Abstract

Myoepitheliomas are rare benign tumours that affect the exocrine glands and are sporadically located in the salivary glands. The most common location of myoepithelioma in the oral cavity is the parotid gland and it is seldom encountered in the palate. The diagnosis of this entity is challenging since its clinical presentation may resemble those of more common neoplasms, rendering a complex histopathological diagnosis. The aim of the present case report is to describe an unusual case of myoepithelioma of the soft palate in a male patient, which developed as an asymptomatic, slowly growing mass. The tumour was assessed with histopathological examination and the diagnosis was verified via immunohistochemistry. Finally, the treatment included surgical resection of the tumour and no signs of recurrence were noted 2.5 years after the surgical procedure. Early diagnosis and treatment plays an important role in the prognosis of this pathological entity.

摘要

肌上皮瘤是一种罕见的良性肿瘤,可累及外分泌腺,散发性地位于唾液腺。口腔中肌上皮瘤最常见的部位是腮腺,很少见于腭部。该实体的诊断具有挑战性,因为其临床表现可能类似于更常见的肿瘤,从而导致复杂的组织病理学诊断。本病例报告的目的是描述一名男性患者软腭肌上皮瘤的罕见病例,该肿瘤表现为无症状、生长缓慢的肿块。通过组织病理学检查对肿瘤进行评估,并通过免疫组织化学验证诊断。最后,治疗包括手术切除肿瘤,手术后2.5年未发现复发迹象。早期诊断和治疗对该病理实体的预后起着重要作用。
