1. Ulcers, Sinuses and Fistulas Flashcards
Define an ulcer.
An ulcer is a tissue defect characterised by loss of continuity of epithelium on the skin/mucous membrane due to molecular death of the tissue.

- Others
State 3 types of Specific Ulcers.
- Tuberculous Ulcers
- Syphilitic Ulcers
- Actinomycotic Ulcer
State 4 types of ulcers with a malignant aetiology.
- Basal Cell Carcinoma
- Squamous Cell Carcinoma
- Malignant Melanoma
- Others
State the 6 parts of an Ulcer.
- Margin
- Edge
- Floor
- Base
- Discharge
- Surrounding skin
Define the ‘Margin’ of an ulcer.
Margin is the border/transitional zone of skin around an Ulcer.
Define the ‘Edge’ of an ulcer.
Edge is the mode of union between the Margin and Floor of the Ulcer.
Define the ‘Floor’ of an ulcer.
Floor is the exposed surface of the Ulcer
State the 5 types of edges seen in an Ulcer.
