SURGICAL DERMATOLOGY
Mohs micrographic surgery is a specific surgical technique for the treatment of certain skin tumor types that allows to achieve maximum therapeutic efficacy (close to 100%) while preserving the as much healthy tissue as possible.
This modality allows the excision and study of the entire excised sample by stages or stages until complete tumor excision is achieved.
Most of the tumors treated with Mohs surgery fall into the category of non-melanoma skin cancer, the most frequent being basal cell carcinoma and superficial forms of dermatofibrosarcoma protuberans.
This technique involves excising skin injuries with predetermined margins of clinically normal tissue around the injuries, followed by a postoperative histological examination of the excised specimen.
Unlike Mohs surgery, the main disadvantage of conventional surgery is the inability to examine the entire margins of the injuries (both peripherally and in depth) and the removal of a greater amount of healthy tissue around it.
The technique of pinch grafting is used specially in the treatment of chronic ulcers of different causes or usually located on the legs. The technique consists of the transplantation of small pieces of shaved superficial skin, from another body area of healthy skin, to the skin injury that we want to treat in order to be able to close the wound.
The cryosurgery consists of the destruction of tissue by freezing. It is a widely used technique in dermatological consultation, simple to perform, effective and with good cosmetic results. It is generally used to treat superficial skin injuries, whether benign or malignant.
Electrosurgery is a minor dermatological surgery technique that we often use in our practice to provide cutting or destruction of superficial skin tissue using an electrosurgical or electrical scalpel.
We usually use the electric scalpel for the treatment and elimination of benign skin injuries and some very superficial malignant injuries in certain patients.
Skin biopsy consists in obtaining a skin sample for diagnostic purposes and at the same time, on some occasions, allows treating a specific isolated skin injury.
In many occasions, the histopathological examination of the skin sample extracted will offer us an exact or very approximate diagnosis of a certain disease and, in this way, we will be able to propose the most appropriate treatment to the patient.
It is a useful technique especially when we are faced with isolated nail injuries, and in patients who do not have typical skin injuries from which a diagnosis could be made more easily.
The objective of the nail biopsy is to achieve an accurate diagnosis of the pathology of the nail through a simple and safe surgical procedure that allows to direct the treatment in an appropriate way.
Photodynamic therapy is a non-invasive treatment modality that is used for the selective elimination of certain superficial types of skin cancer.
It is technique that offers very good cosmetic results, causing minimal damage to the surrounding skin, as it only targets cancer cells (or neoplasms).
