Branchial cyst. (Case of Dr. Parmenter.)
Still another type of cystic growth is connected with the anterior jugular vein. It contains sanguineous fluid, and sometimes true venous blood. Connection with the vein may be determined by making pressure. A growth easily emptied and rapidly refilling will be distinctive. It should not be mistaken for an aneurysm, as it does not pulsate. It is known as a sanguineous cyst.

Branchial cyst or hydrocele of neck. Baby six weeks old. (Case of Dr. Parmenter.)
The difficulty of distinguishing between dermoid cyst and dermoid tumor has been mentioned in the chapter on Tumors. The distinction is one of small importance, for no matter what its character such a growth calls for extirpation. A similar dermoid in the course of the thyrolaryngeal duct is represented in [Fig. 498].
