Lentigo simplex

Lentigo Simplex is a type of skin lesion that is characterized by small, pigmented spots on the skin. It is the most common form of lentigo, a condition that is often confused with freckles or melanoma due to its similar appearance.

Definition

Lentigo Simplex is not a cancerous condition and is not caused by sun exposure, unlike other forms of lentigo. The spots are usually less than 5mm in diameter and can appear anywhere on the body. They are most commonly found on the arms, legs, and torso.

Causes

The exact cause of Lentigo Simplex is unknown. However, it is believed to be a result of an increase in the number of melanocytes, the cells that produce melanin, in the skin. This increase in melanocytes leads to the formation of the characteristic dark spots of the condition.

Symptoms

The primary symptom of Lentigo Simplex is the appearance of small, dark spots on the skin. These spots are usually brown or black and can appear anywhere on the body. They are typically less than 5mm in diameter and have a clearly defined edge.

Diagnosis

Diagnosis of Lentigo Simplex is usually made based on the appearance of the skin. A dermatologist may use a tool called a dermatoscope to examine the skin more closely. In some cases, a biopsy may be performed to rule out other conditions, such as melanoma.

Treatment

Treatment for Lentigo Simplex is usually not necessary, as the condition is not harmful. However, some people may choose to have the spots removed for cosmetic reasons. This can be done through various methods, including laser therapy, cryotherapy, and chemical peels.
