Primary hyperparathyroidism is a frequent endocrine disorder but intrathyroidal parathyroid adenoma is extremely rare. Combining cervical ultrasound and MIBI scintigraphy allows localizing most parathyroid adenomas. Because intrathyroidal parathyroid adenomas mimic thyroid nodules the diagnosis can be challenging, requiring eventually the realization of a fine-needle cyto-puncture. We report here a case of an intrathyroidal parathyroid adenoma diagnosed via a combination of ce...

Oncocytic adrenocortical neoplasm (OAN) represents a rare variant of adrenocortical carcinoma (ACC) with less than 150 cases reported in the literature. OANs account for 1.8% of adrenal masses, predominantly in adults and usually presenting as large tumors featuring hormonal secretion in 20% of cases. Accurate histological characterization of OANs is crucial as this subtype is believed to be more indolent in clinical behavior. There are 3 categories of OANs: pure oncocytic, mi...
