In this study, we found that unrecognized adult celiac disease in Central Anatolia affects approximately 1% of the population, and the major constellation of symptoms are nonspecific gastrointestinal related. Serologic data are not adequate for a definite diagnosis, but the anti-tissue transglutaminase IgA test has high diagnostic value and may be used as screening tool. Confirmation with intestinal biopsy is required for a definite diagnosis.

A 33-year-old man was admitted with a swelling in the right lobe of the thyroid gland of 1 years duration. Laboratory investigations and thyroid function tests were normal. Thyroid scanning showed a cold nodule in the lower pole of the right thyroid lobe. Thyroid ultrasonography showed multiple cystic nodules in the thyroid gland. To make a differential diagnosis of the thyroid nodule, fine-needle aspiration biopsy (FNAB) was performed and hydatic cyst of the thyroid gland was diagnosed. Subtotal thyroidectomy was carried out and histopathologic examination confirmed the diagnosis. During aspiration biopsy, the patient did not present a clinical picture of anaphylactic reaction. To our knowledge, this is the first case of thyroid hydatic cyst diagnosed by FNAB reported in the literature.

We report two cases of thyroidal plasma cell granuloma. Both patients underwent surgical resection after presenting with painless neck swelling. Histopathologic examination of the specimens revealed plasmacytes infiltrating the thyroid parenchyma and immunohistochemical studies showed the polyclonal nature of the plasma cells. Plasma cell granuloma is a benign lesion and its appearance in the thyroid gland is extremely rare. Eleven prior cases with thyroid localization have been reported to date in the English literature. Nine of the plasma cell granuloma cases occurred in women, four in men (including the present cases). The clinicopathologic features and diagnostic difficulties of this rare entity are described, and its relation to inflammatory pseudotumor of other sites is discussed with a review of the literature.
