Zimmermann-Laband syndrome is a rare disorder characterized by gingival fibromatosis, abnormalities of the nose and/or ears, absence and/or hyperplasia of the nails or terminal phalanges of the hands and feet, hyperextensibility of joints, hepatosplenomegaly, mild hirsutism and mental retardation. The syndromic characteristics of Zimmermann-Laband syndrome are highly variable and complicated. This paper described a patient with Zimmermann-Laband syndrome with new manifestations and discusses the possible underlying genetic mechanisms.
