| Abstract: | Mucocutaneous lesion appears in up to 40% of patients with primary systemic amyloidosis (AL amyloidosis). The cutaneous signs may be co-expressed with other organ involvement or even solely presented as the first clue. We reported a case of systemic AL amyloidosis who was initially presented as a solitary hemangioma with a purpuric halo. Excisional biopsy revealed a hemangioma with amyloid deposited in thickened vascular walls. Systemic AL amyloidosis was diagnosed after thorough survey. The stage of disease at the time of initial treatment is the greatest prognostic factor. To our knowledge, this is the first case of systemic AL amyloidosis initially presented as a purpuric halo around hemangioma in Taiwan. This target-like lesion should be linked to systemic AL amyloidosis and early diagnosis is extraordinary important. |
