Heterogeneity in gingival fibromatosis

A review of cases indicated that gingival fibromatosis occurs in a variety of genetic entities. High risk for epilepsy and oligophrenia is associated if hypertrichosis is present. Other entities are symmetrical gingival fibromatosis; Zimmermann-Laband syndrome with bone, ear, nose and nail defects and hepatosplenomegaly; Murray syndrome with multiple hyaline dermal tumors; Rutherfurd syndrome with corneal dystrophy; Cowden syndrome with hypertrichosis, oligophrenia and giant fibroadenomatosis of breasts and Cross syndrome of hypopigmentation, oligophrenia and athetosis.
