progressive growth that usually does not regress. Acollaretteof epithelium is defined as epithelium at the edge of a lesion, sometimes part of hyperplastic adnexal structures, which tend to bow inwardly and clutch alterations of thedermis. Examples of lesions that often have collarettes include liche...
with the capacity to undergo mitosis. Tissues such as liver or bone marrow are typical examples of tissues that readily undergo such reparative process. The hyperplastic response may result in resolution of the lesion if conditions are appropriate for orderly regeneration—e.g., intact stromal ...

Glandular hyperplasia occurs in the breast during pregnancy. 9 Neoplas...
Examples of BPH procedures are: Transurethral resection of the prostate, in which the doctor uses a scope and cuts out pieces of the gland with a wire loop. Transurethral incision of the prostate, in which the doctor makes a few small cuts in the prostate to reduce the gland's pressure on...
Three anthropomorphic phantoms were created representing examples of bone anatomy of a normal patient and two patients positive for UCH, based on data from clinical CT studies (Fig. 1). Bone structures were segmented in 3D Slicer (v4.11.20210226; www.slicer.org). A shell of 2 mm thickness ...
through the penis into the urethra (tube that carries urine out of the bladder) where it passes through the prostate gland, in order to physically widen the urethra. Examples are TURP, TUMT, TUNA, and transurethral laser delivery systems.See Frequently Asked Questions at the end for more ...

From a clinical standpoint, there are many diseases in which the dysregulation of the thymus is implicated. Six such examples of thymic-related diseases are listed below: 1. DiGeorge syndromeis anautosomal dominantcongenital disorder caused by a partial deletion ofchromosome 22. The adverse effects...
Although not all neoplasms exhibit a preneoplastic change recognizable by the pathologist, in those instances in which presumptive alterations are observed, their occurrence documents that there is a response to tissue insult. Examples of presumptive preneoplastic lesions are presented in Table 3. In ...
It is unclear what issues are under dispute, according to these au- thors, as both referenced papers provided clear examples of lobular heterogeneity in CD8+ cell infiltration and HLA MHC Class I hyperexpression, respectively. Furthermore, lobular heterogeneity has been extensively reported in type ...
