Ovarian endometrioma: a report of a pediatric case diagnosed prior to menstruation. Surg Case Rep 2024; 10:152. [PMID: 38898208 PMCID: PMC11187045 DOI: 10.1186/s40792-024-01951-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2024] [Accepted: 06/12/2024] [Indexed: 06/21/2024] Open
Abstract
BACKGROUND Ovarian endometriomas (OEs) are rarely found in the pediatric population, especially before menstruation. We report a 6-year-old girl who was postoperatively diagnosed with OE before menstruation. CASE PRESENTATION A 6-year-old girl presented to a local pediatrician with abdominal pain and vomiting. Abdominal ultrasonography revealed a multilocular cystic lesion to the left of the bladder. Magnetic resonance imaging (MRI) revealed similar findings, with the contents of the cyst showing a low signal on T1-weighted imaging and a high signal on T2-weighted imaging. The patient was referred to our institution for further examination. Enhanced computed tomography (CT) showed a multilocular cystic lesion sized 56 × 44 × 30 mm with partial calcification. The left ovarian vein was dilated, suggesting the origin of the tumor to be the left ovary. Extirpation of the lesion was performed under laparoscopic assistance. Pathological findings indicated an ovarian endometrioma. To our knowledge, this is the youngest report of an OE diagnosed in a patient prior to menstruation. CONCLUSIONS OEs in children before menstruation are extremely rare; thus, the long-term prognosis is yet to be determined.

Abstract
BACKGROUND There has been considerable progress in our understanding of endometriosis, but its pathophysiology remains uncertain. Uncovering the underlying mechanism of the rare instances of endometriosis reported in early postmenarcheal years and in girls before menarche can have wide implications. METHODS We conducted a literature review of all relevant articles on Medline. RESULTS In the review, we explore the pathogenetic theories of premenarcheal endometriosis, the role of retrograde menstruation in the adult and its potential role in early-onset disease, as well as the factors that argue against the existence of a link between early-onset endometriosis (EOE) and neonatal uterine bleeding (NUB). CONCLUSIONS As with endometriosis in adult women, the pathogenesis of early-onset disease remains unclear. A link between NUB and EOE is plausible, but there are considerable challenges to collating supporting evidence. The state of our understanding of early uterine development and of the pathophysiology of NUB leaves many unknowns that need exploration. These include proof of the existence of viable endometrial cells or endometrial mesenchymal stem cells in NUB, their passage to the pelvic cavity, their possible response to steroids, and whether they can reside within the pelvic cavity and remain dormant till menarche.

Abstract
Purpose To analyze the characteristics of the ovarian endometrioma (OE) across the life span of a woman. In the past, the OE has traditionally been viewed as a single, monolithic disease. Today, there are emerging data indicating that OE phenotypes differ according to the age of the woman. Method A narrative review of original articles on OE indexed by PubMed. Results When appearing in infancy and early adolescence, OE may be the consequence of endometrial cells retrogradely shed with neonatal uterine bleeding. The post‐menarcheal variant, manifesting itself during full adolescence, is singularly frequent in the presence of vaginal or uterine outflow obstructive anomalies. The typical and most frequent adult phenotype is characterized by increasing fibrosis and a tendency to progress; its mere presence exerts a detrimental effect on the surrounding healthy ovarian tissue. In postmenopause, an old lesion may be reactivated in the presence of exogenous or endogenous estrogens, or even be produced ex novo; rarely, it can spread to a variety of organs and structures and even degenerate causing malignancies. Conclusions Given the existence of these variants, it is important to agree on management guidelines that take into consideration these different phenotypes. Traditionally, ovarian endometriomas are considered rightfully as one subtype of endometriosis that is different from other subtypes. Beyond that, it is considered as a monolithic disease entity. In this review, we synthesized published data and argue that this subtype actually has age‐dependent phenotypes, and as such, management should be ideally tailored to achieve the best results.

Abstract
Early diagnosis and long-term management of endometriosis is important in adolescent girls considering their potential for future pregnancy and need for preventing disease progression. However, symptoms and clinical findings of adolescent endometriosis may differ from those of typical adult endometriosis, making diagnosis difficult. In adolescents, menstrual pain may present as acyclic and unresponsive to commonly used medication. Typical imaging findings in adult endometriosis, such as ovarian endometriotic cysts and fibrotic scars, are less common in adolescents. Peritoneal lesions, characteristic of early-stage endometriosis, are commonly found in this age group. It should be noted that endometriosis may also be found in adolescents before menarche, because of premenarcheal endometriosis or congenital uterine anomaly and outflow obstruction; the latter requiring surgical correction. Although surgery is reported to be effective for pain, postsurgical recurrence rate is high, and the effect of hormonal treatment is controversial. The optimal timing for surgical intervention also remains to be determined. Here, we aim to identify the unique characteristics of endometriosis in adolescents to achieve early diagnosis and optimal management for this group of patients.

Abstract
Young girls before menarche or menstruating adolescent women may experience long-term drug-resistant chronic pelvic pain, as well as other symptoms associated with pelvic mass. In such cases, it is of great importance to consider ovarian endometrioma in the differential diagnosis. In general, endometrioma is recognized as an ovarian cyst. However, in most cases, the pathology represents pseudocyst with a partial or complete endometrial-like lining with extraovarian adhesions and endometriotic implants which are likely to occur at the sites of ovarian adhesions and at the ceiling of the ovarian fossa. Ovarian endometriomas occur in 17–44% patients with endometriosis and account for 35% of all benign ovarian cysts. The time span from the onset of menarche to the time of endometrioma formation, which requires surgical intervention, has been evaluated to be a minimum of 4 years. The pathogenesis of early-life endometrioma may be different from other types of endometriosis. Diagnosis is often delayed, especially in adolescents, who tend to wait too long before seeking professional help. The three specific aims of treatment in adolescents with endometriosis and endometriomas are control of symptoms, prevention of further progression of the disease as well as preservation of fertility. Increasing evidence demonstrates association between ovarian endometriosis and ovarian cancer. In the present mini-review, we draw the particular attention of clinicians to such a possibility, even if relatively infrequently reported.

Abstract
Increasing evidence indicates that early onset endometriosis (EOE), starting around menarche or early adolescence, may have an origin different from the adult variant, originating from neonatal uterine bleeding (NUB). This implies seeding of naïve endometrial progenitor cells into the pelvic cavity with NUB; these can then activate around thelarche. It has its own pathophysiology, symptomatology and risk factors, warranting critical management re-evaluation. It can also be progressive, endangering future reproductive capacity. This variant seems to be characterized by the presence of ovarian endometrioma. Today, the diagnosis of endometriosis in young patients is often delayed for years; if rapidly progressive, it can severely affect pelvic organs, even in the absence of serious symptoms. Given the predicament, great attention must be paid to symptomatology that is often non-specific, justifying a search for new, simple, non-invasive markers of increased risk. Better use of modern imaging techniques will aid considerably in screening for the presence of EOE. Traditional laparoscopy should be limited to cases in which imaging gives rise to suspicion of severity and a stepwise, minimally invasive approach should be used, followed by medical treatment to prevent recurrence. In conclusion, EOE represents a condition necessitating early diagnosis and stepwise management, including medical treatment.

Abstract
There continues to be debate over the nature and progression of ovarian endometriomas in adolescence due to the possibility that they may have a different origin and to the impossibility to be able to predict progress. The hypothesis of a different origin traces its roots in the phenomenon called “neonatal menstruation” (NUB), occurring in approximately 5% of newborn. The retrograde shedding of neonatal endometrium may contain progenitor cells and stroma that may lie dormant under the peritoneal surface until being activated when estrogens begin to rise. In teenagers, ovarian endometriomas are often preceded by highly angiogenic implants in the fossa ovarica, with adhesion formation resulting in the invagination of the ovarian cortex and the creation of a pseudocyst. Use of imaging techniques makes it possible to diagnose even small endometriomas. This is vital to their management, since there is evidence that the disease in an adolescent represents a severe condition, with tendency to progression. In addition, if intervention is decided, the first surgical procedure can determine the ultimate outcome of her reproductive life, because there is a significantly higher risk of inadvertently removing ovarian tissue in the presence of an endometrioma than of other ovarian pathologies. For this reason, techniques avoiding additional trauma to the ovary should be preferred and those who wish to become pregnant should attempt conception as soon as possible; if pregnancy is not sought, hormonal therapy is strongly advised. Finally, young age at diagnosis may constitute a pivotal factor in considering fertility preservation.

Abstract
Endometriosis is defined as the presence of endometrial glands and stroma outside the uterus. It affects 3 to 10 percent of women of reproductive age. Umbilical endometriosis is rare, with an estimated incidence of 0.5–1.0% among all cases of endometriosis, and is usually secondary to prior laparoscopic surgery involving the umbilicus. In this report, we described a case of umbilical endometriosis treated with surgical resection and highlight the great importance of medical history compared to complementary diagnostic tests that can be sometimes inconclusive.

Abstract
The incidence and severity of endometriosis in adolescent are comparable with the incidence in adult women. The mean delay between the onset of symptoms and the final diagnosis varies between 6.4 and 11.7 years. The longer the diagnosis is delayed, the more the endometriosis can progress to a more severe stage certainly in the group of patients with pelvic pain. The evolution of endometriosis and its progressivity are not predictable, and the severity of the disease is not directly related to the degree of pain. Endometriotic cysts have a detrimental effect on the ovarian reserve by the evolution in time and the surgical excision technique. Already, in small endometriotic cysts (<4 cm), loss of follicular reserve is present together with the formation of fibrosis in the cortex of the ovary. Early diagnosis of endometriosis in the adolescent deserves our full attention. Non-invasive imaging techniques like 2-D and 3-D ultrasound are helpful in the early diagnosis. Early ablative surgery is recommendable. Although laparoscopy is traditionally recommended, transvaginal laparoscopy has been shown to be most effective in ablating endometriomas with a maximum diameter of 3 cm. Early detection and intervention will contribute to a better quality of life in these adolescents and also to a lower damage of the ovarian tissue by a less invasive ablative surgery.

Abstract
To improve the still fragmented understanding of endometriosis, a life cycle approach was adopted that revealed unexpected aspects of the natural history of the disease throughout a woman's life. Three age-related stages of endometriosis are distinguished. In premenarcheal and adolescent endometriosis, 2 types can be distinguished: a classic form that can occur before menarche, and a congenital obstructive form that is caused by uterine anomaly and outflow obstruction. The lesions include superficial peritoneal implants, but adhesions and endometrioma can also occur. It is suggested that premenarcheal and possibly adolescent endometriosis develop by activation of resting stem cells shed at the time of neonatal retrograde uterine bleeding. In the adult, endometriosis can be related to uterine preconditioning by cyclic menstruations acting as a priming mechanism for deep placentation. In adult life, the typical lesions are peritoneal, ovarian, and deep or adenomyotic endometriosis. More recently, endometriosis has been associated with endometrial dysfunction and myometrial junctional zone hyperplasia. These uterine changes can be linked with some major obstetrical syndromes. In postmenopause, endometriosis can develop or be reactivated both in the presence or absence of exogenous estrogens and can spread to a variety of organs and structures causing constrictive lesions.
