A rare case of sinonasal ameloblastoma presenting with complete nasal obstruction

Sinonasal Ameloblastoma: A Case Report and a Review of Gnathic Lesions That Occur in the Sinonasal Tract

“…[2][3][4][5][6][7][8][9][10] Between 2% and 10% of AMs are found in extragnathic sites. 10 Sinonasal AM is a rare extragnathic variety of AMs. 1,7,[10][11][12][13][14][15][16][17] The largest case series, conducted by Schafer et al, 5 described 24 cases of SNAM seen over 40 years.…”

“…10 Sinonasal AM is a rare extragnathic variety of AMs. 1,7,[10][11][12][13][14][15][16][17] The largest case series, conducted by Schafer et al, 5 described 24 cases of SNAM seen over 40 years. The diagnosis is typically used for AMs that present mostly within the sinonasal tract, and exclusion of truly gnathic lesions requires radiology.…”

“…3,5,9,10,18 Patients present with progressive nasal obstruction, chronic sinusitis, epistaxis, rhinorrhea, hemifacial paresthesia, and facial pain. 2,[9][10][11]15,19 The symptoms at presentation depend on the size and location of the tumor. 15,16 The nonspecific nature of the symptoms often leads to a delay in diagnosis.…”

Ameloblastoma of the Sinonasal Tract: Report of a Case with Clinicopathologic Considerations

“…AM is a slow growing, locally aggressive tumor, usually arising in the jaws and frequently associated with an unerupted tooth [1–10]. It may arise from the epithelial lining of a dentigerous cyst or from the remnants of the dental lamina and enamel organ [5, 7, 20].…”

“…Surgical excision is the treatment of choice in all cases. Recently, endoscopic management of AMs has resulted in less radical surgical approach with decreased morbidity and better tumor control [8–10, 12, 14, 16–19]. However, prognosis is based on the extension of the lesion and on adjacent structures involved rather than on origin of the lesion.…”
