Abstract
The purpose of this study is to investigate the causes and characteristics of the aggressive solitary bone lesion in patients over the age of forty.
Over a four year period, 318 patients over the age of forty were referred to our institution with what we would define as an aggressive solitary bone lesion. Further investigation and diagnostic biopsy as appropriate were performed in all patients. The lesions were then defined according to their radiological appearance, pathology and site. The nature of these lesions was then subdivided into several broad groups. A diagnosis of primary bone sarcoma was found in 30% of these lesions. Plasmacytoma, lymphoma and metastases accounted for 13% each. Benign bone tumours, infection and non-oncological diagnoses accounted for 9%, 6% and 16% of lesions respectively.
Aggressive solitary bone lesions are often due to primary bone sarcomas. Metastases from a previously unrecognised primary malignancy account for less than one sixth of lesions. This study emphasises the need for appropriate investigation and biopsy of the aggressive solitary bone lesion.
