Abstract

This article aims to report a rare case of a 38 years old Para 2 who was referred to the outpatient clinic of Vikash Multispecialty Hospital as a case of grade 3 uterovaginal prolapse with complaint of something coming out per vagina since 12 years. She also complained of heavy bleeding during menstruation, not responding to medical management since 2 years. Clinical and imaging studies lead to the diagnosis of anterior vaginal cyst, intramural fibroid and cervical polyp. After detailed counseling of the risks and benefits of surgical excision of the cyst with or without removal of uterus, she opted for removal of vaginal cyst and vaginal hysterectomy as she was tired of the medical management and had to undergo blood transfusion twice due to heavy menstrual bleeding. She had an uneventful postoperative period and was discharged in good condition on the third day. This case stresses on the importance of right diagnosis and proper management of the masses coming out of vagina as not everything which comes out of vagina is prolapse. Hesitancy in seeking medical care and lack of proper medical facilities, especially in rural areas in underdeveloped and developing countries, are among the major reasons these cases are unreported in medical literature.

1. Introduction
Vaginal cysts are rare, benign, predominantly cystic lesions, commonly of the anterior vaginal wall. They typically present in 3rd or 4th decade of life and also seen in children and postmenopausal women . Vaginal cysts are usually small (0.5-2 cm in diameter), solitary and asymptomatic; however they can increase in size and are often misdiagnosed as anterior vaginal prolapse. Therefore, complete surgical vaginal excision of the symptomatic vaginal lesion is feasible and constitutes a good management option .
2. Case Report
Mrs A, 38 years old, Para 2 was referred to the outpatient clinic of Vikash Multispecialty Hospital as a case of grade 3 uterovaginal prolapse with complaint of something coming out per vagina since 12 years and heavy bleeding during menstruation, not responding to medical management since 2 years. She had developed anemia due to heavy menstrual bleeding and had to undergo blood transfuison twice.
On examination, patient was pale. Abdomen was soft with no palpable masses.
Perineal inspection appeared as grade 3 anterior vaginal wall prolapse but close examination after urethral catherization showed minimal cystocoele with large anterior vaginal cyst (Figure 1). The cyst was about 8 x 7 cm in size. It appeared extending from the upper part of right lateral fornix with the lower edge at the cervicovaginal junction.
Per speculum examination showed a fleshy structure protruding through the cervical os.
Uterus was enlarged to 8 weeks size on bimanual examination with a firm growth protruding through the os. Growth was felt free from the endocervical canal and upper edge was not reached.
Ultrasound showed enlarged uterus with a 2.5 x 1.4 cm sized well defined hypoechoic mass lesion seen in the anterior wall of uterus and another well defined hyper echoic lesion measuring 3 x 2.4 cm in the cervical region with well defined vascular pedicle but no details was mentioned about the vaginal cyst.
Contrast CT scan was done which showed a fluid filled globular structure of size 7.9 x 4.8 x 3.3 cm projecting outside the vulva from the vaginal canal. There was no evidence of filling of contrast in the delayed phases within the cystic lesion protruding from the vulva. Cervix and uterus were stretched inferiorly till just above the introitus.
The patient was counseled about the findings.
She wanted definitive management of her clinical condition of heavy menstrual bleeding and vaginal cyst.
After detailed counseling of the risks and benefits, she opted for removal of vaginal cyst and vaginal hysterectomy.
She received 1 unit of blood preoperatively in view of anemia.
Figure 1. Anterior vaginal cyst.
Small incision was given in the lower part of the vaginal cyst and extended superiorly. The cyst got ruptured during enucleation and mucinous brownish fluid was drained. Cyst wall was dissected and redundant vaginal walls were excised. Cavity was closed with Vicryl no. 1. Removal of uterus and cervix was done by vaginal route. Bilateral tubes and ovaries were preserved. Vaginal vault was closed with Vicryl no 1 after haemostasis.
Cut Specimen was noted to have 4 x 4 cm intramural fibroid with sub mucosal component which was protruding through the os.
Histopathogical examination of the specimen showed vaginal cyst lined by ciliated columnar epithelium and was labeled as Mullerian cyst. Full report of the specimen included Chronic papillary cervicitis, Endometrial polyp, Leiomyoma no signs of atypia or malignancy.
Her postoperative stay was uneventful and she was discharged home on the third postoperative day.
3. Discussion
Vaginal cysts have an estimated prevalence of 0.5-1%. Being rare, these pose as a diagnostic challenge upon presentation
Their origin may be Mullerian (paramesonephric), Wolffian (mesonephric), squamous (traumatic), or urogenital. The cysts are usually small, ranging from 0.1 to 2 cm in diameter, although they may measure >4 cm. The differential diagnoses of a cyst in the lower female genital tract include Mullerian cyst, inclusion ¨ cyst, mesonephric cyst (Gartner’s duct), Bartholin gland cyst, urethrocele, urethral diverticulum, Skene’s duct cyst, pelvic organ prolapse, hematocolpos, and a myxomatous tumour . Simple mesonephric (Gartner’s) or paramesonephric (Mullerian) cysts may occur at especially high levels near the fornices.
40% of the cystic vaginal masses of embryologic origin are Müllerian cysts Gartner’s duct cysts are less common than Mullerian ¨ cysts, comprising approximately 10% of benign vaginal cysts.
The prevalence might be under reported due to hesitancy in seeking medical care especially in rural areas in developing countries. The above mentionedcase finally presented at 38 years of age with her chief complaint of heavy menstrual bleeding though she was suffering for the past 12 years with dyspareunia, difficulty in walkingdue to the vaginal cyst.
Müllerian cysts arise from persistence of pseudostratified columnar epithelium during its replacement with squamous epithelium. This epithelium can persist anywhere in the vagina but Müllerian cysts are generally located anterolaterally near the vaginal fornix . Their size varies generally between 1cm to 7cm but it can sometimes be much bigger. 40% of the cystic vaginal masses of embryologic origin are Müllerian cysts . Dyspareunia, pelvic pain, pressure, bulging mass and urinary incontinence or obstruction are the most frequent presenting symptoms associated with vaginal cyst .
Mullerian and Gartner cysts are benign tumors, but malignancy must be considered. Lee reported adenocarcinoma arising in a Mullerian vaginal cyst . In literature there are very rare reported cases of malignant vaginal cysts, but even with an asymptomatic and small cyst this eventuality should be considered.
Cysts should be characterized by radiologic investigations, Ultrasound and computed tomography (CT) are helpful to define the cystic mass . Magnetic Resonance Imaging (MRI) is the gold standard to characterize surrounding tissues and define origin and extent of the pelvic mass. These cysts have been observed in 1 to 2% of female pelvic MRI examinations .
In our case, we did contrast CT due to low cost keeping in mind the socio-economic condition of the patient. The radiologist described a globular cystic lesion prolapsing through the vulva stretching the cervix till above the introitus with no evidence of filling of the contrast in the delayed phase within the cystic lesion. Use of MRI might have allowed better characterization of the müllerian vaginal cyst as MRI affords excellent visualisation of the vagina and surrounding tissue, offering high-contrast resolution and multiplanar capabilities . Retrograde urography into the cystic lesion permits the investigation of the proximity of the urinary tract to the cyst.
Full surgical excision constitutes a good management option. As the margins of the cyst were well defined on vaginal examination, we took the vaginal route to excise the cyst which also facilitated the vaginal hysterectomy by creating space for manipulation of the uterus.
Vaginal cysts usually do not necessitate medical intervention as they may not cause symptoms. Salete et al had followed up 4 patients of age group (37-53 years) for 2 to 17 years.; no indication for operative management appeared during that time . The management of the symptomatic vaginal cysts is primarily surgical. . Many authors have proposed marsupialization of the cyst, and it seems that it is a safe, minimally invasive technique with satisfactory long-term results . The size of the cyst may cause difficulties during its excision, and a combined approach (abdominal-perineal or laparoscopic-perineal) may be adopted by the surgeons in order to secure its complete removal.
4. Conclusion
Cystic lesions of the vagina are a common occurrence in women in their third and fourth decades, and represent a spectrum of disease from embryological derivatives to preneoplastic lesions . Mainly these are small in size and asymptomatic. Large symptomatic vaginal cysts can present as genital prolapse and may be difficult to diagnose. When evaluating an anterior vaginal cyst, assessment of the lesion via history taking and pelvic examination is important to confirm lesion size and location. Imaging by ultrasound or MRI is essential for diagnosis. The surgical excision of symptomatic lesion is the preferred modality of treatment with a favorable outcome for the patients.
