135 Possible Causes for Elongation of Rete Ridges

  • Deficiency of Interleukin-36-Receptor Antagonist

    In grammar, a ditransitive verb is a verb which takes a subject and two objects which refer to a theme and a recipient. According to certain linguistics considerations, these objects may be called direct and indirect, or primary and secondary. This is in contrast to monotransitive verbs, which take only one object,[…][]

  • Dowling-Degos Disease

    A biopsy specimen revealed elongated epidermal rete ridges with basilar hyperpigmentation in a filiform pattern.[] In addition to thin branching and elongation of rete ridges with basal hyperpigmentation, immature hair follicles surrounded by fibrosis and a lace-like pattern of the hair[] Figure 2: (a) Skin biopsy from the hyperpigmented macules showing hyperkeratosis, elongated and bifurcated rete ridges (‘antler like’ rete ridges) with increased melanin pigment[]

  • 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 ).[] Image C Image D Histology: Differentiated PEIN (HPV-unrelated): elongated rete ridges with abnormal maturation (pinker cytoplasm); whorling and keratin earl formation.[] Histopathological examination demonstrates hyperkeratosis, parakeratosis, acanthosis, elongated rete ridges, and mild lower epidermal dysplasia with a nonspecific dermal inflammatory[]

  • Benign Migratory Glossitis

    When rete ridges are not elongated, the pathologist should consider Reiter's syndrome as a diagnostic possibility.[] Fig. 1 Psoriasiform mucositis. a Histological photomicrograph illustrating hyperkeratotic squamous epithelium with elongated rete ridges, dilated blood vessels in the papillary[] Rete ridges are typically thin and considerably elongated, with only a thin layer of epithelium overlying connective tissue papillae (Figures 7 & 8).[]

The basal layer shows increased melanin pigmentation.[]

    Sections prepared from the skin of the tip of the patient's finger showed marked epithelial hyperplasia with uniform elongation of rete ridges and supra-papillary thinning[] Histopathological examination of the lesion revealed psoriatic changes with elongated rete ridges, mild acanthosis with parakeratosis.[] Acanthosis and irregular elongation of the rete ridges were also noted, with ectatic vessels and a lymphocytic inflammatory cell infiltrate.[]
