Steatocystoma Multiplex: Causes and Treatments

Steatocystoma multiplex (SM) is a rare dermatological condition characterized by the formation of multiple benign sebaceous cysts. These cysts typically appear on the trunk, upper arms, and chest and can cause significant discomfort and cosmetic concern for those affected. 

Steatocystoma multiplex is a genetic disorder involving the sebaceous glands. These glands, which are responsible for producing sebum (an oily substance that lubricates the skin), become obstructed, leading to the formation of cysts. 

These cysts are typically filled with an oily or cheese-like substance and can vary in size from a few millimetres to several centimetres.

Symptoms of Steatocystoma Multiplex

The primary symptom of steatocystoma cinema is the presence of multiple cysts, which can be asymptomatic or associated with discomfort, inflammation, and occasionally infection. Other symptoms include:

Causes of Steatocystoma Multiplex

The exact cause of steatocystoma theatre is not fully understood, but it is believed to be largely genetic. The condition is often inherited in an autosomal dominant pattern, meaning that only one copy of the mutated gene is necessary to cause the disorder.

Genetic Mutations

The condition has been linked to mutations in the KRT17 gene, which encodes keratin 17, a protein crucial for the structural integrity of the skin, hair, and nails. Mutations in this gene disrupt normal skin development and the function of sebaceous glands, leading to cyst formation.

Diagnosing Steatocystoma Multiplex

Diagnosing steatocystoma multiplex involves a thorough clinical examination by a dermatologist, who will assess the characteristic appearance of the cysts. Additional diagnostic procedures may include:

Clinical Examination

A detailed patient history and physical examination are essential. The dermatologist will look for the cysts' distinctive features and inquire about the patient's family history to identify any genetic predisposition.

Histopathological Analysis

A biopsy of the cyst may be performed to confirm the diagnosis. Histopathological analysis typically shows cysts lined by stratified squamous epithelium, with sebaceous lobules attached to the cyst wall, confirming steatocystoma multiplex.

Genetic Testing

Genetic testing can identify mutations in the KRT17 gene, helping to confirm the diagnosis and providing information about the genetic basis of the condition.

Treatment Options for Steatocystoma Multiplex

While there is no cure for steatocystoma multiplex, several treatment options can help manage the symptoms and improve the quality of life for affected individuals.

Topical Treatments

Topical retinoids and antibiotics can be applied directly to the affected areas to reduce inflammation and prevent infection. These treatments are often used in conjunction with other therapies for optimal results.
