Glomus tumours

چکیده
Pericytic / perivascular neoplasms have traditionally been dominated by haemangiopericytoma. However, it is now recognized that the latter diagnostic category subsumes a wide variety of tumour types which share the presence of thin-walled branching blood vessels. If such lesions are otherwise classified, there remains only a small group of spindle cell lesions designated as haemangiopericytoma, although they have no evident relationship to pericytes, and may be more closely related to solitary fibrous tumour (see Chapter 2).
