o Example - freckles, measles, rubella, roseola, café-au-lait macule of tuberous
sclerosis
• Patch
o Larger flat area of altered colour or texture
o Example - depigmented patch of vitiligo
• Papule
o A small raised lesion
o Example - allergic, inflammatory papules of acne
• Maculopapular
o Combination of macules and papules
o Example - measles, scarlet fever, parvovirus B19 (erythema infectiosum, fifth
disease)
• Plaque
o A larger raised lesion
o Example - scaly plaque of psoriasis
• Nodule
o A larger raised lesion with a deeper component (involvement of the dermis or
subcutaneous fat)
o Example - nodular lesion of erythema nodosum
• Vesicle
o A small clear blister
o Example - varicella
• Bulla
o A large clear blister
o Example - skin trauma, bullous impetigo
• Wheal/weal
o A transient raised lesion due to derma oedema
o Example - urticaria (hives)
• Pustule
o A pus containing blister
o Example - acute paronychia
• Purpura
o Bleeding into skin or mucosa. Small areas are petechiae, whereas large areas are
ecchymoses. Do not blanch on pressure

Skin anatomy
Epidermis:
• Closely packed layers of Keratinocytes (85%) adherent to eachother by desmosomes and
dermis through basal membrane called Lamina densa
• Horny layer consists of dead cells bound by lipid
• 60 day transit time from basal layer to the surface
