BACKGROUND
Myoepitheliomas account for less than 1% of salivary gland tumors. They mostly affect the parotid glands of adults during the third to fifth decades.
CASE PRESENTATION
A 10-year-old Indian boy reported a small swelling in the roof of his mouth of 10 days' duration. History revealed that the lesion was painless and not associated with bleeding or pus discharge. On examination, a purplish well-circumscribed growth was noted on his posterior hard palate. Magnetic resonance imaging was suggestive of a well-encapsulated hemangioma. An excisional biopsy was performed and histopathology along with immunohistochemistry analysis showed that the lesion was a spindle cell variant of benign myoepithelioma.
CONCLUSION
Palatal myoepitheliomas are rare and their occurrence in young individuals is rarer.
背景
肌上皮瘤占涎腺肿瘤的比例不到1%。它们主要影响30至50岁成年人的腮腺。
病例报告
一名10岁的印度男孩报告说，他口腔顶部有一个持续10天的小肿块。病史显示，该病变无痛，与出血或脓性分泌物无关。检查时，在其硬腭后部发现一个边界清晰的紫色肿物。磁共振成像提示为一个包膜完整的血管瘤。进行了切除活检，组织病理学及免疫组织化学分析显示该病变为良性肌上皮瘤的梭形细胞变体。
结论
腭部肌上皮瘤罕见，在年轻人中发生则更为罕见。
