Permanent improvement of renal dysfunction and proteinuria with colchicine in a patient with tumoral amyloidosis and basal cell carcinoma.

Basal cell carcinoma and amyloid deposition was reported not uncommonly, but renal failure and nephrotic syndrome were rare. Here in, we reported a 72 years old male patient with nephrotic syndrome, renal failure and relatively small basal cell carcinoma. In this patient toumoral excision caused temporary improvement. When the proteinuria reappeared, due to amyloid deposition in toumoral tissue, colchicine was began. With colchicine therapy permanent improvement of nephrotic syndrome was achieved in follow-up 18 months.
