Cases of white piedra of the hair on the American continent: a case report and a systematic literature review
Abstract
White piedra of the hair is a rare superficial fungal infection caused by several Trichosporon spp.1 It typically manifests as white to light brown hard nodules, firmly attached to frontal, occipital, and parietal scalp hair.1-9 The incidence of white piedra varies from country to country, and men and women of all ages are affected.1 In Latin America, children and women appear to be the most affected with white piedra of the hair.1-9 Given the variability of causative agents and the paucity of literature, very little is known about the geographical distribution of white piedra of the hair in American continent countries to help understand its epidemiology and aid in its diagnosis and treatment. In this report, we describe a case of white piedra of the hair in a Peruvian woman. We also conducted a systematic literature review of all case reports of white piedra on the American continent, with a view to determining the geographical distribution of the condition and identifying Trichosporon spp. commonly associated with this infection.

How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
