Extramammary Paget Disease of Oral Mucosa: Case Report with Literature Review.

Extramammary Paget disease (EPMD) of the oral mucosa is an unusual and extremely rare condition, with fewer than ten cases documented. Here, we report a case of EMPD extensively involving oral mucosa and underlying salivary ducts in a 72-year-old male and review published clinical, histologic, immunophenotypic, and prognostic features of this rare entity.

Human papillomavirus 16/18/45 are not the most frequent genotypes in African American women: analysis in cervical Papanicolaou smears of women in an inner-city hospital.

INTRODUCTION: Cervical cancer is considered the most common human papillomavirus (HPV)-associated disease in women. Primary and secondary prevention methods have been established through Pap tests, HPV molecular testing, and vaccines. Although the most common high-risk HPV (HR-HPV) genotypes in the United States are 16, 18, and 45, there is reported ethnic disparity in the distribution of these genotypes. MATERIALS AND METHODS: Data analysis of HPV genotype results on cervical pap tests in our institution between late 2018 and early 2020 was performed. The distribution of HPV genotypes in each Bethesda category was evaluated. RESULTS: A total of 13,160 smears were evaluated; 75.5% were from African American women. Of those tested for HR-HPV (10,060), 1412 (14%) were HR-HPV positive. In all diagnostic categories of the Bethesda classification system, non-16/18/45 HR-HPV genotypes were more prevalent, ranging from 60.8% even in high-grade squamous intraepithelial lesion to 90.4% in negative for intraepithelial lesion or malignancy. CONCLUSIONS: In this study with a predominantly African American population, non-16/18/45 HR-HPV genotypes were prevalent in the majority (60.8%) of high-grade squamous intraepithelial lesion cases. Ethnic variability should be considered when deciding which HPV genotypes to integrate into the HPV vaccine.

Sebaceous Lymphadenoma: Radiology-Pathology Correlation.

Sebaceous lymphadenoma is a rare salivary gland neoplasm most commonly occurring in the sixth to eighth decades of life. Cross sectional imaging typically demonstrates a multicystic expansile mass, most commonly occurring in the parotid gland, where the radiographic differential diagnosis would include Warthin tumor in this location and age group. Ultimately, the diagnosis is confirmed with the histopathologic findings of tubuloglandular epithelial profiles with sebaceous differentiation and cystic change set within a dense, benign lymphocytic infiltrate. These features are exemplified in this sine qua non radiology-pathology correlation article.
