Oral leiomyomas are rare, benign neoplasms of smooth muscle origin, presenting as a solitary, asymptomatic, nodular mass.
Here we present the case of a 54-year-old male with a lesion in the midline of his hard palate, which was diagnosed as a localized benign leiomyoma, along with a review of the recent literature.
Diagnosis of a leiomyoma must be based on the histopathological assessment of tissue as the clinical appearance is non-specific. The peak prevalence of head and neck leiomyoma is observed in the 4 and 5 decade of life with uncertain gender predilection. Histological features include interlacing fascicles of smooth muscle small cells with eosinophilic cytoplasm. Complete excision is usually curative and recurrence is rare.
Due to their rare nature, it is important that cases of oral leiomyoma can be reported in the literature to improve our understanding of this entity.
口腔平滑肌瘤是一种罕见的起源于平滑肌的良性肿瘤,表现为单个、无症状的结节状肿块。
在此,我们报告一例54岁男性患者,其硬腭中线处有一病变,经诊断为局限性良性平滑肌瘤,并对近期文献进行综述。
平滑肌瘤的诊断必须基于组织的组织病理学评估,因为其临床表现无特异性。头颈部平滑肌瘤的发病高峰出现在40至50岁,性别倾向不明确。组织学特征包括平滑肌小细胞的交织束状结构,细胞质嗜酸性。完整切除通常可治愈,复发罕见。
由于其罕见性,在文献中报告口腔平滑肌瘤病例对于增进我们对该疾病的了解很重要。
