Melanoma: Melanoma is a type of cancer that begins in the skin. It is completely curable when detected early, but can be fatal if allowed to progress and spread. Cancer is a condition where one type of cell grows without limit in a disorganized fashion, disrupting and replacing normal tissues and their functions, much like weeds overgrowing a garden. Melanoma is a cancer of the pigment producing cells in the skin, known as melanocytes. Normal melanocytes reside in the outer layer of the skin and produce the brown pigment melanin, which is responsible for the color of our skin. Melanoma is when melanocytes become cancerous, grow, and invade other tissues.

Melasma: A skin condition presenting as brown patches on the face of adults. The most common sites of involvement are the cheeks, bridge of nose, forehead, and upper lip. Melasma occurs mostly in women. Only 10% of those affected are men. Dark-skinned races, particularly Hispanics, Asians, Indians, people from the Middle East, and Northern Africa, tend to have melasma more than others.

Mohs surgery: In certain situations, your dermatologist may refer you for a specialized technique called Mohs micrographically controlled surgery. In this method, performed by specially trained dermatologic surgeons, the skin cancer is removed under local anesthesia in an office setting and microscopic sections are prepared on slides while you wait. Your Mohs surgeon examines the slides to determine if all the cancer cells have been removed. If not additional layers are taken until the cancer is completely excised. The advantage of this technique is that a minimum amount of tissue is removed and all the edges of the specimen are carefully studied. This method has a high cure rate, but is not required for all skin cancers. In general, most dermatologists agree that recurrent skin cancers (skin cancers that were previously treated and have come back, incompletely removed skin cancers, large skin cancers, and skin cancers in cosmetically important areas), may benefit from the Mohs technique. After the skin cancer has been removed using this method, it maybe allowed to heal naturally or reconstructive surgery using a skin flap or skin graft may be performed.

Moles: Everyone has moles (also known as "nevi"), sometimes 40 or more. Most people think of a mole as a dark brown spot, but moles have a wide range of appearance. They can be raised from the skin and very noticeable, they may contain dark hairs, or they may be dangerous. Moles can appear anywhere on the skin, alone or in groups. They are usually brown in color and can be various sizes and shapes. The brown color is caused by melanocytes, special cells that produce the pigment melanin. Moles probably are determined before a person is born. Most appear during the first 20 years of a person's life, although some may not appear until later in life. Sun exposure increases the number of moles. Each mole has its own growth pattern. At first, moles are flat and tan, pink, brown or black in color, like a freckle. Over time, they usually enlarge and some develop hairs. As the years pass, moles usually change slowly, becoming more raised and lighter in color. Some will not change at all. Most moles will slowly disappear, seeming to fade away. Others will become raised so far from the skin that they may develop a small "stalk" and eventually fall off or are rubbed off. This is the typical life cycle of the common mole. These changes occur slowly since the life cycle of the average mole is about 50 years. Moles may darken, with exposure to the sun. During the teen years, with birth control pills and pregnancy, moles often get darker and larger and new ones may appear.

Molluscum contagiosum: Molluscum contagiosum is a common skin disease caused by a virus which affects the top layers of the skin. The name molluscum contagiosum implies that the virus develops growths that are easily spread by skin contact. Similar to warts, this virus belongs to the poxvirus family and enters the skin through small breaks of hair follicles. It does not affect any internal organs. Molluscums are usually small flesh-colored or pink dome-shaped growths that often become red or inflamed. They may appear shiny and have a small indentation in the center. Because they can spread by skin-to-skin contact, molluscums are usually found in areas of skin that touch each other such as the folds in the arm or the groin. They are also found in clusters on the chest, abdomen, and buttocks and can involve the face and eyelids.

Mycosis Fungoides: A form of Cutaneous T-Cell lymphoma (CTCL).
