Abstract：
UNASSIGNED: The parotid is the largest salivary gland and is located anteriorly to the sternocleidomastoid muscle and laterally to the ramus of the mandible. Neoplasms in this gland are relatively rare, with 80% being benign and 20% malignant, primarily represented by mucoepidermoid carcinoma. In the head and neck region, lymphoepithelial carcinoma (LEC) accounts for 0.4% of malignant salivary gland tumors.
UNASSIGNED: A 35-year-old man with no previous comorbidities was admitted to a Head and Neck Surgery Specialty Service for a painless right cervical mass of uncertain growth. Extensive diagnostic investigation revealed involvement of the contralateral parotid, associated with systemic lymph node enlargement. Thus, adjuvant radiotherapy was decided by the treating team.
UNASSIGNED: This case confirms the heterogeneous features and distinctive behavior that the disease can present, as seen with bilateral parotid LEC.

摘要：
■腮腺是最大的唾液腺，位于胸锁乳突肌的前方，并位于下颌骨的支的侧面。该腺体中的肿瘤相对罕见，80%是良性的，20%是恶性的，主要表现为粘液表皮样癌。在头部和颈部区域，淋巴上皮癌（LEC）占恶性唾液腺肿瘤的0.4％。
一名没有合并症的35岁男子因生长不确定的无痛右宫颈肿块而进入头颈外科专业服务机构。广泛的诊断调查显示对侧腮腺受累，伴有全身淋巴结肿大。因此，辅助放疗由治疗团队决定。
■该病例证实了该疾病可以呈现的异质性特征和独特行为，如双侧腮腺LEC所见。
