giant cell angiofibroma

Tuesday 11 October 2005

Giant cell angiofibroma seems most often to arise in the head and neck region (predominantly orbit) of adults and which, with the passage of time.

It may well prove to be a variant of solitary fibrous tumour characterized by prominent multinucleate giant cells and lipofibromatosis.

It is a rare tumour occurring predominantly in the hands or feet of infants and young children.

it shows a high rate of local recurrence and consists of a complex admixture of mature adipose tissue and a highly cellular, often primitive-looking fibroblastic component arranged in a septal distribution.
