  −
[[Sarcoid - Donkey|Sarcoid]] transformation at wound sites is a very common (and increasingly important) reason
  −
for wound healing failure. Sarcoid fibroblasts are a strong inhibitor of wound healing and the extent
  −
of the sarcoid within the wound/granulation tissue needs not to be high for inhibition to occur. The
  −
extent of the transformation is sometimes very limited but the effects remain profound. Healing
  −
is inhibited until all tumour cells are removed.
  −
 
  −
Confirmation of the problem is not always easy. Multiple biopsies from different parts of the tissue should be taken to ensure the maximum chance of finding it.
  −
 
  −
Special precautions such as early dressing application and particularly
  −
control of fly contact should be taken to protect wounds on donkeys that
  −
already have sarcoids at other sites. Wounds that involve sarcoid tissue
  −
are extremely dangerous because they are very difficult and sometimes
  −
impossible to treat.
