Linear IgA dermatosis adult variant with oral manifestation: A rare case report

Ocular involvement in oral vesiculobullous diseases: A review on reported cases in the literature

Introduction

Vesiculobullous disorders are a group of autoimmune diseases manifesting as chronic ulcers in the oral cavity. Ocular involvement may accompany oral ulcers and cause various problems for patients. This review summarizes the data regarding ocular involvement in patients with oral vesiculobullous.

Methods

Web of Science, Scopus, PubMed/MEDLINE, and Embase electronic databases were searched according to related keywords. Finally, 58 articles were included, all of which were case reports or series. Characteristics such as the age and sex of patients, location and type of oral lesion, type of ophthalmic injury, the interval between oral and ocular lesion, and treatment of oral and ocular disorders were summarized in tables.

Results

Eye involvement was 1.6 times more prevalent in women, and most patients were between 30 and 60 years old (67.4 %). Pemphigus vulgaris accounted for almost half of the cases (48.4 %), though lichen planus is more prevalent in the general population. The most frequently affected oral site was the buccal mucosa (17.5 %), and oral ulcers usually presented as erythema, erosion, or inflammation (22.7 %). Conjunctivitis was the most common type of eye involvement (18.4 %), and ophthalmic lesions regularly appeared 12-60 months after the development of oral lesions (30.1 %). Blindness was reported in only one case. Corticosteroids and immunosuppressives were the most frequent oral and ocular lesion therapies.

Conclusion

Considering the serious burdens of any ocular injury, monitoring the ocular health of patients with oral vesiculobullous diseases is highly recommended in high-risk cases, especially middle-aged women with oral pemphigus vulgaris.

Chronic Oral Lesions

Chronic oral mucosal lesions can be associated with several mucocutaneous diseases. This article reviews the autoimmune and immune-mediated, reactive, genetic, and infectious diseases that may present with chronic oral and/or cutaneous manifestations and provides a rational approach to diagnosis and management.

Histologic characterization of cellular infiltration in autoimmune subepidermal bullous diseases in a tertiary hospital in Saudi Arabia

Background

Autoimmune subepidermal bullous dermatoses have similar clinical features to those of a spectrum of immune reactants at the dermoepidermal junction (DEJ). It is difficult to obtain a precise diagnosis without an immunofluorescence assay because of their similar clinical presentations. The aim of this study was to describe the cellular cutaneous infiltration among autoimmune subepidermal bullous dermatoses.

Materials and methods

This retrospective analysis was conducted at a hospital in Riyadh, Saudi Arabia using biopsy-based data collected from 65 patients.

Results

Spongiotic changes, neutrophils, and lymphocyte infiltrations in the epidermis differed among the subepidermal bullous diseases. The DEJ showed a difference in the extent of neutrophil infiltration. The dermis showed differences in perivascular lymphocytic infiltration, neutrophilic infiltration, eosinophilic infiltration, and dermal edema.

Conclusion

The dermal and DEJ showed most of the histopathologic changes in subepidermal autoimmune bullous dermatoses.

Exploring beyond the oral mucosa in patients affected with autoimmune blistering diseases: the importance of endoscopic procedures

Autoimmune blistering diseases (AIBD) comprise several entities characterized by the presence of autoantibodies targeted against structural proteins either in desmosomes or in the dermoepidermal junction of polystratified squamous epithelium. Patients develop blisters, erosions in cutaneous surfaces or mucosas. Diagnosis is based on the characteristic mucocutaneous lesions, the typical findings on histological studies and direct immunofluorescence assays, and the presence of specific autoantibodies against the epidermal antigens. It may not be possible for dermatologists to appropriately explore the nose and throat (NT). Thus, a clinical exploration by endoscopic procedures of NT may be a useful tool during the conventional dermatological exam. The aims of this review are to draw attention to the most frequent NT manifestations in AIBD patients, and underline the utility of endoscopic procedures to achieve a more successful and rationale management of patients. Additionally, we will provide brief information related to the anatomical structures and type of epithelium in NT areas which may explain the extent and type of NT involvement in AIBD. Endoscopic exploration in AIBD patients is important for several reasons. Firstly, it will allow the real NT mucosal involvement in each patient to be determined, thus making a differential diagnosis during the endoscopic exam possible, based on the localization of mucosal lesions. Secondary mucosal morbidity can also be ruled out. Secondly, the clinical response to treatment may be established, especially in NT mucosa, as these are anatomical areas subjected to important local traumas, and physiological functions such as breathing, swallowing, speech production and phonation may be damaged. Therefore, a multidisciplinary management in AIBD is mandatory by both dermatologists and otorhinolaryngologists, adding the clinical exploration by endoscopic procedures of NT to the conventional dermatological exam in all AIBD patients, irrespective of whether they exhibit associated symptoms.
