Introduction: Poems syndrome is characterized by polyneuropathy, organomegaly, endocrinopathy, M-proteins, and skin lesions.
Case: We describe here a case in which the eruption of diffuse cutaneous angiomas in a woman with a history of bone plasmocytoma and progressive polyneuropathy helped physicians to diagnose Poems syndrome.
Discussion: Other manifestations of Poems syndrome in this patient included endocrine dysfunction (hypothyroidism, adrenal insufficiency, and hypogonadism), sclerotic bone lesions of the femoral shaft, ribs, and vertebral body, monoclonal gammopathy, and anasarca. Steroid treatment led to dramatic improvement of polyserositis and a generally good outcome, despite persistence of the cutaneous lesions. This case points out this unusual cutaneous manifestation associated with Poems syndrome.
