A cyst is a benign lesion that presents itself as a round flesh colored nodule under the skin. An epidermal cyst usually occurs in adulthood and can occur anywhere on the body. The contents of an epidermal cyst is keratin, which is the white soft malodorous material. A central pore or punctum may be present. As these cysts are benign no treatment is required. However an epidermal cyst may become inflamed which then causes the area to become red, tender and painful. When cysts become inflamed the treatment of choice is drainage. During the procedure a small incision is made in the cyst and the contents of the cyst is drained. Because this procedure does not remove the cyst in its entirety the cyst may refill and return. To remove a cyst fully surgical excision is required where the cyst is cut out and stitches are placed.
