In this case we presented a case, who applied to our clinic with severe dermatosis and hematuria. We diagnosed high grade non-muscle invasive bladder tumor, which was treated with transurethral resection of bladder-tumor and six cycle of Bacillus Calmette-Guérin therapy. After the treatment the dermatosis was regressed almost completely. However, recurrent bladder tumor was detected at the first control cystoscopy.
