Background: Although there are numerous publications on multiple myeloma in black people, it seems sub- Saharan literature particularly Senegalese’ one is silent about Light chain deposition disease (LCDD) which is linked to immunoglobulin light chain deposition in glomerulus. The authors report the first three observations of LCDD collected in Nephrology department of Aristide Le Dantec hospital in Dakar, Senegal.
Cases: we report three cases a man and two women of 61, 69 and 47 years old respectively, admitted to the Nephrology department of Aristide Le Dantec hospital for rapidly progressive renal failure in one case and a nephrotic syndrome in 2 other cases. The renal biopsy showed a nodular glomerulosclerosis and immunofluorescence microscopy, revealed deposition of IgG light chains suggesting LCDD. On the other hand, the diagnosis of multiple myeloma of IgG kappa type in 2 cases and IgG lambda type in the other one was done. A combination of chemotherapy (Mephalan Prednisone) and hemodialysis was instituted for all 3 cases. The evolution was marked by the appearance of an end stage renal disease in 2 cases and the third one was expired due to an infected bed sore secondary to a pathological fracture of the neck of the femur.
Conclusion: Although the LCDD is rare, the prognosis of this syndrome seems to be poor as more than half of the patients die or progress to ESRD within 2 years.
