    Cutaneous Manifestations of Diabetes Mellitus: A Review.
    Am J Clin Dermatol 2017 Apr 3. Epub 2017 Apr 3.
    Department of Dermatology, University Hospital Jena, Erfurter Straße 35, 07740, Jena, Germany.
    Diabetes mellitus is a widespread endocrine disease with severe impact on health systems worldwide. Increased serum glucose causes damage to a wide range of cell types, including endothelial cells, neurons, and renal cells, but also keratinocytes and fibroblasts. Skin disorders can be found in about one third of all people with diabetes and frequently occur before the diagnosis, thus playing an important role in the initial recognition of underlying disease.

    Borderline Tuberculoid Leprosy Masquerading as Granuloma Annulare: A Clinical and Histological Pitfall.
    Am J Dermatopathol 2017 Apr;39(4):296-299
    *Keck School of Medicine, University of Southern California, Los Angeles, CA; andDepartments of †Dermatology, and‡Pathology and Laboratory Medicine, University of California Davis School of Medicine, Sacramento, CA.
    Introduction: Leprosy is a chronic granulomatous disease caused by Mycobacterium leprae, an intracellular acid-fast bacillus that tends to infect the skin and peripheral nerves. Because of the wide array of cutaneous manifestation, diagnosis is not always straightforward, especially in nonendemic regions of the world such as the United States.

    Case Report: The authors report an unusual case of borderline tuberculoid leprosy in an 80-year-old white woman from California. Read More

    What is new in the histogenesis of granulomatous skin diseases?
    J Dermatol 2017 Mar;44(3):297-303
    Department of Dermatology, Kyoto prefectural University of Medicine, Graduate School of Medical Science, Kyoto, Japan.
    A granuloma is a form of inflammation, which predominantly consists of macrophages. It typically develops when the immune system attempts to enclose substances that are usually insoluble and cannot be eliminated to prevent the spread of these substances to the other body compartments. According to the source of the substances, granulomatous diseases can be divided into two groups: infectious and non-infectious. Read More

    Actinic Granuloma Annulare With Scarring and Open Comedones.
    Am J Dermatopathol 2017 Feb 14. Epub 2017 Feb 14.
    *Department of Dermatology, Medical School, University of São Paulo, São Paulo, Brazil; and †Department of Pathology, Hospital Obrero, La Paz, Bolivia.
    Actinic granuloma and annular elastolytic giant cell granuloma are variants of granuloma annulare affecting, respectively, sun-exposed and sun-covered skin sites on where, besides classical findings, abundant elastophagocytosis is observed. Here, we report a case of exuberant actinic granuloma annulare that, in addition to extensive scarring, showed multiple overlying open comedones. Markedly dilated follicular infundibula filled with compact masses of laminated keratinous material were observed in proximity to dermal inflammation composed of many histiocytes and multinucleated giant cells in close association with degenerated elastic fibers and abundant elastophagocytosis.

    Several dermatoses are routinely associated with diabetes mellitus, especially in patients with chronic disease. This relationship can be easily proven in some skin disorders, but it is not so clear in others. Dermatoses such necrobiosis lipoidica, granuloma annulare, acanthosis nigricans and others are discussed in this text, with an emphasis on proven link with the diabetes or not, disease identification and treatment strategy used to control those dermatoses and diabetes.

    Granulomatous & histiocytic dermatitides.
    Semin Diagn Pathol 2017 May 14;34(3):301-311. Epub 2016 Dec 14.
    Section of Dermatopathology, Division of Surgical & Cytological Pathology, University of Virginia Medical Center, Charlottesville, VA, USA. Electronic address:
    Granulomas of the skin may be classified in several ways. They are either infectious or non-infectious in character, and they contain areas of necrobiosis or necrosis, or not. Responsible infectious agents may be mycobacterial, fungal, treponemal, or parasitic organisms, and each case of granulomatous dermatitis should be assessed histochemically for those microbes.

    [Two children with intermediate uveitis and granuloma annulare from the same neighbourhood].
    Ophthalmologe 2017 Jan 9. Epub 2017 Jan 9.
    Universitäts-Augenklinik Tübingen, Eberhard Karls Universität Tübingen, Elfriede-Aulhorn-Straße 7, 72076, Tübingen, Deutschland.
    Two children from the same neighbourhood presented with concomitant granuloma annulare (GA) and intermediate uveitis (IU) at an interval of 2 weeks. A coincidence seemed unlikely, as IU is very rare in children and even more so in connection with GA. Thorough diagnosis was performed to exclude other associated diseases. Read More

    Palisaded Granuloma on the Nose: An Atypical Presentation of Granuloma Annulare.
    Am J Dermatopathol 2017 Feb;39(2):e26-e28
    *Department of Dermatology, School of Medicine, University of Puerto Rico, San Juan, PR; and †Department of Dermatology, University of Puerto Rico, San Juan, PR.
    Granuloma annulare (GA) is a common, asymptomatic dermatosis of unknown etiology. Many variants exist, among them widespread papules, papules in photodistribution, papules marked by tiny crusts ("perforating" GA), patches, plaques, and nodules (subcutaneous GA). The histopathological hallmark is a palisaded histiocytic infiltrate surrounding a central area of degenerated collagen with abundant mucin deposits. Read More

    IRCCS, AOU. San Martino-IST, Di.S.Sal. Section of Dermatology, University of Genoa, Genoa, Italy.
    Granuloma annulare (GA) is a chronic, benign, and usually self-limiting cutaneous inflammatory disease, typically characterized by small, localized, skin-coloured papules that are usually asymptomatic or mildly pruriginous. Its aetiopathogenesis is still unknown and treatments are rarely effective. Generally, 50-70% of localized GA cases are self-limiting and show spontaneous resolution after 1-2 years, whereas disseminated GA is less likely to disappear without treatment. Read More

Very rarely it can present on the face and rarer still on periorbital structures such as the eyelid and orbital rim. Diagnosis hinges on clinical presentation and histological features, such as palisading granulomas with central destruction of collagen, presence of mucin and lymphohistiocytic infiltration.
