Odontogenic myxomas (OMs) are nonencapsulated rare benign tumors that can occur in gnathic bones. They are locally invasive and have a high recurrence rate. Radiologically, OMs show a multilocular (in the majority of cases) or unilocular radiolucency, with either distinct or poorly defined margins. Histopathologically, OMs are characterized by spindle-, wedge-, or stellate-shaped cells loosely arranged in an abundant mucoid background. Myxomas are mainly asymptomatic. Radical surgery, excision, and enucleation followed by curettage of the surrounding bony tissue have all been advocated as treatment options. This study presents a successful case of conservative treatment of OMs with a 5-year follow-up.
牙源性黏液瘤（OMs）是一种罕见的非包膜性良性肿瘤，可发生于颌骨。它们具有局部侵袭性，复发率高。在影像学上，牙源性黏液瘤表现为多房性（大多数情况下）或单房性透射区，边界清晰或不清晰。组织病理学上，牙源性黏液瘤的特征是梭形、楔形或星状细胞松散地排列在丰富的黏液样背景中。黏液瘤主要无症状。根治性手术、切除、摘除并刮除周围骨组织均被推荐为治疗选择。本研究报告了一例牙源性黏液瘤保守治疗成功且随访5年的病例。
