Anetoderma is a rare skin condition that is characterized by areas of loss of elastic fibers and collagen in the skin, resulting in areas of soft, flaccid skin. In this article, we will define anetoderma and its various types, including primary and secondary anetoderma, as well as provide an overview of the causes, symptoms, diagnosis, and treatment options available for those living with this condition.
Anetoderma is a dermatological condition that is characterized by the loss of elastic fibers and collagen in the skin, leading to the formation of depressions or flaccid areas of skin. The condition can occur in isolated areas or in a widespread pattern on the skin. Anetoderma is a rare condition, with an estimated incidence of 1 in 20,000 individuals worldwide.
Types of Anetoderma
There are two types of anetoderma: primary and secondary. Primary anetoderma is a rare, idiopathic condition that is not associated with any underlying medical condition. Secondary anetoderma, on the other hand, is a condition that is associated with an underlying medical condition or exposure to certain medications or environmental factors.
Primary Anetoderma
Primary anetoderma is further divided into two types:
Jadassohn-Pellizzari Anetoderma
Jadassohn-Pellizzari anetoderma is characterized by the presence of multiple small, flaccid, round or oval-shaped lesions on the skin. These lesions are typically 5mm in diameter or smaller and are often found on the trunk and upper arms. The cause of Jadassohn-Pellizzari anetoderma is unknown, and the condition is not associated with any underlying medical condition.
Schweninger-Buzzi Anetoderma
Schweninger-Buzzi anetoderma is characterized by the presence of larger, single, depressed areas on the skin that are typically 1 to 10cm in diameter. These areas are often found on the trunk and upper arms and are more common in women than men. The cause of Schweninger-Buzzi anetoderma is unknown, and the condition is not associated with any underlying medical condition.
Secondary Anetoderma
Secondary anetoderma is associated with an underlying medical condition or exposure to certain medications or environmental factors. Some of the common causes of secondary anetoderma include:
- Infection: Infections such as syphilis, tuberculosis, and leprosy can lead to the development of anetoderma.
- Connective tissue disorders: Conditions such as systemic lupus erythematosus (SLE) and scleroderma can cause anetoderma.
- Autoimmune disorders: Autoimmune disorders such as autoimmune hepatitis and primary biliary cirrhosis can lead to the development of anetoderma.
- Exposure to medications: Certain medications, such as penicillin, can cause anetoderma.
- Exposure to environmental factors: Exposure to environmental factors such as UV radiation and heat can lead to the development of anetoderma.
Causes
Here are the known causes of anetoderma:
- Genetics: In some cases, anetoderma can be inherited genetically.
- Autoimmune disorders: Autoimmune disorders such as systemic lupus erythematosus and scleroderma can lead to anetoderma.

Diagnosis
Diagnosing anetoderma can be challenging because the symptoms can be similar to those of other skin conditions. However, there are several tests and diagnostic criteria that can help to confirm a diagnosis of anetoderma and diagnosis and tests for anetoderma in detail.
- Clinical Examination – The first step in diagnosing anetoderma is a clinical examination. A dermatologist will examine the skin for the presence of small, soft, round, or oval-shaped depressions, which are the hallmark of anetoderma. The dermatologist may also look for other signs of skin damage, such as scarring or discoloration.
- Biopsy – A skin biopsy involves removing a small piece of skin tissue for examination under a microscope. This can help to confirm a diagnosis of anetoderma and rule out other skin conditions. The biopsy will show a loss of elastic fibers and thinning of the dermis.
- Histopathological Examination – A histopathological examination is a type of biopsy that involves examining the skin tissue under a microscope to look for changes in the skin structure. In anetoderma, the examination may reveal a loss of elastic fibers in the skin.
- Immunofluorescence – Immunofluorescence is a test that involves using fluorescent dyes to label antibodies or other molecules in the skin tissue. This can help to identify any autoimmune disorders that may be contributing to the development of anetoderma.
- Skin Culture – A skin culture involves taking a sample of skin tissue and testing it for bacterial or fungal infections. This can help to rule out any infectious causes of skin damage.
- Blood Tests – Blood tests can be used to identify any underlying medical conditions that may be contributing to the development of anetoderma. These may include autoimmune disorders or infections.
- Genetic Testing – Genetic testing can help to identify any genetic mutations that may be contributing to the development of anetoderma. This can be particularly useful for individuals with a family history of the condition.
- Ultrasonography – Ultrasonography uses high-frequency sound waves to create images of the internal structures of the body. In anetoderma, ultrasonography can be used to assess the thickness of the skin and to look for any abnormalities in the connective tissue.
- Magnetic Resonance Imaging (MRI) – MRI uses a magnetic field and radio waves to create detailed images of the body. This can be useful in identifying any structural abnormalities in the skin and underlying tissues.
- Computed Tomography (CT) – Scan A CT scan is a type of X-ray that uses multiple images to create a detailed image of the body. This can be useful in identifying any structural abnormalities in the skin and underlying tissues.
- Skin Elasticity – Measurement Skin elasticity measurement involves using a device to measure the elasticity of the skin. This can be useful in assessing the severity of anetoderma and tracking any changes over time.
- Skin Biomechanical Testing – Skin biomechanical testing involves using a device to measure the mechanical properties of the skin, such as its strength and flexibility. This can help to assess the severity of anetoderma and track any changes over time.
- Skin Surface Measurement – Skin surface measurement involves using a device to measure the texture
