Fibromasarebenign tumorsthat are composed of fibrous orconnective tissue.[1]They can grow in all organs, arising frommesenchymetissue. The term "fibroblastic"or" fibromatous "is used to describe tumors of thefibrous connective tissue.When the termfibromais used without modifier, it is usually consideredbenign,with the termfibrosarcomareserved formalignanttumors.

Types
editHard fibroma
editThe hard fibroma (fibroma durum) consists of many fibres and few cells, e.g. in skin it is calleddermatofibroma(fibroma simplex or nodulus cutaneous).[2]A special form is thekeloid,which derives from hyperplastic growth ofscars.
Soft fibroma
editThe soft fibroma (fibroma molle) or fibroma with a shaft (acrochordon,skin tag, fibroma pendulans) consist of many loosely connected cells and less fibroid tissue.[3]It mostly appears at the neck, armpits or groin. The photo shows a soft fibroma of the eyelid.
Other types of fibroma
editThe fibroma cavernosum orangiofibroma,consists of many often dilated vessels, it is a vasoactive tumor occurring almost exclusively in adolescent males.
The cystic fibroma (fibroma cysticum) has central softening or dilatedlymphatic vessels.
The myxofibroma (fibroma myxomatodes) is produced by liquefaction of the underlyingsoft tissue.
The cemento-ossifying fibroma is hard and fibrous, most frequently seen in thejawormouth,sometimes in connection with afractureor another type ofinjury.
Other fibromas:chondromyxoid fibroma,desmoplasmic fibroma,nonossifying fibroma,ossifying fibroma,nuchal fibroma,collagenous fibroma,fibroma of tendon sheath,perifollicular fibroma, pleomorphic fibroma,uterine fibroma,Gardner fibroma,etc.
Theneurofibromais a benign nerve-sheath tumor in the peripheral nervous system.
Ovarian fibroma
editIt appears in thesex cord-stromal tumourgroup ofovarian neoplasms.Ovary fibromas are most frequent duringmiddle age,and rare inchildren. Upon grosspathologicalinspection, ovary fibromas are firm and white or tan. Variants withedemaare especially likely to be associated withMeigs' syndrome. Onmicroscopicexamination, there are intersecting bundles of spindle cells producingcollagen.
There may bethecomatousareas (fibrothecoma). The presence of an ovarian fibroma can causeovarian torsionin some cases.
Treatment
editBenign fibromas may, but need not, be removed. Removal is usually a brief outpatient procedure or using cryotherapy in which the lesion is deep frozen (-196 degrees Celsius using liquid nitrogen) and thawed for two or more cycles, with full recovery within 3 to 4 weeks. The cryotherapy treatment needs no anesthetics and is painless. Another simple treatment is snip removal after injecting local anesthetic.

The fibroma is a benign tumor, frequently found in fascia and subcutaneous tissue. As is true of most benign tumors, it is composed of cells of fairly normal appearance — in this case, fibroblasts.
