Involucrin is a soluble protein precursor of the cross-linked envelope present in the submembranous zone of human stratum corneum, and subsequently demonstrated in stratified squamous epithelia. The immunoperoxidase technique was used to assess the distribution of involucrin in 107 normal and 318 abnormal tissues. With few exceptions, involucrin was(More)
p16, Ki-67, and BD ProExC (TriPath Imaging, Inc., Burlington, NC) have each been shown to be helpful adjuncts in the diagnosis and grading of human papillomavirus-associated cervical intraepithelial neoplasia. However, no clear guidelines are available regarding their use in routine practice. This study was designed to evaluate the efficacy of the 3 stains(More)
OBJECTIVE To compare clinical and histologic features between fallopian tube cancers in women with germline BRCA mutations and sporadic cases. METHODS Twenty-eight patients with fallopian tube cancer had BRCA mutation testing using multiplex polymerase chain reaction and protein truncation testing. Histologic slides were reviewed by 2 pathologists, and(More)
OBJECTIVE Lynch syndrome (LS) is characterized by a high lifetime incidence of colorectal cancer and gynecologic malignancies such as endometrial and ovarian cancer. Identification of LS families is important as it allows for heightened cancer screening which decreases colorectal cancer mortality. The original 1996 Bethesda guidelines included two(More)
BD ProEx C (ProEx C) is a recently developed immunocytochemical assay that targets the expression of topoisomerase II-alpha and minichromosome maintenance protein-2, 2 genes shown to be overexpressed in cervical cancers. Recent studies validated this reagent in liquid-based cytology specimens and suggested its usefulness as an adjunct in the diagnosis of(More)
PURPOSE To elucidate molecular pathways contributing to metastatic cancer progression and poor clinical outcome in serous ovarian cancer. EXPERIMENTAL DESIGN Poor survival signatures from three different serous ovarian cancer datasets were compared and a common set of genes was identified. The predictive value of this gene signature was validated in(More)
Diffuse idiopathic neuroendocrine cell hyperplasia (DIPNECH) can be difficult to diagnose in resections for lung tumors and other conditions, as variable diagnostic criteria and definitions of "diffuse" and/or "idiopathic" have been used in the literature. We reviewed 70 consecutive lung wedge biopsies and resection specimens with multifocal neuroendocrine(More)
The differential diagnosis of perineal biopsies can include squamous intraepithelial lesions, extramammary Paget's disease, and melanoma. Less frequently two of these lesions coexist. BD ProEx C is a recently developed immunoassay that targets expression of two genes shown to be associated with cervical cancer. Immunostaining for ProEx C has been validated(More)
Pulmonary carcinoid tumors are currently classified as typical or atypical based on the mitotic index (2 per 10 hpf) and/or the presence of necrosis. Following incorporation of the Ki-67 index into the classification of GI carcinoid tumors, our oncologists have also been requesting this test as part of the work-up of pulmonary carcinoid tumors although(More)
OBJECTIVES To determine the impact of venous thromboembolism (VTE) during primary treatment of ovarian clear cell carcinoma (OCCC) on survival. METHODS After Institutional Review Board approval, 74 cases of OCCC were retrieved from our pathology files. Clinical and pathological data were obtained by medical record and pathology review. Standard(More)
