Leukemia is a hematological malignant disease with various clinical symptoms. Due to the fatal nature of the disease, early detection is important. Oral manifestations include ulcers and gingival enlargement with bleeding. Moreover, myeloid sarcoma or opportunistic infections may also occur. This report introduces a 31-year-old male presenting with generalized gingival enlargement with bleeding and another 81-year-old female with neoplasm on the left retromolar area. Both were diagnosed as acute monocytic leukemia. These cases implicate that gingival enlargement or mucosal lesion in the oral cavity may represent underlying systemic diseases. Related to this, it has to be reminded that making timely diagnosis and referral according to the clinical findings is crucial.

Objectives: The purpose of this study was to compare oral symptoms in middle school and high school students of multicultural and ordinary families in Korea. Methods: We used data from the web-based survey of the National 2014 Korean Youth Risk Behavior of Korean Center for Disease Control. A total of 71,174 subjects responded about their father or mother's Korean nationality. We classified a subject as an adolescent of a multicultural family if aparticipant's father or mother's nationality was not Korean. Data was analyzed using SPSS Ver. 19.0. Results: High school students of multicultural families have experienced more oral disease symptoms, compared to high school students of ordinary families. After adjusting general characteristics and oral health behaviors, high school students of multicultural families experienced 1.78 times higher frequency of oral disease symptoms compared to high school students of ordinary families. Conclusions: The family type and age characteristics of adolescents should be considered when establishing policies and institutions targeting adolescents to improve oral health.

Mucous membrane pemphigoid is uncommom disease in oral cavity and synonymous with cicatricial pemphigoid. This disease is caused by autoimmune reaction that autoantibody reacts antigen located in basement membrane and epithelium is separated from underlying connective tissue. It affects female over sixth decade, commonly. Oral mucosa, especially gingiva is common site but conjunctival, nasal, pharyngeal, laryngeal, esophageal, varginal mucosa and skin are involved. Intraoral findings show Nikolsky sign, irregular erythema, erosion, vesicle, and ulceration at mucous membrane. To differentiate from diseases of positive Nikolsky sign, should perform histologic, immunologic test. Histologic features show subbasilar cleft and direct immunologic features show IgG, C3 deposits at basement membrane in linear pattern. Mucous membrane pemphigoid is incurable disease because symptoms are repetitively improved or worsed for several years. Patiens are commonly managed with topical and systemic steroid. To avoid side effects of prolonged steroid therapy and to maintain immunosupressive effects, combination therapy of azathioprine with steroid is effective. This case reports that mucous membrane pemphigoid is diagnosed based on clinical and histologic features, is treated with topical, systemic steroid and azathioprine therapy.

In this study, we investigate the emergence of bullous pemphigoid (BP) after the administration of the Severe Acute Respiratory Syndrome-Coronavirus Disease 2019 (SARSCOVID-19) vaccine. The study presents two cases of women, aged 47 and 53, diagnosed with BP following SARS-COVID-19 vaccination. BP is a common autoimmune blistering disorder prevalent among older populations, with an incidence rate ranging from 2 to 40 cases per million individuals. This condition arises when autoantibodies target adhesive proteins in the skin, resulting in blister formation and mucosal erosion. Drug-induced bullous pemphigoid (DIBP) shares similarities with the classic form of BP but may be influenced by medication usage. Notably, DIBP exhibits distinct characteristics, such as affecting a younger demographic and involving mucosal regions more prominently than classic BP. The growing incidence of BP is linked to factors such as an aging population and the rise of drug-induced cases. This case report provides valuable insights into comprehending DIBP, elucidating post-vaccination discomforts, particularly those related to oral lesions and the exacerbation of existing lesions. By elucidating these aspects, we aim to advance the understanding of DIBP within the medical community.

Immunoglobulin G4 (IgG4)-related dacryoadenitis and sialoadenitis (IgG4-DS) are part of a multiorgan fibroinflammatory condition of unknown etiology termed IgG4-related disease (IgG4-RD), which has been recognized as a single diagnostic entity for less than 15 years. Histopathologic examination is critical for diagnosis of IgG4-RD. CD4+ T and B cells, including IgG4-expressing plasma cells, constitute the major inflammatory cell populations in IgG4-RD and are thought to cause organ damage and tissue fibrosis. Patients with IgG4-RD who have active, untreated disease exhibit significant increase of IgG4-secreting plasmablasts in the blood. Considerable insight into the immunologic mechanisms of IgG4-RD has been achieved in the last decade using novel molecular biology approaches, including next-generation and single-cell RNA sequencing. Exploring the interactions between CD4+ T cells and B lineage cells is critical for understanding the pathophysiology of IgG4-RD. Establishment of pathogenic T cell clones and identification of antigens specific to these clones constitutes the first steps in determining the pathogenesis of the disease. Herein, the clinical features and mechanistic insights regarding pathogenesis of IgG4-RD were reviewed.

The objective of this study was to assess the possibility of detecting Foot-and-Mouth Disease Virus (FMDV) from the herd-based oral fluids specimens collected by the cotton ropes from pig farms that were found as FMDV nonstructural protein (NSP) antibodies positive. The cotton ropes were applied to detect FMDV in the selected pig farms which NSP antibodies were continuously detected in 2016, including the one pig farm which FMDV antigen were detected at the specimens from the pigsty environment. As the result, FMDV antigen were not detected in the oral fluid specimens collected by the cotton ropes. Theoretically, to detect FMDV antigen from the pigs with NSP antibodies has very low possibility because FMDV antigen disappeared at the time when NSP antibodies were produced by FMDV. Therefore, in order to detect FMDV antigen from the oral fluids using the cotton rope, it would be more effective to be applied to target the FMDV infected pigs rather than the NSP antibodies positive pigs. The collected oral fluids using cotton rope could be useful test specimens to monitor high-density pig populations for FMDV infection. Then, oral fluids sampling using cotton rope will be used for the efficient FMDV surveillance to detect FMDV antigen.

The endoplasmic reticulum (ER) is crucial for protein synthesis, transport, and folding, as well as calcium storage, lipid and steroid synthesis, and carbohydrate metabolism. Endoplasmic reticulum stress (ERS) occurs when misfolded or unfolded proteins accumulate in the ER lumen due to increased protein secretion or impaired folding. While the role of ERS in disease pathogenesis has been widely studied, most research has focused on extraoral diseases, leaving the role of ERS in intraoral diseases unclear. This review examines the role of ERS in oral diseases and oral fibrosis pathogenesis. A systematic search of literature through July 2023 was conducted in the MEDLINE database (via PubMed) using specific terms related to ERS, oral diseases, and fibrosis. The findings were summarized in both table and narrative form. Emerging evidence indicates that ERS significantly contributes to the pathogenesis of oral diseases and fibrosis. ERS-induced dysregulation of protein folding and the unfolded protein response can lead to cellular dysfunction and inflammation in oral tissues. Understanding the relationship between ERS and oral disease pathogenesis could offer new therapeutic targets for managing oral health and fibrosis-related complications.

Angiolymphoid hyperplasia with eosinophilia(ALHE) is a benign subcutaneous lesion that primarily affects head and neck region. It is characterized by single or multiple nodules in the subcutaneous tissue associated with eosinophilia in the peripheral blood. Kimura's disease, originally reported by Kimura et al., is similar lesion with ALHE in the clinical and histopathological aspects. There has been considerable controversy about the relation between Kimura's disease and ALHE. In Korea, 26 cases of Kimura's disease and ALHE have been reported since 1975. We present a case of recurred ALHE occurring on the left cheek in a 58-year-old woman. Including this case, we summarized all cases that were reported as Kimura's disease or ALHE in Korea through literature review. We also give an outline of clinical and histopathological characteristics of cases reported in Korea.
