ReferencesIs tumor craicinn coitianta é Dermatofibroma a fhaightear go príomha ar na cosa nó ar na lámha. Dealraíonn sé mar chnó daingean faoi chraiceann, go minic níos lú ná 1 ceintiméadar i méid. Cé go mbíonn sé gan phian de ghnáth, d’fhéadfadh sé a bheith nasctha le mionghortuithe san am a chuaigh thart, ar nós greamanna feithidí nó prionsa. Is féidir le dermatofibromas a bheith i bhfeidhm ar aon duine ach tá siad níos coitianta i measc daoine idir 20 agus 40 bliain d'aois. De ghnáth bíonn siad neamhurchóideach, ach uaireanta féadann siad athfhilltar tar éis a bhaint. Tá sé tábhachtach dermatofibromas a idirdhealú ó siadáin craicinn níos ionsaí ar a dtugtar dermatofibrosarcoma protuberans.
Dermatofibroma is a commonly occurring cutaneous entity usually centered within the skin's dermis. Dermatofibromas are referred to as benign fibrous histiocytomas of the skin, superficial/cutaneous benign fibrous histiocytomas, or common fibrous histiocytoma. These mesenchymal cell lesions of the dermis clinically are firm subcutaneous nodules that occur on the extremities in the vast majority of cases and may or may not be associated with overlying skin changes. They are most commonly asymptomatic and usually relatively small, less than or equal to 1 centimeter in diameter. Often, patients who present with a dermatofibroma relate a history of possibly inciting local trauma at the site, such as from an insect bite or superficial puncture wound from thorns or wood splinters. Dermatofibromas occur in people of all ages, although more commonly during the ages of the 20s to 40s, and develop more frequently in females than males, with as high as a 2:1 female to male predominance according to some reports. They are a benign tumor, although there have been cases of local recurrence, and even more rarely, distant metastases have been reported. When considering the differential diagnosis of these lesions, it is vitally important to distinguish dermatofibromas from dermatofibrosarcoma protuberans, a similar-appearing but more aggressive cutaneous neoplasm.

Is é an chóireáil is fearr le haghaidh lipomas, dermatofibromas, keratoacanthomas, pyogenic granulomas, epidermoid cysts ná baint mháinliachta. Déantar Cherry angiomas, sebaceous hyperplasia a chóireáil go coitianta le teiripe léasair nó leictridhílsiú. Is roghanna coitianta iad críothairipe agus bearradh bearrtha le haghaidh acrochordons, seborrheic keratoses. Má bhraitheann dochtúir teaghlaigh éiginnte faoi dhiagnóiseadh nó cóireáil lesa, nó má dheimhníonn biopsa melanoma, moltar atreorú chuig speisialtóir.
The preferred treatment for lipomas, dermatofibromas, keratoacanthomas, pyogenic granulomas, epidermoid cysts is surgical removal. Cherry angiomas, sebaceous hyperplasia are commonly treated with laser therapy or electrodesiccation. Cryotherapy and shave excision are popular choices for acrochordons, seborrheic keratoses. If a family physician feels uncertain about diagnosing or treating a lesion, or if a biopsy confirms melanoma, referral to a specialist is recommended.

Féadfar dermatofibromas a fhorbairt mar fhreagra ar gortuithe roimhe seo, mar shampla greamanna feithidí nó prionsa dealga. Aicmítear dermatofibromas mar leasa neamhurchóideacha craicinn, rud a chiallaíonn go bhfuil siad go hiomlán neamhdhíobhálach, cé go bhféadfaí Dermatofibromas a mheascadh le héagsúlacht tumóirí subcutáineacha. D’fhéadfadh sé a bheith deacair dermatofibromas dhoimhneach a idirdhealú, fiú go histéineolaíoch, ó thumóirí fibrohistocytic hailí annamh mar “dermatofibrosarcoma protuberans”.
○ Diagnóis agus Cóireáil
Is minic iad neamhurchóideacha, ach d’fhéadfadh leasaí móra (>5 mm) gá le biopsí.
