* Context.--The fallopian tube is a common specimen in a pathology laboratory. It may be examined either alone as a salpingectomy or tubal ligation specimen, or as part of a more complex specimen from a hysterectomy and/or oophorectomy operation. Although the common histologic findings in the fallopian tube have been described previously, to our knowledge no study has documented the frequency of histologic changes in fallopian tubes removed for all reasons or associations with clinical history. Design.--Hematoxylin-eosin-stained slides from 287 fallopian tube specimens were reviewed without knowledge of the clinical history. Three categories and associated subcategories of histologic findings were identified (listed in descending order of frequency): stromal and architectural alterations (fibrosis, intramuscular edema, cellular luminal contents, inclusion cysts, Walthard nests, pigmentosis tubae, Wolffian duct remnants, decidualized stroma, endosalpingiosis, and metastatic carcinoma), epithelial characteristics (cytologic atypia, vacuolization, metaplasia, and tufting), and inflammatory changes (intramuscular mast cells, plasma cells, neutrophils, and lymphoid follicles). Histologic findings were correlated with clinical history, surgery type, and age. Results.--Intramuscular edema was identified in 12.5% of specimens, most frequently in postpartum women. Plical fibrosis (35.5% of specimens), epithelial atypia (7.3%), epithelial vacuolization (6.6%), and epithelial tufting/stratification (3.5%) correlated with increased patient age. Inflammatory cells were relatively common; 69% of specimens contained intramuscular mast cells, 19.9% had stromal plasma cells, 10.5% had neutrophils, and 2.1% had lymphoid follicles. Conclusions.--This study provides data that may be valuable for surgical pathologists involved in identifying and characterizing common histologic changes in surgically removed fallopian tubes., The histologic findings in fallopian tubes have been described only sporadically in the literature. As this is a common specimen in the general surgical pathology laboratory, knowledge of the general [...]

* Context.--Recognizing the difficulty in applying the concept of critical values to anatomic pathology diagnoses, the College of American Pathologists and the Association of Directors of Anatomic and Surgical Pathology have chosen to reevaluate the concept of critical diagnoses. Objective.--To promote effective communication of urgent and significant, unexpected diagnoses in surgical pathology and cytology. Design.--A comprehensive literature search was conducted and reviewed by an expert panel. Results.--A policy of effective communication of important results in surgical pathology and cytology is desirable to enhance patient safety and to address multiple regulatory requirements. Conclusions.--Each institution should create its own policy regarding urgent diagnoses and significant, unexpected diagnoses in anatomic pathology. This policy should be separate from critical results or panic-value policies in clinical pathology, with the expectation of a different time frame for communication. Urgent diagnosis is defined as a medical condition that, in most cases, should be addressed as soon as possible. Significant, unexpected diagnosis is defined as a medical condition that is clinically unusual or unforeseen and should be addressed at some point in the patient's course.

(Arch Pathol Lab Med. 2012; 136:148-154; doi: 10.5858/arpa.2011-0400-SA), To comply with regulatory and accreditation requirements, most institutions have adopted policies for communicating critical test results from clinical pathology laboratories, radiology departments, and other testing areas, such as the [...]
