This serves to break open the already inflammed skin, freeing the parasite to move on to its next stage. This can result in a parasitic nodule sitting under the skin, causing an inflammatory reaction. The skin is the body's largest organ and plays an important role in keeping the body healthy. The skin of all vertebrates serves to keep bodily fluids in the body, and keep bacteria, fungi, and parasitic organisms that don't belong in the body out of it. When a problem occurs in the skin, it is important that it be properly evaluated.
Epithelial cells start to move into the area under the scab, forming a thin layer.
As these cells increase in number, the layer thickens. While this is going on, macrophages and heterophils, the body's clean-up crew, move in under the scab layer and clean up bacteria and cellular debris. That is, over a period of time, they dissolve away and fall out. They do not always fall out, even though they may have dissolved under the epidermis. These stitches should be removed to prevent them getting caught on anything - or falling out and being ingested by the reptile, child or pet.
