What does polypoid cystitis mean?
Polypoid cystitis is a rare lesion of the bladder mucosa characterized by inflammation, epithelial proliferation, and development of a polypoid mass without histopathologic evidence of neoplasm. Polypoid cystitis is frequently found in patients with indwelling catheters.
How is polypoid cystitis treated?
Conclusion: Polypoid cystitis with ureteral obstruction needs to be considered in differentials of a bladder tumor, and management may include a combination of endoscopic resection, ureteral stenting, and in resistant cases oral steroids can be considered to aid resolution of inflammation in the absence of infection.
Is polypoid cystitis cancerous?
Polypoid cystitis is a non-cancerous and reversible condition caused by chronic (long-standing) inflammation on the inside of the bladder.
What causes polypoid cystitis?
There are no definitive known causes of polypoid cystitis, but they are thought to be caused by: Chronic urinary tract inflammation. Frequent or recurrent bladder or urinary tract infection. Chronic bladder or urinary tract infections.
What is polypoid mass?
Any discrete lesion protruding into the lumen of gastrointestinal (GI) tract appeared at endoscopy is called as “polypoid lesion”[3]. However, a polyp is defined as a proliferative or neoplastic lesion of gastrointestinal mucosal layer[3].
What is papillary cystitis?
Polypoid cystitis and its more chronic phase papillary cystitis, which results as a reaction to injury to the bladder mucosa, is a benign lesion mimicking various papillary urothelial neoplasms.
Can bladder tumors benign?
Bladder tumors are abnormal growths that occur in the bladder. If the tumor is benign, it’s noncancerous and won’t spread to other parts of your body. This is in contrast to a tumor that’s malignant, which means it’s cancerous. There are several types of benign tumors that can develop within the bladder.
What does polypoid endometrium mean?
Introduction. Polypoid adenomyoma of the uterus is an endometrial polyp in which the stromal component is made up of smooth muscle [1]. These are benign tumors and account for 1.3% of all endometrial polyps. Polypoid adenomyomas are of mixed epithelial and mesenchymal origin [2].
What is a polypoid tumor?
Polypoid tumors of the bowel arise as fiat plaques of tissue which spread circumferentially (Fig. 1, A). The more rapidly infiltrating tumors soon invade the deeper layers of the bowel wall and encircle the bowel until the typical “napkin ring” carcinoma is produced.
What causes Autopolyploidy?
Autopolyploidization can occur when the pairs of homologous chromosomes have not separated into different nuclei during meiosis. The resulting gametes will be diploid rather than haploid.
What is polypoid and papillary cystitis?
Polypoid and papillary cystitis are described as a benign lesion in the mucosal lining of the bladder. The most common cause of polypoid and papillary cystitis is urinary catheterization; however, it can occur randomly as well. This type of cystitis is often similar to findings of bladder cancer.
What is polypoid urethritis?
Polypoid cystitis and its more chronic phase papillary cystitis, which results as a reaction to injury to the bladder mucosa, is a benign lesion mimicking various papillary urothelial neoplasms. Analogous lesions occur throughout the urothelial tract and are referred to as polypoid urethritis, polypoid ureteritis,
Can polypoid and papillary cystitis mimic bladder cancer?
Polypoid and papillary cystitis can often mimic bladder cancer so a proper diagnosis is important. The first line of treatment for polypoid and papillary cystitis is to remove the irritant (urinary catheter), followed by antibiotics. Other times no treatment is needed, but surgical removal of the lesion may be done if symptoms are severe.
What causes multiple benign cysts in the bladder?
A rare condition known as cystitis cystica results in the formation of multiple benign cysts in the bladder. Cystitis cystica is more common in women. It’s thought to be the result of chronic irritation in the urinary tract causing inflammation in the bladder.
