A comprehensive clinical examination is the basis for selecting further diagnostic steps:
- General physical examination – including blood pressure, pulse, body weight, height; furthermore:
- Inspection (viewing).
- Skin and hair [greasy scaly yellow foci; on reddened ground; these occur preferentially in the following places:
- Eyebrows
- Hairline
- Between lip and nose
- Sweat groove]
- Skin and hair [greasy scaly yellow foci; on reddened ground; these occur preferentially in the following places:
- Inspection (viewing).
- Dermatological examination [due todifferential diagnoses:
- Neurodermatitis
- Erythrasma (dwarf lichen) (redness of the skin caused by bacteria, similar to that of fungal disease).
- Erythrodermia desquamativa (generalized skin redness and scaling).
- Ichthyosis vulgaris (genetic cornification disorder).
- Impetigo contagiosa (bork lichen; pus lichen) (inflammation of the skin triggered by streptococci of serogroup A).
- Scalp eczema
- Lichen simplex chronicus (synonyms: Neurodermatitis cirumscripta, Lichen chronicus vidal or Vidal disease) – localized, chronic inflammatory, plaque-like and lichinoid (nodular) skin disease that progresses in episodes and is associated with severe pruritus (itching).
- Light dermatoses (skin changes caused by exposure to light).
- Perioral dermatitis (synonyms: Mouth rose or rosacea-like dermatitis) – skin disease with areal erythema (redness of the skin), red disseminated or grouped follicular papules (nodular change on skin), pustules (pustules), dermatitis (skin inflammation) of the face, especially around the mouth (perioral), nose (perinasal) or eyes (periocular); Characteristic is that the skin zone adjacent to the red of the lips remains free; age between 20-45 years; mainly women are affected; risk factors are cosmetics, prolonged local corticosteroid therapy, ovulation inhibitors, sunlight
- Pityriasis simplex (synonyms: pityriasis alba, pityriasis alba faciei) – a common, non-contagious, and usually harmless skin disease that occurs mainly in children; it manifests as dry, fine-scaly, pale patches that appear mainly on the face
- Pityriasis versicolor (Kleienpilzflechte, Kleieflechte) – non-inflammatory superficial dermatomycosis (skin fungal disease) caused by the pathogen Malassezia furfur (yeast fungus); sun exposure causes a whitish discoloration of the affected areas (white macules/spots).
- Pityrosporum folliculitis (inflammation of hair follicles caused by Pityrosporum).
- Psoriasis capillitii (psoriasis of the head).
- Rosacea (copper rose) – chronic inflammatory, non-contagious skin disease that manifests itself on the face; typical are papules (nodules) and pustules (pustules) andTeleangiectasia (dilation of small, superficial skin vessels).
- Diaper dermatitis – must be considered differential diagnosis of eczema in the diaper region]
- Health check
