Demodex Folliculorum.—DE AMICIS (Ital. Soc. of Derm., Brit. Journ. of Derm., January, 1899, p. 42).
Although previously considered a harmless inhabitant of the skin, in this instance the parasites caused a café-au-lait discoloration of the lip and chin of a lady. The microsporon furfur was excluded by examination. The demodex was found in large numbers, as many as twenty-two in one preparation. Measures taken to remove the parasite caused disappearance of the pigmentation. Professor Maiocchi narrated two cases in which the demodex had caused discoloration.
