| haemangioma | <cardiology, dermatology, embryology, physiology> A haemangioma or arteriovenous malformation is a tangle of abnormal vessels that forms an abnormal communication between the arterial and venous systems. most are congenital and result from improperly formed angioblastic tissue in the foetus. If large enough, they may produce a shunt of sufficient magnitude to raise the cardiac output. Arteriovenous malformations may occur in the brain, brainstem and spinal cord, where they may cause headaches, seizures or bleeding (subarachnoid haemorrhage). Red or purple-coloured vascular skin markings that develop shortly after birth. most are usually painless and benign. Some lesions (cavernous haemangiomas) will disappear or become harder to see as the child approaches school age. Localised steroid injections have been used successfully to reduce the size of a birthmark. (18 Nov 1997) |

| haemangioma of bone | <radiology> Lytic bone lesion, can cross joint spaces and interosseous membranes Findings: vertebral body: vertical striations (ivory), skull: sunburst or sunrise, long bone: soap bubble or honeycomb, which may surround a joint see also: Mafucci syndrome (12 Dec 1998) |
| haemangioma of vertebrae | <radiology> Cavernous type commonly found, 10% in autopsy series with the vast majority being small, asymptomatic and unable to be seen on plain films, most often in lumbar region and singular, complications: compression fractures (occasionally with cord compression), chronic haemorrhage to blockage of spinal canal X-ray: slight loss of density of vertebral body, vertically striped orientation of bone trabeculae (corduroy cloth) which may extend into the pedicle, occasionally with posterior bulging, cortical margins usually intact see also: haemangioma of bone (12 Dec 1998) |
| haemangioma planum extensum | A benign, flat, cutaneous haemangioma of considerable size. (05 Mar 2000) |
| haemangioma, cavernous | A vascular tumour preponderantly composed of large dilated blood vessels, often containing large amounts of blood, occurring in the skin, subcutaneously, or both, and also in many viscera, particularly the liver, spleen, pancreas, and sometimes the brain. The typical superficial lesions are bright to dark red in colour; deep lesions have a blue colour. A cavernous haemangioma in the skin extends more deeply than a capillary haemangioma and is less likely to regress spontaneously. (12 Dec 1998) |
| haemangioma-thrombocytopenia syndrome | <syndrome> Thrombocytopenia caused by sequestration and destruction of platelets in a large cavernous haemangioma, usually seen in infants, rare in adults (12 Dec 1998) |
| haemangiomatosis | A condition in which there are numerous haemangiomas. (05 Mar 2000) |
| capillary haemangioma | <dermatology> Red or purple-coloured vascular skin markings that develop shortly after birth. Most are usually painless and benign and sharply demarcated from surrounding skin, usually located on the head and neck, and grow rapidly. It is caused by proliferation of immature capillary vessels in active stroma, and is usually present at birth or occurs within the first two or three months of life. Some lesions (cavernous haemangioma) will disappear or become harder to see as the child approaches school age. Localised steroid injections have been used successfully to reduce the size of a birthmark but generally they undergo spontaneous regression and involution without scarring and normally require no treatment.

| racemose haemangioma | Dilation of a group of blood vessels owing to congenital malformation with arteriovenous shunting. Synonym: cirsoid varix, racemose aneurysm, racemose haemangioma. (05 Mar 2000) |
| verrucous haemangioma | A variant of the angiomatous nevus, appearing at birth or in early childhood, situated on the lower extremities with bluish-red nodules and warty surface; they enlarge and sometimes have satellite lesions. (05 Mar 2000) |
| cavernous haemangioma | <dermatology> Red or purple-coloured vascular skin markings that develop shortly after birth. most are usually painless and benign. Some lesions (cavernous haemangiomas) will disappear or become harder to see as the child approaches school age. Localised steroid injections have been used successfully to reduce the size of a birthmark. (16 Mar 1998) |
| cavernous haemangioma of liver | <radiology> Ultrasound: increased echogenicity, CT: decreased density, enhances from periphery, becomes isodense, may enlarge during pregnancy, in kids: most common benign liver tumour, increased morbidity/mortality, classic triad: hepatomegaly, cut. Haemangiomas, congestive heart failure, with or without liver bruit, may rupture leading to haemoperitoneum, may regress spontaneously (as may haemangioendothelioma) (12 Dec 1998) |
| sclerosing haemangioma | <tumour> A benign lung or bronchial lesion, often subpleural, sometimes multiple, which forms hyalinised connective tissue. Synonym: fibrous histiocytoma. (05 Mar 2000) |
| senile haemangioma | <tumour> A red papule due to weakening of the capillary wall, seen mostly in persons over 30 years of age. Synonym: cherry angioma, De Morgan's spots, ruby spots. (05 Mar 2000) |
| spider haemangioma | spider angioma |
| strawberry haemangioma | <oncology, tumour> Red or purple-coloured vascular skin markings that develop shortly after birth. most are usually painless and benign. Some lesions (cavernous haemangiomas) will disappear or become harder to see as the child approaches school age. Localised steroid injections have been used successfully to reduce the size of a birthmark. (27 Sep 1997) |
