3 Integumentary Regions Skin –Epidermis –Dermis Hypodermis Sensory receptors Muscle Adnexa –Hair and follicle –Glands Sweat Sebaceous –Nails

4 Epidermis Histology Overview

5 Epidermis Strata Histology C = corneum G = granulosum S = spinosum B = basale

6 Underlying Disorders Genetic Connective tissue Blood supply Neoplasia Drug Reactions Immune

7 Primary Lesions Macules: colored circumscribed flat area, size varies, < 1cm Papules: discolored raised area, < 2cm Plaques: raised flat top area, > 1cm Patches: circumscribed flat area of discoloration, < 1cm Nodules: solid raised area, above or below skin, <1 cm Tumor: discolored raised area, > 2cm Wheals: slightly raised area with edema, size varies Vesicles/Blister: fluid filled raised area < 0.5cm Bulla/Cyst: fluid filled raised area, > 0.5cm Pustules: pus-filled raised area, size varies
