Diffuse cavernous haemangioma complicated with regional osteoporosis.

Capillary and cavernous haemangiomas are the most common benign soft tissue tumours of infancy. Cavernous haemangiomas have larger vascular channels and frequently exist in deep dermal tissues. Many haemangiomas require no special treatment. Development of complications such as cardiac failure, malignant change, ulceration and infection are indications for intervention. In this report we present an 11-year-old girl with a pathological fracture after a minimal trauma that might be a result of secondary regional osteoporosis due to diffuse cavernous haemangioma.
