These conditions are characterized by the formation of rough, dry, and scaly patches or bumps on the skin due to abnormal accumulation of keratin.
Furthermore, keratose can also be utilized in a broader sense to describe any substance, material, or structure that resembles or contains keratin. For example, keratose can be found in certain types of fungi, sea sponges, or in the outer covering of some insects.
