[A patient with hypoaesthesia of the mandible]. / Een patiënt met hypesthesie in de mandibula.

In a patient with hypoaesthesia of the central region of the mandible, no oral cause could be found which could explain his complaint. Further examination by a neurologist and a specialist in internal medicine revealed the numb chin syndrome. The syndrome was caused by meningeal localisation of a high-grade B-cell lymphoma stade IV. After intensive chemotherapy and radiotherapy of the skull, the complaints disappeared.
