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 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.

Atypical oral candidiasis in a psoriatic patient during targeted immunotherapy with an interleukin 17 inhibitor (secukinumab).

Background: Secukinumab is a human monoclonal antibody immunoglobulin that neutralises interleukin (IL)-17A, and as such, is effective in the treatment of psoriasis. However, as IL-17A is essential in protection against fungal infections, patients treated with this drug may develop candidiasis. This report presents a case of atypical oral candidiasis occurring during targeted drug immunotherapy with an interleukin 17 (IL-17) inhibitor (secukinumab), with the aim of emphasisinge the necessity of periodical oral health assessment and monitoring.

CLA and CD62E expression in oral lichen planus lesions.

Objective: There are few reports on the migration of CLA+ T cells through E-selectin in cutaneous lichen planus, with only one study on oral lichen planus (OLP). This study aimed to analyze CLA expression and assess whether there is a correlation with E-selectin (CD62E) in OLP lesions.

Material And Methods: Biopsies were performed on 11 patients including two areas: one without clinical and histopathological features of OLP [perilesional group (PLG)] and the other with clinical and histopathological features of OLP [OLP group (OLPG)].

Oral lichen planus: study of 21 cases.

Background: Lichen planus is considered to be the most common dermatological disease involving the oral mucosa.

Objective: To investigate the profile, clinical features, and the presence of dysplasia and candidiasis in patients with oral lichen planus.

Methods: A total of 21 patients were selected from 258 patients at risk for oral cancer development.

Actinic prurigo of the lip: Two case reports.

Actinic prurigo is a photodermatosis that can affect the skin, conjunctiva and lips. It is caused by an abnormal reaction to sunlight and is more common in high-altitude living people, mainly in indigenous descendants. The diagnosis of actinic prurigo can be challenging, mainly when lip lesions are the only manifestation, which is not a common clinical presentation.
