Advances in the understanding of lung cancer biology have led to observations that specific genetic changes occur in premalignant dysplasia. These observations have occurred predominantly in molecular studies of resected lung tumors and consequently, they may not be fully representative of those biological abnormalities characterizing premalignant lesions in individuals without overt lung cance...

background and objective: cutaneous cytology is the study of scraping or smears obtained from skin lesions. although not commonly employed, cutaneous cytology has been a useful tool for clinicians due to simplified procedures and high sensitivity and specificity of presurgical clinical diagnosis of common types of skin tumors. this investigation was conducted to study usefulness of cutaneous cy...

Abstract A 14-year-old boy presented with left preauricular painless swelling of 10 months' duration. Local examination revealed a 3 × 2-cm, firm, nodular, nonmobile mass in the area, just front tragus. Fine needle aspiration yielded paucicellular smears comprising singly scattered histiocyte/myofibroblast-like spindle cells and occasional giant cells. It was reported as benign mesenchymal lesi...

  Five hundred eighty patients underwent diagnostic flexible fiberoptic bronchoscopy: during June 1988 to March 1993 at the bronchoscopy center of Kerman university of medical sciences. Seventy six specimens were obtained from patients with bronchogenic carcinoma and 155 from patients with benign disease of the lung. The efficiency of brushing and washing techniques was compared with forceps b...

Background and Aim: Fine Needle Aspiration Cytology (FNAC) plays an important role in the diagnosis of tuberculous inflammation prevents unnecessary surgery. Cytodiagnosis tuberculosis depends on demonstration epithelioid cell granuloma caseous necrosis with or without Langhans type giant cells. Present study was done to assess usefulness cytological granulomatous lesions.Material Methods: The ...
