Dermatofibroma ialah keadaan kulit yang biasa ditemui kebanyakannya pada lengan atau kaki. Ia kelihatan sebagai ketulan padat di bawah kulit, selalunya bersaiz kurang daripada 1 sentimeter. Walaupun biasanya tidak menyakitkan, ia mungkin dikaitkan dengan kecederaan ringan yang lalu seperti gigitan serangga atau tusukan duri. Dermatofibroma boleh menjejaskan sesiapa sahaja tetapi lebih kerap berlaku pada wanita berumur 20 hingga 40 tahun. Mereka biasanya jinak, tetapi kadangkala ia boleh kembali selepas penyingkiran. Adalah penting untuk membezakan dermatofibroma daripada tumor kulit yang lebih agresif yang dipanggil 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.

Rawatan pilihan untuk lipomas, dermatofibromas, keratoacanthomas, pyogenic granulomas, and epidermoid cysts ialah pembuangan pembedahan. Cherry angiomas and sebaceous hyperplasia biasanya dirawat dengan terapi laser atau elektrodesikasi. Cryotherapy dan pemotongan cukur adalah pilihan popular untuk acrochordons and seborrheic keratoses. Jika doktor keluarga berasa tidak pasti tentang mendiagnosis atau merawat lesi, atau jika biopsi mengesahkan melanoma, rujukan kepada pakar adalah disyorkan.
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.

Dermatofibroma mungkin terbentuk sebagai tindak balas kepada kecederaan sebelumnya seperti gigitan serangga atau duri. Dermatofibroma dikelaskan sebagai lesi kulit jinak, bermakna ia tidak berbahaya sama sekali, walaupun Dermatofibromas mungkin dikelirukan dengan pelbagai tumor subkutan. Dermatofibroma yang menembusi dalam mungkin sukar untuk dibezakan, malah secara histologi, daripada tumor fibrohistocytic malignan yang jarang berlaku seperti "dermatofibrosarcoma protuberans".
○ Diagnosis dan Rawatan
Kebanyakannya adalah jinak, tetapi lesi besar (>5 mm) mungkin memerlukan biopsi.
