title: Incidence of primary bone tumours and tumour like lesions in and around Dakshina Kannada district of Karnataka.
abstract: A total of 523 cases of primary bone tumours and tumour like lesions in and around Dakshina Kannada district of Karnataka were diagnosed over a period of 36 years. About 39% of these tumours were malignant and the remaining benign. Among the malignant tumours the highest incidence was of osteosarcoma (45.7%) followed by Ewing's sarcoma (19.4%). Osteochondroma was the most frequent in the benign tumour category (30.3%). Peak incidence of tumour was in the 2nd and 3rd decade of life with a male preponderance. The most commonly affected bones were femur, tibia and humerus in that order. Results indicate a significantly higher incidence of primary bone tumours in this part of India.
