The follicular variant of papillary carcinoma of the thyroid gland is a commonly recognized, well-defined entity. However, primary mucoepidermoid carcinoma of the thyroid is rare, with only 21 cases reported. We describe a 29-year-old woman who presented with a mass in the right lobe of the thyroid. The tumor was classified as the follicular variant of papillary carcinoma of the thyroid with several foci of mucoepidermoid carcinoma. Both components were invading the capsule and had spread to regional lymph nodes. This is the first reported case in which both the papillary and mucoepidermoid carcinomas were present in the primary tumor and in the metastases.
甲状腺乳头状癌的滤泡变体是一种公认的、定义明确的实体。然而，原发性甲状腺黏液表皮样癌很罕见，仅报道过21例。我们描述了一名29岁女性，她因甲状腺右叶肿物就诊。该肿瘤被分类为甲状腺乳头状癌的滤泡变体，伴有几个黏液表皮样癌灶。两种成分均侵犯包膜并已扩散至区域淋巴结。这是首例报道的原发性肿瘤及转移灶中同时存在乳头状癌和黏液表皮样癌的病例。
