I'm researching information about a skin condition with these characteristics: [APPEARANCE]: (Color, texture, size, etc.) [LOCATION]: (Where on the body it appears) [SENSATION]: (Itchy, painful, no sensation, etc.) [DURATION]: (How long it has been present) [PATTERN]: (Constant, comes and goes, spreading, etc.) [TRIGGERS]: (What seems to cause or worsen it, if known) [OTHER FACTORS]: (Any other relevant details) Please help me organize research about skin conditions by: 1. Creating a structured comparison of different skin conditions that might have these characteristics 2. For each potential condition, providing: - Distinctive features and typical patterns - Common triggers and influencing factors - Key information points to understand 3. Organizing a list of specific factors that would be helpful to track about skin changes 4. Suggesting reliable dermatology information sources for further research Please emphasize that this is for informational research only and not medical advice or diagnosis. Remind me that proper dermatological evaluation is important for skin conditions.
