Cutaneous tumors are an abnormal tissue alteration of a body part. Cutaneous tumors can differentiate into benign tumors (neoplasia) or malignant (cancer). Benign tumors are not usually a life threatening, they are removed and in most cases does not appear again. Cells from malignant tumors can invade and damage nearby organs and tissues.
Benign Cutaneous Tumors
Among the benign cutaneous tumors include lipomas, small angiomas, Nevus, papillomas, etc.
This type of tumors usually are operated under local anesthesia and outpatient. To remove these lesions a cut is made around with 1 or 2 mm margin. Having to draw a more or less important part of cutaneous tissue is as important as removing the suture the orifice being due to use sometimes when the lesion is large flaps or skin grafts from a donor site.
Malignant Cutaneous Tumors
These types of injuries also called Melanoma (melanocytes, which are the cells responsible for the skin coloration). This type of pigmented lesions often have changes in color, appearance, irregular edges …
For this type of skin tumors, as one of its main features is that they are very aggressive and fast growing, we must address it as soon as possible. Surgeries of this type lesions the cutting area must be greater due to the aggressive appearance of the tumor to ensure that it has left the area clean (at least 2 cm over the affected area). These surgical procedures always carries a tumor biopsy to ensure non metastization thereof.
