title: Fixed sporotrichosis as a cause of a chronic ulcer on the knee.
abstract: Chronic wounds are a major health care problem worldwide. Wound healing is a holistic endeavour that requires an accurate identification of the specific entities interfering with wound healing in a particular patient. We present a case of fixed sporotrichosis as the cause of a chronic ulcer in the knee. Although a culture of Sporothrix schenckii could not be obtained, a positive response to the sporotrichin skin test, a skin biopsy showed a suppurative granuloma and an adequate response to oral administration of potassium iodide confirmed the diagnosis. The identification and correction of the underlying aetiology of any chronic wound is the first and most important step to restore wound healing.
