Anetoderma maculosa is a rare skin disorder that is characterized by the development of small, circular or oval-shaped patches on the skin. These patches can be either hypo-pigmented or hyper-pigmented, and they may become depressed or raised over time. The condition usually affects young adults and is more common in females than males.
Anetoderma maculosa, also known as macular atrophy, is a rare skin disorder that affects the elastic fibers of the skin, resulting in a loss of elasticity and the formation of small, depressed areas on the skin’s surface. These areas can range in size from a few millimeters to several centimeters and may be single or multiple. Anetoderma maculosa can affect individuals of any age and gender, but it is more commonly seen in young adults.
There are two main types of anetoderma maculosa: primary and secondary.
- Primary anetoderma maculosa occurs when there is a defect in the elastic fibers of the skin. This can be due to a genetic mutation or an autoimmune disorder.
- Secondary anetoderma maculosa occurs when there is damage to the skin, such as from an infection, trauma, or exposure to certain drugs or chemicals.
Causes
Possible causes of anetoderma maculosa and provide details on each.
- Genetic mutations – Anetoderma maculosa has been linked to mutations in several genes, including the COL3A1, FBLN5, and ADAMTS2 genes. These genes are involved in the production of collagen and elastin, which are essential components of healthy skin.
- Autoimmune disorders – Some autoimmune disorders, such as lupus and scleroderma, may contribute to the development of anetoderma maculosa.
- Infections – Certain bacterial, viral, or fungal infections may trigger anetoderma maculosa. For example, tuberculosis, syphilis, and hepatitis C have been associated with this condition.
