In 1883, Kobylinski1 described a remarkable deformity of the skin of the neck in a young man suffering from pulmonary tuberculosis. On both sides of the neck there was a pronounced fold of skin running from the mastoid to the acromion. Each fold was prominently visible when the head was turned in the opposite direction, the shoulders being shrugged. In the performance of this action while the patient was recumbent, a cavity was formed which would hold not less than 45 cc. of water. The mobility of the head was not seriously impaired.
