Auxiliary findings like
reactive changes, infectious organisms are listed succeeding.
ASC-US diagnosis determines cellular abnormalities more prominent than those attributable to
reactive changes, but that do not meet the requirements for a squamous intraepithelial lesion (SIL) (2).
(3,4) This occurs by the presence of an in situ component, fibrotic stroma,
reactive changes of a biopsy site, or particular features of the tumor (eg, carcinomas with lobular features).
There were also
reactive changes and mild dysplasia (lowgrade dysplasia) in the mucosal epithelium surrounding the ulcer (Figure 1, 2).
It covers sampling and preparation technique, fixation, and staining; principles of interpretation; the normal breast; the cytology of inflammatory and
reactive changes; the epidemiology, histological features, and cytology of cystic, epithelial proliferative, and fibroepithelial lesions, invasive carcinoma, and other breast neoplasms; assessment of the lymph node status; and ancillary techniques.
True vision goes beyond
reactive changes to meet shifting expectations.
Reactive changes due to underlying CKD and inflammation were the most frequent findings in the BM of the patients.
The most frequent finding on histopathological analysis was
reactive changes (27.5%) followed by chronic granulomatous inflammation (22.5%), atypical mononuclear infiltrate (10%), aplastic anemia, hypocellular marrow and visceral leishmaniasis (7.5% each).
"Recent studies have supported the hypothesis that astrocytes have a beneficial role contributing to amyloid-beta clearance, but also that excess amyloid-beta can lead to oxidative stress and damage, and as a consequence to reduced astrocyte functionality, leading to
reactive changes and decreased neuronal support, and thereby contributing to neurodegeneration."
US and cystoscopy after 3 months showed marked regression and biopsies showed nonspecific
reactive changes. At removal of the JJ catheter after 7 months, the bladder looked near normal at cystoscopy.
When smear microscopy identified changes in the cells it was difficult to differentiate between
reactive changes and epithelial dysplasia (ASC-US); these changes were more often in the background of the inflammatory process (Figure 1).
In addition to VIN 1 not having any progression to malignancy, it is a diagnosis that is difficult to reproduce and may, at times, reflect
reactive changes or other dermatosis.
