Cervical polyps can be removed using ring forceps. They can also be removed by tying surgical string around the polyp and cutting it off. The remaining base of the polyp can then be removed using a laser or by cauterisation. If the polyp is infected, an antibiotic may be prescribed.
Usually no treatment is indicated for clinically asymptomatic cervical ectropions. Hormonal therapy may be indicated for symptomatic erosion. If it becomes troublesome to the patient, it can be treated by discontinuing oral contraceptives, cryotherapy treatment, or by using ablation treatment under local anaesthetic. Ablation involves using a preheated probe (100 °C) to destroy 3–4 mm of the epithelium. In post-partum erosion, observation and re-examination are necessary for 3 months after labour.
Most polyps are benign and do not need to be removed. Polyps larger than 1 cm with co-occurring gallstones occurring in people over the age of 50 may have the gallbladder removed (cholecystectomy), especially if the polyps are several or appear malignant. Laparoscopic surgery is an option for small or solitary polyps.
Wide, radical, complete surgical excision is the treatment of choice, with free surgical margins to achieve the best outcome and lowest chance of recurrence. Radiation is only used for palliation. In general, there is a good prognosis, although approximately 50% of patients die from disease within 3–10 years of presentation.
Since this lesion is usually a complication of long standing otitis media, it is important to use an appropriate antibiotic therapy regimen. If the patient fails first line antibiotics, then second-line therapies should be employed, especially after appropriate culture and sensitivity testing. Surgery may be required if there is extension into the mastoid bone, or if a concurrent cholesteatoma is identified during surgery or biopsy. In general, patients have an excellent outcome after appropriate therapy.
The treatment is dependent on the stage. As the prognosis of this tumour is usually good, fertility sparing approaches (conization, cervicectomy) may be viable treatment options.
Treatment for CIN 1, which is mild dysplasia, is not recommended if it lasts fewer than 2 years. Usually when a biopsy detects CIN 1 the woman has an HPV infection which may clear on its own within 12 months, and thus it is instead followed for later testing rather than treated.
Treatment for higher grade CIN involves removal or destruction of the neoplastic cervical cells by cryocautery, electrocautery, laser cautery, loop electrical excision procedure (LEEP), or cervical conization. Therapeutic vaccines are currently undergoing clinical trials. The lifetime recurrence rate of CIN is about 20%, but it isn't clear what proportion of these cases are new infections rather than recurrences of the original infection.
Surgical treatment of CIN lesions is associated with an increased risk of infertility or subfertility, with an odds ratio of approximately 2 according to a case-control study.
The treatment of CIN during pregnancy increases the risk of premature birth.
Treatment of endometrial hyperplasia is individualized, and may include hormonal therapy, such as cyclic or continuous progestin therapy, or hysterectomy.
99% of cervical polyps will remain benign and 1% will at some point show neoplastic change. Cervical polyps are unlikely to regrow.
Treatment of cervical stenosis involves opening or widening the cervical canal. The condition may improve on its own following the vaginal delivery of a baby.
Cervical canal widening can be termporarily achieved by the insertion of dilators into the cervix. If the stenosis is caused by scar tissue, a laser treatment can be used to vaporize the scarring.
Finally, the surgical enlargement of the cervical canal can be performed by hysteroscopic shaving of the cervical tissue.
Treatment may involve surgery, which is currently the only recommended intervention. Surgery should include the removal of even small nodules, to prevent the recurrence of the scrotal calcinosis.
The main treatment modalities are surgery, embolization and radiotherapy.
Although surgery is the treatment of choice, it must be preceded by imaging studies to exclude an intracranial connection. Potential complications include meningitis and a cerebrospinal fluid leak. Recurrences or more correctly persistence may be seen in up to 30% of patients if not completely excised.
Carcinoma "in situ" is, by definition, a localized phenomenon, with no potential for metastasis unless it progresses into cancer. Therefore, its removal eliminates the risk of subsequent progression into a life-threatening condition.
Some forms of CIS (e.g., colon polyps and polypoid tumours of the bladder) can be removed using an endoscope, without conventional surgical resection. Dysplasia of the uterine cervix is removed by excision (cutting it out) or by burning with a laser. Bowen's disease of the skin is removed by excision. Other forms require major surgery, the best known being intraductal carcinoma of the breast (also treated with radiotherapy). One of the most dangerous forms of CIS is the "pneumonic form" of BAC of the lung, which can require extensive surgical removal of large parts of the lung. When too large, it often cannot be completely removed, with eventual disease progression and death of the patient.
Atypical polypoid adenomyoma, abbreviated APA, is a rare uncommon benign tumour of the uterus.
The disease used to be uniformly fatal, with a 5-year survival rate between 10 and 35%. As a result, treatment was radical surgery. New multidrug chemotherapy regimens with or without radiation therapy are now used in combination with less radical surgery with good results, although outcome data are not yet available.
In obstetrics and gynecology contexts, it is a form of adenomyosis that forms a mass or growth around the tissue of the inner uterus.
Most cases of adenomyosis are non-symptomatic. However, it may present with dysmenorrhea and pelvic pain. In the case of juvenile cystic adenomyoma, laparoscopic enucleation results in a statistically and clinically significant reduction in dysmenorrhea, ease in any chronic pelvic pain, and low risk of recurrence.
APAs are characterized by glands with abnormal shapes that: (1) often have squamous metaplasia, and (2) are surrounded by benign smooth muscle. Nuclear atypia, if present, is mild.
The microscopic differential diagnosis includes endometrial carcinoma and endocervical adenocarcinoma.
Gallbladder polyps are growths or lesions resembling growths (polypoid lesions) in the wall of the gallbladder. True polyps are abnormal accumulations of mucous membrane tissue that would normally be shed by the body. The main types of polypoid growths of the gallbladder include cholesterol polyp/cholesterosis, cholesterosis with fibrous dysplasia of gallbladder, adenomyomatosis, hyperplastic cholecystosis, and adenocarcinoma.
Adenomyoma is a tumor ("-oma") including components derived from glands ("adeno-") and muscle ("-my-"). It is a type of complex and mixed tumor.
The first line of therapy after diagnosis typically involves the administration of the combined oral contraceptive pill, medroxyprogesterone acetate or a gonadotropin-releasing hormone agonist to suppress menstruation and thereby relieve pain. Surgically, cervical agenesis has historically been treated through hysterectomy (removal of the uterus) to relieve symptoms caused by hematocolpos (the accumulation of menstrual fluid in the vagina). Other surgical methods of management involve the creation of an anastomotic connection between the uterus and vagina by neovaginoplasty or recanalization of the cervix. Outcomes in these cases are generally poor, since the natural functions of the cervix—such as mucus production and providing a barrier against ascending infection—cannot be replicated. Furthermore, the success rate of uterovaginal anastomosis is less than 50% and most patients require multiple surgeries while many develop cervical stenotis. Despite this, several pregnancies have been reported in women with cervical agenesis who underwent surgical treatment.
These lesions generally do not require treatment. If they are cosmetically unappealing or are subject to bleeding angiomas may be removed by electrocautery, a process of destroying the tissue by use of a small probe with an electric current running through it. Removal may cause scarring. More recently pulsed dye laser or intense pulsed light (IPL) treatment has also been used.
Future treatment based on a locally acting inhibitor of MEK1 and Cyclin E1 could possibly be an option. A natural MEK1 inhibitor is myricetin
Ceruminous adenocarcinoma is a malignant neoplasm derived from ceruminous glands of the external auditory canal. This tumor is rare, with several names used in the past. Synonyms have included cylindroma, ceruminoma, ceruminous adenocarcinoma, not otherwise specified (NOS), ceruminous adenoid cystic carcinoma (ACC), and ceruminous mucoepidermoid carcinoma.
Villoglandular adenocarcinoma of the cervix, also villoglandular papillary adenocarcinoma, papillary villoglandular adenocarcinoma and well-differentiated villoglandular adenocarcinoma, abbreviated VGA, is a rare type of cervical cancer that, in relation to other cervical cancers, is typically found in younger women and has a better prognosis.
A similar lesion, "villoglandular adenocarcinoma of the endometrium", may arise from the inner lining of the uterus, the endometrium.
Induction chemotherapy is the treatment adapted for shrinking the tonsil tumor. It is given prior to other treatments, hence, the term induction. After the therapy is completed, the patient is asked to rest and is evaluated over a period of time. Then the patient is given chemo-radiation therapy (a combination of chemotherapy and radiation) to completely destroy the tumor cells.
