fibromatosis

 [fi″bro-mah-to´sis]
1. the presence of multiple fibromas.
2. the formation of a fibrous tumorlike nodule arising from the deep fascia, with a tendency to local recurrence.
fibromatosis gingi´vae (gingival fibromatosis) a noninflammatory fibrous hyperplasia of the gingivae and palate, manifested as a dense, smooth, or nodular overgrowth of the tissues. It is usually inherited as an autosomal dominant trait, but some cases are idiopathic and others are produced by drugs.
palmar fibromatosis fibromatosis involving the palmar fascia, and resulting in Dupuytren's contracture.
plantar fibromatosis fibromatosis involving the plantar fascia manifested as single or multiple nodular swellings, sometimes accompanied by pain but usually unassociated with contractures.

fi·bro·ma·to·sis

(fī'brō-mă-tō'sis),
1. A condition characterized by multiple fibromas, with relatively widespread distribution.
2. Abnormal hyperplasia of fibrous tissue.

1. the presence of multiple fibromas.
2. the formation of a fibrous, tumor-like nodule arising from the deep fascia, with a tendency to local recurrence.

aggressive fibromatosis  desmoid tumor, particularly one that is extra-abdominal.
fibromatosis gingi´vae , gingival fibromatosis noninflammatory fibrous hyperplasia of the gingiva manifested as a dense, diffuse, smooth or nodular overgrowth of the gingival tissues.
palmar fibromatosis  fibromatosis of palmar fascia, resulting in Dupuytren's contracture.
plantar fibromatosis  fibromatosis of plantar fascia, with single or multiple nodular swellings, sometimes with pain but usually without contractures.

fibromatosis

[-mətō′sis]
Etymology: L, fibra + Gk, oma, tumor, osis, condition
a gingival enlargement believed to be hereditary or idiopathic, manifested in the secondary dentition. It is characterized by a firm hyperplastic tissue that covers the surfaces of the teeth. Differentiation between this condition and phenytoin hyperplasia is based on a history of phenytoin ingestion. The gums consist of fibrous lesions that demonstrate an infiltrative growth pattern and aggressive clinical behavior. Histologically, it presents as dense hypocellular and hypovascular collagenous tissue which forms interlacing bundles running in all directions. See gingival hyperplasia. Not to be confused with neurofibromatosis.

fibromatosis

Any of a family of benign fibrous-tissue (neoplastic) proliferations with similar microscopic features and aggressiveness intermediate between benign fibrous lesions and low-grade fibrosarcoma, differing from the former in their marked tendency to recur, and from the latter as they do not metastasise.

Types
(1) Superficial—fascial, affecting the palm (Dupuytren’s contracture), penis (Peyronie’s disease) and knuckles.
(2) Deep—aponeurotic and associated with desmoid tumours.

fi·bro·ma·to·sis

(fī-brō'mă-tō'sis)
1. A condition characterized by the occurrence of many fibromas, with a relatively large distribution.
2. Abnormal hyperplasia of fibrous tissue.

fibromatosis

The simultaneous occurrence of a number of tumour-like collections of fibrous tissue that actively spread to cause damage, such as KELOID formation in the skin, nodules and contractures in the palms of the hands and feet, scarring in the COLON and distortion of the penis on erection.

fibromatosis

formation of multiple widespread fibromas

fi·bro·ma·to·sis

1. A condition characterized by multiple fibromas, with relatively widespread distribution.
2. Abnormal hyperplasia of fibrous tissue.

fibromatosis (fī´brōmətō´sis),

n a gingival enlargement believed to be a hereditary condition that is manifested in the permanent dentition and characterized by a firm hyperplastic tissue that covers the teeth. Differentiation between this and diphenylhydantoin (Dilantin) hyperplasia is based on a history of drug ingestion.

In Paris in 1834, Baron Guillaume Dupuytren * (1777-1835) described the basics of anatomy and surgical treatment of palmar fibromatosis, which was later called Dupuytren's contracture after him [11].
Among the differential diagnosis are lipoma, lipoblastoma, fibromatosis, cystic hygroma and pilomatrixoma.
