Of course. This is a helpful and well-organized guide to various dermatological (skin) conditions and lesions.
Here is a breakdown and a slightly reorganized summary of the information presented in the image:
Summary of Skin Issues
The guide categorizes and defines 12 common skin issues, ranging from temporary lesions to chronic conditions.
1. Lesions with Fluid or Pus
· Pustule: A small, raised bump on the skin that contains pus.
· Vesicle: A small, fluid-filled blister (the guide defines a pustule as a vesicle that has become filled with pus).
· Ulcer: An open sore on the skin or mucous membrane, often accompanied by the slow loss of tissue.
2. Texture and Elevation Changes
· Fissure: A deep crack or split in the skin.
· Papule: A small, solid, raised bump on the skin.
· Tumor: A solid mass of tissue; can be benign (non-cancerous) or malignant (cancerous). In dermatology, it refers to any abnormal swelling or growth.
· Scales: Flakes of dead skin cells that form a visible layer, often associated with Psoriasis.
· Scar: The pale, fibrous tissue that forms after a wound or injury has healed.
3. Changes in Skin Color
· Erythema: Redness of the skin, caused by increased blood flow to the capillaries.
· Cyanosis: A bluish or purplish discoloration of the skin, due to low oxygen levels in the blood.
· Vitiligo: A condition characterized by patches of skin losing their pigment (melanin), resulting in white patches.
4. Specific Conditions and Severe States
· Eczema: A general term for a group of conditions that cause the skin to become inflamed, itchy, and red.
· Necrosis: The death of body tissue, often due to a lack of blood supply or infection.
