Angiomatous antrochoanal polyps : challenge in diagnosis

الملخص EN

Epistaxis is a common complaint seen in the younger population.

Its etiology is typically from the anterior nares, although we present a case of epistaxis from an uncommon source.

Diagnosis of bleeding nasal mass is varied from benign to malignant lesions.

Angiomatous antrochoanal polyps (AAP) are one of the causes but it is rare and the diagnosis is challenging as it mimic other nasal mass especially nasopharyngeal angiofibroma (NA).

There are a lot of similarities of clinical presentations, between imaging and histopathological findings between these two which made the diagnosis even more difficult.

A correct diagnosis is extremely important as although they have similar clinical presentations, the management is different.

Here we report a case of a young lady with significant epistaxis which was initially diagnosed as NA but with a final revised diagnosis of AAP.
