Lichen Planus in Ear Not Uncommon
MIAMI BEACH (MedPage Today) -- The autoimmune disease lichen planus may affect the ear more commonly than previously thought, researchers reported here.
Discussion Oral ulcers are common problems seen by dentists but pediatricians also see them. Usually families have are concerned because they are painful and acute. Ulcers are sometime noticed by the physician and not the family as in the case of herpangina or hand-foot and mouth disease. Chronic or recurrent ulcerations present less commonly and therefore it may be more difficult to determine their etiology. Many of the systemic disease causes of oral ulcers are overall infrequent and/or not common in the pediatric age range. Ulcers can be classified in several ways but acute ulcers are usually painful and last less tha...
A 40-year-old female patient without systemic diseases and without the use of medication presented complaints of painful and bleeding wounds on the mouth. On physical examination, multiple bleeding ulcers on the tongue, lip, and jugal mucosa were observed, some with fibrinopurulent pseudomembrane. Laboratory tests excluded autoimmune diseases, venereal diseases, and anemias. Excisional biopsy was performed to exclude the diagnosis of bullous lesions. Anatomohistopathologic examination demonstrated areas of ulcerated connective tissue with chronic inflammatory infiltrate.
Desquamative gingivitis is a generic condition with gingival scaling that can be a manifestation of autoimmune diseases such as lichen planus, pemphigus, and pemphigoid, etc. Diagnosis is based on biopsy of the lesions, hematoxylin and eosin staining (HE), and direct immunofluorescence, and the treatment of choice is the use of corticosteroids. A 59-year-old white female presented with areas of intense erythema and extensive ulcerations spread throughout the gingivae on both arches and on the hard palate, which stopped her from adequately feeding due to pain and bleeding.
Authors: Żychowska M, Batycka-Baran A, Baran W Abstract Background: Interleukin-17 is supposed to play an important role in the pathogenesis of oral lichen planus (OLP). However, there is scarce data in the literature on its significance in the cutaneous variant of the disease. Objectives: To determine the serum level and tissue immunoexpression of IL-17 in cutaneous lichen planus (CLP). Methods: Fifty-two adult patients with CLP, without any significant autoimmune or inflammatory conditions, were included in the first part of the study. The control group consisted of 27 age- and sex-matched healthy volunt...
Conclusion: PECAM-1 was found to be overexpressed in OLP; difference in PECAM-1 expression was noted between the reticular and erosive types. The VAMs could be exploited as a possible therapeutic target in OLP to modulate the disease process thereby reducing the dependency on corticosteroids.
CONCLUSIONS: This study on dry eye confirmed but also refuted many risk factors from smaller epidemiological studies, and discovered numerous new risk factors in multiple etiological categories. The finding that dry eye symptoms are particularly common in young adults is concerning, and warrants further study. PMID: 32376389 [PubMed - as supplied by publisher]
Authors: Chaitanya NC, Reshmapriyanka D, Pallavi K, Ameer S, Appala A, Chowdhary A, Prabhath T, Ratna MP, Sowmya BS, Vaishnavi C, Bontala P Abstract BACKGROUND: Oral lichen planus (OLP) is a T cell-mediated chronic autoimmune disorder directed against antigens secreted by the basal cell layer, with an incidence of 0.02-0.22% in Indian population and showing female predilection. Stress is considered one of the etiological factors in the causation, progression, and recurrence of this disease. OBJECTIVES: To evaluate the levels of serum cortisol, anxiety, and depression in patients with symptomatic OLP and to corr...
This study for the first time compares the expression of the aquaporin-3 (AQP3) gene in oral tissues of a group of OLP patients and a control group. In this study, 30 OLP patients and 30 healthy individuals were selected. The expression of AQP3 gene was measured using Real-Time PCR method. The expression of the gene in the OLP patients was more than the control group. It could be argued that decreased salivation increases the level of expression of the AQP3 gene in an effort to compensate for this deficiency and prevent the onset of xerostomia (compensatory up-regulation).

We report three patients who developed lichen sclerosus et atrophicus superimposed on skin involved by scleredema adultorum of Buschke. Although the association of lichen sclerosus et atrophicus with scleredema adultorum of Buschke could be coincidental, both diseases could be considered part of the spectrum of sclerodermoid disorders with common underlying pathogenetic mechanisms; which could explain the sequential or simultaneous occurrence of both lesions in our patients.
CONCLUSION: It was concluded that vitamin D played an important role in the treatment of oral lichen planus. CLINICAL SIGNIFICANCE: The role of vitamin D in lichen planus needs to be explored. This study may be useful in conducting further study to assess the role in vitamin D supplementation in the treatment of oral lichen planus. PMID: 32584274 [PubMed - in process]
