Warthin tumor is a benign salivary gland tumor comprising ductal epithelium and lymphoid stroma. To date, reports about the malignant transformations of intraepithelial and lymphoid components in Warthin tumor are extremely rare; lymphoid malignant transformation into B-cell lymphoma is particularly rare in combination with T-cell lymphoma. The case of Warthin tumor complicated with T-lymphoblastic lymphoma is reported to emphasize the importance of a careful light microscopic evaluation of lymphoid tissue in Warthin tumor for identifying occult lymphoma presence, reducing misdiagnosis and missed diagnosis, and determining a timely treatment.
Warthin瘤是一种良性唾液腺肿瘤，由导管上皮和淋巴样间质组成，迄今为止，有关Warthin瘤内淋巴成分恶变的报道罕见，且多恶变为B细胞淋巴瘤，合并T细胞淋巴瘤更尤为少见。本文报道1例Warthin瘤合并T淋巴母细胞淋巴瘤，旨在强调要对Warthin瘤内的淋巴组织进行仔细的光学显微镜评估，以识别隐匿性淋巴瘤的存在，减少误诊及漏诊并及时治疗。.
