Considering the extremely high PTH values parathyroid carcinoma was suspected, but the histological examination found an encapsulated, cellular, homogenous lesion, composed of chief cells with some oxyphil cells in a delicate capillary network, with minimal mitotic activity.
Increases in both perfusion and functional activity and targeting of abundant mitochondria-rich oxyphil cells seem to be relevant mechanisms of uptake.
Calculation of average oxyphil scores: A quantitative assessment was made of the number of oxyphil cells by measuring the diameter in microns of each group of oxyphil cells in sections taken through the maximum diameter of each gland and summating the areas thus obtained by the formula [PI] ab, where 'a' & 'b' represent one half of each major & minor axis respectively, as stated by Christie A.

Because of the correlation between the number of oxyphil cells and abnormal parathyroid tissue visualization in sestamibi scintigraphy, it rarely yields positive results for PCs.
Oxyphil parathyroid carcinomas: a clinicopathologic and immunohistochemical study of 10 cases.
Histopathologic examination revealed that parts of the tumor contained a lobulated architecture composed of sheets, cords, and follicles of chief cells, oxyphil cells, and clear cells; these findings were consistent with an adenoma.
