Serum immunofixation electrophoresis, computed tomography of the spine, external appearance of both feet, and sural nerve biopsy. a Serum immunofixation electrophoresis showing an IgGλ monoclonal gammopathy. b Computed tomography of the spine with contrast showing multiple mixed lytic osteosclerotic bone lesions involving the T8 and L1 bodies. c Localized hypertrichosis associated with hyperpigmentation involving the dorsal aspect of both feet. Sural nerve biopsy showing neuropathy through slightly decreased myelinated fibers density with mild to moderate increase of small vessels in epineurium (arrows) (d: Luxol Fast Blue staining, 100×) and positive VEGF staining (e: VEGF staining, 200×)
