Treatment of ulcerated necrobiosis lipoidica with ovine forestomach matrix

Abstract

Necrobiosis lipoidica (NL) results from degradation of the collagen extracellular matrix; these recurring ulcerated lesions are an especially challenging condition to treat. Ovine forestomach matrix (OFM) is a decellularised extracellular matrix and was used to successfully close a pretibial ulcer resulting from NL. Complete closure of the wound was achieved in 22 weeks, after four applications of OFM. This suggests OFM may be considered for the treatment of these challenging wounds.
