Objectives: Histopathological study of bone tumours
to determine the spectrum of bone tumours at a
Medical teaching Hospital and to correlate it with
demographic features like age, sex of patients and
anatomical site of tumours. Material and Methods:
A retrospective and prospective study of all
histopathologically diagnosed bone tumours over a
period of 10 years was done. Patients were assessed
by clinical examination, radiological investigations,
histopathological examination and fine needle
aspiration cytology (FNAC) whenever available.
Results: A total of eighty-two cases of primary bone
tumours were recorded, of which benign tumours were
the most common 62 cases (75.61%) followed by
malignant tumours with 13 cases (15.85%) and 7 cases
(8.54%) of tumour-like lesions. FNAC diagnosis was
available in 26 cases (31.71 %) with 68.96 % benign
tumours, 17.24% malignant and 3.45% were tumour–
like lesions. The concordance and discordance rate of
histopathological diagnosis was 76.93% and 23.07
% respectively. On histopathological diagnosis, the
most common benign tumour was osteochondroma
34.15% followed by Giant cell tumour 19.51%.
Osteosarcoma was commonest malignant tumour
8.54%. Maximum number of bone tumours occurred
in 11-20 years of age and the male to female ratio
was 1.2:1. Conclusions: Bone tumours occurredpredominantly in the second decade of life with a
male preponderance. Osteochondroma was the most
common benign tumour followed by Giant cell
tumour and Osteosarcoma was the most common
malignant bone tumour
