  • Title: Bilateral intra-lymph node Warthin's tumor as a potential diagnostic pitfall mimicking metastatic carcinoma.
    Author: Santos-Sousa AL, Camilo-Júnior DJ, Conrado-Neto S, Bernabé DG, Xavier-Júnior JCC.
    Journal: Diagn Cytopathol; 2024 Mar; 52(3):E59-E62. PubMed ID: 38059407.
    Abstract:
    Warthin's tumor (WT) is a benign and frequent salivary gland tumor primarily affecting the parotid gland. In some cases, this tumor can involve the extra parotid region and affect cervical lymph nodes. Fine-needle aspiration can be the first step in the diagnostic approach to lymphadenopathy; however, specimens from intra-nodal WT can present a potential pitfall, leading to a misdiagnosis of metastasis. Here, we report an unusual case of a patient with bilateral WT in parotid lymph nodes misdiagnosed as metastases. In addition, we highlight the cytopathological aspects of WT to alert cytopathologists about this challenging diagnosis.
