Seborrheic keratoses

Seborrheic keratoses are wart-like changes of the skin that usually appear on bodies of female patients, and especially on the area around the breasts and on the neck. With persons who have been exposed excessively to sunlight during their lifetime they appear on the face and on the hands and are mostly flattened, almost at the skin level. Sometimes they look much like moles.

Although they may reach the size of a few centimeters and be of gray and black discoloration, these are completely benign changes. To make a first diagnosis it is necessary to be examined by a dermatologist. If the dermoscopic skin examination shows that changes correspond to seborrheic keratosis, its removal is very simple and superficial and is conducted exclusively for esthetic reasons. In large keratotic changes in the base of the keratosis there can be a mole or some other lesion and then it’s necessary to send the sample to a pathohistological analysis.

After removing the seborrheic keratoses by radio waves no scars remain, and there can eventually be a white discoloration on the skin.

Actinic keratoses

Actinic keratoses are changes in the skin that come from UV radiation damage, that is, from long term sunbathing and using tanning booths. Typical place of appearance are the face, ear lobes and scalp. They are characterized by red thinned skin with a thin scab that doesn’t heal. Basically this is precancerosis, the cells are atypical and connected to the surface skin structures. During the years, if the change is not removed, a planocellular carcinoma may occur.
