SKIN TUMORS

In this paper we will talk about the most common skin tumors such as benign, premalignant and malignant. Among the pathologies that are considered benign we have common warts, solar keratosis and senile hyperkeratosis. These entities, although they tend to be annoying for the patient from an aesthetic or appearance point of view, do not medically represent any danger to the individual who suffers from them. Common warts appear most frequently in places of bending or rubbing, face, hands, legs, soles of the feet and body. Classified into plants, pedunculated and acuminate, they tend to grow quickly and increase rapidly in number, so it is advisable to treat them as soon as possible. There are various treatments to control these entities, we have cryogenic agents such as carbonic snow, nitrous oxide and liquid nitrogen which allow us to remove the injury through a cold burn, which must be applied weekly until its complete disappearance. Various topical preparations have been used such as salicylic acid and podophyllin, however both commercial products produce a significant burn at the edge of the lesion. We have seen repeatedly that when the wart or keratosis is large, these products do not penetrate the deep layers of the dermis, causing a residual. On the other hand, we have electrofulguration, which will allow us to burn the injury using a device called electrofulguration, which emits low-frequency electric current through a pencil that has a Teflon conductor at the tip. Another procedure is CO2 laser that burn these lesions in one session. The advantage of this procedure is that in a single session all warts can be removed. Regarding senile hyperkeratosis and seborrheic keratoses, it is worth mentioning that although they are similar entities, the difference between them is that the former appear after the age of 50 and the latter in young adulthood, being caused by excess of fat in the skin. The ideal treatment for both entities is through the cryogenic agents, laser, IPL and astringent lotions can be used if the case warrants it.
