A Rare Case of Phaeohyphomycosis Caused by Exophiala Jeanselmei.

An outbreak of black piedra affected 60% of inmates of a women's hostel. One of the inmates who had piedra even before joining the hostel appears to be the source of infection. Use a common comb for dressing the hair and sharing of pillows and bed sheets while sleeping were the probable factors for spread of the disease. An indigenous treatment that consisted of daily exposure of the affected hairs to steam for 20 minutes was found to be beneficial.
