Distribution

           The geographic distribution of black piedra is limited to tropical and subtropical areas that have high temperatures and humidity,  for example : South and Central America and South-East Asia (Ann Dermatol Venereol, 1987). Black piedra have also been reported  in Africa and the South Pacific islands. Kaplan studied the infection in primate pelts. He found it in 57 out of 94 (60,6%) pelts from Asia; in 83 out of 109 (78,1%) from the New World; and in 58 out of 202 (28,7%) from Africa and only 2 cases were found in 33 primates in zoos in the United States (2).
