1 Corpus luteum cysts exhibit a convoluted lining with luteinized granulosa and theca cells.Corpus luteum of the ovary, medium power. The granulosa cells have undergone proliferation and alteration to lutein cells that produce progesterone. The lutein cells are large and polyhedral and the cytoplasm is foamy and eosinophilic.Knowledge Weavers Human Reproduction
2 Mucinous cystadenomaThese tumors comprise 20% of all neoplasms, and 50% of ovarian neoplasms found in women less than 20 years of age. They are frequently multiloculated. The favored hypothesis for their origin is metaplastic surface epithelium as they have a predominance of endocervical gland type epithelium.Knowledge Weavers Human Reproduction
3 Ovarian tumorA large vertical incision allows delivery and excision of an ovarian neoplasm. Pelvic washings for cytology and a frozen section rule out a malignancy. The cyst is excised carefully to avoid spilling contents into the abdomen.Knowledge Weavers Human Reproduction
4 Ultrasound of placental abruptionThe fetal body and bladder are labeled FB, and BL, respectively.Knowledge Weavers Human Reproduction
5 Uterine ruptureUterine ruptureKnowledge Weavers Human Reproduction
6 Brenner tumorSolid and partially cystic epithelial nests are surrounded by a stroma composed of bundles of tightly-packed spindle shaped cells. The epithelial cells are polygonal and of the squamoid type, with pale, eosinophilic cytoplasm and oval nuclei having distinct nuclei and longitudinal grooving, a coffee...Knowledge Weavers Human Reproduction

16 Mature cystic teratoma-torsed with adenexal structuresElements of all three germ layers are present: endoderm, mesoderm, and ectoderm. They are classified as germ cell tumors and are thought to arise through parthenogenesis. They are found in the path of migration of the germ cells from the yolk sac to the primitive gonad.PathogenesisKnowledge Weavers Human Reproduction
17 Total placenta previa: placenta accreta in uterine specimenPlacenta accreta or percreta may be associated with placenta previa especially if the patient has had a previous cesarean section.Knowledge Weavers Human Reproduction
