Quote from Turtle in scrubs
Wouldn't it have to be a stage 3 or 4 to have granulation tissue? Doesn't Stage 2 heal by epithelial proliferation and migration? Perhaps it would be better to say granulation tissue is only seen in full thickness wounds versus partial thickness wounds, because you have granulation tissue in wounds other than pressure ulcers. Does this sound correct?
This is correct. By definition, partial thickness ulcers still have intact dermis and basement membrane, which allows the keratinocytes to re-stratify to form the 4 (or 5 depending in location) epidermal layers. In full thickness wounds, collagen is deposited to fill the defect and new blood vessels form (angiogenesis). This gives rise to the so called beefy red appearance of granulation tissue, which by definition would only be present in full thickness ulcers. Hope that helps!
