An 81-year-old woman presented with purpura, petechiae, ecchymoses, flesh or brown-colored waxy, smooth, papules, warty plaque, nail dystrophy and palmodigital erythematous swelling for more than 6 years. She was diagnosed as multiple myeloma-associated systemic amyloidosis after skin subcutaneous histopathological examinations and relevant examinations such as blood and bone marrow. Systemic amyloidosis is closely related with multiple myeloma (MM). Multiple and pleomorphic skin lesions are not usual among patients with multiple myeloma or systemic amyloidosis.
