Two cases of chylous effusion.

This classification is artificial, unsatisfactory and based on unsound biochemical investigation. Gandin (1913) was the first person to question the possibility of such differentiation. Collecting all recorded cases in the literature, he found wide discrepancies and stated that but o. i per cent. of finely emulsified fat is necessary to produce a turbid fluid. He believes that all milky fluids are due to an admixture of chyle and rejects the terms chyliform and pseudo-chylous as unwarranted.
