What is Dermatofibroma?
Dermatofibroma, also referred as benign fibrous histiocytoma, is a relatively common noncancerous cutaneous nodule. Males are less affected by dermatofibroma than females, with a female-to-male ratio of 4:1. The exact etiology for the development its development is still undetermined. This condition appears more likely to be a neoplastic mechanism for the reason that the nature of the lesion is persistent.
Characteristically, the disease presents as a solitary nodule about ½ to 1 centimeter in diameter. In rare cases, an individual may develop more than a few lesions. The involved skin surface is slightly pigmented and can vary from tan to black. If palpated, the nodule feels like a small pebble, and is freely movable when manipulated. Most common body areas involved are the extremities predominantly on the lower leg. A dimple sign is displayed where the middle section wrinkles as the nodule is compressed on the edges.
Self care guidelines are not necessary. Dermatofibromas are best ignored. Still, it can be removed surgically via excision, but since they are deep-seated, this usually leaves a scar. In addition, due to high incidence of recurrence, topical corticosteroids and injectables are necessary post operation. If the lesion is protruding, the patient may undergo cryosurgery for lesional size reduction. If the nodule starts to increase in dimension and becomes painful, it is important to seek a physician for a medical evaluation.
