Fine needle aspiration cytology in the diagnosis of prostatic enlargements.

One hundred patients with enlarged prostate were subjected to fine needle aspiration cytology and histopathologic examination of prostate. The results have been found encouraging. The cytodiagnostic accuracy rate was 99 p.c. in identification of benign or malignant nature of the lesions and 94 p.c. in cytologic specific diagnosis (exactly similar to histopathologic diagnosis). The technique was simple, rapid, economical, reliable, easy to repeat and highly suitable for outpatients. The procedure can routinely be adopted in places where facilities for preparation of paraffin section do not exist or when quick diagnosis is required.

Role of rapid imprint cytology in the diagnosis of skin cancer and assessment of adequacy of excision.

Imprint cytotechnique was employed in 20 cases of maligant skin tumours (11 squamous cell carcinoma, 4 basal cell carcinoma and 5 malignant melanoma) to evaluate the reliability of the technique by comparing the results with histologic diagnosis. In ten cases margins of the excised tumours were also subjected to imprint and histopathologic studies to assess the clearance of malignancy. All the tumours were correctly diagnosed in imprint smears. Similarly 100% cytohistopathologic correlation was also obtained in the assessment of excisional margins of the tumours. The technique of imprint cytology may be employed for quick diagnosis of skin cancers and in assessment of clearance of surgical field during surgery.

Pathological review of melanotic neuroectodermal tumour of infancy in India.

Melanotic neuroectodermal tumour of infancy (MNETI) is a rare occurrence. Review of literature indicated 14 cases of MNETI encountered in India. The reported cases were observed in infants below one year of age. Males were affected more than the females. Except for one in the orbit, all the lesions were located in the maxilla. Histologically, lesions have been reported to be classical and benign in nature. Morphology of the tumours have been presented and discussed.

Ultrasound-guided fine needle aspiration cytology of malignant gallbladder masses.

OBJECTIVE: To determine the accuracy and reliability of ultrasound (US)-guided fine needle aspiration cytology (FNAC) over blind aspiration in gallbladder masses. STUDY DESIGN: We performed FNAC in 107 cases of carcinoma of the gallbladder; blind aspiration was done in 71 patients (66.36%) and US-guided aspiration in 36 (33.64%). In cases where FNAC after the first aspiration showed the aspirate to be inflammatory, acellular (inconclusive) or suspicious for malignancy, FNAC was repeated under US guidance. Diagnosis was later confirmed by histopathology in all cases. RESULTS: After the first aspiration, gallbladder malignancy was confirmed in 77 (71.96%) cases. Of these 77 cases, 34 underwent US-guided aspiration, and the remaining 43 underwent blind aspiration. Cases with inflammatory or acellular (inconclusive) aspirates or that were suspicious for malignancy after the first aspiration underwent a second aspiration under ultrasonic guidance. On the second aspiration of 30 cases, 16 (53.33%) proved to be of adenocarcinoma, 7 (23.33%) were suspicious for malignancy, 5 (16.66%) were inflammatory, and 2 (6.66%) were acellular. Diagnosis was later confirmed by histopathology in all cases. US-guided FNAC had diagnostic accuracy of 95% as compared to 60% on blind aspiration. There was no major complication or needle tract recurrence of the disease. CONCLUSION: US-guided FNAC is safe, rapid, reliable, cost-effective and accurate in diagnosing gallbladder carcinoma.
