Psoriasis can be hard to diagnose – when to consult a doctor
Summary
- Psoriasis often mimics other skin disorders such as eczema, fungal infections and lichen planus, leading to diagnostic confusion.
- Typical lesions are well‑defined red plaques covered with silvery‑white scales, commonly appearing on elbows, knees, scalp and lower back.
- Definitive diagnosis may require a dermatologist’s assessment and, in doubtful cases, a skin biopsy to rule out other conditions.
- Medical attention is advised when lesions are painful, rapidly spreading, or associated with joint pain suggestive of psoriatic arthritis.
- Early detection and appropriate therapy can limit disease progression and improve patients’ quality of life.
