Abstract

Head and neck tumors in adults present a broad differential diagnosis, particularly when considering malignant neoplasms that require prompt diagnosis and intervention. We report the case of a 66-year-old woman with a progressively enlarging mass in the left parotid region. Initial assessments, including fine needle aspiration biopsy and imaging studies from outside institutions, suggested a diagnosis of squamous cell carcinoma. However, final histopathological analysis revealed that the mass was consistent with a pilomatrixoma. This case highlights the critical importance of meticulous radiological interpretation and the role of fine needle aspiration cytology (FNA) in accurately distinguishing between these 2 entities before initiating treatment.

腮腺区毛瘤基质瘤:一种类似转移性皮肤鳞状细胞癌的良性肿瘤
成人头颈部肿瘤存在广泛的鉴别诊断,特别是当考虑到需要及时诊断和干预的恶性肿瘤时。我们报告的情况下,66岁的妇女与一个逐渐扩大的肿块在左侧腮腺区域。初步评估,包括细针穿刺活检和外部机构的影像学检查,建议诊断为鳞状细胞癌。然而,最终的组织病理学分析显示该肿块与毛基质瘤一致。该病例强调了细致的放射学解释和细针穿刺细胞学(FNA)在开始治疗前准确区分这两种实体的重要性。
