Atypical parathyroid adenoma: A case report.

The atypical parathyroid adenoma is a histological diagnosis. It is a parathyroid tumor with atypical histological features different from an adenoma and not similar enough to be considered as a carcinoma. It has an uncertain malignant potential.

Synchronous parathyroid carcinoma and papillary thyroid carcinoma.

The simultaneous occurrence of parathyroid carcinoma and nonmedullary thyroid carcinoma is unusual. We report the case of 60-year-old woman who was found to have concurrent parathyroid carcinoma with severe clinical manifestations of primary hyperparthyroidism in addition to an incidental papillary thyroid carcinoma. Parathyroid hormone level was 569 pg/ml (normal range 10-65), and the serum calcium concentration was 13.

Non-islet-cell tumor hypoglycemia as first manifestation of an advanced hepatocellular carcinoma.

In a nondiabetic patient, fasting hypoglycemia is uncommon and warrants careful assessment. Although rare, NICTH should be considered in patients with recurrent hypoglycemia especially in those with risk factors for HCC.

Langerhans Cell Histiocytosis of the Thyroid Leading to the Diagnosis of a Disseminated Form.

Langerhans cell histiocytosis (LCH) is a rare sporadic proliferative disorder of Langerhans cells. LCH rarely involves the thyroid gland. We report herein a case of a disseminated chronic form of LCH with a diagnosis established by histological examination of the thyroid gland.

[Anicteric cholestasis: a rare hepatic dysfunction caused by hyperthyroidism].

Clinical manifestations and visceral involvements described in patients with thyroid disease are many and varied. However, cases of patients with hepatic manifestations have been rarely reported in the literature. We here report the case of a 50 year old patient diagnosed with Graves' disease without a goiter or ocular manifestations.
