INFLAMMATORY RINGWORM DUE TO TRICHOPHYTON FAVIFORME

Abstract

INASMUCH as most mycologic studies are carried out in urban areas, it seems possible that the incidence of infections due to the various species of dermatophytes may differ in rural practice and, indeed, may vary with the section of the country studied. Ringworm in rural areas is usually of animal origin, inflammatory on the smooth skin and kerion-like in the beard and scalp. Fowle and Georg¹ in 1947 reported 14 cases of suppurative ringworm due to the faviform trichophyton, and it now seems apparent that this organism may assume considerable importance as a cause of ringworm of animal origin. Until 1942 it had been isolated but once in the United States, that instance being in the case reported by Gammel and Work² in 1938. Most reports point to Microsporum felineum (lanosum) as the organism most commonly causing inflammatory ringworm, with Microsporum gypseum (fulvum) reported less commonly.³ Among
