Introduction: Ectopic ovarian tissue is a rare gynecologic problem. The nomenclature and classification systems are unclear and still debated.
Case Report: Herein we provide a case report and review the literature to help clarify the classification system of ectopic ovarian tissue.

Heterotopic pregnancy is defined as the simultaneous presence of an intrauterine and an extrauterine pregnancy and is considered a rare condition. As a part of this entity, heterotopic triplet pregnancy, defined as the presence of three embryos, with at least one being ectopic, is exceedingly rare. In recent years, the broad use of assisted reproductive techniques to help infertile couples has contributed to the constant rise of non-spontaneous heterotopic triplets.

Endometrioma is a localized form of endometriosis, usually found within the ovaries bilaterally, containing degenerated blood products resulting from bleeding of ectopic endometriotic tissue at different ages. Rupture of the endometrioma is a rare complication that may result in hemoperitoneum and peritonitis and thus presents similarly to other more common abdominal emergencies, and the concomitant presence of a ruptured endometrioma and another abdominal emergency, although exceptional, remains possible. Ultrasonography and sectional imaging can be used to assess a diagnosis that is often confirmed postoperatively.

Currently, hormonal therapy for endometriosis faces challenges in achieving a balance between treatment and preserving the chance of pregnancy. Therefore, the development of non-hormonal therapy holds significant clinical importance. Angiogenesis is a hallmark of endometriosis, and anti-angiogenic therapies targeting the hypoxia-inducible factor-1α (HIF-1α) pathway are considered potential approaches for endometriosis.

The gene-regulatory mechanisms controlling the expression of the germline PIWI-interacting RNA (piRNA) pathway components within the gonads of metazoan species remain largely unexplored. In contrast to the male germline piRNA pathway, which in mice is known to be activated by the testis-specific transcription factor A-MYB, the nature of the ovary-specific gene-regulatory network driving the female germline piRNA pathway remains a mystery. Here, using as a model, we combined multiple genomics approaches to reveal the transcription factor Ovo as regulator of the germline piRNA pathway in ovarian germ cells.

Endometriosis is a chronic condition with limited therapeutic options. The molecular aberrations promoting ectopic attachment and interactions with the local microenvironment sustaining lesion growth have been unclear, prohibiting development of targeted therapies. Here, we performed single-cell and spatial transcriptomic profiling of ectopic lesions and eutopic endometrium in endometriosis.
