2 steps in establishing morphology of any given skin condition
-1. careful visual and tactile inspection
-2. application of correct descriptors
lesion shape
Nummular/Discoid/Round: all describe coin-shaped lesions
Annular: ring-shaped
Arcuate: shaped like an arc.
Serpiginous: wavy like a snake
Figurate/Polycyclic: lots of different ring shapes, rings within rings
Retiform/Reticulate: web or net-like.
Mammillated ‘nipple like’: bumpy, like a cobblestone road
Umbilicated: centrally indented
Targetoid: lesions with a bulls-eye, or concentric rings or varying colors
distribution
Discrete/Scattered: lesions are separate from one another
Clustered (Agminated): grouped together in a bunch but not running together
Coalescing: grouped and starting to merge into one another
Focal: just in one anatomic location
Generalized: over the ENTIRE body
nails grow
0.1mm/daily
primary lesions
-Macule, patch: Flat, color change only
-Papule, plaque: raised, palpable
-Vesicle, bulla: serous fluid-filled space in epidermis -> bulla is large vesicle
-Wheal: an edematous papule or plaque -> urticaria
-Nodule, tumor: raised lesion deeper in skin -> nodule is smaller
-tumor >5cm
-Pustule, furuncle (nonflucuent), abscess (fluccuent): pus-filled space
-Cyst: a sac-like nodule that has an epithelial lining containing fluid or debris
-petechiae is the smaller purpura (>.5cm)
secondary lesions
-Result from changes in primary lesions -> Traumatic injury to the skin or other external factors
-scale- dead skin
-lichenification- rubbing, itching, skin irritation
-keloid
-scar
-excoriation- loss of epidermis, scratch
-fissure- crack
-erosion- after rupture of vesicle or bulla
-ulcer- loss of dermis
-crust- dried fluid
-atrophy- stretch mark
annular
-circular rashes with central clearing
distribution vs configuration
-distribution- location
-configuration- means how the lesions are arranged or relate to each other
clubbed fingers
-float
-warm fingers, redish tinge
-nail curves down- spoon
-lung cancer
-heart defect- congenital
-lung infections
-anemia
schamroths sign
-diamond window between fingers
-sign of clubbing
spooned nails
-koilonychia
-nails curve inwards
-soft and thin
-causes- autoimmune, genetics, vitamin deficiency
-iron deficiency anemia- MC
central nail ridge
-vertical ridges in nails
-typically associated with aging
-assoc with diabetes, vit deficiency
