A nevus spilus, also known as a "speckled lentiginous nevus," is a type of pigmented skin lesion that is characterized by a tan or light brown background patch with darker spots or macules scattered within it. This condition is generally benign and is considered a type of congenital melanocytic nevus.
Characteristics[edit]
Nevus spilus typically appears as a flat, light brown patch on the skin, which can vary in size from a few millimeters to several centimeters. Within this patch, there are multiple darker macules or papules that can range in color from dark brown to black. These darker spots are often described as "speckled" or "flecked," giving the nevus its distinctive appearance.
Development[edit]
Nevus spilus can be present at birth or develop during childhood or adolescence. The background patch may enlarge over time, and additional darker spots may appear. The exact cause of nevus spilus is not well understood, but it is thought to result from a localized increase in melanocytes, the cells responsible for producing melanin, the pigment that gives skin its color.
Diagnosis[edit]
The diagnosis of nevus spilus is typically made based on its characteristic appearance. A dermatologist may use a dermatoscope to examine the lesion more closely. In some cases, a biopsy may be performed to rule out other conditions, such as melanoma.
Management[edit]
In most cases, nevus spilus does not require treatment, as it is a benign condition. However, regular monitoring by a healthcare professional is recommended to detect any changes that might suggest malignant transformation. If there are any suspicious changes, such as rapid growth, change in color, or irregular borders, further evaluation may be necessary.
