Histologic Grading of Noninvasive Papillary Urothelial Neoplasms
European Urology, 2007In 1998, a revised system of classifying noninvasive papillary urothelial neoplasms of the urinary bladder was proposed and subsequently formally adopted by the World Health Organization (WHO). The introduction of this new system was justified as being potentially superior on a number of levels to the 1973 WHO classification system that it replaced ...

High grade neuroendocrine neoplasm of the antrum and orbit
Survey of Ophthalmology, 2015Neuroendocrine malignancies-tumors characterized by the production of dense-core secretory granules-are most often encountered in the lungs and can also be found in extrapulmonary sites. Our patient had a primary neuroendocrine tumor of the antrum with an elusive cell of origin that secondarily invaded the inferior orbit. In the sinuses, neuroendocrine

Transformation in Low-grade B-cell Neoplasms
Surgical Pathology Clinics, 2016Low-grade B-cell leukemias/lymphomas are a diverse group of indolent lymphoproliferative disorders that are typically characterized by good patient outcomes and long life expectancies. A subset of cases, however, undergo histologic transformation to a higher-grade neoplasm, a transition associated with a more aggressive clinical course and poor ...

Endocrine Pathology, 2018
Grade 3 neuroendocrine tumor (NET G3) is a rare new entity that has recently been introduced in the classification of neuroendocrine neoplasms of the pancreas. It is a well-differentiated form, with a high proliferative activity (Ki67 > 20%), and it represents a category whose prognosis is intermediate between NET G2 and poorly differentiated ...

Reproducibility and reliability of tumor grading in urological neoplasms
World Journal of Urology, 2007Histopathologic tumor grading reflects the degree of differentiation of a given tumor and for most urological tumors grading is an important factor in predicting their biological aggressiveness. Consequently, the clinical management of tumor patients is often strongly influenced by the tumor grade, provided by pathologists.

[Grading of head and neck neoplasms].
Der Pathologe, 2017Tumors of the head and neck form a heterogeneous group of benign and malignant neoplasms with significant differences in biological behavior and therapeutic strategies. Squamous cell carcinomas (SCC) of the larynx, pharynx and oral cavity represent the most frequent and, thus, clinically most important malignant neoplasms in this anatomical region ...

Mutation profile of high‐grade appendiceal mucinous neoplasm
Histopathology, 2019AimsHigh‐grade appendiceal mucinous neoplasm (HAMN) was recently proposed as a disease entity histologically analogous to low‐grade appendiceal mucinous neoplasm (LAMN), but characterised by high‐grade cytological atypia. The pathogenesis and clinical features of HAMN have not been fully elucidated.Methods and resultsNine cases of HAMN, eight LAMN, 10 ...
