Dermatofibroma
☆ Ann an toraidhean 2022 Stiftung Warentest às a’ Ghearmailt, cha robh sàsachd luchd-cleachdaidh le ModelDerm ach beagan nas ìsle na le co-chomhairlean telemedicine pàighte.
Cùis àbhaisteach de Dermatofibroma ― Nodule cruaidh air a’ bhall. Tha Dermatofibroma na thumar neo-àbhaisteach gu math cumanta.

Tha Dermatofibroma na staid craiceann cumanta a lorgar sa mhòr-chuid air na gàirdeanan no na casan. Tha e a 'nochdadh mar chromagan daingeann fon chraiceann, gu tric nas lugha na 1 ceudameatair ann am meud. Ged a tha e mar as trice gun phian, dh’ fhaodadh gum bi e ceangailte ri leòntan beaga san àm a dh’ fhalbh leithid bìdean bhiastagan no prìneachan droigheann. Faodaidh dermatofibromas buaidh a thoirt air duine sam bith ach tha iad nas cumanta ann am boireannaich aois 20 gu 40. Mar as trice tha iad mì-laghail, ach uaireannan faodaidh iad tilleadh às deidh an toirt air falbh. Tha e cudromach eadar-dhealachadh a dhèanamh air dermatofibromas bho tumhair craiceann nas ionnsaigheach ris an canar 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 e an làimhseachadh as fheàrr le lipomas, dermatofibromas, keratoacanthomas, pyogenic granulomas, epidermoid cysts toirt air falbh lannsaireachd. Mar as trice bidh Cherry angiomas, sebaceous hyperplasia air an làimhseachadh le laser therapy no electrodesiccation. Tha cryotherapy agus sgoltadh bearraidh nan roghainnean mòr-chòrdte airson acrochordons, seborrheic keratoses. Ma tha lighiche teaghlaich a 'faireachdainn mì-chinnteach mu bhith a' breithneachadh no a 'làimhseachadh lot, no ma tha biopsy a' dearbhadh melanoma, thathar a 'moladh fios a chuir gu eòlaiche.
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.

Dh’ fhaodadh dermatofibromas a bhith air an cruthachadh mar fhreagairt do leòntan a bh’ ann roimhe leithid bìdean bhiastagan no prìneachan droigheann. Tha dermatofibromas air an seòrsachadh mar leòintean craiceann mì-laghail, a’ ciallachadh gu bheil iad gu tur gun chron, ged a dh’ fhaodadh Dermatofibromas a bhith air am measgachadh le measgachadh de tumors subcutaneous. Is dòcha gum bi e duilich dermatofibromas domhainn domhainn a bhith eadar-dhealaichte, eadhon gu h-eachdraidheil, bho tumors fibrohistocytic malignant tearc leithid “dermatofibrosarcoma protuberans”.
○ Diagnosis agus Làimhseachadh
Tha a’ mhòr-chuid dhiubh mì-laghail, ach dh’ fhaodadh gum bi feum air biopsy air lotan mòra (> 5 mm).
