Abstract
1. Two cases of haemangioma of the patella are reported.
2. In one case pain alone brought the patient for treatment; in the other, a pathological fracture was the first symptom.
3. In neither case was a firm diagnosis made before excision and histological examination of the patella.
4. In each case a good result followed removal of the patella: this is probably the best method of treatment.
5. The literature relating to haemangioma of bone and to tumours of the patella is briefly reviewed.
