Intranuclear rodlets in an intrathyroid tumor associated with hyperparathyroidism. 1977

R P Sherwin, and C Kaufman, and G R Dermer, and S A Monroe

A tumor excised from the thyroid gland has been shown by electron microscopy to contain distinctive, intranuclear rodlets. This is the first report of such rodlets in a non-neuronal human tumor. While the parathyroid-like hormonal activity, histopathology, and clinical course are consistent with a parathyroid adenoma, the finding of the rodlets raises the question of origin from a special, neuron-related cell of the parathyroid or thyroid. The unusual cellular granularity and the abundant interstitial fibrillae also suggest an unusual cell of origin. Alternatively, a special metabolic activity may account for the rodlets, or they may have been overlooked in prior studies of adenomas.

UI MeSH Term Description Entries
D006961 Hyperparathyroidism A condition of abnormally elevated output of PARATHYROID HORMONE (or PTH) triggering responses that increase blood CALCIUM. It is characterized by HYPERCALCEMIA and BONE RESORPTION, eventually leading to bone diseases. PRIMARY HYPERPARATHYROIDISM is caused by parathyroid HYPERPLASIA or PARATHYROID NEOPLASMS. SECONDARY HYPERPARATHYROIDISM is increased PTH secretion in response to HYPOCALCEMIA, usually caused by chronic KIDNEY DISEASES.

D002467 Cell Nucleus Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed) Cell Nuclei,Nuclei, Cell,Nucleus, Cell
