BACKGROUND Ductal carcinoma in situ (DCIS) of the breast has been diagnosed increasingly since the advent of mammography. However, the natural history of these lesions remains uncertain. Ductal carcinoma in situ of the breast does not represent a single entity but a heterogeneous group with histologic and clinical differences. The histologic subtype of DCIS seems to have an influence on its bio...

IMPORTANCE Nonchordomatous clival lesions are rare and represent a wide range of different benign and malignant pathologies. For an accurate and specific final diagnosis, biopsy procedures and/or resections followed by histologic examination are mandatory. OBJECTIVE To illustrate the challenges in obtaining a final histologic diagnosis in patients with various types of clival lesions. DESIG...

Classifying adult gliomas remains largely a histologic diagnosis based on morphology; however astrocytic, oligodendroglial and mixed lineage tumors can display overlapping histologic features. We used multiplexed exome sequencing (OncoPanel) on 108 primary or recurrent adult gliomas, comprising 65 oligodendrogliomas, 28 astrocytomas and 15 mixed oligoastrocytomas to identify lesions that could ...

OBJECTIVE The purpose of this study was to compare the spectral characteristics of lipids, choline-containing compounds, and glutamine-glutamate complex assessed with (1)H-MR spectroscopy with the histologic findings in patients with chronic hepatitis C. SUBJECTS AND METHODS Nine healthy controls and 30 patients with biopsy-proven hepatitis C virus-related liver disease participated in this p...

OBJECTIVES/HYPOTHESIS To analyze the impact of different types of perineural invasion (PNI) in squamous cell carcinoma (SCC) of the oral cavity on overall survival and recurrence rate, with a special focus on histologic subtypes and tumor stage. STUDY DESIGN Retrospective case-control study with clinicopathological analysis. METHODS Seventeen patients who received primary surgical treatment...

BACKGROUND Automated cell recognition from histologic images is a very complex task. Traditionally, the image is segmented by some methods chosen to suit the image type, the objects are measured, and then a classifier is used to determine cell type from the object's measurements. Different classifiers have been used with reasonable success, including neural networks working with data from morph...

BACKGROUND AND PURPOSE A number of parameters derived from dynamic contrast-enhanced MR imaging and separate histologic features have been identified as potential prognosticators in high-grade glioma. This study evaluated the relationships between dynamic contrast-enhanced MRI-derived parameters and histologic features in glioblastoma multiforme. MATERIALS AND METHODS Twenty-eight patients wi...

BACKGROUND The progression of diabetic nephropathy (DN) is frequently determined by clinical parameters; however, the predictive value of histologic lesions remains largely unknown. Our aim was to evaluate the relationship between histologic changes and renal outcome in patients with type 2 diabetes mellitus (T2DM). METHODS A total of 396 patients with T2DM and biopsy-proven DN who received f...

The aim of this study is to determine the value of surgical staging for the two histologic types (expansile or infiltrative) of apparent stage I mucinous ovarian carcinoma. We retrospectively analyzed patients treated from 1976 and 2016 for apparent macroscopic stage I ovarian mucinous carcinoma. Extra-ovarian disease and tumors that metastasized to the ovaries were excluded. Two expert patholo...
