Fibroepithelial polyps.

Fibroepithelial polyps are rare ureteral mucosal formations that can lead to obstruction. Similar changes can be detected at any level of the urinary tract, but in terms of the frequency of occurrence of fibroepithelial polyps, the ureters are in the first place, followed by the urethra, pelvis, bladder. In men, the predominant localization is the ureters, bladder and urethra, in women - the renal pelvis. The left ureter and pelvis are more often affected. The majority of patients (80%) are younger than 10 years old.

The etiology and pathogenesis are not precisely established. They are considered as congenital pathology, inflammation, hamartomas or tumors. More often their development is associated with chronic inflammation (an analogue is polypous cystitis with stromal fibrosis).
The histogenesis of fibroepithelial polyps is poorly understood. The presence of smooth muscle cells in some polyps speaks in favor of hamartoma more than in favor of a true tumor.

Macroscopically, it looks like a knot with a smooth or uneven surface, of different sizes (from several millimeters to several centimeters). Microscopically transitional polyp epithelium can be normal or hyperplastic. The stroma contains collagen fibers, various numbers of small blood vessels, and sometimes smooth muscle cells. Cellular inflammatory infiltration, focal hyalinosis and calcification can be observed.

The prognosis is favorable, malignancy is rare.

Fibroepithelial polyps.

  1. Polyps
    Polyps of the cervix uteri are growths on the cervix (often in the walls of the cervical canal) in the form of a leg with a connective tissue skeleton (rod) covered with a multilayer flat or cylindrical epithelium with glandular structures in the thickness. There are simple (formed glandular or glandular-fibrous formations without proliferative changes) and adenomatous (formations with
  2. Polyps of the nose
    Polyps of the nose is one of the complications of year-round allergic rhinitis. Usually they are localized on the middle nasal concha, around the openings of the maxillary sinuses and the ethmoid labyrinth. Polyps are observed in both allergic and infectious rhinitis. Polyps that occur with allergic rhinitis look like whitish or gray, shiny, gelatinous formations. Polyps in chronic
  3. Cervical Canal Polyps
    Seldom give significant bleeding, more often it is minor bleeding. Decidual polyp - the growth of decidual tissue, and its excess descends into the cervical canal. Such a polyp most often disappears by itself, or it can be removed by carefully unscrewing. A bleeding polyp should be removed, but without curettage of the uterine cavity, with hemostatic therapy, and preserving pregnancy
  4. Endometrial polyps
    Definition of a concept. Endometrial polyps are the growths of individual sections of the mucous membrane of the uterine body (together with the underlying stroma). The term "polyp" has existed in medicine for a long time. For the first time to describe such growths, this term was used in the middle of the XVIII century. However, already in the writings of Hippocrates, one can find mention of polyps as a cause of infertility. Frequency. Literature Data
  5. Endometrial polyps
    Another cause of reproductive system dysfunctions can be endometrial polyps that prevent embryo implantation and are a common cause of menstrual cycle changes. An endometrial polyp occurs as a result of focal growth of the uterine mucosa (endometrium). This formation grows from the wall of the uterus into its cavity and sometimes through the cervical canal reaches
  6. Endometrial polyps
    Endometrial polyps develop due to proliferation of the glands of the basal layer of the endometrium on the leg, consisting of fibrous and smooth muscle tissue. Endometrial polyps are focal endometrial hyperplasia. Due to the fact that in their structure there is stromal tissue (leg), it should not be identified with the polypoid form of glandular-cystic endometrial hyperplasia, in connection with which the term
  7. Non-tumor polyps
    The vast majority of such formations that occur, in particular, in the colon, are sporadic, and the frequency of their development increases as a person ages. Non-tumor polyps (mostly hyperplastic) make up about 90% of all colon epithelial polyps and are found in more than 50% of people 60 years of age or older. Inflammatory (pseudo-) polyps,

Glandular and glandular-villous (adenomas and adenopapillomas); 2. Hyperplate (miliary). 3. Cystogranulating. 4. Rare non-epithelial polypoid formations. II group.
  9. P. POLYPES AND Tumors of the Large Intestine
    1. Benign polyps, polyposis and tumors. The etiology and pathogenesis, as well as tumors, in general, have not yet been sufficiently studied. Benign tumors (according to WHO, Geneva, 1981) are divided into three groups: 1). epithelial; 2). carpinoid; 3). non-epithelial tumors. Among the epithelial tumors of the colon, which make up the vast majority of all its tumors, distinguish

  11. Polyps, cysts, and other benign changes in the cervix, vagina, and vulva
    This section describes polyps recognized by colposcopic examination, polypous changes, various cysts on the cervix, in the vagina and vulva. On the cervix, retention mucous cysts are most often formed. The mechanism of their formation is described in section 4.1.3. When the ectopia overlaps the squamous epithelium, mucus retention occurs and retention cysts form. Rarely

    formed as a result of inflammatory-reactive hyperplasia of the mucosa. Tumors are fibroepithelial, less commonly fibroids, fibroids, neuromas, angiomas, lipomas, hemangiomas. Polyps - conditionally benign tumors, are single or multiple formations located mainly in the antrum

According to pathological signs: polypous gastritis; single and multiple polyps (benign, malignant, polypous cancers from polyps); multiple polyps of the gastrointestinal tract. II. According to the clinical course: asymptomatic form; gastritis anemic; complicated form (bleeding polyps, polyp prolapse in

    Epithelial tumors make up the majority of intestinal neoplasms. Moreover, the colon, including the rectum, is one of the most common organ localizations of primary tumors.
