Sarcoidosis is a systemic inflammatory disease characterized by the formation of immune granulomas in multiple organs. The cause of this disease is not yet clear. Papillary thyroid cancer (PTC) is the most common malignant endocrine tumor and is often associated with cervical lymph node metastasis. Assessment of risk factors associated with a poor prognosis is crucial in PTC. The coexistence of sarcoidosis and thyroid cancer is rarely reported in the literature. We describe a case of a 54-year-old female diagnosed with PTC and asymptomatic cervical and thoracic hilar lymphadenopathy due to concurrent sarcoidosis. This case will remind clinicians to be aware of the multiple potential causes of lymphadenopathy and realize the importance of the differences in the features of neck lymphadenopathy in patients with suspected head and neck cancer. Overall, careful workup and pretreatment screening enabled us to provide the patient with the most suitable treatment modality and avoid total thyroidectomy.
