This paper examines the clinical differentiation of pigmented lesions in the oral mucosa, which poses significant diagnostic challenges across dental and medical disciplines due to their spectrum from benign to potentially malignant conditions. Through a literature review and analysis of clinical cases, this study clarifies current diagnostic methodologies, with an emphasis on differential diagnosis, to provide a practical guide for clinicians. The classification of pigmented lesions, such as endogenous, focal melanocytic, and multifocal pigmentation, based on clinical and histological features, highlights the necessity for a structured and informed approach. A retrospective examination of cases from our oral medicine and pathology clinic, coupled with analysis of photographic and histological records, aids in classifying these lesions. This fosters a better understanding and promotes informed discussions among clinicians, ultimately aiming to enhance early and precise diagnosis, thus improving patient management and outcomes.
本文探讨口腔黏膜色素性病变的临床鉴别诊断。此类病变因其涵盖从良性到潜在恶性的多种类型，在口腔医学及临床医学领域均构成显著的诊断挑战。通过文献综述与临床病例分析，本研究阐明了当前的诊断方法学，并着重于鉴别诊断，旨在为临床医师提供实用指导。基于临床与组织学特征，将色素性病变分为内源性、局灶性黑色素细胞性及多灶性色素沉着等类别，突显了采用系统化、循证化诊断路径的必要性。通过对本院口腔医学与病理科病例的回顾性研究，结合影像学及组织病理学记录分析，有助于对此类病变进行分类。这不仅能深化临床认知，更能促进医师间的有效交流，最终目标在于提升早期精准诊断水平，从而优化患者管理与临床预后。
