......Hemangioma - benign tumor formed by a collection of excess blood vessels in an area usually forming a ball but sometimes a flatter mat. Since blood vessel cells are usually transparent and thin smooth muscle cells, hemangiomas are usually the color of blood that runs through them. If the blood has a lot of oxygen, or is more arterial, the color is usually bright red. If the color is dark the blood is usually low in oxygen or venous or possibly stagnated. Common types of hemangiomas may look like strawberries or red purple mats in children's birthmarks. Other may look like miniature red cherries on adults, are inherited, and range in size from pinheads to small peas (cherry or senile hemangiomas).

......Sebaceous Hyperplasia- Benign hair oil-gland overgrowth. These growths are genetically preprogrammed and usually range in size from a pinhead to the size of a pencil eraser. "Seb hypes," as they are sometimes called, usually look like a tiny, yellow donut just above the face's skin surface. A tiny blood vessel may be present on the seb hype. They rarely go away and usually continue to grow and multiply throughout time. Sometimes they may cause significant cosmetic deformity. They can be treated best with electrosurgery, but some lasers have shown some promise.

......Seborrheic Keratosis - A greasy, oily wart. They are benign but occasionally a squamous-cell cancer has been reported to develop within a seborrheic keratosis. Therefore, careful, close examination is necessary to make sure that all is well. Seborrheic keratosis may arise from lentigos (age freckles) or may start on their own, growing usually as a greasy, stuck-on brown, tan or black wart-like growth. If examined very closely under a magnifying glass, miniature white or light horn pearls (tiny, white beads of keratin that can fit on the tip of a pen) maybe noticed within the seborrheic keratosis. Occasionally, seborrheic keratoses will develop a malignancy within, but that is an extremely rare occasion. Because seborrheic keratoses are so common, there is also a possibility that it/they may collide just by chance with a skin cancer growing nearby. Many times patients confuse seborrheic keratosis with melanoma and go to a doctor for examination. A thorough examination by an experienced doctor is usually a reliable way to tell the difference. Unfortunately, there is a type of melanoma known as verrucous melanoma that can mimic seborrheic keratosis. Fortunately, however, this is an extremely rare event.
