Polypoid sinusitis mimicking orbital malignancy.
A 15-year-old boy developed a rapidly progressive exophthalmos of 6 mm within two months. Radiologic evidence showed bony erosion, a palpable firm mass in the right upper eyelid, and mass blocking the right nares. This tumor was found to be polypoid sinusitis emanating through the lamina papyracea.
