Extragnathic odontogenic sinonasal myxoma with mitotic features

Area of Science:

• Otolaryngology
• Pathology
• Medical Imaging

Background:

• Sinonasal myxomas are rare tumors.
• The diagnostic criteria for sinonasal myxoma, particularly regarding mitotic activity, are debated.
• Accurate diagnosis is crucial for effective treatment and patient management.

Purpose of the Study:

• To present the first documented evidence of mitotic figures in a sinonasal myxoma.
• To discuss the implications of mitotic activity in the diagnosis of sinonasal myxoma.
• To highlight the clinical presentation and management of extensive sinonasal myxoma.

Main Methods:

• Case report of a 37-year-old gentleman with sinonasal myxoma.
• Preoperative evaluation using medical imaging.
• Surgical intervention including Functional Endoscopic Sinus Surgery (FESS) and Caldwell-Luc antrostomy.
• Histopathological examination of the resected specimen.

Main Results:

• The study presents the first documented evidence of mitotic figures in a sinonasal myxoma.
• Preoperative imaging revealed significant sinonasal obstruction and maxillary sinus involvement.
• The patient underwent successful surgical treatment with no recurrence at follow-up.

Conclusions:

• The presence of mitotic figures is an unusual, yet documented, feature in extensive sinonasal myxoma.
• This finding contributes to the ongoing debate regarding the diagnostic criteria for sinonasal myxoma.
• Effective surgical management led to a favorable outcome for the patient.
