Skin Examination Flashcards
What framework should be used to describe a rash and a lesion?
Rash:
Distribution (where is it)
Configuration (groups, lines, random)
Morphology (what sort of lesion)
Pigmented lesion: Asymmetry Border Colour (Diameter) (Elevation)
Non pigmented lesion: Site Size Shape Surrounding tissue
What do the following distributions refer to: acral, dermatomal. flexor, extensor, generalised, follicular, photosensitive, seborrhoeic, truncal, unilateral?
Acral: Distal portion of areas, hands, feet, nose, ears.
Dermatomal: Follows the areas of a dermatome.
Flexor: Only on flexor surfaces.
Extensor: Only on extensor surfaces.
Generalised: Universally distributed.
Follicular: Arising from hair follicles.
Photosensitive: Arises from sunexposed areas.
Truncal: Favours the trunk not on the limbs.
Unilateral: Eruption only on one side of the body.
Seborrhoeic: Affecting oily skin, Scalp, behind ears, eyebrows, nasolabial folds, sternum and interscapular.
Herpetiform clusters:
What are the different configurations you can have?
Discoid (coin shaped) Annular (grouped in a circle or oval) Linear Gyrate (appears to be whirling in a circle) Target lesions
Describe the following terms, macule, papule, nodule, plaque, vesicle, bulla, pustule?
Macule: a non palpable area of colour change
Papule: a palpable mass less than 0.5cm in diameter
Nodule: a palpable mass which is greater than 0.5cm
Plaque: a flat topped palpable lesion
Vesicle: a papule filled with clear fluid
Describe the following terms, telangiectasia, purpura, petechia, ecchymosis, fissure, lichenification?
Telangiectasia: Visible dilatation of small cutaneous blood vessels
Purpura: non blanching macules or papules of blood in the skin
Petechia: non blanching pinsized maccules of blood in the skin
Eccychymosis: large extravasation of blood into the skin (a bruise)
Fissure: a thin crack or slit in the skin
Lichenification: thickening of the skin due to chronic scratching/rubbing
