Fibroma

The fibroma (colloquially also pedunculate wart , although it is not medically a wart ) is a benign mesenchymal tumor that arises from the growth of fibrocytes . Real fibromas often appear in the skin of the arms and legs as a rounded protrusion up to 1 cm in size. This must be distinguished from irritable fibroids or fibroepithelial polyps , which predominantly develop on the oral mucosa and are signs of chronic inflammation or a chronic mechanical irritation. Irritant fibroids on the gums are called epulis .
Hard fibroma
The hard fibroma ( Fibroma durum ) is rich in fibers or poor in cells and is also known on the skin as dermatofibroma , nodulus cutaneus ("skin knot ") or fibrinous histiocytoma . There are flowing transitions to the cell-rich histiocytoma , which is also viewed as a reaction to microtraumas such as insect bites and occurs primarily on the legs.
A special form is the keloid , which, with the appropriate predisposition , develops spontaneously as a hyperplastic scar .
Soft fibroma
The soft fibroma ( Fibroma molle ), also known as Fibroma pendulans , "pedunculated fibroma" or "pendulous fibroma", is rich in cells and poor in fibers or consists of loosely meshed fibers. It is quite common and occurs primarily in the neck, eyes, armpit, buttocks, and groin areas.
Other forms and locations
- The fibroma cavernosum or angiofibroma contains numerous, often dilated vessels. It occurs almost exclusively in young men. A frequent localization is the nasopharynx .
- The fibroma cysticum contains central softening or dilated lymph vessels .
- The fibroma myxomatodes obtained by liquefaction of the ground substance of connective tissue is formed.
- The irritable fibroma as a result of chronic inflammation or a chronic mechanical stimulus.
Fibromatosis
If fibromas occur more frequently, one speaks of “ fibromatosis in the narrower sense”. The "fibromatoses in the broader sense" include u. a. the desmoid , a semi-malignant , rapidly growing connective tissue tumor.
therapy
Fibromas are surgically removed and should then be examined in the tissue in order to differentiate them from malignant sarcomas , for example malignant fibrous sarcoma .
