What is a Hemosiderotic dermatofibroma?

What is a Hemosiderotic dermatofibroma?

Abstract. A dermatofibroma (DF) is a common, benign tumor composed of fibroblastic and histiocytic cells. DF presents clinically with several different reported variants. One rare variant is hemosiderotic DF (HDF), which is made up of small blood vessels and hemosiderin deposits.

What is aneurysmal dermatofibroma?

Aneurysmal dermatofibroma is a rare mesenchymal tumor arising from fibroblast and histiocytic cells in the dermal layer of the skin. 4. It is one of several variants of the more common and benign dermatofibroma, although it is histologically and morphologically distinct in its features and behavior.

What is Dermatofibrosis?

Dermatofibromas are small, noncancerous (benign) skin growths that can develop anywhere on the body but most often appear on the lower legs, upper arms or upper back. These nodules are common in adults but are rare in children. They can be pink, gray, red or brown in color and may change color over the years.

How common is cellular Dermatofibroma?

How common are cellular dermatofibromas? Dermatofibromas are somewhat common. About 3 in every 100 skin lesions is a dermatofibroma. A skin lesion is a growth, mole or sore on or in your skin.

What is a fibrous histiocytoma?

Fibrous histiocytoma is the most common primary mesenchymal orbital tumor in adults. It may involve ocular structures such as the orbit, lids, conjunctiva, and ocular limbus. Most fibrous histiocytomas are benign, but some are locally aggressive and malignant.

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).

What is a cellular dermatofibroma?

A cellular dermatofibroma is a noncancerous skin growth. It may look like a small, firm bump, similar to a mole. Unlike other dermatofibromas, cellular dermatofibromas often attach to your deepest layer of skin. Because they’re noncancerous, they usually don’t need treatment. Appointments 216.444.5725.

Is dermatofibroma a lesion?

Dermatofibromas are noncancerous lesions, but seek medical evaluation if a lesion begins to increase in size, becomes painful, or if large numbers of dermatofibromas in grouped or linear clusters are seen.

Is cellular dermatofibroma malignant?

Are cellular dermatofibromas malignant? By definition, cellular dermatofibromas aren’t malignant (noncancerous). But they’re more likely than other types of dermatofibromas to spread to other parts of your body (metastasize).

Can dermatofibromas turn cancerous?

A dermatofibroma is an overgrowth of the tissue in the dermis layer of the skin. It is a small, firm bump on the skin. They are harmless and will not turn into skin cancer.

Is Dermatofibroma a tumor?

Cellular dermatofibromas are a type of dermatofibroma (noncancerous tumor). They appear as firm bumps (nodules), often on your legs.

Can a dermatofibroma become cancerous?

However, if a person has a growth that looks like a dermatofibroma but is rapidly growing or changing, they should seek medical advice. This growth may be a sign of a rare type of cancer called dermatofibrosarcoma protuberans.

Is cellular dermatofibroma benign?

Dermatofibroma (fibrous histiocytoma) represents a frequent benign mesenchymal neoplasm of the skin, which rarely may also occur in subcutaneous and deep soft tissues.

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.
