Representative histological features and reticular fibre staining of parathyroid carcinoma
A, the tumour invaded the surrounding striated muscle tissue (arrow), and was diagnosed as a parathyroid carcinoma (haematoxylin eosin, 40Ć). B, a traversable field line can be seen, indicating the destruction of reticular fibre structure (reticular fibre staining, 40Ć). A and C show different regions of the same case (haematoxylin eosin, 40Ć). D, The reticular fibre structure was damaged in some, but not in other regions (reticular fibre staining, 40Ć)
