169 Possible Causes for Elongation of Rete Ridges

  • Penile Intraepithelial Neoplasia

    Elongation of rete ridges with bridging/anastomoses between rete ridges. Nuclear atypia - esp. of the basal layer. Nuclei in stratum corneum ( parakeratosis ).[librepathology.org] Image C Image D Histology: Differentiated PEIN (HPV-unrelated): elongated rete ridges with abnormal maturation (pinker cytoplasm); whorling and keratin earl formation.[auanet.org] Histopathological examination demonstrates hyperkeratosis, parakeratosis, acanthosis, elongated rete ridges, and mild lower epidermal dysplasia with a nonspecific dermal inflammatory[ijstd.org]

  • Dyschromatosis Universalis Hereditaria 1

    Skin biopsy from the hypopigmented macule over the lower abdomen also showed elongation of the rete ridges but with pigmentation limited only to the tips of the rete pegs[omicsonline.org] .  Epidermal atrophy  Elongated thin rete ridges  Increased basal layer pigmentation at tips of rete ridges  Special staining shows increased number of dopa-positive melanocytes[slideshare.net] The acanthosis and elongation of rete ridges, though typical were much lesser in the hypopigmented macule compared to the hyperpigmented macule.[omicsonline.org]

  • Angiokeratoma Circumscriptum

    […] of rete ridges.[docksci.com] It interestingly showed features of hyperkeratosis, acanthosis and elongation of rete ridges, dilated and congested blood vessels in papillary dermis.[ijpmonline.org] (b and c) Epidermis showing hyperkeratosis and acanthosis with elongation of rete ridges.[ijpd.in]

  • Dowling-Degos Disease Type 1

    Figure 2: (a) Skin biopsy from the hyperpigmented macules showing hyperkeratosis, elongated and bifurcated rete ridges (‘antler like’ rete ridges) with increased melanin pigment[jcasonline.com] […] of rete ridges in a reticulated or fenestrated pattern and a few horn cysts [ Figure 2h ].[cmj.yiigle.com] Skin biopsy from the hypopigmented macule over the lower abdomen also showed elongation of the rete ridges but with pigmentation limited only to the tips of the rete pegs[omicsonline.org]

  • Familial Supernumerary Nipples

    Figure 4: Hyperkeratosis, acanthosis, elongated rete ridges, increased pigmentation of basal keratinocytes from a hyperpigmented, and hyperkeratotic plaque over groin area[e-ijd.org] Epidermis is acanthotic with variable hyperkeratosis and elongation of rete ridges. [13] Histopathological association that is common with Becker's nevus is smooth muscle[e-ijd.org] Histopathological examination revealed hyperkeratosis, acanthosis, elongated rete ridges, and increased pigmentation of basal keratinocytes: these observations were suggestive[e-ijd.org]

  • Sacral Hemangiomas - Multiple Congenital Abnormalities Syndrome

    The relatively few biopsies performed have shown extension of the surrounding normal skin with some acanthosis, elongation of rete ridges and proliferation of capillaries[e-ijd.org] In only one case in this study there was some acanthosis along with elongation of rete ridges. [2] , [3] , [4] Upper dermal edema, telangiectasias and mild infiltration of[e-ijd.org]

  • Psoriasis

    […] of rete ridges with shortening of epidermal keratinocyte transit time due to decreased cyclic guanosine monophosphate.[medical-dictionary.thefreedictionary.com] […] reddish, silvery-scaled maculopapules; the lesions occur predominantly on the elbows, knees, scalp, and trunk, and microscopically show characteristic parakeratosis and elongation[medical-dictionary.thefreedictionary.com]

  • Phenobarbital

    The histological examination of the lesion revealed a hyperplastic epithelium, epithelial acanthosis, and elongated rete ridges as well as obviously enhanced dense collagenous[ncbi.nlm.nih.gov]

  • Balanitis

    […] of rete ridges.[cirp.org] […] which coalesce to form larger "geographic" areas with a white margin. 82 The histology shows spongiform pustules in the upper epidermis with parakeratosis, acanthosis and elongation[cirp.org]

  • Dyschromatosis symmetrica hereditaria

    Histological features include filiform elongation of rete ridges involving the follicular infundibulum and melanocyte proliferation without melanin incontinence.[thinkscience.in] The histology is diagnostic, showing elongation, tufting and deep hyperpigmentation of the rete ridges. [8] Although presence of axillary freckle-like macules points to the[e-ijd.org] […] and increased melanin in of rete ridges, and increased numbers of DOPA-positive melanocytes. [2] , [19] Treatment and prognosis There is very little that can change the course[ijdvl.com]
