Representative histological features and reticular fibre staining of atypical parathyroid tumour
A, the presence of coagulation necrosis (arrow) and fibre bands (arrowhead) supports the diagnosis of atypical parathyroid tumours (haematoxylin eosin, 40Ć). B, the anastomotic reticular fibre structure can be seen, the network structure varies in size, but no areas are destroyed (reticular fibre staining, 40Ć). C, the presence of fibre bands and obvious flake supports the diagnosis of atypical parathyroid tumours (haematoxylin eosin, 40Ć). D, a traversable field line can be seen, indicating the destruction of reticular fibre structure (reticular fibre staining, 40Ć)
