Bladder tumors are classified by their appearance under the microscope, and by their cell type of origin. Over 90% of bladder tumors arise from the cells that form the bladder's inner lining, called urothelial cells or transitional cells; the tumor is then classified as urothelial cancer or transitional cell cancer.
In cases of a lining 3 mm or less and clear endometrial fluid, endometrial biopsy was not regarded to be necessary, but endocervical curettage to rule out endocervical cancer was recommended. [25] Hematometra, which is accumulation of blood within the uterus. [26] Prolapse of the uterus; Carcinoma of the cervix – malignant neoplasm
It accounts for 95% of bladder cancer cases and bladder cancer is in the top 10 most common malignancy disease in the world and is associated with approximately 200,000 deaths per year in the US. [2] [3] It is the second most common type of kidney cancer, but accounts for only five to 10 percent of all primary renal malignant tumors. [4]
There are a number of indications for obtaining an endometrial biopsy from a non-pregnant woman: [citation needed]. Women with chronic anovulation such as the polycystic ovary syndrome are at increased risk for endometrial problems and an endometrial biopsy may be useful to assess their lining specifically to rule out endometrial hyperplasia or cancer.
The Tao brush is a medical instrument used to perform an alternative method of endometrial biopsy, for the purpose of detecting endometrial cancer. The traditional method of endometrial biopsies uses a specialized catheter (the Pipelle) to suction away a portion of the uterine lining. The Tao brush method instead uses a small, flexible brush to ...
The myometrium is located between the endometrium (the inner layer of the uterine wall) and the serosa or perimetrium (the outer uterine layer).. The inner one-third of the myometrium (termed the junctional or sub-endometrial layer) appears to be derived from the Müllerian duct, while the outer, more predominant layer of the myometrium appears to originate from non-Müllerian tissue and is ...
Sarcoma botryoides or botryoid sarcoma [1] is a subtype of embryonal rhabdomyosarcoma, that can be observed in the walls of hollow, mucosa lined structures such as the nasopharynx, common bile duct, urinary bladder of infants and young children or the vagina in females, typically younger than age 8.
Transitional cell carcinoma is the most common type of bladder cancer and cancer of the ureter, urethra, renal pelvis, the ureters, the bladder, and parts of the urethra and urachus. [ 1 ] [ 2 ] It originates from tissue lining the inner surface of these hollow organs - transitional epithelium .
