    Department of Experimental and Clinical Medicine, Institute of Dermatology, University of Udine, Udine, Italy.
    Over the last few years, dermoscopy has been shown to be a useful tool in assisting the noninvasive diagnosis of various general dermatological disorders. In this article, we sought to provide an up-to-date practical overview on the use of dermoscopy in general dermatology by analysing the dermoscopic differential diagnosis of relatively common dermatological disorders grouped according to their clinical presentation, i.e. Read More

    The practical usefulness of dermoscopy in general dermatology.
    G Ital Dermatol Venereol 2015 Oct 18;150(5):533-46. Epub 2015 Jun 18.
    Department of Experimental and Clinical Medicine Institute of Dermatology University of Udine, Udine, Italy -
    Beside to traditional use, dermoscopy is more and more used in the assessment of other "general" dermatologic conditions, namely scalp and hair disorders (trichoscopy), nails abnormalities (onychoscopy), skin infections and infestations (entomodermoscopy), and cutaneous inflammatory diseases (inflammoscopy). Among the list of new applications of dermoscopy, the study of inflammatory dermatoses is probably the most promising topic in terms of development and usefulness, considering the large number of such disorders and the frequent problems in their differential diagnosis which the dermatologist encounters in own daily clinical practice. In this paper, we report selected relatively common clinical differential diagnosis issues concerning inflammatory dermatoses (and some clinically related noninflammatory conditions), analysing them by a dermoscopic point of view in order to assist their noninvasive resolution according to the available literature data and our personal experience, including papulosquamous dermatoses (guttate psoriasis, pityriasis lichenoides chronica, pityriasis rosea, lichen planus, lymphomatoid papulosis, classic pityriasis rubra pilaris, papulosquamous sarcoidosis, disseminated forms of porokeratosis and papulosquamous chronic GVHD), dermatoses presenting with erythematous-desquamative patches/plaques (plaque psoriasis, eczematous dermatitis, pityriasis rosea, mycosis fungoides, subacute cutaneous lupus erythematosus), palmar psoriasis vs. Read More

    A case of perforating folliculitis in association with antisynthetase syndrome.
    J Biol Regul Homeost Agents 2015 Jan-Mar;29(1 Suppl):95-8
    ”Onkoderma”-Clinic for Dermatology and Dermatologic Surgery, Sofia, Bulgaria.
    Perforating folliculitis (PF) describes the process by which altered dermal material is eliminated from the epidermis through a follicular unit resulting in keratotic, follicular papules that favor hair-bearing regions of the forearms, arms, buttocks, and thighs. Diabetes mellitus (DM) and chronic renal failure (CRF) are commonly associated with PF. The more general term, acquired perforating dermatosis, has been applied to PF as well as Kyrle’s disease and the non-inherited form of perforating collagenosis. Read More

    Klinik und Poliklinik für Dermatologie, Universitätsklinikum Benjamin Franklin, Hindenburgdamm, Berlin.
    Perforating disorders represent a heterogenous group of dermatoses characterized by transepithelial elimination of dermal structures. Primary perforating disorders should be distinguished from secondary perforating disorders in which perforation with transepithelial elimination is a rare component of a variety of dermatoses. The primary perforating disorders are hyperkeratosis follicularis et parafollicularis in cutem penetrans (Kyrle's disease), elastosis perforans serpiginosa and perforating folliculitis. Read More

    Fibronectin and the extracellular matrix in the perforating disorders of the skin.
    Am J Dermatopathol 1998 Apr;20(2):147-54
    Department of Pathology: University of South Florida Health Science Center, James A. Haley Veteran's Hospital, Tampa, USA.
    Despite detailed microscopic descriptions and clinical observation, little is known regarding the pathogenesis of the perforating disorders of skin, which have traditionally been subdivided into numerous microscopic entities associated with various clinical settings. An increasing body of evidence now suggests that the perforating disorders of skin are akin, and may constitute an expanded single pathologic entity. Each of the classic perforating disorders of skin, including elastosis perforans serpiginosa, perforating folliculitis, reactive perforating collagenosis, Kyrle's disease, and perforating disorder of uremia, have been shown to extrude collagen, elastin, and related extracellular matrix components through the epidermis.

    Ther Umsch 1995 Apr;52(4):230-5
    Dermatologische Klinik, Universitätsspital Zürich.
    Skin symptoms in renal disease occur in a series of rare inherited or acquired diseases affecting the kidneys as well as the skin (amyloidosis, vasculitis, angiokeratoma diffusum corporis Fabry) (table 1). Chronic renal failure, regardless of its origin, often causes important skin symptoms, such as pruritus, the typical complexion with elastosis seen in uremic patients, porphyria cutanea uremica, metastatic calcifications, skin necrosis due to uremic small arteries disease with medial calcification and intimal hyperplasia, perforating dermatoses, nail lesions and symptoms of the oral mucosa (table 2). The following article reviews the pathogenesis and the limited possibilities of treatment for skin symptoms in chronic renal failure. Read More

    Acquired perforating dermatosis. Evidence for combined transepidermal elimination of both collagen and elastic fibers.
    Arch Dermatol 1989 Aug;125(8):1074-8
    Department of Dermatology, University of Texas Medical School, Houston 77030.
    Patients with renal disease or diabetes mellitus often have an acquired perforating disease of the skin develop that is characterized by hyperkeratotic papules with transepidermal elimination of degenerated material, including collagen or elastic fibers. There is disagreement regarding the most appropriate name for this disease. The pathologic process has been identified by various authors as reactive perforating collagenosis, elastosis perforans serpiginosa, perforating folliculitis, or Kyrle's disease. Read More

    Painful papule of the ear: a follicular disorder.
    J Dermatol Surg Oncol 1987 Mar;13(3):270-4
    The etiology of painful papule of the external ear, chondrodermatitis nodularis chronica helicis, has been an enigma for over half a century. I reviewed 84 skin biopsy specimens from 82 patients with this histopathologic diagnosis and found evidence that the infundibular portion of the hair follicle is probably the primary cutaneous structure involved in this condition. This lesion appears to evolve from an acute, suppurative, granulomatous dermatitis into a later-fibrosing dermatitis having the clinical and histologic features of perforating folliculitis and prurigo nodularis.
