There was no gingival hyperplasia or flexion contracture deformities of the limbs. The proband also showed deformity of the face and skull, stunted growth, osteolysis of terminal phalanges, multiple large subcutaneous fibromatoeis, some calcified, dysseborrheic, sclerodermiform and atrophic changes of the skin, recurrent suppurative infections of the skin, eyes, nose and ears, and gingival fibromatosis.
