Superficial mycoses are fungal infections limited to the stratum corneum and its adnexal structures. The most frequent types are dermatophytoses or tineas. Tinea versicolor involves the skin in the form of hypochromic or hyperchromic plaques, and tinea nigra affects the skin of the palms with dark plaques. White piedra and black piedra are parasitic infections of scalp hairs in the form of concretions caused by fungal growth. Diagnosis of these mycoses is made from mycologic studies, direct examination, stains, and isolation, and identification of the fungi. Treatment includes systemic antifungals, topical antifungals, and keratolytics.

Superficial fungal infections.

Lancet 2004 Sep 25-Oct 1;364(9440):1173-82

Dermatology, UMDNJ-New Jersey Medical School, 185 South Orange Avenue, Newark, NJ 07103-2714, USA.

Superficial fungal infections arise from a pathogen that is restricted to the stratum corneum, with little or no tissue reaction. In this Seminar, three types of infection will be covered: tinea versicolor, piedra, and tinea nigra. Tinea versicolor is common worldwide and is caused by Malassezia spp, which are human saprophytes that sometimes switch from yeast to pathogenic mycelial form. Read More

Tinea corporis, tinea cruris, tinea nigra, and piedra.

Dermatol Clin 2003 Jul;21(3):395-400, v

Division of Dermatology, Department of Medicine, Sunnybrook and Women's College Health Science Center (Sunnybrook Site), University of Toronto, 2075 Bayview Avenue, Toronto, Ontario M4N 3M5, Canada.

Tinea infections are among the most common dermatologic conditions throughout the world. To avoid a misdiagnosis, identification of dermatophyte infections requires both a fungal culture on Sabouraud's agar media, and a light microscopic mycologic examination from skin scrapings. Topical antifungals may be sufficient for treatment of tinea corporis and cruris and tinea nigra, and the shaving of hair infected by piedra may also be beneficial. Read More

White piedra, black piedra, tinea versicolor, and tinea nigra: contribution to the diagnosis of superficial mycosis.

An Bras Dermatol 2017 May-Jun;92(3):413-416

Dermatology Clinic, Hospital da Irmandade da Santa Casa de Misericórdia de São Paulo - São Paulo (SP) Brazil.

Superficial mycoses are fungal infections restricted to the stratum corneum and to the hair shafts, with no penetration in the epidermis; they are: white piedra, black piedra, tinea versicolor, and tinea nigra. This study presents images of mycological tests performed in the laboratory, as well as exams performed at the authors office, in order to improve the dermatologist's knowledge about the diagnosis of these dermatoses, which are common in many countries.

Tinea versicolor in dark-skinned individuals.

Eisenhower Medical Center, Rancho Mirage, CA and Baylor College of Medicine, Houston, TX, USA.

In this article, we review the salient features of tinea versicolor and describe the epidemiology, clinical presentation, and histopathology of this mycosis in dark-skinned individuals. Tinea versicolor is caused by an overgrowth of the Malassezia genus. It manifests clinically as asymptomatic hypopigmented macules, hyperpigmented macules, or a combination of the two. Read More
