Eccrine nevus

Eccrine nevus is a rare type of skin disorder characterized by an increased number of eccrine sweat glands. It is a type of epidermal nevus, which is a skin disorder characterized by an overgrowth of the epidermis and its appendages.

Symptoms

The main symptom of eccrine nevus is the presence of a skin lesion that is usually present at birth or appears in early childhood. The lesion is typically solitary and localized, but multiple or widespread lesions can occur. The lesion is usually asymptomatic, but it can cause mild discomfort, especially when sweating.

Causes

Eccrine nevus is caused by a genetic mutation that leads to an overgrowth of eccrine sweat glands. The exact cause of this mutation is unknown, but it is thought to occur sporadically.

Diagnosis

The diagnosis of eccrine nevus is usually made based on the clinical appearance of the skin lesion. A skin biopsy can confirm the diagnosis by showing an increased number of eccrine sweat glands.

Treatment

There is no specific treatment for eccrine nevus. Treatment is usually aimed at managing the symptoms, such as discomfort caused by sweating. This can include the use of antiperspirants or medications to reduce sweating. In some cases, surgical removal of the lesion may be considered.
