Summary
Cholesterol crystal embolism is an underdiagnosed cause of chronic leg ulcers. Biopsy of subcutaneous arteries aids diagnosis, and treatment may involve systemic steroids for healing.
Area of Science:
- Vascular Medicine
- Dermatology
- Pathology
Background:
- Chronic leg ulceration presents a significant clinical challenge, often with unclear etiology.
- Atherosclerotic disease is common in elderly patients, predisposing to embolic phenomena.
Observation:
- A 76-year-old male with ischemic heart disease experienced prolonged, recurrent leg ulceration.
- Previous treatments were ineffective, highlighting the need for an accurate diagnosis.
Findings:
- Definitive diagnosis of cholesterol crystal embolism was achieved via biopsy of subcutaneous arteries.
- Surgical intervention (excision and skin graft) combined with systemic steroids resulted in complete ulcer healing within three weeks.
Implications:
- Cholesterol crystal embolism should be considered in cases of intractable leg ulceration.
- Histopathological examination of subcutaneous vessels is crucial for diagnosis.
- Systemic steroid therapy may be a valuable adjunct in managing this condition.
