Endometrial stromal sarcoma (ESS) is an extremely uncommon uterine malignancy, and commonly arises from preexisting endometriosis. On rare occasions, ESS arises from extrauterine tissues and is known as extra-uterine ESS. …
Ovarian endometriosis (OEM) is characterised by ectopic endometrial tissue growth within the ovary. In these ectopic lesions, the ectopic epithelium plays a crucial role in OEM progression and has been …
Primary peritoneal clear cell carcinoma (PPCCC) is an exceptionally rare malignancy that closely resembles gynecologic epithelial cancers clinically and histologically. Its pathogenesis is poorly understood, with possible origins from Müllerian …
Cystic adenomyoma is a rare focal cystic variant of adenomyosis, and giant lesions are particularly uncommon. Malignant transformation has been reported in endometriosis-related disease, but the molecular features of cystic …
Endometriosis is a benign, estrogen-dependent condition affecting 6%-10% of women of reproductive age, typically involving pelvic organs but occasionally presenting in extrapelvic locations such as the umbilicus. We report a …
A mural solid component (SC) within an endometrioma (ovarian endometriotic cyst), demonstrating internal vascularity or increased fluorodeoxyglucose (FDG) uptake on positron emission tomography (PET), is considered a characteristic finding suggestive …
Endometriosis-associated ovarian cancer (EAOC) is a distinct form of epithelial ovarian cancer that arises from the malignant transformation of benign endometriotic lesions. While epithelial-mesenchymal transition (EMT) is acknowledged as a …
Extrauterine adenosarcomas are rare gynecologic malignancies that can arise within foci of pelvic endometriosis. They are often hormone mediated and thus are challenging to treat during pregnancy.
