The word nevus or nevus (Latin naevus, mole) refers to a proliferation of different cell types in the skin. The most typical are melanocytic nevi that are pigmented cell proliferations.
The Nevus Rufus or red spots, also known as Nevus Ruby, Ruby Points, Nevus or Moles Blood Cherry. Benign moles are listed older subjects, skin aging, men and women, usually in the chest, neck and arm. They are usually circular, red and of one or two millimeters in diameter.
Many are also in fair-skinned people.
His appearance is a vascular dilation of small superficial blood vessels.
May appear for liver disorders or imbalances, normal aging of the skin, prolonged exposure to sunlight and inadequate, often appear during pregnancy, but usually disappear when the woman gives birth.Treatment:
The most modern is laser therapy. The most appropriate laser has wavelengths ranging from 532, 980 and 1064 nm.
Laser light energy is absorbed by hemoglobin nevus which produces immediate coagulation thereof.
This treatment does not require anesthesia, is fast and the patient continues with his normal life immediately.
The aesthetic result is extraordinary.
Melanocytic nevus are common benign skin lesions that are found in almost all of the population.
They might be flat or elevated , asymptomatic, with well defined edges, regular color and frequently small in diameter (<6 mm in diameter). Initially, the nevus cells are located between the epidermis and the dermis ( dermal- epidermal junction ) and are called junctional nevus or Union. At that moment flat lesions are dark brown or black in color. As time passes, the groups of melanocytes ( teak ) proliferate and extend into the dermis , which are called compound melanocytic nevus. The color of melanocytic nevus varies with the location of the related pigment (melanin).
If the majority of pigmented cells are found in the epidermis ( skin surface area ) the will be brown color , while if it is located on the epidermis and superficial dermis will be black , or dark brown, and if nevus melanocytes ( nevus cells ) are located in the deep dermis , the lesion assumes a bluish color (blue nevus). The number of melanocytic nevus that develops a person throughout his life is variable and is influenced by genetic and environmental factors (especially skin that has been exposed to sun). The melanocytic nevus are dynamic blooms that change throughout life. They tend to darken with sun exposure or during pregnancy and in adulthood tend to gradually lose their pigmentation and may even disappear in old age.
Types of melanocytic nevus.
A) BIRTH melanocytic nevus.
They may be of varying size, ranging from a few millimeters up to large part of the body surface. They split in congenital melanocytic nevus which are empirically small , mid-size and giant . Described an increased risk of developing malignant melanoma especially in melanocytic nevus.
B) ACQUIRED melanocytic nevus.
These are lesions of size, color , variable number . They are well defined and regular in coloring. They may be flat or raised. They tend to be more abundant in areas exposed to the sun.
C ) ATYPICAL nevus.
Atypical nevus are moles with irregular borders , diffuse colored and/or large in size. These patients require periodic dermoscopic and clinical controls. Preventive surgery is paramount. Whenever possible these injuries should be removed surgically and sent to a dermatopathologist to perform a proper diagnosis.
