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 support, adequate vascular supply, and a ...
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, that tends to bow inwardly and clutch alterations of the dermis. Examples of lesions that often have collarettes include lic...
Hypertrophy refers to the enlargement of cells in response to increased workload or stimulation. It is a process where individual cells increase in size, leading to the growth of the affected tissue or organ. This can occur in various organs, such as muscles, heart, and kidneys, to meet inc...
Hyperplasia:An increase in the number of normal cells in a tissue or an organ.Hyperplasiacan represent a precancerous condition.
Examples Benign prostatic hyperplasia, skin hyperplasia Cancer, benign tumors like lipomas 15 Compare with Definitions Hyperplasia An increase in the number of cells in an organ or tissue, usually in response to a specific demand. Glandular hyperplasia occurs in the breast during pregnancy. 9 Neoplas...

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 ...

Examples of presumptive preneoplastic lesions are presented inTable 3. In those experimental models of carcinogenesis in which preneoplasia is observed, it precedes the occurrence of benign neoplasia. An important feature of preneoplastic lesions is their propensity for reversibility. In some instances,...
