Mature cystic teratoma co-existing with a mucinous cystadenocarcinoma is an infrequently encountered entity with only a handful of cases reported till date. The possibilities in such a case are either a malignant transformation of a benign teratoma into adenocarcinoma or a collision tumor between a mature cystic teratoma and a mucinous tumour of either a primary ovarian surface epithelial-stromal origin or a secondary from a primary gastrointestinal tract tumour. The importance of distinguishing between the two entities has significant bearing on subsequent therapeutic management...

In fetal females, oogonia proliferate immediately after sex determination. The progress of mitosis in oogonia proceeds so rapidly that the incompletely divided cytoplasm of the sister cells forms cysts. The oogonia will then initiate meiosis and arrest at the diplotene stage of meiosis I, becoming oocytes. Within each germline cyst, oocytes with Balbiani bodies will survive after cyst breakdown (CBD). After CBD, each oocyte is enclosed by pre-granulosa cells to form a primordial follicle (PF). Notably, the PF pool formed perinatally will be the sole lifelong oocyte source of a female...

: Identifying the etiology of acute pelvic pain in girls is often clinically challenging. Particularly in young girls, it is often difficult to determine if acute pelvic symptoms are originating from a gynecologic source or from a genitourinary or gastrointestinal etiology based on the child's clinical examination alone. Therefore, imaging plays a key role in establishing a diagnosis and in directing medical and surgical treatment. Pediatric gynecologic conditions, which can present acutely with pain or mass or both include ovarian torsion, hematometrocolpos, pelvic inflammatory disease, inguinal hernias containing an ovary or the uterus or both, adnexal cysts, pregnancy, vaginal foreign bodies, and ovarian vein thrombosis...

The female reproductive lifespan is largely determined by the size of primordial follicle pool, which is established following germ cell cyst breakdown around birth. Almost two-third of oocytes are lost during germ cell cysts breakdown, following autophagic and apoptosis mechanisms. To investigate a possible relationship between germ cell cyst breakdown and nutrition supply, we established a starvation model in mouse pups at birth and evaluated the dynamics of cyst breakdown during nutrient deprivation. Our results showed that after 36 h of starvation between 1...

Mature ovarian cystic teratoma (also known as ovarian dermoid cyst) is a slow growing encapsulated tumor which contains well differentiated derivations of at least two out of three germ cell layers (i.e., ectoderm, mesoderm and endoderm). The lesion is lined by ectodermally derived squamous epithelium containing skin appendages. The cyst content commonly consists of keratin, sebaceous materials and fat. On CT images, the intracystic globules of sebum/fat could appear as multiple free floating rounde hypoattenuating nodules, giving the classical 'sack-of-marbles' appearance...

Factor V deficiency is a rare autosomal recessive coagulation disorder. We are reporting a case of a 13 year old girl with factor V deficiency presenting as life threatening haemoperitoneum, following bleeding from ruptured ovarian cyst. Prolonged Prothrombin Time, Activated Partial Thromboplastin Time and a normal platelet count pointed towards a disorder of coagulation. Mixing study with factor V deficient plasma and coagulation factor assay revealed markedly reduced plasma factor V clotting activity.

BACKGROUND: Ectopic pregnancies occur when the implantation of a fertilized ovum occurs outside the endometrial cavity. Such pregnancies occur in approximately 1.5% to 2.0% of all pregnancies and cause 6% of maternal deaths. OBJECTIVES: To evaluate osteopathic structural examination (OSE) findings in patients with ectopic pregnancies of uncommon locations and to establish the utility of these findings in the diagnosis of these ectopic pregnancies. METHODS: In this prospective case series, a focused OSE was performed on each patient with an ectopic pregnancy at her initial presentation after the patient history but before other diagnostic or laboratory tests were performed and surgical treatment was initiated...

A 50-year-old post-menopausal woman with sudden lower abdominal pain was transported to hospital by ambulance. Abdominal symptoms and computed tomography(CT)suggested a diagnosis of acute pan-peritonitis due to gastrointestinal perforation, and emergency surgery was performed. The intraoperative findings led to a diagnosis of a ruptured cyst in the left ovary, a portion of which was observed to be partially solid, and therefore, ovarian cancer was suspected. Accordingly, a unilateral(left)salpingo-oophorectomy and intraperitoneal drainage were performed with assistance from a gynecologist...

The patient was a 61-year-old man. Computed tomography(CT)in April 2007 revealed a pancreatic cyst in the tail of the pancreas. Rapid enlargement was noted in November 2007, and the patient was referred to the surgery department. CT showed a cystic lesion containing a nodular shadow in the pancreatic tail. Tumor marker measurements yielded normal carcinoembryonic antigen(CEA)and carbohydrate antigen 19-9(CA19-9)levels, but the duke pancreatic monoclonal antigen type 2(DUPAN-2)level was elevated. A diagnosis of mucinous cystic neoplasm(MCN)of the pancreas was made in December 2007, and distal pancreatectomy and partial colectomy were performed...

BACKGROUND: Management of solitary mucinous cystic lesions of the pancreas (MCLs) relies on correct differentiation between branch-duct intraductal papillary mucinous neoplasm(BD-IPMN) and mucinous cystic neoplasm(MCN). Current international consensus guidelines recommend resection for MCN, whereas unifocal BD-IPMN may be followed in the absence of worrisome features/high-risk stigmata. We hypothesized that preoperative differentiation of solitary MCLs is suboptimal, and that all solitary MCLs should be treated similarly...
