Dermatofibroma
☆ Yng nghanlyniadau Stiftung Warentest 2022 o’r Almaen, roedd boddhad defnyddwyr â ModelDerm ond ychydig yn is nag ymgynghoriadau telefeddygaeth taledig.
Achos nodweddiadol o Dermatofibroma ― Nodwl caled ar yr aelod. Mae Dermatofibroma yn diwmor anfalaen cymharol gyffredin.

Mae Dermatofibroma yn gyflwr croen cyffredin a geir yn bennaf ar y breichiau neu'r coesau. Mae'n ymddangos fel lympiau cadarn o dan y croen, yn aml yn llai nag 1 centimetr o faint. Er ei fod fel arfer yn ddi-boen, gall fod yn gysylltiedig â mân anafiadau yn y gorffennol fel brathiadau pryfed neu bigau drain. Gall dermatofibromas effeithio ar unrhyw un ond maent yn fwy cyffredin ymhlith merched 20 i 40 oed. Maent fel arfer yn ddiniwed, ond weithiau gallant ddod yn ôl ar ôl tynnu. Mae'n bwysig gwahaniaethu dermatofibromas a thiwmor croen mwy ymosodol o'r enw 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.

Y driniaeth a ffefrir ar gyfer lipomas, dermatofibromas, keratoacanthomas, pyogenic granulomas, epidermoid cysts yw tynnu llawfeddygol. Mae Cherry angiomas, sebaceous hyperplasia yn cael eu trin yn gyffredin â therapi laser neu electrodysodiad. Mae cryotherapi a thorri eillio yn ddewisiadau poblogaidd ar gyfer acrochordons, seborrheic keratoses. Os yw meddyg teulu yn teimlo'n ansicr ynghylch gwneud diagnosis neu drin briw, neu os yw biopsi yn cadarnhau melanoma, argymhellir cyfeirio at arbenigwr.
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.

Gall dermatofibromas gael ei ffurfio fel adwaith i anafiadau blaenorol fel brathiadau gan bryfed neu bigau drain. Mae dermatofibromas yn cael eu dosbarthu fel briwiau croen anfalaen, sy'n golygu eu bod yn gwbl ddiniwed, er y gall dermatofibromas gael eu cymysgu ag amrywiaeth o diwmorau isgroenol. Gall fod yn anodd gwahaniaethu dermatofibromas treiddiol dwfn, hyd yn oed yn histolegol, oddi wrth diwmorau ffibrohistocytig malaen prin fel "dermatofibrosarcoma protuberans".
○ Diagnosis a Thriniaeth
Mae'r rhan fwyaf yn ddiniwed, ond efallai y bydd angen biopsi ar friwiau mawr (>5 mm).
