: Epithelial-myoepithelial carcinoma (EMC) is a rare, low-grade malignant tumor of the salivary glands. It is characterized by a low malignancy potential, as indicated by its low rate of lymph node involvement and distant metastasis, and has a local recurrence rate of approximately 50%. Due to the rarity of EMC and the limited data available in the literature, there are no established treatment or follow-up guidelines. : We report the case of an 83-year-old man who presented with swelling in the left submandibular region, occurring 9 years following an initial diagnosis of EMC in the ipsilateral parotid gland. After radiological examinations and an ultrasound-guided fine-needle aspiration biopsy, the patient underwent surgical excision of the lesion with a histological diagnosis of recurrence/metastasis of low-grade epithelial-myoepithelial carcinoma. : This is the first documented case of loco-regional lymph node metastasis 9 years after an initial diagnosis of EMC of the parotid gland. Based on our experience, EMC of the parotid gland, even when diagnosed at an early stage, seems to require a long follow-up period.
上皮-肌上皮癌(EMC)是一种罕见的涎腺低度恶性肿瘤。其特点是恶性潜能低,淋巴结受累率和远处转移率低,局部复发率约为50%。由于EMC罕见且文献中的数据有限,目前尚无既定的治疗或随访指南。
我们报告了一例83岁男性患者,其在同侧腮腺初次诊断为EMC 9年后出现左下颌下区肿胀。经过影像学检查和超声引导下细针穿刺活检,患者接受了病变的手术切除,组织学诊断为低度上皮-肌上皮癌复发/转移。
这是腮腺EMC初次诊断9年后发生局部区域淋巴结转移的首例文献记载病例。根据我们的经验,腮腺EMC即使在早期诊断,似乎也需要较长的随访期。
