Dermatofibroma, also called a cutaneous fibrous histiocytoma, is a common benign fibrous growth of the skin. They are composed of a mixture of fibroblastic and histiocytic cells, collagen, and blood vessels. They are firm and often feel like a stone under the skin, most common on the arms, lower legs, and upper back. Dermatofibromas are seen in adults and are rare in children.<\/p>

Dermatofibroma is usually solitary. However, multiple dermatofibromas are can develop in people with weakened immune system. Also, they tend to grow slowly. They occur more frequently in women than in men, however, some histologic variants are more common in males.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
