Other Etiologies

00:01 infection and pressure relief. Other aetiologies will be just to confuse you. I don't think you will get any clinical scenario on these, but these might be some of the options. Pressure ulcers, you need to know because they are so common these days.

00:13 You need to have a good idea of pressure ulcers. Okay this is a very good exam clue. Edges or margins of the ulcer. This is exactly the word they give you. Okay, I'm sure you know this. Squamous cell carcinoma, raised and everted. Basal cell, raised and rolled out.

00:33 Tuberculous ulcers, overhanging and undermined. Punched out is trophic. And healing ulcer is sloping edge. You also get in venous ulcer. Where else will you get this? Where else will you get overhanging or undermined edges? In any ulcer which involves more destruction of the subcutaneous tissue rather than the skin, so the skin is not destroyed, the subcutaneous tissue is getting destroyed. So you'll get in something like pyoderma gangrenosum, in rheumatoid disease, SLE. Ao autoimmune diseases, where you have the infection going under the subcutaneous plane. So if you get a history of these raised and rolled, they would never ask you anything apart from BCC. It’s always classical BCC.

01:30 You don't even have to think. Raised and rolled, go for BCC, nothing else. No, nothing else. And raised and everted, SCC, nothing else.

01:38 In the exam if you are getting a history along these lines, go for venous.
