Maxillary Ameloblastoma: A Potentially Lethal Neoplasm
Archives of Otolaryngology - Head and Neck Surgery, 1989Ameloblastomas are benign tumors derived from the odontogenic apparatus. Of these tumors, 80% originate in the mandible, while 20% originate in the maxilla. Six cases of maxillary ameloblastoma treated at the UCLA hospitals are presented; four of these cases showed extensive and destructive tumor growth involving vital structures, including the orbit ...

Oncocytic carcinoma of the maxillary sinus: a rare neoplasm
European Archives of Oto-Rhino-Laryngology, 2006Oncocytic neoplasms are tumors composed of oncocytes (i.e., epithelial cells with a large cytoplasm that is rich in mitochondria). Most cases are benign and originate from the major salivary glands, while the minor salivary glands are rarely involved. Occurrence of oncocytic carcinoma (or malignant oncocytoma) within the sinonasal tract is an unusual ...

Extended endoscopic approaches to the maxillary sinus
Journal of Laryngology and Otology, 2020Objectives Treatment of inflammatory and neoplastic disease in the maxillary sinus, pterygopalatine and infratemporal fossae requires appropriate surgical exposure. As modern rhinology evolves, so do the techniques available.

Mesenchymal phosphaturic neoplasm in the maxillary sinus: a case report
International Journal of Oral and Maxillofacial Surgery, 2010The authors describe a case of oncogenic osteomalacia due to a mesenchymal phosphaturic tumour in the maxillary sinus. This is a paraneoplastic syndrome in which a tumour produces a peptide hormone-like substance (phosphatonin) that causes a urinary loss of phosphates resulting in a debilitating systemic condition. In this case, the patient experienced

Clear Cell Odontogenic Carcinoma: A Rare Neoplasm of the Maxillary Bone
Journal of Oral and Maxillofacial Surgery, 2014Clear cell odontogenic carcinoma (CCOC) is an extremely rare neoplasm, with only 74 cases in the English-language literature. It displays a propensity for the mandible, most commonly presenting in the fifth to seventh decades. Histopathologically, CCOC is characterized by sheets and islands of vacuolated and clear cells.

Giant Ethmoid Sinus Osteoma Protruding into the Maxillary Sinus.
The Journal of craniofacial surgery (Print), 2020Ethmoid sinus osteomas are rare, benign, encapsulated neoplasms of the paranasal region. They can lead to various complications such as sinusitis, orbital cellulitis, proptosis, and diplopia.

SMARCB1 (integrase interactor 1) is a tumor suppressor gene encoded on chromosome 22q11.2 that encodes a core subunit of SWI/SNF chromatin remodeling complexes and plays a critical role in regulating gene expression and chromatin structure. We describe a case of SMARCB1 (integrase interactor 1)-deficient sinonasal carcinoma of the left maxillary sinus ...
