Columnar cell lesions of the breast: mammographic findings with histopathologic correlation.

Because of advances in mammography and a concomitant rise in the number of breast biopsies being performed for mammographically detected abnormalities, increasing numbers of columnar cell lesions (CCLs) are being described by pathologists. However, these lesions can be challenging to manage, since their classification has changed over time and only limited research has been conducted regarding their clinical significance. CCLs may be characterized by a single layer of columnar cells (columnar cell change [CCC]), multiple layers with stratification and apical tufting (columnar cell hyperplasia [CCH]), or monomorphic cells with cytologic atypia (flat epithelial atypia [FEA]).

The medicolegal aspect of error in pathology: a search of jury verdicts and settlements.

Context: Identifying medical errors is a topic of current attention. Among the various approaches is the study of medical malpractice cases.

Objective: To identify the most common medical errors involving the practice of pathology from a medicolegal perspective by analysis of published jury verdict and settlement reports.
