title: Occurrence of calcitonin cells and cysts in the parathyroid of the house shrew, Suncus murinus.
abstract: The present report deals with the occurrence of calcitonin cells (C cells) and cysts in the parathyroid IV of Suncus murinus. Histological preparations of the thyro-parathyroid complex reveal that (i) the parathyroid IV exhibits C cells either solitarily or in small groups (compact or follicular arrangement); (ii) the parathyroid IV also exhibits cysts (similar to those of the thyroid), the lining of these may contain either few C cells or it may be a continuous lining of C cells; (iii) the lumina of these cysts are filled with debris and desquamated cells with pycnotic nuclei, and (iv) sometimes few C cells are encountered hanging from the epithelial lining inside the lumen of the cyst.
