Abstract

The embryology and physiology of the parathyroid glands have been studied extensively by various observers, 'but practically nothing is known so far concerning the pathologic changes that may occur in these structures. A beginning is made by Benjamins,1 however. He finds that in man these glands generally occur in pairs, one on each side, and that they develop probably from the fourth branchial clefts. Kohn and others observed a duct-like passage in connection with the parathyroids; Benjamins regards this duct as analogous to the thyroglossal duct, and he proposes for it the name ductus parathyroideus. It would not be surprising were this duct to become the seat of cystic dilatation in cases of incomplete obliteration, thus forming an additional variety of cyst in the neck. Benjamins noted that the usual regressive changes occur in the parathyroid glands as in other organs; in a case of general miliary tuberculosis tubercles
