    Folliculocentric tinea versicolor.
    Dermatol Online J 2017 02 15;23(2). Epub 2017 Feb 15.
    Department of Dermatology, Texas Tech University Health Sciences Center, Lubbock.
    Tinea versicolor (TV) is typically an asymptomatic fungal infection of the stratum corneum owing to Malassezia overgrowth. It presents as hypo or hyperpigmented macules with fine scale that coalesce into patches on the trunk, neck, and/or arms. Presented in this report is a 34-year-old man with an interesting case of folliculocentric tinea versicolor manifesting as perifollicular hypopigmented macules on the lower back. Read More

    Confluent and Reticulated Papillomatosis With Linear Pseudo-striae: A Description of 20 Cases.
    Actas Dermosifiliogr 2017 Mar 2. Epub 2017 Mar 2.
    E.S.E Centro Dermatológico Federico Lleras Acosta, Bogotá D.C., Colombia; Fundación Universitaria Sanitas, Bogotá D.C., Colombia.
    Confluent and reticulated papillomatosis, also known as Gougerot-Carteaud Syndrome, is a rare chronic disease typically affecting young adults. Of unknown etiology, the condition is characterised by oval grayish-brown or erythematous papules that coalesce to form a reticular pattern, usually on the trunk, especially in the intermammary or interscapular region and on the neck. Diagnosis is primarily clinical, based on the appearance of the lesions, the areas affected, and the response to treatment with minocycline. Read More

    Atrophic pityriasis versicolor occurring in a patient with Sjögren's syndrome.
    BMJ Case Rep 2017 Jan 18;2017. Epub 2017 Jan 18.
    Unit of Dermatology, University of Padua, Padua, Italy.
    Pityriasis versicolor is one of the most frequent epidermal mycotic infections in the world, but its atrophic variant is rarely described. The aetiology of the atrophy is still unknown, and two main hypotheses have been formulated, one suggesting a correlation with long-term use of topical steroids and the other a delayed type hypersensitivity to epicutaneous antigens derived from components of the fungus. Atrophic pityriasis versicolor is a benign disease, but needs to be distinguished from other more severe skin diseases manifesting with cutaneous atrophy. Read More

    The evaluation of local oxidative/nitrosative stress in patients with pityriasis versicolor: a preliminary study.
    Mycoses 2016 Nov;59(11):720-725
    Department of Dermatology, Faculty of Medicine, Sutcu Imam University, Kahramanmaras, Turkey.
    Yeast of Malassezia, members of the microbiologic flora of the skin, cause pityriasis versicolor and have also been implicated in the pathogenesis of other superficial dermatoses. The mechanisms by which the yeast cause these dermatoses, however, are not yet clear, and there have been no studies on the interaction between fungi and keratinocytes, especially the effects of fungi on the production of reactive oxygen/nitrogen species by human keratinocytes. This is the first study we aimed to evaluate the role of oxidative/nitrosative stress in affected skin areas in patients with pityriasis versicolor. Read More

    Oral Antifungal Drugs in the Treatment of Dermatomycosis.
    Med Mycol J 2016 ;57(2):J71-5
    Department of Dermatology, Tokyo Women's Medical University.
    Oral antifungal drugs are used primarily to treat tinea unguium; however, they are also useful for other types of tinea. For example, a combination of topical and oral antifungal drugs is effective in hyperkeratotic tinea pedis that is unresponsive to topical monotherapy. In cases of tinea facialis adjacent to the eyes, ears, or mouth, or widespread tinea corporis, or tinea cruris involving the complex skin folds of the external genitalia, it is difficult to apply topical drugs to all the lesions; therefore, oral antifungal drugs are necessary.

    Malassezia Pneumonia: A Rare Complication of Parenteral Nutrition Therapy.
    JPEN J Parenter Enteral Nutr 2016 Nov 6;40(8):1194-1196. Epub 2015 Jul 6.
    Indiana University School of Medicine, Indianapolis, Indiana.
    Malassezia species (formerly known as Pityrosporum) are part of normal human skin flora and have been associated with benign dermatologic conditions, such as seborrheic dermatitis and tinea versicolor. In rare cases, however, Malassezia has been associated with systemic disease in immunocompromised patients and infants in the neonatal intensive care unit. Malassezia species require long-chain fatty acids for growth and therefore have a known predilection for individuals receiving lipid containing intravenous parenteral nutrition (PN). Read More
