Abstract
Sarcoidosis is a systemic granulomatous disease that primarily affects the lung and lymphatic system of the body. Since Brincker first noted a statistically significant increase of malignant tumors among sarcoidosis patients, there have been several reports on simultaneously developed sarcoidosis and malignancy. A 30-year-old man was admitted to our hospital because of multiple enlarged mediastinal lymph nodes. The patient had been well until approximately 10 days before admission, when he developed a cough. Chest X-ray and computed tomography (CT) of the chest that were performed at the outpatient department revealed multiple enlarged mediastinal lymph nodes. Cervical lymph node biopsy revealed both non-caseating granuloma and metastatic papillary carcinoma, whereas the mediastinal lymph node showed only non-caseating granuloma. The thyroid gland surgical specimen showed papillary carcinoma. We report here on a case of a 30-year-old man who had sarcoidosis and thyroid cancer, and we include a review of the literature.
