Glandula parathyroidea (SFLT)
Glandula parathyroidea – overview (HE stain)[edit | edit source]
Description: C – capsula (fibrous sheath) sends to the gland parenchyma a septum (S) with vessels (K),
vessels/capillaries are also in the parenchyma (fenestrated endothelium), the gland parenchyma has two
types of conspicuously small epithelial cells: chief cells (H) predominate and oxyphil cells (O),
with age, parenchyma cells are replaced by fat cells (T).
Glandula parathyroidea – parenchyma (HE stain)[edit | edit source]
Description: H – main cells, O – oxyphil cells, T – fat cells (they replace secretory cells with age),
between the main and oxyphil cells there are also various cells of the transitional type, which testify to the theory,
that chief and oxyphil cells are two different variants of the same cell type.

Description: H – main cells, O – oxyphil cells, T – fat cells, K - capillaries.
Glandula parathyroidea – parenchyma (HE stain)[edit | edit source]
Description: H – main cells, T – fat cells.
Glandula parathyroidea – main cells detail (HE stain)[edit | edit source]
Description: Main cells are small polygonal epithelial cells with vesicular nuclei. Colors
pale, slightly acidophilic.
Glandula parathyroidea – oxyphil cells detail (HE stain)[edit | edit source]
Description: Oxyphilic cells are also polygonal, but larger than the main cells. Their cores are
smaller and dark in color. Their cytoplasm is strongly acidophilic.
