301 Possible Causes for Follicular Plugging

  • Discoid Lupus Erythematosus

    Histopathology showed epidermal atrophy, hyperkeratosis, follicular plugging, thickening of the basement membrane zone, and superficial and deep chronic perivascular and periadnexal[] Lupus erythematodes tumidus is characterized by smooth, erythematous plaques on sun-exposed areas without surface changes, such as follicular plugs, atrophy, or scale.[] plugging, dyspigmentation, atrophy, and scarring.[]

  • Keratosis Pilaris

    Erythromelanosis follicularis faciei et colli (EFF) is an unusual condition characterized by the triad of hyperpigmentation, follicular plugging and erythema of face and neck[] Histological examination revealed abundant mucin, keratotic follicular plugging, and periadnexal lymphocytosis.[] Histologic examination showed follicular and interfollicular hyperkeratosis, follicular plugging, mild inflammation, and focal scarring.[]

  • Vitamin A Deficiency

    ) secondary to blockage of hair follicles with plugs of keratin.[] Poor adaptation to darkness (nyctalopia) Dry skin Dry hair Pruritus Broken fingernails Keratomalacia Xerophthalmia Corneal perforation Follicular hyperkeratosis (phrynoderma[]

  • Pityriasis Rubra Pilaris

    Microscopically follicular plugging, in addition to checkerboard alternating orthokeratosis/parakeratosis, may serve as clues to PRP diagnosis.[] Histological picture combined pemphigus-like acantholysis with alternating hyper- and parakeratosis, follicular plugs and dermal inflammation, and confirmed the clinical diagnosis[] The skin biopsy showed acanthosis, alternating orthokeratosis, parakeratosis, and follicular plugging suggestive of pityriasis rubra pilaris.[]

  • Folliculotropic Mycosis Fungoides

    A 40-year-old man presented with pruritic plaques affecting his head and trunk, characterized by follicular plugging.[] RESULTS: Male and older age group predominance, frequent head-neck involvement, acneiform lesions, keratotic plugs, cysts, nodules, follicular papules, alopecia and classic[] A, Large patch of alopecia with follicular plugging. B, Loss of the left eyebrow and eyelashes. C, Widespread psoriasiform plaques.[]

  • Acne Vulgaris

    Several factors are involved in the pathogenesis of the disease including abnormal sebum production, altered follicular keratinization with subsequent follicular plugging[] "Blackheads" (open comedones) and "whiteheads" (closed comedones) are follicular plugs that are either sitting below the skin surface (whitehead) or oxidized from being exposed[]

  • Demodicosis

    Demodectic mites produce histologically observable tissue and inflammatory changes, epithelial hyperplasia, and follicular plugging.[] Under the dermoscopy, the papule was semisphere with tawny follicular plug inside. c. Under SEM, rod-shaped bacteria were closely spaced in follicular plug tissue. 3.9.[] Although epithelial hyperplasia associated with follicular plugging is often encountered, dermal changes seldom extend beyond the perifollicular epidermal area.[]

  • Chilblain Lupus Erythematosus

    Histopathologically forearm lesion revealed mild hyperkeratosis, mild atrophy, irregular acanthosis, follicular plugging, extensive vacuolar degeneration and patchy perivascular[] The depigmented skin over the fingers had mild erythema but there was no scaling or follicular plugging in any of the lesions. The lips were not depigmented.[] Initially small erythematous follicular papules may be observed, with little scaling stuffing the in-fundibula and progressing to form follicular horny plugs.[]

  • Atrophodermia Vermiculata

    The primary pathologic event seems to be the formation of follicular plugs.[] Atrophodermia vermiculata is characterized by erythema and follicular plugs on the cheeks, developing into painless reticular impressions.[] Erythema and pinhead follicular plugs developing mainly on the cheeks are soon followed by asymptomatic, sharply demarcated, pit-like or net-like impressions.[]

  • Pseudopelade of Brocq

    The histopathology is characteristic, and shows the following features: little or only moderate lymphocytic infiltrate, absence of significant follicular plugging, and absence[]
