Abstract:
Leiomyosarcomas (LMSs) of the head and neck are an extremely rare entity. Of all smooth muscle tumors, 4%-10% occur in the head and neck and only 0.06% in the oral cavity. Because of its infrequency, it has been associated with both delayed diagnosis and misdiagnosis. Here, we report the clinicopathological findings of a case of primary LMS of the soft palate in a 42-year-old male patient with an emphasis on the judicious use of ancillary diagnostic modalities to arrive at a definitive diagnosis. Intraorally, LMSs present as painless, lobulated, fixed masses of the submucosal tissues in middle-aged or older individuals. The treatment modalities and lymph nodal dissection criteria are dissimilar to more common oral carcinomas. Hence, definitive diagnosis is necessary.
摘要:
头颈部平滑肌肉瘤(LMS)是一种极为罕见的实体。在所有平滑肌肿瘤中,4%-10%发生在头颈部,仅0.06%发生在口腔。由于它的频率不高,它与延迟诊断和误诊有关。这里,我们报告了一例42岁男性患者的原发性软腭LMS的临床病理发现,重点是明智使用辅助诊断方法以得出明确的诊断.口头,LMS呈现为无痛,分叶状,中老年人粘膜下组织的固定肿块。治疗方式和淋巴结清扫标准与更常见的口腔癌不同。因此,明确的诊断是必要的。
