26 Possible Causes for Hyperparakeratosis

  • Oral Candidiasis

    Histopathological examination of tissue sections stained with H and E reveals epithelial hyperplasia with hyperparakeratosis and candidal hyphae in parakeratin layer invading[doi.org] Microscopic examination of the lesions reveals a localized superficial inflammatory reaction, hyperparakeratosis and ulceration of the surface covered with a fibrinoid[slideshare.net] […] at some places and homogeneous white patches in the periphery Click here to view Figure 2: Low--power photomicrograph (H and E, 10) showing hyperplastic epithelium with hyperparakeratosis[doi.org]

  • White Sponge Nevus

    Histological examination showed intense acanthosis and hyperparakeratosis-induced epithelial hyperplasia.[ncbi.nlm.nih.gov] Microscopic analysis revealed oral mucosa comprised of hyperplastic stratified squamous epithelium with either hyperparakeratosis or lack of keratinization.[ncbi.nlm.nih.gov] Histological examination showed acanthosis, hyperparakeratosis, spongiosis and the presence of an eosinophilic condensation in the perinuclear region from the spinous layer[ascro.hr]

  • Benign Migratory Glossitis

    When biopsy is taken, the histopathologic appearance is quite similar to psoriasis: Hyperparakeratosis. Acanthosis. Subepithelial T lymphocyte inflammatory infiltrate.[en.wikipedia.org]

  • Foreign-Body Reaction

    Histopathology showed epidermal endophytic proliferations under a pronounced hyperparakeratosis.[ncbi.nlm.nih.gov]

  • Confluent and Reticulated Papillomatosis

    Histologic Features: The epidermis shows papillomatosis with hyperparakeratosis and often acanthosis.[dermpedia.org]

  • Lupus Erythematosus

    Histologic Features Low-power: hyperparakeratosis with interface mucositis and perivascular inflammation. High-power: interface mucositis 16.[slideshare.net]

  • Lingual Papillitis

    In the papulokeratotic variant, biopsy shows severe hyperparakeratosis and mild chronic inflammation .[dermnetnz.org] Neg for HSV, HPV, fungi Term Histologic features of type 3 transient lingual papillitis Definition Marker shaggy hyperparakeratosis w/ bacterial colonization; chronic lymphocytic[flashcardmachine.com] […] migrating areas of depapillation) are so striking, there is rarely any need for biopsy . [11] When biopsy is taken, the histopathologic appearance is quite similar to psoriasis: Hyperparakeratosis[readtiger.com]

  • Optic Papillitis

    In the papulokeratotic variant, biopsy shows severe hyperparakeratosis and mild chronic inflammation.[dermnetnz.org]

  • Keratoacanthoma

    Histopathology showed epidermal endophytic proliferations under a pronounced hyperparakeratosis.[dermatology.cdlib.org]

  • Hyperlipoproteinemia

    The histologic hallmark of the 'spine' lesion was a compact column of hyperparakeratotic cells (columnar hyperparakeratosis) continuous with a hypogranular layer, without[ncbi.nlm.nih.gov] However, three main questions are related to SK: differential diagnosis with porokeratosis on histologic examination (columnar hyperparakeratosis or hyperorthokeratosis alone[ncbi.nlm.nih.gov]
