Masson's pseudotumour of the ethmoid sinus - a case report.
OBJECTIVE
We report a case of Masson's pseudotumour or intravascular papillary endothelial hyperplasia presenting in the ethmoid sinus.


METHODS
We present a diagnostically challenging case of Masson's pseudotumour of the ethmoid sinus presenting with persistent epistaxis and a review of the available literature.


CONCLUSIONS
Intravascular papillary endothelial hyperplasia is a benign, reactive lesion first described by the French pathologist Pierre Masson in 1923. It can lead to diagnostic uncertainty due to its close resemblance clinically, radiologically and histopathologically to angiosarcoma.
