I searched The Cochrane Library (from 1991 to October, 2002) and MEDLINE (from 1966 to present) with the terms “Malassezia”, “tinea versicolor”, “piedra”, and “tinea nigra”. I translated or had translated all relevant non-English articles from this search. I largely selected articles from the past decade, showing a preference for the most recent ones, but did not exclude older contributions of significant value. I also searched the journals Mikologia Lekarska (Wroclaw), Cesko-Slovenská

Epidemiology
Tinea versicolor, also known as pityriasis versicolor, is one of the most common pigmentary disorders worldwide.1, 2, 3 It is frequently seen in tropical regions, with prevalence as high as 40%; it is also common in temperate areas, representing up to 3% of patients seen by dermatologists during the summer months.2, 4 The infection can arise at any age, with most cases occurring during adolescence and young adulthood.2 Hormonal changes or increases in sebum secretion might be relevant. In one
Epidemiology
Piedra, which means stone in Spanish, is an asymptomatic fungal infection of the hair shaft;91, 92, 93, 94, 95, 96 it is also known as trichomycosis nodularis. Both sexes and people of all ages are equally affected.97 Under-reporting of cases could happen because nodules of piedra can be inconspicuous.98
In 1911, Horta99 classified piedra into two types: black piedra and white piedra (trichosporosis).97, 98, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115 The two
Epidemiology
Tinea nigra is common in tropical regions of Central America, South America, Africa, and Asia, and is infrequent in the USA and Europe.116, 117, 118 In the USA, it typically affects coastal states such as Florida, Texas, Alabama, Louisiana, Virginia, Georgia, and North Carolina. Although cases of tinea nigra are also seen in patients from northern and inland regions of the USA, including New York City, Chicago, and Boston, such patients typically have a history of foreign travel, frequently to

This chronic infection can be misdiagnosed as malignant melanoma or a junctional melanocytic nevus and unnecessary biopsies may be performed [4]. Thus, dermoscopy can be used to distinguish tinea nigra from melanocytic lesions.
