Juvenile cystic adenomyomas: acquired adenomyosis variant or congenital Müllerian defects?

Submucosal cystic adenomyosis: a report of five cases and review of the literature

AIM

To investigate the clinical characteristics, diagnosis, and clinical treatment of submucosal cystic adenomyosis.

METHODS

The clinical data of five cases of patients with submucosal cystic adenomyosis in our hospital from January 2020 to June 2023 were retrospectively analyzed.

RESULTS

The average age of the patients was 37.8 ± 4.5 years old, three of them experienced prolonged menstruation and heavy menstrual bleeding. All patients had a history of abnormal uterine bleeding and mild to moderate dysmenorrhea, with a VAS score of 2.8 ± 1.6. The average Carbohydrate antigen 125 (CA125) value was 29.9 ± 23.6U/ml. Two out of the five patients (40%) had CA125 values above the upper limit of normal. The nodules had a diameter of 3.2 ± 1.3 cm and a cavity size of 1.3 ± 0.7 cm. Color ultrasound revealed hypo or iso or anechoic echoic cysts, and blood flow signals were detected. The magnetic resonance imaging (MRI) findings varied among each patient. All the patients underwent hysteroscopy and resection of uterine cavity-occupying lesions, and no recurrence was observed.

CONCLUSIONS

The clinical features of submucosal cystic adenomyosis include abnormal uterine bleeding and menstrual changes, and the degree of dysmenorrhea is generally not severe. The diagnostic utility of CA125 in submucosal cystic adenomyosis may be limited. The three-dimensional ultrasound and MRI are valuable preoperative examination methods currently. Hysteroscopy can not only diagnose submucosal cystic adenomyosis, but also treat it, and preserve the fertility function of the patient.

Impact of an accessory cavitated uterine mass on fertility: case presentation and review of the literature

Objective

We report a case of an accessory cavitated uterine mass (ACUM) in a patient with infertility and chronic pelvic pain. In addition, we summarize the literature to better characterize ACUM diagnosis and management.

Design

A comprehensive literature search using the PubMed database was performed through April 2023. Historical ACUM diagnostic criteria were applied as inclusion criteria. Descriptive statistics and statistical evaluation were reported.

Results

A 31-year-old nulligravid woman presented with chronic pelvic pain, dysmenorrhea, primary infertility, and history of endometriosis. Three-dimensional ultrasonography identified an ACUM and laparoscopic excision provided complete resolution of symptoms. Subsequently, she conceived without assistance twice with uncomplicated vaginal deliveries. A total of 154 articles were identified, 34 papers met inclusion criteria and were individually reviewed, consisting of 70 reported cases. The most common presenting complaints were dysmenorrhea (81.4%), chronic pelvic/abdominal pain (54.1%), and refractory pain (34.3%). Diagnostic imaging included magnetic resonance imaging (62.9%) and transvaginal ultrasound (55.7%). Management included resection via laparoscopy (75.7%) or laparotomy (18.6%), or hysterectomy (5.7%). Of cases with reported outcomes, 90.7% had complete relief of symptoms after surgery.

Conclusion

ACUM often presents with dysmenorrhea, chronic pelvic pain, or abdominal pain and is identifiable on magnetic resonance imaging as a hyperenhancing mass. Three-dimensional transvaginal ultrasound can also accurately identify ACUM. A total of 90.7% of patients had complete relief of symptoms after intervention. It is important to identify ACUM early to relieve pain and reduce unnecessary interventions. Like our patient, other reports have demonstrated concomitant infertility and endometriosis. However, further investigation is needed to explore the association between infertility and ACUM.

Pathogenesis Based Diagnosis and Treatment of Endometriosis

Understanding the pathophysiology of endometriosis is changing our diagnosis and treatment. Endometriosis lesions are clones of specific cells, with variable characteristics as aromatase activity and progesterone resistance. Therefore the GE theory postulates GE incidents to start endometriosis, which thus is different from implanted endometrium. The subsequent growth in the specific environment of the peritoneal cavity is associated with angiogenesis, inflammation, immunologic changes and bleeding in the lesions causing fibrosis. Fibrosis will stop the growth and lesions look burnt out. The pain caused by endometriosis lesions is variable: some lesions are not painful while other lesions cause neuroinflammation at distance up to 28 mm. Diagnosis of endometriosis is made by laparoscopy, following an experience guided clinical decision, based on history, symptoms, clinical exam and imaging. Biochemical markers are not useful. For deep endometriosis, imaging is important before surgery, notwithstanding rather poor predictive values when confidence limits, the prevalence of the disease and the absence of stratification of lesions by size, localization and depth of infiltration, are considered. Surgery of endometriosis is based on recognition and excision. Since the surrounding fibrosis belongs to the body with limited infiltration by endometriosis, a rim of fibrosis can be left without safety margins. For deep endometriosis, this results in a conservative excision eventually with discoid excision or short bowel resections. For cystic ovarian endometriosis superficial destruction, if complete, should be sufficient. Understanding pathophysiology is important for the discussion of early intervention during adolescence. Considering neuroinflammation at distance, the indication to explore large somatic nerves should be reconsidered. Also, medical therapy of endometriosis has to be reconsidered since the variability of lesions results in a variable response, some lesions not requiring estrogens for growth and some being progesterone resistant. If the onset of endometriosis is driven by oxidative stress from retrograde menstruation and the peritoneal microbiome, medical therapy could prevent new lesions and becomes indicated after surgery.
