Benign Biphasic Tumors of the Mullerian Tract - a Mimic of Phyllodes Tumor. A Clinical-Pathologic Description of 21 Cases

OBJECTIVE

A review of the clinical-pathologic characteristics and outcomes of biphasic polyps occurring in the female genital tract, not meeting the diagnostic criteria of Mullerian Adenosarcoma (MA).

METHODS

An archival database search was run, after IRB approval, between 2001 and 2019, using terminology such as "Mullerian adenofibroma," "atypical Mullerian adenofibroma," "polypoid adenofibroma," and "atypical polyp with increased stromal cellularity." Two pathologists (JW and MRQ) reviewed all the retrieved cases and documented the morphologic features with particular emphasis on the presence of any features of Mullerian adenosarcoma. Follow-up data were also abstracted.

RESULTS

Twenty-one cases, 12 cervical and 9 endometrial lesions, constituted the study cohort. Patients ranged from 26 to 64 years (median 49 years). On review, 20 of 21 of those cases showed Phyllodes-like architectural patterns. However, only one case showed all four features of MA, all of which were focal and inconspicuous. Follow-up (median duration of 5 years) did not document any recurrences in any of the 21 cases after excision.

CONCLUSION

This series adds to the growing body of literature affirming the existence of benign biphasic Mullerian polyps encountered in the endometrium and cervix that fall short of the Mullerian adenosarcoma diagnosis.

Cervical rhabdomyoma a rare entity: Case report with review of literature

Genital rhabdomyomas are extremely rare benign tumors of skeletal muscle origin, majority of them being reported in vaginal location. Extensive literature search revealed only three such cases reported in cervix. We hereby report fourth such case of cervical rhabdomyoma in a 35-years-old female patient. The diagnosis was confirmed by histomorphology with desmin and myoD1 positivity on immunohistochemistry. Due to paucity of cases no definite treatment guidelines are available. Differentiation from identical and more common malignant counterpart which is rhabdomyosarcoma is essential to avoid unnecessary aggressive therapy.

Cervical polyp: evaluating the need of routine surgical intervention and its correlation with cervical smear cytology and endometrial pathology: a retrospective study

Objective

To determine the frequency of premalignant and malignant lesions in cervical polyps in order to examine whether cervical polyps need to be removed routinely and also to appraise its association with cervical smear cytology and endometrial pathologies.

Methods

We retrospectively re-examined the hospital records of 299 cases over a period of 5 years. All patients were segregated into perimenopausal and postmenopausal groups according to their menopausal status. The groups were compared in terms of histological results of cervical polyp biopsy, endometrial pathologies, and cervical smear cytology. Pearson’s χ² test and Fisher’s exact test were used for statistical analysis, and a P-value of <0.05 was accepted as statistically significant.

Results

In the histopathological reports of cervical polyps, premalignant lesions were found in 2% of cases, and only 0.3% of malignant lesion was observed in menopausal women. Subsequently, no malignancy was noted in cervical smear cytology for both groups. Premalignant and malignant lesions in endometrial histopathology findings were 1.33% and 0.66%, respectively. There was a statistically significant association between the menopausal status of the patient and cervical smear cytology and endometrial pathology, but the histological findings were not statistically significant in relation to the symptomatic status of the patients.

Conclusion

As per the results, we strongly suggest the removal of all cervical polyps with subsequent histological review. The evaluation of cervical smear cytology prior to polypectomy can provide information about its malignancy potential. We believe that along with cervical polypectomy, endometrial sampling should be recommended, especially for postmenopausal women.

Risk factors for spontaneous miscarriage above 12 weeks or premature delivery in patients undergoing cervical polypectomy during pregnancy

Background

It currently remains unknown whether the resection of cervical polyps during pregnancy leads to miscarriage and/or preterm birth. This study evaluated the risk of spontaneous PTB below 34 or 37 weeks and miscarriage above 12 weeks in patients undergoing cervical polypectomy during pregnancy.

Methods

This was a retrospective monocentric cohort study of patients undergoing cervical polypectomy for clinical indication. Seventy-three pregnant women who underwent polypectomy were selected, and risk factors associated with miscarriage above 12 weeks or premature delivery below 34 or 37 weeks were investigated. A multivariable regression looking for predictors of spontaneous miscarriage > 12 weeks and PTB < 34 or 37 weeks were performed.

Results

Sixteen patients (21.9%, 16/73) had spontaneous delivery at < 34 weeks or miscarriage above 12 weeks. A univariate analysis showed that bleeding before polypectomy [odds ratio (OR) 7.7, 95% confidence interval (CI) 1.6–37.3, p = 0.004], polyp width ≥ 12 mm (OR 4.0, 95% CI 1.2–13.1, p = 0.005), the proportion of decidual polyps (OR 8.1, 95% CI 1.00–65.9, p = 0.024), and polypectomy at ≤10 weeks (OR 5.2, 95% CI 1.3–20.3, p = 0.01) were significantly higher in delivery at < 34 weeks than at ≥34 weeks. A logistic regression analysis identified polyp width ≥ 12 mm (OR 11.8, 95% CI 2.8–77.5, p = 0.001), genital bleeding before polypectomy (OR 6.5, 95% CI 1.2–55.7, p = 0.025), and polypectomy at ≤10 weeks (OR 5.9, 95% CI 1.2–45.0, p = 0.028) as independent risk factors for predicting delivery at < 34 weeks. Polyp width ≥ 12 mm and bleeding before polypectomy are risk factors for PTB < 37 wks.

Conclusions

Our cohort of patients undergoing polypectomy in pregnancy have high risks of miscarriage or spontaneous premature delivery. It is unclear whether these risks are given by the underlying disease, by surgical treatment or both. This study establishes clinically relevant predictors of PTB are polyp size> 12 mm, bleeding and first trimester polypectomy. PTB risks should be exposed to patients and extensively discussed with balancing against the benefits of intervention in pregnancy.

Giant Cervical Angiomyomatous Polyp Masquerading Third-Degree Uterine Prolapse: A Rare Case with Review of Literature

Giant cervical polyps are rarely seen nowadays in routine day-to-day practice and are defined as a polyp with a size >4 cm. Giant cervical polyps protruding outside the vaginal canal causing diagnostic dilemma are rarely encountered in gynecologic practice. They masquerade as uterine inversion, prolapse, or cervical malignancy. Only a few cases have been reported in the literature. We hereby report a case of giant polyp of anterior lip of the cervix occurring in a multiparous woman and presented with something coming out per vagina. Histopathology of it came out to be angiomyomatous polyp (vascular leiomyoma) of the cervix that itself is a rare entity.

An Unusually Large Fibroepithelial Polyp of Uterine Cervix: Case Report and Review of Literature

BACKGROUND:

Fibroepithelial cervical polyps (FEPs) are benign growths protruding from the inner surface of the cervix. They are typically asymptomatic, but a very small minority can undergo malignant change. Giant cervical polyps with a size greater than 4 cm are rare entities with only 23 reported cases in the literature. Cervical polyps develop as a result of focal hyperplasia of the columnar epithelium of the endocervix.

CASE PRESENTATION:

We present the case of a giant fibroepithelial polyp measuring approximately 11 x 6 x 4 cm which was protruding from the anterior lip of the uterine cervix in a 51-year-old woman who clinically presented vaginal bleeding. She was nulligravida and doesn’t have a child. The speculum examination revealed a soft, mobile, painless irregular cerebriform mass on the cervix, protruding through the vagina. The polyp was excised using a scalpel, and the pedicle was sutured using the Vicryl 1-0 under short-term intravenous anaesthesia. Histopathological examination revealed a polypoidal tumour mass composed of cellular fibrovascular stroma covered with stratified squamous epithelium. Three months after the initial surgery, there was no recurrence seen.

CONCLUSION:

Cervical giant polyps are rare entities and occur mostly in perimenopausal women. Transvaginal polypectomy, as performed for this patient followed by histopathological examination is an adequate procedure for these lesions.

Preterm premature rupture of membrane after polypectomy using an Endoloop polydioxanone suture II(™)

Polypectomy using an Endoloop PDS II^™ during pregnancy can be responsible for miscarriage and preterm delivery. Cervical polyps should not be removed in pregnant women except in cases where a malignancy is suspected.

The diagnosis of uterine cervical polyps in a low resource setting: the positive predictive value of clinical judgment--a series of 192 cases at the Yaounde Gynaeco-Obstetric and Paediatric Hospital, Cameroon

As far as we know, the accuracy of clinical judgment in diagnosing uterine cervical polyps has not been assessed in sub-Saharan Africa. Our objective was to discover the positive predictive value (PPV) of clinical judgment in the diagnosis of cervical polyps. This is a retrospective descriptive study of 192 patients, carried out by the Departments of Pathology and Gynaecology of the Yaoundé Gynaeco-Obstetric and Paediatric Hospital, Cameroon. The diagnosis of cervical polyp was confirmed by histopathology examination in 169 patients, giving a PPV rate of 88.0%. The PPV of clinical judgment in the diagnosis of cervical polyps is acceptable in our setting but the frequency of premalignant and malignant lesions encountered is too high (10.4%), even in the presence of a confirmed cervical polyp (8.9%). Even in areas where there are limited resources, we recommend a systematic histopathology examination of any clinically suspected cervical polyp.
