Spitz nevus (or Spitz nevus) is a type of benign mole with unusual behavior. It usually occurs in childhood or adolescence and is characterized by rapid growth and a tendency to bleed.
When examined microscopically, this type of mole looks very similar to melanoma, but is not melanoma.
In the mid-20th century, scientists called this nevus "juvenile melanoma." The Spitz nevus was named after the American pathologist Sophie Spitz, who described it in 1948.
Spitz nevus mainly occurs in children and adolescents without any sexual preference. It occurs in 1.4 cases per 100,000 population and usually appears on the face and neck, but can be on the legs.
This type of mole is a single nodule with a diameter of 0.2 to 2 cm with a smooth or warty surface.
It has a uniform pink or light brown color, clear borders and a dense structure. In addition, Spitz nevus can bleed with the slightest injury.
Oncologist of the 1st category of the HappyDerm medical center Lyudmila Artyushkevich notes that the Spitz nevus appears suddenly and does not cause any unpleasant sensations, but grows quickly. It is the rapid growth of the mole that usually makes patients seek advice from a dermatologist or oncologist. Although malignant degeneration is rarely observed, it is not excluded, especially with the onset of puberty.
Diagnostics
To diagnose Spitz nevus, various methods are used, which include:
- patient survey;
- inspection;
- performing dermatoscopy of a mole;
- histological examination of the removed nevus.
Treatment
Removal of Spitz nevus is performed surgically with a healthy skin reserve of 5 to 10 mm. If the removal is incomplete, there is a risk of relapse (10-15%). Histological examination of the removed nevus is mandatory.
In the postoperative period, the patient is observed for a year.
Spitz nevus is a benign formation, but its tendency to malignant transformation requires increased attention.
If you or your child has a rapidly growing and changing mole, you should see a dermatologist/oncologist for diagnosis and treatment options.
The skin is the largest organ in humans, on the surface of which various formations can appear, including nevi (moles).
Moles can have different appearances and colors, remain unchanged or grow and change before your eyes. Some moles are safe, while others may be prone to degeneration into a malignant tumor.
Spitz nevus, as a benign birthmark with unusual behavior, requires special attention and monitoring by specialists.
