Gingival fibromatosis represents the fibrous hyperplasia of the gingival tissue. Clinical examination reveals enlargement of buccal and palatal gingival tissue. Many forms of gingival fibromatosis are of unknown etiology and termed as idiopathic gingival fibromatosis.

The role of lipoid proteinosis in gingival hypertrophy.

Hyalinosis cutis et mucosae (lipoid proteinosis, Urbach-Wiethe disease) is a rare syndrome with autosomal recessive inheritance. The disease is characterized by diffuse deposition of a hyalinelike substance in the dermis, submucosal connective tissue, and various internal organs.
