Abstract: | OBJECTIVE: To present a case of chronic intractable leg ulceration caused by cholesterol crystal embolism. CLINICAL FEATURES: A 76-year-old Caucasian male with a history of ischaemic heart disease had repeated hospital admissions for diagnosis and treatment of recurrent leg ulceration of more than three years' duration. INTERVENTION AND OUTCOME: Definitive diagnosis was made after the third biopsy when the specimen obtained included subcutaneous arteries. Complete healing occurred within three weeks of excision and a skin graft, and subsequent treatment which included systemic steroids. CONCLUSION: Cholesterol crystal embolism is probably an underdiagnosed cause of intractable leg ulceration and can be identified by a biopsy specimen which includes vessels in subcutaneous fat. Systemic steroids may be helpful in its treatment. |
