title: Malignant orbital tumours: observation in north Bengal.
abstract: Sixty-one cases of malignant orbital tumours were analysed retrospectively in relation to the incidence, age, sex, race, anatomical site of origin of the tumours and their histological types in North Bengal. Retinoblastoma is the commonest type (65%) followed by adenocarcinoma (10%), squamous cell and basal cell carcinoma (8.8% each). Other tumours were rarely encountered.
