Histologic Criteria for Adrenocortical Proliferative Lesions

Histologic criteria for adrenocortical proliferative lesions: value of mitotic figure variability.

This study compared 3 systems and a newly designed stepwise discriminant diagnostic system (SDDS) to assess accuracy, reproducibility, and reliability in adrenocortical nodular hyperplasia (ACNH; n = 82), adenoma (ACA; n = 78), and carcinoma (ACC; n = 32) (diagnoses according to World Health Organization criteria; median follow-up, 135 months). In cross-validations, we studied cortex appearance...

Diagnostic criteria for proliferative hepatic lesions in brown bullhead Ameiurus nebulosus.

Brown bullhead Ameiurus nebulosus is used as indicator species for contaminant effects at areas of concern (AOC) in the Great Lakes and other areas. One of the beneficial use impairments at numerous AOC is 'fish tumors and other deformities'. An impairment occurs when the prevalence of fish tumors and other deformities exceeds those at unimpacted or control sites or when survey data confirm the...

Proliferative Lesions Without Atypia

Cancer Control 321 determine the inherent risk they presented. Over 10,000 specimens were divided into three groups: nonproliferative lesions,proliferative lesions without atypia, and proliferative lesions with atypia. Their findings suggested a 1.9 times greater risk for proliferative lesions without atypia and 5.3 times greater risk for proliferative lesions with atypia.1,2 Subsequent case-co...

Proliferative Lesions and Neoplasia

I. Causative Agent and Disease Reports of abnormal proliferation of tissues in marine decapod crustaceans have been extremely rare. There have been less than a dozen cases in the literature of which only four have shown convincing evidence of cancer. Cancers or neoplasms are growths of abnormal cells that proliferate uncontrollably and have no useful function as opposed to cells that are normal...
