Photoletter to the editor: Scarring alopecia resulting from pyoderma gangrenosum of the scalp.

Pyoderma gangrenosum is an uncommon ulcerative cutaneous condition of uncertain aetiology. It is a disease that causes tissue to become necrotic, leading to deep ulcers. We report a case of pyoderma gangrenosum localized at the scalp, which is an unusual location. After 16 months of treatment with prednisolone 40 mg daily, methotrexate 15 mg weekly, ciprofloxacin 500 mg and honey dressing the indurated elevated ulcer margins flattened and the ulcer healed with scarring of the entire scalp.
