Skin wounds, rigidity and incrustation which do not recover for a long time may be a sign of skin tumors. Great majority of these tumors are harmless and simple masses named as benign tumors. Besides nevi associated with pigment cells of skin, such simple tumoral structures as fatty tissues, connective tissues or muscular tissues originating from tissues inside or close to skin stay in the body by slowly growing in a long time. Sometimes, they cause pain, sensitivity and similar other disturbances due to mass effect. From time to time, they may get inflamed, grow up and cause a discharge.

Nevi: Almost everyone has a great many nevi. Large nevi with a diameter of more than 1 cm are highly probable to develop a tumor. Patients with a history of malign skin tumor in their family and who continue to produce nevi with side irregularities and pigment irregularities may specifically be under risk. Sudden changes in small nevi are also important medically. In the case of sudden growth, itching, bleeding or pigment changes, you have to take medical help as soon as possible. An extremely bad tumor named malign melanoma may develop on nevi. At early stages, it may be fully treated, but at delayed stages, it may be helpless.

Do not ever have your nevi scorched by laser, cautery or chemical agents. Appropriate surgical interventions will give the most reliable and best aesthetic results with not much disturbance to you.

Benign masses: The existing masses must be examined and followed up or surgically excised by a specialist.

Malign masses: The most common type of malign masses is sun-related ones. A person with a light skin color must be protected from sun all his life. Some skin tumors develop insidiously. All kinds of wounds which do not heal within a few weeks must absolutely be assessed in terms of skin tumor. Malign skin tumors may develop through transformation of existing nevi, on burn zones, in non-healing wounds and on zones exposed to friction at all times. A pathologic examination must be performed thereon without delay. If deemed necessary, a surgical excision is applied. For some tumor types, it may be required to clean lymph nodes. To this end, lymph nodes may be marked by special methods. This is called "sentinel lymph-node marking".
