Nasal haemangiopericytoma.
Haemangiopericytoma is an uncommon vascular tumour frequently diagnosed with difficulty. The immunohistochemical findings of strong positivity to vimentin together with other diagnostic features (histological and ultrastructural) improves the certainty of its diagnosis. We report a case arising in the nose and outline diagnostic problems especially relating to histopathology.
