Simultaneous Metastatic Papillary Thyroid Carcinoma and Carcinoid of the Small Intestine in the Cervical Lymph Node Group

Background: Malignancies, primary or metastatic, and infections are the main causative factors that should be included in the differential diagnosis of cervical adenopathy. Summary: We present a 56-year-old woman who was admitted to our department because of a supraclavicular mass. A neck dissection was performed and two different masses were excised. The histopathological examination showed that the larger mass (measuring 5 cm) was a block of lymph nodes with metastatic papillary carcinoma of the thyroid. In the adjacent fibroadipose tissue, two lymph nodes with metastatic carcinoid tumor were found. The smaller mass (measuring 2 cm) was a lymph node with metastatic carcinoid tumor. The patient underwent total thyroidectomy with ipsilateral radical neck dissection. Histopatological examination of the thyroid gland showed a lesion of papillary carcinoma, measuring 0.6 cm. No further lesions of carcinoid were found. Conclusions: To our knowledge, this is the first report of a coexistence of metastatic papillary thyroid carcinoma and intestinal carcinoid tumor in cervical lymph nodes.
