A dermatofibroma is a common benign fibrous nodule usually found on the skin of the lower legs. A dermatofibroma is also called a cutaneous fibrous histiocytoma.Dermatofibroma 101 (Benign Fibrous Histiocytoma)...Explained by a Dermatopathologist
Do dermatofibroma have blood vessels?
Blood vessels were observed in 44% of dermatofibromas in the study by Agero et al10 when polarized contact dermoscopy was used. These authors also found a central pink hue in 10% of cases and a peripheral diffuse pinkish or reddish area in 28% of cases using polarized contact dermoscopy (Table 3).Can you squeeze a dermatofibroma?
If you pinch a dermatofibroma, it creates a dimple because it is attached to the underlying subcutaneous tissue. 1 On the other hand, if you pinch a mole, it projects up away from the skin. Moles appear when skin cells grow in clusters.Can dermatofibroma be soft?
Dermatofibroma, also known as fibrous histiocytoma, is one of the most common cutaneous soft-tissue lesions, accounting for approximately 3% of skin lesion specimens received by dermatopathology laboratories.Are dermatofibromas scaly?
Dermatofibromas are usually single nodules that develop on an extremity, most commonly the lower legs. They are freely moving, firm-to-hard nodules of 0.5-1.0 cm diameter. The skin's surface is generally smooth, occasionally scaly. The overlying skin may be tethered, causing it to dimple when pinched.Why do I feel a ball in my skin?

They are well circumscribed, solitary or multiple, usually hyperpigmented dermal nodules, typically less than 1 cm in diameter. They may be slightly protuberant, but are most often flat, and are generally located on the extremities.Is dermatofibroma itchy?
Dermatofibromas are usually asymptomatic, but itching and pain often are noted. They are the most common of all painful skin tumors.Do all dermatofibromas dimple?
Roughly 80 percent of all dermatofibromas will involute or withdraw below the surface of the skin when one applies lateral squeeze compression, creating a dimple in the skin. Although this “dimple sign” is not exclusive to dermatofibromas, it is still a very useful clinical sign.Why do I have a small ball under my skin?
Epidermoid cystAn epidermoid cysts are small, round lumps under your skin. They usually develop when shed skin cells move into your skin instead of falling off. Epidermoid cysts can also form when hair follicles become irritated or damaged, due to a buildup of keratin.
What feels like a BB under my skin?
Dermatofibromas contain scar tissue, so they will feel hard. Some people describe them as feeling like a BB gun pellet stuck below the skin. Usually asymptomatic, they may cause some itching, pain, or tenderness. These typically don't need to be removed, but they can be surgically removed if they become painful.What does a tumor feel like under the skin?
They may feel like small peas beneath the surface of the skin. They usually feel smooth and may roll under the skin when pressure is applied to them.Can dermatofibroma be raised?
Most common symptomsDermatofibromas are raised, firm bumps that are usually less than 1 cm in diameter, but on occasion can be larger.
What is an atypical dermatofibroma?
Atypical dermatofibroma is also known as dermatofibroma with monster cells or pseudosarcomatous dermatofibroma. There are focal areas within a common dermatofibroma consisting of large polymorphous cells with large nucleoli ('monster cells') (figures 9, 10).How can you tell if a lump is cancerous?
Bumps that are cancerous are typically large, hard, painless to the touch and appear spontaneously. The mass will grow in size steadily over the weeks and months. Cancerous lumps that can be felt from the outside of your body can appear in the breast, testicle, or neck, but also in the arms and legs.Is dermatofibroma malignant?
The present case demonstrates that although dermatofibromas are essentially benign, they may present with atypical features including large size, ulceration, and muscle invasion, clinically mimicking malignant tumors.Do dermatofibromas appear suddenly?
There are specific situations where dermatofibromas can be associated with underlying health issues. Typically, multiple dermatofibroma lesions that arise suddenly are seen in these situations. If you have multiple skin lesions that have come on suddenly, you should discuss this with your physician.What is cellular dermatofibroma?
Cellular dermatofibroma, also known as cellular fibrous histiocytoma, is a subtype of the cutaneous soft-tissue lesion, dermatofibroma. Dermatofibroma is a common lesion, and it accounts for approximately 3% of the skin lesion specimens received by dermatopathology laboratories.What is atrophic dermatofibroma?
The atrophic dermatofibroma is a variant of dermatofibroma, clinically characterized by an atrophic and depressed lesion. Histopathology reveals dermis thickness reduction by 50% in relation to the adjacent dermis.What are the pea sized lumps under my skin?
Every person has hundreds of lymph nodes throughout the body. They are movable lumps approximately the size of a pea most typically founds in the armpits, collarbone, groin, and neck.
