Abstract
Aggressive psammomatoid ossifying fibromas (APOFs) represent a subgroup of related fibro-osseous lesions that appears to be unique to the nasal cavity, paranasal sinuses, and orbit. These rare lesions are characterized by distinctive histomorphologic features and a tendency to affect younger patients. Histologically they are benign, but clinically they are locally aggressive. We report the case of a 15-year-old boy who had a large APOF in the left ethmoid and sphenoid sinuses. The location of this tumor made this case unusual.

Abstract
Cementoossifying fibroma is a rare nonodontogenic tumor of the periodontal membrane that arises from the mesodermal germ layer. This nonneoplastic, locally destructive tumor has occurred as an osseous lesion in the mandible, the maxilla, the zygoma, all the paranasal sinuses, and the orbital and petromastoid regions. It has occurred as an extraosseous lesion in the gingiva and the auricle. The diagnosis requires correlating a variety of clinical, radiologic, and histologic factors. The recurrence rate is high, particularly for lesions in the paranasal sinuses. Surgical management via a local excision as wide as possible is suggested. We describe the case of a 32-year-old woman with an isolated cementoossifying fibroma of the right ethmoid bulla, and we review the diagnosis, differential diagnosis, and management of this tumor.

Abstract
Sinonasal lymphomas are uncommon malignancies. They are difficult to differentiate from carcinomas, and immunohistochemistry is needed to make the diagnosis. We describe an unusual case of a T cell lymphoma that involved only the paranasal sinuses in a middle-aged man. The patient presented with a complete loss of vision in one eye and lateral rectus muscle palsy, but no nasal symptoms.
