Abstract |
White piedra is a fungal infection of the hair shaft caused by Trichosporon beigelii. A synergistic coryneform bacterial infection is often present with T beigelii. White piedra, although not commonly reported to infect scalp hair in North America, is an important consideration in the differential diagnosis of scalp hair concretions. We report a case of white piedra of scalp hair with synergistic coryneform bacterial infection in two sisters, both US natives. Culture and light and electronmicroscopic evidence of the synergistic infection are presented.
