Abstract PDF: BACKGROUND
Chronic kidney disease is considered a risk factor for thyroid nodules as well as thyroid dysfunction such as hypothyroidism. Among patients on hemodialysis, we assessed the size of thyroid nodule and goiter at baseline and 1 year later with ultrasonography. METHODS: We prospectively selected 47 patients with hemodialysis at January 2012 and reviewed their medical records. We checked goiter and thyroid nodules at January 2012 and December 2012. RESULTS: In the hemodialysis patients (n=47), 24 patients (51.1%) had thyroid nodules and 33 patients (70.2%) had goiter at baseline. Parathyroid hormone (PTH) was higher in patients with thyroid nodules (204.4±102.9 vs. 129.9±93.6 pg/mL, p=0.01). Thyroid ultrasonography was conducted in 29 patients after 1 year. The thickness of the thyroid isthmus increased (2.8±1.6 vs. 3.2±1.9 mm, p=0.003), but the number of nodules did not change (1.2±1.9 vs. 1.4±2.0, p=0.109). PTH was associated with the enlargement of thyroid nodules significantly through logistic regression analysis. CONCLUSION: Thyroid goiter and nodules in hemodialysis patients were more prevalent than in the general population. PTH influenced the production of thyroid nodules in hemodialysis patients. Regular examination with thyroid ultrasonography and thyroid function test should be considered in hemodialysis patients.

The occurrence of a mixed tumor containing papillary thyroid carcinoma (PTC) and primary squamous-cell carcinoma (SCC) is rare because there is no squamous epithelium in the thyroid gland. Reported herein is a 30-year-old female with mixed PTC and primary SCC of the thyroid presented as thyroid incidentaloma. Fine-needle aspiration biopsy of the thyroid nodule revealed the presence of malignant thyroid cells. The histopathological examination following total thyroidectomy yielded two mixed, morphologically distinct histotypes that included PTC and SCC. After total thyroidectomy, the patient underwent radioactive iodine therapy. No recurrence or metastasis occurred during the 20-month follow-up period after the operation.
