Detailed explanation-1: -The parathyroid glands of young adults consist primarily of chief cells. However, with age or after excessive functional stress, another cell type appears in the parathyroid gland, the oxyphil cell (1, 2). Histologically, oxyphil cells are larger than chief cells (12–20 vs.
Detailed explanation-2: -Large cells with small irregular nuclei and dense acidophilic granules due to the presence of abundant MITOCHONDRIA. Oxyphil cells, also known as oncocytes, are found in oncocytomas of the kidney, salivary glands, and endocrine glands. In the thyroid gland, oxyphil cells are known as Hurthle cells and Askenazy cells.
Detailed explanation-3: -Oxyphil cells of the thyroid are cytochemically akin to C cells but arise from follicular cells. They occur in the thyroid and other protein-producing organs, but are themselves inefficient producers of proteins and glycoproteins.
