Title: Concerrent follicular adenoma and multiple ectopic parathyroid glands with an atypical parathyroid adenoma
Abstract: Ectopic intrathyroid parathyroid glands may be the cause of primary hyperparathyroidism, parathyroid adenoma or carcinoma. Intrathyroid parathyroid tumors are not common lesions and are difficult to diagnose, both clinically and histologically; especially when the patient has no hyperparathyroid symptoms. A 45-year-old Thai woman was treated as having non-toxic goiter for 20 years. She was diagnosed with papillary carcinoma of the thyroid gland with lung metastases. During investigations of her hemoptysis and right lung atelectasis, incidental bilateral lobe enlargement was detected of her substernal thyroid gland, with multiple hypodense nodules on both lobes. Total thyroidectomy was performed after cytological studies failed to give a definite diagnosis. She did not have hyperparathyroid symptoms and her serum calcium level prior to surgery was normal (8.4mg/dL, normal 8.4-10.2mg/dL). The surgical specimen revealed concurrent follicular adenoma with degenerative changes (left lobe, 5.5 × 7.0cm), multiple ectopic parathyroid (right lobe, 0.5 × 0.7cm) and atypical parathyroid adenoma (right lobe, 2.5 × 3.5cm). The occurrence of ectopic lesions is explainable on an embryologie basis. Non-functioning parathyroid adenoma is uncommon and coexisting thyroid tumors are rare.
