Pleomorphic adenoma of hard palate: Review of updated literature and "case report".

RATIONAL: Pleomorphic adenoma (PA) is a rare benign tumor mainly affecting the major salivary glands, known for its diverse histological appearances that can mimic malignancies. When it occurs in the hard palate it present diagnostic and management challenges compared to other sites due to the anatomical location and potential proximity to critical structures. This case reports a rare presentation PA starting as an ulcer, alongside a review of rare cases of PA reported in last 5 years. We aim to highlight clinical challenges and emphasize the need for awareness in diagnosis of this diverse entity amongst the clinicians before reaching a definitive conclusion. PATIENT CONCERNS: A 41-year-old female reported an asymptomatic large swelling on the right side of the posterior palatal region. Clinical diagnosis revealed a firm, rubbery, and non-tender swelling of approximately 4 cm × 4 cm diameter. A triangular incisional biopsy was performed to confirm the diagnosis. DIAGNOSIS: The histopathological evaluation confirmed the presence of a PA with a well-encapsulated and compressed salivary gland. A wide surgical dissection was made to remove the entire encapsulated tumor mass, including the mucoperiosteum and eroded bone of the palate. The borderline of the tumor was carefully identified in the surrounding healthy tissue. The hemostasis was obtained using a simple interrupted suture. LESSON: The diagnosis of PA is difficult as it usually involves extensive squamous and mucous metaplasia, confusing it with malignant disorders. Histopathological and clinical examinations are important for differentiating this lesion from other tumors. Complete surgical excision is reported as the first line of treatment.

Is There a Relationship between Salivary Cortisol and Temporomandibular Disorder: A Systematic Review.

BACKGROUND: This systematic review examines and evaluates the relationship between salivary cortisol levels and temporomandibular disorder (TMD) in young adult patients. METHOD: Six databases-PubMed, Scopus, Web of Science, Google Scholar, ProQuest, and Cochrane Library-were utilized to screen eligible studies. A systematic search was performed based on PECO questions and eligibility criteria. The research question for this review was "Do salivary cortisol levels correlate with TMD in individuals aged 18-40?" The risk of bias for quality assessment was determined by the Cochrane tool. PRISMA guidelines were followed while performing this review. RESULT: A total of fourteen studies were included in this review. Of these, eleven were observational studies (four cross-sectional and seven case-control), and three were randomized control trials. Eleven of the included studies presented a low to moderate risk in the qualitative synthesis. The total sample size of the included studies was 751 participants. The included studies suggest higher salivary cortisol levels in TMD patients than in healthy individuals. CONCLUSIONS: The findings of this review indicate higher salivary cortisol levels in adult patients with TMD than in healthy controls. Thus, supportive psychological treatment and clinical modalities should be provided to patients with TMD. Moreover, higher-quality studies with low heterogeneity are required to support this finding.

Proliferative verrucous/multifocal leukoplakia: Updates and literature review "case report".

RATIONALE: Proliferative verrucous leukoplakia (PVL) is a multifocal, slowly evolving lesion that resists all types of treatment and has a high propensity for malignant transformation into oral squamous cell carcinoma. Lack of awareness and acquaintance with white lesions of the oral cavity makes it difficult to diagnose. Besides being rare, PVL significantly aggressive, so clinicians need to be aware of it carefully. Therefore, it is recommended to have the earliest possible diagnosis and total excision of this lesion. We report this case to present typical clinical and histologic features of PVL so a For the purpose of sensitizing clinician. PATIENT CONCERN: A 61-year-old female came to the clinic concerning of recurring painless, white patch on the tongue 2 months ago, associated with oropharyngeal dryness. DIAGNOSES: This case satisfies these major and minor criteria to diagnosed PVL. INTERVENTION: An excisional biopsy of the lesion was done to check for the presence of dysplasia, as lesions were persisting. Hemostasis was achieved with single interrupted sutures. OUTCOME: no recurrence has been observed since excisional 1 year follow-up. LESSON: The key feature is early detection, precisely in cases of PVL it is critical for better treatment outcomes, lifesaving, quality-of-life enhancement. To detect and treat any potential pathologies, clinicians should meticulously examine the oral cavity and patients have to be aware and informed of the importance of regular screenings. This lesion is resistant to the presently available treatment modalities; therefore, total excision with free surgical margins is critical combined with a lifelong follow-up.
