 4 cases. Squamous metaplasia and normal-appearing conjunctival epithelial cells were diagnosed cytologically in four cases; of those histologic diagnoses, one was pterygium and three, conjunctival nevus. Four cases revealed discrepancies between the cytologic and histologic preparations. There was one false positive result, and one case was subconjunctival invasion of basal cell carcinoma of the eyelid. CONCLUSION: Impression and brush cytology are fast, cost-effective, reliable and noninvasive diagnostic tools for ocular surface squamous neoplasms. However, the brush technique has several advantages over impression cytology.
