Transcript INTEGUMENTARY SYSTEM

Overview of
Integumentary
Disorders
Disorders of the Nails Disorders
 Clubbing – abnormal curving / increased angle at the
nail bed (often related to O2 deficiency)
 Koilonychia– “spoon nail” = malformation of the nail in
which the outer surface is concaved or scooped out
(often indicates iron deficiency anemia)
 Onychia/Onychitis (onych = fingernail) = inflammation
of the matrix of the nail
 Onychocryptosis (onych = mail, crypt = hidden, osis =
abnormal condition)
NDisorders of the Nails
Continuedil Diseases and Disorders
 Onychomycosis = fungal infection of the nail
(myc= fungus)

margins of a nail (par = along side)
 Subungual hematoma – collection of blood
under a nail
HaiDisorders of the Hairr Diseases

 alopecia universalis
 Female pattern baldness – hair thins in front and sides
 Male pattern baldness- Horseshoe shape area of hair
remains in the back and temples
Disorders of the Skin
