A rare form of plasma cell dyscrasia characterized by associated polyneuropathy, organomegaly, endocrinopathy, M protein and skin changes has been termed the POEMS syndrome. The pathophysiology is unknown; plasma cell dyscrasia is essential; secondary manifestations are unexplained. We report a 67-year-old man with a 7-month history of progressive weakness and numbness of the legs. Clinical examination revealed sensorimotor polyneuropathy, predominantly affecting the lower extremities, hepatomegaly, and skin haemangiomas. Additional investigations disclosed IgG-lambda monoclonal serum protein, endocrine abnormalities, elevated cerebrospinal fluid protein level and an osteoblastic lesion of the lumbar vertebra. Biopsy of the osteosclerotic vertebra showed a marked lymphoplasmocytic infiltrate. MRI of the liver disclosed two haemangiomas; this association has not been reported previously.
