hrHPV positivity in ASC-US Papanicolaou tests from women with treated HPV- and non-HPV-related gynecologic malignancies.

Introduction: Although the utility of high-risk human papillomavirus (hrHPV) testing is established in the triage of ASC-US Papanicolaou tests from the general population, its role in women who have been treated for cervical cancer and other HPV-related cancers is less clear.

Materials And Methods: Records of patients with ASC-US Papanicolaou tests and HPV testing results submitted by our gynecologic oncology service with a history of malignancy between 2006 and 2012 were reviewed.

Results: Thirty-nine women with a history of treatment for HPV-related cancer and ASC-US Papanicolaou tests who had undergone hrHPV testing were identified.

Immunohistochemical characterization of squamous differentiation and morular metaplasia in uterine endometrioid adenocarcinoma.

Squamous differentiation (SD) and morular metaplasia (MM) are frequently present in uterine endometrioid adenocarcinoma (EAC) and can mimic areas of solid tumor. We used immunohistochemical stains to further characterize these lesions, and to determine which markers would help to distinguish these metaplasias from areas of solid growth in EAC. The pathology database was searched for diagnoses of EAC from 1997 to 2007, the hematoxylin and eosin-stained slides were reviewed, and 143 cases with SD, MM, or both (SD+MM) were identified.

Fine-needle aspiration of metanephric adenoma of the kidney with clinical, radiographic and histopathologic correlation: a review.

Metanephric adenoma of the kidney is an uncommon benign epithelial neoplasm with only a small number of reports that describe its cytologic features. We describe two additional cases of metanephric adenoma diagnosed on fine-needle aspiration biopsy and review the available literature. Our cases showed similar cytology and were composed of cellular smears with numerous clusters of small, oval to round cells arranged in a microfollicular pattern and papillary configurations.

Cytologic features of sclerosing hemangioma of the lung on crush preparations.

Sclerosing hemangioma of the lung is a rare benign neoplasm. The majority of the literature published on sclerosing hemangioma has focused on the histologic features, while only a few case reports have described the cytologic features. We report two additional cases of sclerosing hemangioma of the lung in which the cytologic material was prepared at the time of frozen section.

An unusual clinical presentation of merkel cell carcinoma: a case report.

Introduction. Merkel cell carcinoma is a rare, aggressive neuroendocrine cell carcinoma arising in the sun-exposed skin of elderly patients. Most of these tumors are located in the dermis.
