Das Syndrom von Zimmermann-Laband

: We report on two patients who exhibit the typical features of the rare Zimmermann-Laband syndrome such as gingival fibromatosis, swelling of perioral tissues, nail hypo/aplasia, and abnormalities of terminal phalanges. The older patient suffers from epileptic seizures and shows osseous mandibular hypertrophy, two maxillary mesiodentes and lumbar spondylodysplasia. In the 2nd patient, a 3 year old male, the characteristic morphological features are already present.
