Background: A chorangioma, a nontrophoblastic tumor, is a primary benign neoplasm of the placenta. It is found on the fetal surface of the placenta or in the placental parenchyma. Chorangiomas can have various histopathologic presentations, ranging from vascular to cellular, and can undergo degenerative changes. They can be diagnosed prenatally with ultrasound, color Doppler imaging, and magnetic resonance imaging. Case: A large placental chorangioma with secondary changes was found in a 32-year-old primigravida female who was referred to the Postgraduate Institute of Medical Sciences, in Rohtak, Haryana, India, at 36 weeks of gestation, with polyhydramnios and intrauterine growth restriction. Results: The patient herself delivered a placenta and deceased fetus without surgical intervention. The patient responded well after treatment. Conclusions: Chorangioma must be differentiated from other villous capillary lesions, namely, chorangiomatosis and chorangiosis. Most chorangiomas are small and possess no clinical significance. On the contrary, clinically significant chorangiomas, greater than 5 cm or multiple, may be associated with pregnancy complications. ( J GYNECOL SURG 31:26)
Background: Leiomyosarcomas are extremely rare primary ovarian smooth muscle tumors accounting for < 1% of ovarian malignancies. Case: A 30-year-old woman presented with complaints of pain and heaviness in the right iliac region. Abdominal examination revealed a pelvic mass, 18 weeks of gestation in size, with restricted mobility, palpable in the right iliac region. Ultrasonography (USG) revealed a large mass of 14.3 · 13.2 · 12.5 cm, occupying the whole of the pelvis just superficial to fundus, but not arising from the uterus. Magnetic resonance imaging (MRI) revealed a large oval well-defined mass in the right lower abdomen and pelvis. An excised right ovarian mass measuring 15 · 12 · 11 cm was sent for histopathologic examination. The cut surface of the mass was variegated, with areas of hemorrhage and necrosis. Results: On histopathologic examination, a diagnosis of leiomyosarcoma was made on morphologic and immunohistochemical grounds. Based on the diagnosis, the patient was given chemotherapy and has been followed-up since then. As of this writing, she is doing well. Conclusions: This case of ovarian leiomyosarcoma in a 30-year-old woman is extremely rare. In such cases, postoperative radiotherapy and chemotherapy for large tumor volumes may help control local disease and avoid metastatic recurrences. ( J GYNECOL SURG 30:297)
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
