Challenges in the assessment of epithelial dysplasia in oral lichen planus and oral lichenoid lesion: Inter and intra-observer variability of the WHO criteria and binary system.

Background: Assessment of oral epithelial dysplasia is the gold standard for investigating the risk of malignant progression. The World Health Organization (WHO) methods and the binary system have limitations. This study assess the inter- and intra-observer variability of the architectural and cytological criteria and the classification of the presence and degree of epithelial dysplasia in oral lichen planus (OLP) and oral lichenoid lesion (OLL), using both the 2017 WHO criteria and the binary system.

Challenging of treating patients with exfolliative cheilittis: Report of two cases.

Cheilitis is a term given to the inflammation that occurs in the vermillion of the lips. The exfoliative type is an uncommon form of cheilitis, which is characterized by inflammation and desquamation of the lip. It can cause aesthetic problems and compromise daily eating and phonation.

Oral candidiasis in patients hospitalised in the intensive care unit: Diagnosis through clinical and cytopathological examinations.

Objective: To evaluate the prevalence and clinical aspects of oral candidiasis in patients hospitalised in the intensive care unit.

Methods: This is a longitudinal and prospective study that included 48 participants hospitalised in the intensive care unit. Sociodemographic data, presence of systemic disorders, use of medications, laboratory tests, cause of hospital admission, type of breathing, and length of hospital stay were obtained from medical records.

Lymphocyte and CD62E expression in lichen planus and lichenoid reaction.

Background: It is difficult to distinguish the clinical and histopathological aspects of oral lichen planus lesions from those of oral lichenoid reaction. Some criteria were proposed to distinguish them, mainly because they have different biological behaviors. The aim of the present study was to compare the lymphocyte population and the expression of E-selectin between these lesions.

Oral lichenoid lesion in association with chemotherapy treatment for non-Hodgkin lymphoma or lichen planus? Review of the literature and report of two challenging cases.

Background: The diagnosis of oral lichenoid lesions (OLL) remains a challenge for clinicians and pathologists. Although, in many cases, OLL cannot be clinically and histopathologically distinguishable from oral lichen planus (OLP), one important difference between these lesions is that OLL has an identifiable etiological factor, e.g.

Oral candidiasis in patients with haematological diseases: Diagnosis through clinical and cytopathological examinations.

Objective: This study is the first to analyse the prevalence of oral candidiasis in onco-haematological patients by physical and oral cytopathological examinations.

Methods: This is a cross-sectional and observational study with a retrospective sample composed of participants hospitalised in the haematology clinic, who were diagnosed with haematological diseases. All participants received an oral mucosal examination and scraping from oral mucosa.

Congenital sebaceous choristoma of the tongue: A rare case report.

The most common oral choristomas are consisted of thyroid tissue and bone. The presence of sebaceous glands in the oral mucosa, especially in the buccal mucosa and labial mucosa, is often considered a normal anatomical variation since they are observed in about 80% of the population and are called ectopic sebaceous glands or Fordyce's granules. However, the presence of these glands on the tongue is rare, with only 11 cases in the dorsum of the tongue reported in the English literature, and it is considered a choristoma.

An integrative review of oral manifestations in patients with COVID-19: signs directly related to SARS-CoV-2 infection or secondary findings?

We conducted an integrative review on oral manifestations in patients with COVID-19 based on the current available literature evidence. A bibliographic search was carried out on March 11, 2021, among published studies in the years 2019-2021 in the PubMed database and based on the search strategy ("COVID-19" AND "oral lesions" OR "oral mucositis" OR "oral manifestation"). After applying the inclusion and exclusion criteria, 29 articles were considered suitable for this review.

Oral Lichen Planus Associated With Lichen Planus Pigmentosus and Lichen Sclerosus in Monozygotic Twins.

Lichen planus (LP) is a mucocutaneous immune-mediated disease of unknown etiology. It is more prevalent in women and usually occurs between the third and sixth decades of life. Oral lesions may or may not be associated with skin and genital lesions.
