Bioengineering is applied in different areas, including women's infertility management. Among other approaches, decellularized tissues are being used to treat uterine disorders causing infertility. Biomaterials made from decellularized tissue consist of tissue-specific extracellular matrix and, as acellular scaffolds, are thought to be immune inert.

Uterine transplantation along with assisted reproductive techniques can provide this option for women without a uterus. In the early research period, to minimize the risk of preterm birth and other pregnancy-related complications, the uterus of a donor with a history of one to three successfully completed pregnancies was recommended for transplantation.

Objective: To describe a rare case of a retroperitoneal Müllerian cyst in a teenage girl with a protruding uterus and associated urogenital anomalies, and to discuss the challenges faced in differential diagnosis and management of such cases.
Case Report: We present the case of a 14-year-old girl presented with a protruding uterus for several weeks, with a history of twin-twin transfusion syndrome at birth. Initial ultrasonography identified a large pelvic cystic tumor.

Introduction: Uterine transplantation is currently intended for women with absolute uterine infertility. Since proof of the concept in 2014, many countries have started research programs and clinical activities. However, access to uterine transplantation remains limited given that only a few hundred transplants have been described worldwide compared with the 1.

Transplantation of decellularized uterus tissue showed promise in supporting regeneration following uterine injury in animal models, suggesting an alternative to complete uterus transplantation for uterine factor infertility treatment. However, most animal studies utilized small grafts, limiting their clinical relevance. Hence, we used larger grafts (20 × 10 mm), equivalent to nearly one uterine horn in rats, to better evaluate the bioengineering challenges associated with structural support, revascularization, and tissue regeneration.
