Atypical polypoid adenomyoma and hysteroscopic endometrial ablation

A Clinicopathological Review of 203 Cases of Atypical Polypoid Adenomyoma of the Uterus

OBJECTIVE

To provide a reference for the diagnosis and treatment of atypical polypoid adenomyoma (APA).

METHODS

This was a retrospective study of 203 APA patients from 2011 to 2021. The clinicopathological characteristics, treatments, and prognosis were analyzed.

RESULTS

The average age at diagnosis of APA patients was 39.30 ± 11.01 years, and premenopausal women accounted for 81.3%. Abnormal uterine bleeding or menorrhagia were the most common clinical manifestations of APA. The uterine fundus (78.3%), followed by the lower segment of the uterus (11.8%), was the most common location of the APA lesions. Abnormal blood vessels were seen on the surface of 28 APA tumors. APA can coexist with atypical endometrial hyperplasia (18.2%) and endometrial cancer (10.8%). Immunohistochemical analysis was performed on 99 samples. In the glandular component, ER (94.8%), PR (94.8%), Ki-67 (51.5%), p53 (45.6%), PTEN (18.8%), and mismatch repair proteins (96.4%) were positively expressed. Stromal immunophenotype expression was exhibited as follows: CD10-(89.5%), p16+(86.9%), h-caldesmon-(66.7%), Desmin+(75%), and Vimentin+(88.9%). Fifty-five APA patients received TCR, and 33 of them received adjuvant therapy after the operation. The postoperative recurrence rate (9.1% vs. 36.4%, p < 0.05) and malignant transformation rate (3.0% vs. 18.2%, p < 0.05) of the treated group were significantly lower than the untreated group.

CONCLUSIONS

APA usually occurs in women of childbearing age, and the diagnosis is based on pathological morphology. APA has a low malignant potential, and those who have fertility requirements can undergo conservative TCR treatment, supplemented by progesterone treatment after surgery and close follow-up. Total hysterectomy is the treatment of choice for APA patients with atypical endometrial hyperplasia around the lesion.

Immunohistochemical results and case report of an incidental finding of uterine polypoid adenomyoma after long-time therapy for metrorrhagia

We present a 25-year-old female woman with a 9-year history of metrorrhagia, in whom a uterine polypoid adenomyoma (UPA) was incidentally detected. Intense nuclear staining in the uterine adenomyoma tissue showed an immunoreaction with BAF250a/ARID1A, Arginase-2 as well as 1LRH-2E1/NR5A2, suggesting a role of these proteins and transcriptional activity of their genes in uterine polypoid adenomyoma development. Neither Nidogen-2 nor SF-1/NR5A1 were expressed in UPA.

A multiple perspectives on atypical polypoid adenomyoma of uterus

Atypical polypoid adenomyoma (APA) is a rare benign uterine tumor, with less than 200 cases have been reported in English literature. Although, it is considered as a benign lesion and treated conservatively previously, more and more cases show that APA has a high rate of recurrence or residual, and is found to precede the development of carcinoma. Given the data from present research on APA, the therapy of APA becomes more complex and must be cautious, especially for the nulliparous and premenopausal patients. In addition, because of the low incidence, studies on this disease are less, and the etiology and pathogenesis of APA is still unclear. In this review, we aim to summarize recent researches concerning APA from multiple perspectives, including clinical presentation, histogenesis, immunohistochemistry and molecular features, diagnosis and differential diagnosis, treatment opinion and prognosis, which may provide theory and clinical basis for the future clinical treatment and research of this rare disease.

[Atypical polypoid adenomyoma: retrospective study about 8 cases from Jeanne-de-Flandre Hospital between 1996 and 2008]

OBJECTIVES

To propose a therapeutic approach and follow-up of patients with atypical polypoid adenomyoma (APA) wishing to remain fertile.

PATIENTS AND METHOD

We are presenting a retrospective study of eight APA cases.

RESULTS

Two patients immediately received radical treatment, and one patient had an endometrial thermocoagulation. The remaining five patients received a conservative treatment with ultrasound and hysteroscopic monitoring. Among them, two had full-term pregnancies, one is being treated for infertility, in one case, the APA disappeared after three hysteroscopy-curettages and macroprogestative treatment. Lastly, one of our patients died from an aggressive endometrioid ovarian bilateral tumour associated with an endometrial adenocarcinoma.

DISCUSSION AND CONCLUSION

Radical treatment is necessary for cases of APA in women no longer wishing to remain fertile. For those wishing to remain fertile, we can offer a conservative treatment once they have been informed regarding the associated risk of relapse, degeneration, and ovarian lesions which necessitate stricter follow-up.

Laparoscopic excision of uterine adenomyomas

OBJECTIVE

To present a series of six consecutive women with adenomyomas who were successfully managed with a standard treatment strategy to elucidate the feasibility and the effectiveness of laparoscopic treatment of adenomyomas.

DESIGN

Cross-sectional case series.

SETTING(S)

Obstetrics and gynecology department of a tertiary academic hospital and endoscopic unit of a private hospital.

PATIENT(S)

The six cases described in this report were nonpregnant women of reproductive age (mean age, 34.8 years old; range, 29-38 years) who presented in the outpatient gynecological clinic for yearly routine visit (one patient), dysmenorrhea and menorrhagia (three patients), and history of pregnancy loss (two patients).

INTERVENTION(S)

Laparoscopic excision of uterine adenomyomas.

MAIN OUTCOME MEASURE(S)

Feasibility and effectiveness of laparoscopic management of adenomyomas.

RESULT(S)

The average operating time was 100.5 minutes, and the average estimated blood loss was 163 mL. No event complicated the intraoperative and the postoperative course of these cases, and no case was converted to laparotomy. The mean follow-up was 13.7 months, with complete regression of the symptoms.

CONCLUSION(S)

Excision of adenomyomas presents intraoperative peculiarities involving difficulties in their dissection and manipulation. Laparoscopic management of these lesions appears to be safe and feasible with good follow-up results and limited recurrence rates.

Hysteroscopic treatment of atypical polypoid adenomyoma diagnosed incidentally in a young infertile woman

OBJECTIVE

To describe the conservative treatment of an atypical polypoid adenomyoma (APA) in a young infertile patient using a modification of the technique previously reported for the conservative treatment of stage IA endometrial cancer.

DESIGN

Case report.

SETTING

Department of Gynaecology and Obstetrics and Pathophysiology of Human Reproduction of the University of Naples "Federico II."

PATIENT(S)

A 35-year-old woman diagnosed incidentally with an APA during routine investigation for primary infertility.

INTERVENTION(S)

Conservative resectoscopic treatment using a four-step technique in which each step is characterized by a pathological analysis: the removal of the APA (step 1), the removal of endometrium adjacent to the APA (step 2), the removal of the myometrium underlying the APA (step 3), and multiple random endometrial biopsies (step 4).

MAIN OUTCOME MEASURE(S)

Complete resection of the APA and ruling out of any malignancy.

RESULT(S)

The conservative surgery was effective as histological examination of all specimens confirmed an APA confined to the endometrium without any other premalignant or malignant lesion. Transvaginal ultrasound and office hysteroscopy with target biopsies at 1 and 6 months after surgery were negative for atypia and malignancy.

CONCLUSION(S)

Our technique under a close, intermittent postoperative surveillance might represent a good therapeutic option for those women with APA who wish to preserve their fertility as well as for those at high medical risk for hysterectomy.
