Congenital anomalies of the spleen range from splenic lobulation, to accessory spleen to polysplenia. Though most of these anatomical variants have no clinical significance, an accessory spleen may simulate a tumor in the adrenal gland, pancreas, stomach or intestine. Alternatively, a missed accessory spleen may be the site of the ...

The parathyroid glands, which usually are situated behind the thyroid gland, secrete parathyroid hormone, or PTH, which helps maintain calcium homeostasis. Primary hyperparathyroidism results from excess parathyroid hormone secretion. In secondary hyperparathyroidism, the normal PTH effect on bone calcium release is lost. Serum PTH rises, causing generalized hyperplasia. In tertiary ...

Parathyroid lesions, which may occur within the thyroid, may clinically simulate thyroid nodules. Fine-needle aspiration (FNA) of these presumably "thyroid nodules" can lead to misinterpretation of cytomorphological findings because of similarities in cytological features of neoplastic and nonneoplastic parathyroid and thyroid lesions. This might be true especially for oncocytic parathyroid ...
