This week's artwork was donated by Lonny, a pediatric cancer patient who received treatment at The Children's Hospital of Philadelphia . Endoscopic resection of a recurrent sinonasal hemangiopericytoma. Varicella mimicking pulmonary metastasis in a patient with rhabdomyosarcoma. She was treated by a right lateral rhinotomy with total removal of the tumor and the subsequent clinical course was good.
Carcinomas arising in pre-existing sinonasal papillomas of the nasal septum are rare.
To our knowledge only one case has been reported. We report two cases of carcinomas occurring in septal papillomas. In the first case a carcinoma developed in an exophytic papilloma 16 years after the first operation for a papilloma. In the second case a carcinoma was present at the first presentation within an inverted papilloma, and a metastasis had also developed. In the second case HPV type 18 was found in the nasal lesion as well as in the metastasis.
