    Acquired perforating dermatosis in a patient with chronic renal failure.
    An Bras Dermatol 2016 Sep-Oct;91(5 suppl 1):10-13
    Universidade Federal do Estado do Rio de Janeiro (UNIRIO) - Rio de Janeiro (RJ), Brazil.
    Perforating dermatoses are a group of skin diseases characterized by transepidermal elimination of dermal material. The disease is divided into two groups: the primary group and the secondary group. The classical or primary perforating dermatoses are subdivided into four types according to the eliminated dermal materials: Kyrle disease, perforating reactive collagenosis, elastosis perforans serpiginosa, and perforating folliculitis.

    Background: Reactive perforating collagenosis (RPC) belongs to the group of perforating dermatoses, which comprises elastosis perforans serpiginosa, RPC, perforating folliculitis and Kyrle's disease. RPC was initially described as a distinctive form of transepithelial elimination of altered collagen related to superficial trauma. Two types are distinguished: a hereditary type (MIM 216700), which is rare and begins during early childhood, and a second type, called acquired RPC, which is more frequent, appears in adults and is associated with other diseases, diabetes mellitus, renal insufficiency, solid tumors, lymphomas and AIDS.

    Kyrle disease and acquired perforating collagenosis secondary to chronic renal failure and diabetes mellitus.
    Case Rep Dermatol 2011 Sep 29;3(3):209-11. Epub 2011 Sep 29.
    Department of Dermatology, University Hospital Regensburg, Regensburg.
    A 59-year-old man with chronic renal failure and diabetes mellitus presented with pruritic crusted lesions which histologically were perforating disorders, showing features of both Kyrle disease and acquired perforating collagenosis. The mechanisms of transepidermal elimination and the classification of perforating disorders are briefly discussed. Additionally, we question the concept of perforation, as epidermal damage and exposure of subepidermal substances may artificially present as perforation. Read More

    Acquired reactive perforating collagenosis: current status.
    J Dermatol 2010 Jul;37(7):585-92
    Department of Dermatology, Faculty of Medicine, Democritus University of Thrace, Alexandroupolis, Greece.
    Acquired reactive perforating collagenosis is a unique perforating dermatosis, characterized clinically by umbilicated hyperkeratotic papules or nodules and histologically by a focal hyperkeratosis in direct contact with transepidermal perforating dermal collagen. Several inflammatory or malignant systemic diseases may coexist with acquired reactive perforating collagenosis. The possible biochemical or immunological mechanisms of the systemic diseases, potentially responsible for the development and appearance of acquired reactive perforating collagenosis, are still under investigation.

    Allopurinol in dermatology.
    Am J Clin Dermatol 2010 ;11(4):225-32
    Department of Dermatology, National Taiwan University Hospital, Taipei, Taiwan.
    Off-label use is common in dermatology, and is inevitable for rare cutaneous diseases such as perforating dermatosis. Allopurinol is traditionally considered to be a drug for hyperuricemia only, but the recent demonstration of its efficacy in congestive heart failure has spurred renewed interest in its application in other clinical specialties. In dermatology, allopurinol is best known for its severe cutaneous adverse reactions. Read More
