Lesson title = Pustule

This is lesson 10 of 18 in this module
Pustule
A primary morphology

Definition:
  • Palpable: yes
  • Size: generally less than 1cm but can be bigger
  • Colour: usually white or yellow, filled with purulent (pus) fluid

General Explanation for a Pustule:
  • Collection of fluid, most often pus (dead white blood cells), that tends to occur in the epidermis. Think of a pustule as a vesicle but filled with pus.
  • Of note, you can get:
    • “Follicularly centred” pustules:
      • Pustules around a hair follicle
    • "Non-follicularly centred" pustules:
      • pustules that arise anywhere and do not need to be associated/around a hair follicle.

Examples:
  • Follicularly centred pustules:
    • Acne vulgaris = acne pustules
    • Folliculitis = Infection of hair follicles, most often with bacteria
  • Non-follicularly centred pustules:
    • Pustular psoriasis = unique form of psoriasis that presents with pustules, most often on the palms and soles
    • Acute generalized exanthematous pustulosis (AGEP) = Generally thought of as a type of drug eruption
