In October, 1920, Frederick S. Burns1 presented a study of xanthoma from the biochemical standpoint, in which he reached the conclusion that these interesting tumors are due to a high percentage of cholesterin in the blood and the subsequent deposit of cholesterin compounds in the tissues. His paper presented also a complete review of the literature, and his results were confirmatory of the work done by previous investigators.
The cases which we have studied in the past few years present also a uniformly high cholesterinemia, and we, therefore, put them on record. We present here the records of three cases of xanthoma diabeticorum and three cases of xanthoma tuberosum.
