Типичен случай на Дерматофиброма (Dermatofibroma) – твърд възел на крайника. Дерматофиброма (Dermatofibroma) е сравнително често срещан доброкачествен тумор.

ReferencesDermatofibroma е често срещано кожно заболяване, предимно по ръцете или краката. Той се проявява като твърди бучки под кожата, обикновено с размер под 1 см. Въпреки че обикновено е безболезнено, може да бъде свързано с предишни леки травми, като ухапвания от насекоми или наранявания от шипове. Дерматофибромите могат да засегнат всеки, но са по-чести при жени на възраст от 20 до 40 года. Те са доброкачествени, въпреки че понякога могат да се появят отново след отстраняване. Важно е да се разграничат дерматофибромите от по-агресивен кожен тумор – 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.

Предпочитаното лечение за lipomas, dermatofibromas, keratoacanthomas, pyogenic granulomas и epidermoid cysts е хирургично отстраняване. Cherry angiomas и sebaceous hyperplasia обикновено се лекуват с лазерна терапия или електродесикация. Криотерапията и ексцизията при бръснене са популярни избори за acrochordons и seborrheic keratoses. Ако семейният лекар се чувства несигурен относно диагностиката или лечението на лезия, или ако биопсия потвърди меланома, се препоръчва насочване към специалист.
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.

Дерматофибромите могат да се образуват като реакция на предишни наранявания – ухапвания от насекоми или увреждане от шипове. Те се класифицират като доброкачествени кожни лезии, което означава, че са безвредни, въпреки че могат да бъдат объркани с различни подкожни тумори. Дълбоко проникващите дерматофиброми понякога са трудни за разграничаване, дори хистологично, от редки злокачествени фиброхистоцитни тумори като „dermatofibrosarcoma protuberans“.
○ Диагностика и лечение
Повечето са доброкачествени, но големи лезии (>5 mm) могат да изискват биопсия.
