What is a steatoma?

A steatoma is defined as a sebaceous cyst that contains sebum, which is an oily substance produced by sebaceous glands in the skin. These cysts are formed when a sebaceous gland becomes blocked and accumulates sebum, leading to the formation of the cyst. Steatomas can occur in various locations on the body, particularly the scalp, neck, and trunk.

Understanding the composition and nature of a steatoma is crucial for skincare specialists as it can help in differentiating between various skin lesions. Sebaceous cysts are generally benign and may not require treatment unless they become inflamed, infected, or for cosmetic reasons.

Recognizing that a steatoma is not a type of tumor, an infection, or a form of acne is important in clinical practice. Tumors suggest abnormal growth of tissue, while infections, which could involve bacteria or viruses, present differently in terms of symptoms and treatment. Acne typically involves inflammation and is associated with blocked follicles rather than the cystic formation characteristic of a steatoma. Thus, option B accurately captures the essence of what a steatoma is in the context of skin health and lesions.
