Dermatofibroma er algengur húðsjúkdómur sem finnst aðallega á handleggjum eða fótleggjum. Það birtist sem fastir hnúðar undir húðinni, oft innan við 1 sentímetrar að stærð. Þó það sé venjulega sársaukalaust, getur það tengst minniháttar meiðslum frá fyrri tíð eins og skordýrabiti eða þyrnastungum. Dermatofibromas geta haft áhrif á alla en eru algengari hjá konum á aldrinum 20 til 40 ára. Þau eru yfirleitt góðkynja en stundum geta þau komið aftur eftir að þau hafa verið fjarlægð. Það er mikilvægt að aðgreina dermatofibromas frá árásargjarnara húðæxli sem kallast 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.

Æskileg meðferð við lipomas, dermatofibromas, keratoacanthomas, pyogenic granulomas, epidermoid cysts er skurðaðgerð. Cherry angiomas, sebaceous hyperplasia eru venjulega meðhöndlaðir með lasermeðferð eða rafskaut. Kryomeðferð og rakaúrskurður eru vinsælir kostir fyrir acrochordons, seborrheic keratoses. Ef heimilislæknir telur sig vera í óvissu um greiningu eða meðhöndlun meinsemdar, eða ef vefjasýni staðfestir sortuæxli, er mælt með því að vísa til sérfræðings.
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.

Dermatofibromas geta myndast sem viðbrögð við fyrri meiðslum eins og skordýrabiti eða þyrnastungum. Dermatofibromas eru flokkuð sem góðkynja húðskemmdir, sem þýðir að þau eru algjörlega skaðlaus, þó að dermatofibromas geti verið ruglað saman við margs konar æxli undir húð. Erfitt getur verið að greina djúpt ígengandi húðvefjaæxli, jafnvel vefjafræðilega, frá sjaldgæfum illkynja vefjafrumuæxlum eins og „dermatofibrosarcoma protuberans“.
○ Greining og meðferð
Flestar eru góðkynja, en stórar sár (>5 mm) gætu þurft vefjasýni.
