    Detection of Borrelia burgdorferi sensu stricto and Borrelia garinii DNAs in patient with Hyperkeratosis lenticularis perstans (Flegel disease).
    Folia Microbiol (Praha) 2016 Sep 15;61(5):359-63. Epub 2016 Jan 15.
    Biology Center, Institute of Parasitology CAS, České Budějovice, Czech Republic.
    Determination of the causative agent of erythema-like skin lesions in case of nonspecific superficial perivascular dermatitis was supported by histological examination and led to the latter diagnosis of Hyperkeratosis lenticularis perstans (Flegel disease) in patient. The presence of antibodies against Borrelia burgdorferi in patient serum was confirmed by a routine ELISA method and verified by Western blot technique. Skin biopsy and blood specimens were analyzed by PCR and multilocus sequence analysis (MLSA). Read More

    Department of Dermatology, Venereology & Leprosy, Mahatma Gandhi Institute of Medical Sciences (MGIMS), Sewagram, Wardha, Maharashtra, India - 442102.
    Hyperkeratosis lenticularis perstans also known as Flegel's disease is a keratinisation disorder characterized by small keratotic papules with horny scales. Most cases have been reported in Europe with age of presentation between 35 and 60 years. We report a case of a 25-year-old man, who presented with 1-5 mm multiple asymptomatic hyperkeratotic papules of 15 years duration on both legs and hand along with lichenified plaques with Koebner phenomenon in the axillary folds, anticubital and popliteal fossae.

    Department of Anatomic Pathology, Hospital El Bierzo, Spain.
    We present a case of hyperkeratosis lenticularis perstans (Flegel's disease) in a 71-year-old-woman. Apart from all the typical morphological features of the disease, we evidenced mounds of parakeratosis that contained neutrophils, alternating with other strata of the horny layers in which no infiltrate was seen. Such a pattern has been described in association with diseases that show a periodic clinical pattern of presentation with periods of exacerbations and remissions. Read More

    Department of Dermatology, and Maastricht University Center for Molecular Dermatology, University Medical Center Maastricht, The Netherlands.
    Flegel's disease, also known as hyperkeratosis lenticularis perstans, is a rare skin disease characterized by small, red-brown, hyperkeratotic, papules that are usually located on the lower extremities. The diagnosis is based on the clinical appearance in association with the typical histologic features of orthohyperkeratosis and a subepidermal band-like infiltrate. Treatment is difficult and rarely fully effective. Read More

    Department of Dermatology, Japanese Red Cross Nagoya First Hospital, Nagoya, Japan.
    A case of hyperkeratosis lenticularis perstans (Flegel's disease) was studied histopathologically comparing early and old lesions. The age of the lesions were judged by both the patient's history and direct observation. The histopathologic and immunophenotypic features of a new lesion were essentially in accordance with previous findings. Read More

Lesional and non-lesional epidermis samples were studied by light- and electron-microscopic examination. The main ultrastructural finding was the presence of structurally altered Odland bodies/membrane-coating granules. Read More

    Hyperkeratosis lenticularis perstans (Flegel's disease) is a rare but clinically and histologically highly characteristic genodermatosis. We report on new immunohistochemical and ultrastructural findings suggesting a complex disorder of epidermal differentiation. In this context, a good response to calcipotriol, a synthetic vitamin D3 derivative is of particular interest. Read More

    Department of Dermatology I, University of Vienna Medical School, Austria.
    Lesional and perilesional skin samples from a 57-year-old man who had hyperkeratosis lenticularis perstans (HLP) (Flegel's disease) were studied by light and electron microscopic examination. Keratohyalin granules were diminished at the center of a fully-developed lesion. In contrast, keratohyalin appeared normal and membrane-coating granules were found in reduced numbers at the edges of the HLP lesion and were easily detected in normal numbers in clinically normal, perilesional skin.

    We report a patient with hyperkeratosis lenticularis perstans (HLP) manifesting as multiple reddish-brown hyperkeratotic papules on the lower extremities. Typical histologic features of HLP include hyperkeratosis, thinning or absence of the granular layer and a band-like infiltrate in the upper dermis underlying an atrophic epidermis. In order to determine the cellular composition of the infiltrate, skin biopsy specimens were studied immunohistochemically using a series of commercially available monoclonal antibodies. Read More

    Lamellar bodies in hyperkeratosis lenticularis perstans.
    J Cutan Pathol 1987 Aug;14(4):207-11
    An ultrastructural study of lesional skin from 4 subjects with hyperkeratosis lenticularis perstans (Flegel's disease) demonstrated variable numbers of lamellar bodies of normal size and architecture within cells of the stratum granulosum and the upper stratum spinosum. Their characteristic lamellate inclusions were frequently observed within the intercellular spaces. These observations suggest that the lamellar bodies are qualitatively normal in Flegel's disease.

    A 62-year-old female with a 20-year history of small horny papules on the skin of the legs is described. Light microscopy revealed a hyperkeratotic papule with atrophic epidermis and a dense dermal inflammatory cell infiltrate with many cerebriform lymphocytes not earlier described in connection with hyperkeratosis lenticularis perstans (HLP). The electron-microscopic picture showed membrane-coating granules (MCG) and keratohyalin located in different cells, indicating that the disorder of keratinization in HLP is possibly caused by reduced co-operation between these cells and that the keratinization process occurs in the absence of MCG.

    The dyskeratotic changes in the lesions of hyperkeratosis lenticularis perstans were examined electron microscopically and histochemically. Under electron microscopy, the formation of keratohyalin granules was reduced and there was a lack of lamellar granule formation. In addition, the catabolic processes were disturbed, and ribosomal and mitochondrial structures remained, and lipid crystal-like structures were seen in the stratum corneum. Read More

    2 patients with typical clinical and histological pictures of hyperkeratosis lenticularis perstans were described. Both patients showed abnormalities of the mucosal surface.
