Epitheliogenesis Imperfecta

• Also called Aplasia Cutis
• Incomplete development of squamous epithelium and adnexa of skin and epithelium of oral mucosa
• Occurs in most species
• Grossly:
  • Circumscribed areas of missing squamous epithelium
• Unprotected underlying tissue gets easily damaged and infected, possibly resulting in bacteraemia

• • There is absence of portions of the epidermis.
    • Results in ulcers.
