PREVALENCE OF INTRAORBITAL NEOPLASMS- A RETROSPECTIVE STUDY FOR SEVEN YEARS
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 20
Abstract
BACKGROUND A large variety of tumours are seen to arise from the orbit. These can be malignant, benign or intraepithelial neoplasms. Studies were conducted on these tumours and their prevalence in different parts of the world. The prevalence of the individual tumours in different regions of world are different. Metastatic tumours are the most common in a study, while basal cell carcinoma tops the chart in another. Rhabdomyosarcoma is common in some studies, while lymphoma is one of the commonest in some places. This study was conducted to learn the pattern in Kerala and compare it with the patterns in other regions. MATERIALS AND METHODS The descriptive study was conducted in the Regional Institute of Ophthalmology, Thiruvananthapuram. All tumours involving the orbits that were seen in the centre from 2010 September to August 2017 were included. RESULTS Benign tumours constitute the majority among which nevi, angiomas and squamous papilloma are the commonest. The prevalence of benign and malignant tumours is different from studies conducted in some other centres. For example, metastatic tumours and basal cell carcinoma are the commonest among the malignant tumours in the studies from some centres, while squamous cell carcinoma and lymphoma were the commonest in our study. However, similar patterns of prevalence were seen in studies conducted in centres closer to our centre. CONCLUSION Distribution pattern of orbital tumours in Kerala are comparable to that in some other Indian states and neighbouring countries like Pakistan. This may be due to factors like viral infections like Human Papilloma Virus, terrestrial radiation, genetic factors etc.
