“…In other published reports, inflammatory cells such as foamy macrophages, lymphocytes, and plasma cells, epithelial cells, and high-protein material have been identified as LEC content. 8,[11][12][13] Hemorrhagic, keratinized, and infectious content have also been reported. 6,9,14 In this study, hyperintensity on T1-weighted images suggests high cellular density, high protein density, or hemorrhage as the cyst content.…”

Purpose This study aimed to determine the MRI features of sporadic/simple lymphoepithelial cyst (SLEC) of the parotid gland. Methods Ten patients (seven men, three women; mean age, 60 years; age range, 38–77 years) with histopathologically and clinically proven SLEC of the parotid gland who underwent MRI before surgical resection were enrolled in this study. No enrolled patient had HIV infection or Sjögren syndrome. MRI findings of SLEC were retrospectively assessed. Results We confirmed 10 SLECs larger than 10 mm with a mean maximum diameter of 26.6 mm (range, 12–42 mm). Nine patients (90%) had a single cyst, and one (10%) had a large cyst accompanied by small cysts (<10 mm) within the ipsilateral parotid gland. Eight SLECs (80%) were unilocular, and two (20%) were bilocular, with complete septa. Among seven SLECs (70%) with internal septa, five unilocular SLECs (50%) had incomplete septa. Six SLECs (60%) had eccentric cyst wall thickening, and five (50%) were surrounded by small solid nodules that were isointense relative to lymph node. On T1-weighted images, all cyst contents were homogeneously hyperintense relative to cerebrospinal fluid. Conclusion SLECs of the parotid gland are usually single unilocular lesions. Internal septa, eccentric cyst wall thickening, and small solid nodules surrounding the lesion were often observed. Cyst contents are always homogeneously hyperintense on T1-weighted images.

“…Lymphoepithelial cysts are benign unilocular or multilocular cysts that can occur in the head and neck region, including the salivary glands. Recently, it was found that patients with HIV can present with multiple and bilateral lesions 10 . Sebaceous lymphadenoma is a rare benign tumor characterized by epithelium with sebaceous differentiation in a background of hyperplastic lymphoid tissue 11 .…”

The term “Atypia” has been employed to describe a wide spectrum of cytomorphologic features associated with reactive/inflammatory processes as well as those suspicious for neoplasms in cytology. Similar to other cytopathology reporting systems, the Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) has reserved the atypical category for cytology specimens lacking quantitative and/or qualitative cytomorphologic features to be diagnosed with confidence as either non‐neoplastic or neoplastic. In MSRSGC, the atypical category is associated with a risk of malignancy and recommendation for clinical management. In this review, we discuss the value of atypical diagnostic category of MSRSGC in both cystic and non‐cystic salivary gland lesions by evaluating our institutional case cohort.

“…Tratando-se de pacientes HIV positivo e lesões bucais, não só linfócitos T CD4 abaixo de 200 cél/mm 3 , como também uma carga viral elevada, higiene bucal precária, uso de tabaco e xerostomia podem contribuir para o desenvolvimento precoce dessas lesões bucais 11,15 .…”

Introdução: Pacientes portadores do vírus da imunodeficiência humana apresentam susceptibilidade a desenvolver alterações bucais, em que estas estão intimamente relacionadas ao grau de carga viral e consequentemente a contagem de células linfocitárias. Objetivo: Traçar um perfil clínico-epidemiológico de alterações bucais em pacientes portadores do HIV. Material e Método: Realizou-se uma revisão onde foram analisados artigos científicos obtidos da base de dados PubMed. Foram incluídos os estudos do período de 2000 a 2017, de acordo com os descritores: HIV; Linfócitos T CD4-positivos; Doenças da boca, bem como a associação dos termos. Totalizando-se 19 estudos para realização da pesquisa. As pesquisas que não se enquadraram a esses critérios foram excluídas. Os dados foram analisados a partir de estatística descritiva. Conclusão: Conclui-se que a cavidade oral é a área de maior frequência para manifestações do HIV/AIDS sendo a candidose, leucoplasia pilosa e as doenças periodontais as lesões mais ocorrentes em todo o mundo. Em relação ao sexo, conclui-se que a maior prevalência varia de acordo com a população estudada, sendo o sexo masculino o mais prevalente no Brasil, porém o sexo feminino quando afetado possuíam idade mais precoce.Descritores: HIV; Linfócitos T CD4-Positivos; Doenças da Boca.
