Algorithm for comprehensive clinical detection and differential diagnosis of skin lesions. We use only 5 morphologically very easy to grasp descriptions of findings for the definition of the conduction fluorescence:
- Spots
- Sublime
- Deepening
- Hardenings
- Bearings.
- Stains: Non palpable colour changes of any kind. The stains belong together with the raised areas to the largest "efflorescence group". Their clinical differentiation is often important for diagnostic reasons. A spot is merely a colour change in the skin. With a spot, the examiner does not feel any change in the consistency of the skin.
- Elevations are divided into non-solid (prototype: blister) and solid elevations (prototype: papule):
- Blister, blister, pustule
- Papule (circumscribed skin roundness < 0,5 cm)
- Plaque (the plaque is a term for a flat raised area, e.g. psoriasis plaque)
- Nodules (circumscribed tissue consolidation lying in the skin or subcutis or protruding above the skin level > 0.5 cm)
- wheals (acute, volatile, cutaneous edema)
- Swelling (acute or chronic subcutaneous oedema with or without tissue proliferation).
- Depressions:
- scar
- Atrophy
- Erosion
- Ulcer
- Crack (Rhagade).
- Indurations (hardenings): superficial or deep, flat or knotty tissue hardening which can only be palpated.
- Deposits (scaling, crusts, fluid).
