Treatment of an atypical leg ulcer: pyoderma gangrenosum.

Mrs B was referred to the Skin and Woundcare Department at the start of January 2002 with a chronic non-healing ulcer to her lower right leg proximal to the medial aspect of her right knee. The ulcer was diagnosed as pyoderma gangrenosum, a condition which Mrs B had suffered from previously. Assessment and management of this atypical ulcer are discussed. Once the progression of the lesion was halted, conservative treatment could be undertaken, and led to a successful outcome.
