Case 5

What is the name for the skin condition?

Pyoderma gangrenosum

What medications may be responsible?

Hydroxyurea contributed to slow healing

What management would you recommend?

The lower leg ulceration in this patient was diagnosed as pyoderma gangrenosum in association with myelodysplasia. It was extremely painful and failed to improve with systemic steroids and other therapies. The patient was on hydroxyurea, which is well known to cause leg ulceration, possibly related to microtrauma in anoxic, atrophic skin. When the hydroxyurea was discontinued, the ulcer steadily healed. Leg ulcers are sometimes also due to vasculitis, which also may be drug-induced.
