Nail dystrophy and blisters as sole manifestations in myeloma-associated amyloidosis.J Am Acad Dermatol. 2006 Apr; 54(4):712-4.JA
We report the case of a 61-year-old Japanese man with IgG lambda-type multiple myeloma, who presented with nail dystrophy as the initial manifestation of systemic amyloidosis. Subsequently he developed bullous amyloidosis. This report documents these two rare signs of systemic amyloidosis and demonstrates the precise location of cutaneous blister formation and amyloid deposition by fluorescence antigen mapping and electron microscopy.
