    Malassezia skin diseases in humans.
    G Ital Dermatol Venereol 2013 Dec;148(6):609-19
    Division of Dermatology Department of Surgery and Translational Medicine University of Florence, Florence, Italy -
    Although Malassezia yeasts are a part of the normal microflora, under certain conditions they can cause superficial skin infection, such as pityriasis versicolor (PV) and Malassezia folliculitis. Moreover the yeasts of the genus Malassezia have been associated with seborrheic dermatitis and dandruff, atopic dermatitis, psoriasis, and, less commonly, with confluent and reticulated papillomatosis, onychomycosis, and transient acantholytic dermatosis. The study of the clinical role of Malassezia species has been surrounded by controversy due to the relative difficulty in isolation, cultivation, and identification. Read More

    Three Cases of Concomitant Acanthosis Nigricans with Confluent and Reticulated Papillomatosis in Obese Patients.
    Ann Dermatol 2008 Jun 30;20(2):94-7. Epub 2008 Jun 30.
    Department of Dermatology, College of Medicine, The Catholic University of Korea, Seoul, Korea.
    Acanthosis nigricans (AN) is characterized by symmetric, velvety, gray-brown hypertrophied plaques most commonly on the axillae and neck. Confluent and reticulated papillomatosis (CRP) is manifested by papules in the mid-chest that coalesce in the midline, and are arranged in a reticulated pattern peripherally. Both diseases are known to be related to endocrinopathies such as diabetes mellitus (DM), an insulin resistant state and obesity with unknown mechanisms. Read More

    Dietzia papillomatosis sp. nov., a novel actinomycete isolated from the skin of an immunocompetent patient with confluent and reticulated papillomatosis.
