Crusta

From WikiMD's Food, Medicine & Wellness Encyclopedia

Crusta is a term used in medicine to describe a type of skin lesion that is characterized by a hardened layer of skin or mucous membrane that is formed by the drying of body fluids such as blood, serum, or pus. Crusta is often associated with various skin diseases and conditions.

Definition[edit | edit source]

Crusta is derived from the Latin word for "crust" or "shell". In medical terminology, it refers to a type of skin lesion that is formed by the drying of body fluids on the skin or mucous membranes. These fluids can include blood, serum, or pus, and the crusta can vary in color depending on the type of fluid that has dried.

Causes[edit | edit source]

Crusta can be caused by a variety of skin diseases and conditions. These can include:

  • Dermatitis: This is a general term for inflammation of the skin. Dermatitis can cause the skin to become itchy, red, and swollen, and in some cases, it can lead to the formation of crusta.
  • Impetigo: This is a highly contagious skin infection that is caused by bacteria. Impetigo can cause red sores that burst, ooze, and then dry to form a yellow-brown crust.
  • Eczema: This is a condition that makes the skin red and itchy. Eczema can cause the skin to become dry, cracked, and scaly, and in severe cases, it can lead to the formation of crusta.

Treatment[edit | edit source]

The treatment for crusta depends on the underlying cause of the condition. In general, the goal of treatment is to relieve symptoms, prevent infection, and promote healing of the skin. Treatment options can include:

  • Topical medications: These are creams, ointments, or lotions that are applied directly to the skin. Topical medications can help to relieve itching, reduce inflammation, and promote healing.
  • Oral medications: These are pills or liquids that are taken by mouth. Oral medications can help to relieve symptoms, treat infections, and reduce inflammation.
  • Phototherapy: This is a type of treatment that uses ultraviolet light to reduce inflammation and promote healing of the skin.
