Abstract:

Mucoepidermoid carcinoma (MEC) typically originates from major salivary glands but may also arise primarily from minor salivary glands in the palate. It can show diverse clinical symptoms, such as masses, pain, or ulcers. However, cases presenting primarily with mucosal erythema are relatively rare. This article reports a case of palatal MEC that presented erythema as the main clinical feature, and discusses its clinical characteristics, diagnosis, and treatment.

Key words: mucoepidermoid carcinoma, palate, mucosal erythema, diagnosis

摘要：

黏液表皮样癌（mucoepidermoid carcinoma，MEC）通常起源于大唾液腺，但亦可原发于腭部小唾液腺。其临床表现多样，常见症状包括肿块、疼痛或溃疡，但以黏膜红斑为主要表现者较为罕见。本文报道1例以红斑为主要表现的腭部MEC病例，并对其临床特点、诊断和治疗进行探讨。
