Diagnostic Considerations

Poikiloderma secondary to mycosis fungoides, dermatomyositis, and scleroderma should be included in the differential diagnoses. Poikiloderma-like cutaneous amyloidosis is characterized by poikiloderma-like skin changes, lichenoid papules, and blisters. Diagnosis is a challenge, and a skin biopsy is needed. Histologic finding of cutaneous amyloid deposits is diagnostic. [17]
