Abstract：
Pleomorphic adenomas (PA) are the most common type of salivary gland tumors. These slow-growing benign tumors most commonly involve the parotid gland, but can sometimes occur at atypical sites such as the submandibular or minor salivary glands. We describe an atypical case of pleomorphic adenoma with multicentric involvement of the parotid, the submandibular gland, and the parapharyngeal space in a 35-year-old male which mimicked a slow-flow malformation on magnetic resonance imaging (MRI). Diagnosis was confirmed on fine needle aspiration cytology, and conservative approach was opted for the patient in view of perioperative risks. This case highlights the uncommon multicentricity and atypical presentation of PA, challenging the initial differential diagnosis based on MRI features. It also underscores the importance of considering atypical presentations and utilizing accurate diagnostic tools like cytology for managing complex salivary gland tumors.
摘要：
多形性腺瘤（PA）是最常见的唾液腺肿瘤。这些生长缓慢的良性肿瘤通常累及腮腺,但有时可发生在非典型部位，如颌下腺或小唾液腺。我们描述了一个非典型的多形性腺瘤伴腮腺多中心受累的病例，颌下腺,以及一名35岁男性的咽旁间隙，该男性在磁共振成像（MRI）上模仿了慢流畸形。诊断通过细针穿刺细胞学检查得到证实，考虑到围手术期的风险,患者选择了保守方法.该病例突出了PA的不常见的多中心和非典型表现，基于MRI特征的初始鉴别诊断具有挑战性。它还强调了考虑非典型表现并利用诸如细胞学的准确诊断工具来管理复杂的唾液腺肿瘤的重要性。
