Question: 1 / 400

What is the term for a dry, scaly skin condition resulting from a deficiency of sebum?

Dermatitis

Eczema

Asteatosis

The term that describes a dry, scaly skin condition resulting from a deficiency of sebum is indeed Asteatosis. Sebum is the natural oil produced by sebaceous glands in the skin, and it plays a crucial role in keeping the skin moisturized and protected. When there is a deficiency in sebum production, the skin can become dry, leading to conditions like asteatosis, which is characterized by a lack of moisture and can result in scaling and flaking of the skin.

Dermatitis refers to inflammation of the skin and can manifest in various ways, often with redness and itching, but it is not specifically linked to a deficiency of sebum. Eczema is a broader term for various chronic skin conditions that cause inflammation and irritation but again does not exclusively pertain to the lack of sebum. Anhidrosis is a condition characterized by an inability to sweat, which is unrelated to sebum production.

Therefore, understanding the specific relationship between sebum deficiency and skin conditions helps clarify why asteatosis is the correct term for the dry, scaly skin condition in question.
