INTRODUCTION Post-operative excessive bleeding can be due to various causes, which may platelet deficiency, both quantitative and qualitative, vascular disorder, clotting factor defects and excessive fibrinolysis. Rarely can be due to some undiagnosed malignant tumours. Angiosarcoma of bone is an exceedingly rare primary bone malignancy. We report an interesting and rare case of an intraosseous...

INTRODUCTION An aneurysmal bone cyst is a benign but often rapidly expanding osteolytic multi-cystic osseous lesion that occurs as a primary, secondary, intra-osseous, extra-osseous, solid or conventional lesion. It frequently coexists with other benign and malignant bone tumors. Although it is considered to be reactive in nature, there is evidence that some aneurysmal bone cysts are true neopl...

Aneurysmal bone cyst (ABC) is a benign, expansile, non-neoplastic lesion of the bone, characterized by channels of blood and spaces that are separated by fibrous septae. Giant ABC is an uncommon condition and can be difficult to handle because of the destructive effect of the cyst on the bones and the compressive effect on the nearby structures, especially in weight-bearing bones of the body. W...

BACKGROUND Aneurysmal bone cysts are relatively uncommon in the facial skeleton. These usually affect the mandible but origin from the coronoid process is even rarer. To the best of our knowledge, this is the first reported case of a coronoid process aneurysmal bone cyst presenting as temporal fossa swelling. CASE PRESENTATION A 17 year old boy presented with a progressively increasing swelli...

Aneurysmal bone cysts are expansile osteolytic bone lesions that can manifest clinically as lameness, pain and swelling. In humans, aneurysmal bone cysts are considered benign tumours that have been classified as primary or secondary to a previous coexisting lesion. Local recurrence after treatment or malignant transformation has been reported in both humans and in a dog. Different treatment op...
