ABSTRACT
Background:Theintra-operative cytology in the evaluation of central nervous system (CNS) lesions isasimpleandrapidtechnique, and a usefultool. There is not much literature available on the value of crush cytology during the operation. The current study was planned to assess the feasibility and efficacy of intra-operative squash cytology as standalone method in the rapid intra-operative diagnosis of intracranial tumor.Methods:A prospective observational study was carried out in the department of neurology in collaboration with department of pathology, Medanta: The Medicity, Gurugram, for a period of six months from January 2019 toJune 2019, on randomly selected 60 patients, aged: 18 years and above. Two to three tissue bits, from different sites of the mass, were taken to prepare squash cytology smear.Results:Out of 60 patients operated, 54 had neoplastic and 6 had non-neoplastic lesions. Neoplastic benign lesions were observed in 41 patients and neoplastic malignant lesions were diagnosed in 13 patients. There was 17.67% offering a wrong diagnosis on crush cytology. Out of the 13 cases of meningioma, there was a discrepancy in 3 (three) cases.Conclusions:Crushcytologyisausefuladjuncttothediagnosisinneurosurgicalpractice.Thisstudysuggests and confirms the reliability of squash cytology, but further multicentre studies with larger number of patients may help to decide its use in clinical practice.
ABSTRACT
Background: The presence of mass in the nose may seem to be a simple problem; however it raises several issues about the differential diagnosis. The aim of this study is to evaluate the histological profile of nasal masses in the environment. Methods: This is a retrospective and prospective study of nasal masses during a period of five years of patients presenting to the clinician in our hospital. Results: A total of 90 patients were analysed age ranging from 3 to 80 years. Majority of patients were in the second decade. Sex wise distribution showed a male to female ratio of 2.2:1. The main presenting symptom was nasal obstruction seen in 53.30% patients, while proptosis was seen only in malignant lesion. Among a total of 90 lesions in the nasal cavity 81.1% were benign, 15.5 % were malignant and 3.3% were inadequate sample The commonest non neoplastic lesion was nasal polyp which comprised about 83.33% followed by rhinoscleroma, while the commonest benign neoplastic lesion was papilloma and comprised about 42.10% and squamous cell carcinoma was the most common malignant neoplastic lesion in the nasal cavity and comprised about 42.85%. Most patients with benign lesion were in the second decade. Malignant lesions occurred mainly after fifth decade, while inadequacy of sample was seen in the second decade. Conclusion: Males are more commonly affected then females. Nasal obstruction is the commonest symptom Simple inflammatory nasal polyp is still the commonest histological pattern seen while papilloma being the most common benign lesion and squamous cell carcinoma the most common malignant lesion.
