Dermatology and Pruritus Ani

Chapter

Abstract

  • Accurate description of the morphology of skin lesions aids in diagnosis and follow-up of patients with pruritic complaints.

  • Macules are flat spots.

  • Papules are elevated circumscribed solid lesions.

  • Vesicles are separations of the epidermis from the dermis filled with serum.

  • Bullae are larger vesicles or blisters ≥10 mm.

  • Pustules contain pus.

  • Ulcers are surface lesions with loss of continuity of the skin and may result from rupture of vesicular lesions, infection, or trauma.

  • Intertrigo is inflammation seen between two opposing skin surfaces, often the result of mixed bacterial and fungal infections – associated with moisture, obesity, and poor hygiene.

  • Pruritus or itch is the unpleasant sensation that provokes the desire to scratch.
