1/39. The outcome after perinatal management of infants with potential airway obstruction.Masses in the head and neck are being detected prenatally with increasing frequency, necessitating the need for management of potential upper airway obstruction at delivery. Establishment of the airway at delivery and its maintenance thereafter are critical. This should optimally be performed with the baby still attached to the placental circulation. The importance of multidisciplinary team management, including a high risk obstetrician, neonatologist, pediatric otolaryngologist, pediatric thoracic surgeon, and an anesthetist, cannot be overemphasized. Endotracheal intubation is attempted first, if unsuccessful then is followed by insertion of a rigid bronchoscope. tracheotomy should be reserved for airway obstructions, which are not amenable to endotracheal intubation or in babies in whom exchange from a bronchoscope to endotracheal tube cannot be safely performed. The management of six infants with prenatally diagnosed potential airway obstruction is presented. morbidity and mortality still ultimately depend on the severity of the existent anomalies.- - - - - - - - - - ranking = 1keywords = tube (Clic here for more details about this article) |
2/39. Mixed malignant germ cell tumor of the fallopian tube.Immature teratomas of the fallopian tube are exceedingly rare with only three reported cases in the English literature. Reported here is a case of primary mixed malignant germ cell tumor of the fallopian tube composed of immature teratoma and yolk sac tumor.- - - - - - - - - - ranking = 1003.2467894781keywords = fallopian tube, tube (Clic here for more details about this article) |
3/39. eustachian tube teratoma and its terminological correctness.Teratomas are germ cell tumours usually found in the young and are characteristically composed of tissue foreign to the place where they arise. Two teratomas of the middle ear were first described in 1866 and since then, and to the best of our knowledge, 19 additional cases have been reported in the literature under different terms such as hairy congenital polyps, epidermoid cysts, dermoid cysts, hamartoma, cutaneous teratoma and teratomas. The difficulty in classifying germ cell tumours may explain the different terminologies encountered in the literature. The authors describe a case of teratoma of the eustachian tube presenting as a mass in the middle and external ear of a 10-week-old girl. Using this case, a review of the literature is performed in light of the new classification of germ cell tumours proposed by the world health organization (WHO). It is of note that most of the teratomas that present in the middle ear arise from, or involve, the eustachian tube.- - - - - - - - - - ranking = 6keywords = tube (Clic here for more details about this article) |
4/39. Dysembryoplastic neuroepithelial tumor (DNT): an ultrastructural study of six cases.We report six cases od DNT with a detailed ultrastructural characteristics. The patient age ranged from 7 to 16 years (mean 12), the location was temporal in three cases and frontal, temporooccipital and parietooccipital in each of one remaining cases. The predominant clinical feature in each case was history of episodes of intractable seizures. Histopathologically, the neoplasms were multinodular, each nodule was well-circumscribed and was composed of glioneuronal elements embedded in the variable amount of myxoid matrix. The oligodendroglial-like cells (OLC) predominated in the nodules with some accompanying mature neurons. The nodules were frequently surrounded by small calcifications which could be found also within the tumors. OLCs were immunoreactive for S-100 protein and neurons had the expression of synaptophysin and neurofilament proteins. Ultrastructurally, each tumor consisted of three major elements: neoplastic cells (OLC), elongated processes forming neuropil-like structure and expanded "mucoid" extracellular space: the latter gave an impression of cellular elements floating within it. Neoplastic cells had round, oval or elongated nuclei, no discernible nucleoli and a relatively narrow rim of the cytoplasm. Some nuclei were irregular and invaginated and pseudoinclusions were observed; a part of cytoplasm sequestered within pseudoinclusions often appeared degenerated with large blabs and electron-lucent vesicles, some of these contained in turn semicircular profiles of unknown significance. The second element consisted of innumerable cellular processes. Some of these were elongated and formed stacks connected by symmetrical symmetric or asymmetric adhesive plaque junctions. The others had shorter "neck" containing microtubules, these extended into bullous extensions. Dense-cored vesicles were occasionally observed, in both cytoplasm of neoplastic cells and within processes. In one cell, cross-sectioned annulate lamellae were found. In cytoplasm of a few cells, unusual inclusions reminiscent ribosome-lamellae complexes were observed. These were cylindrical resembling "laboratory tubes" with a cone-like endings. At higher power, walls of the "tubes" resolved into layered structures composed of several laminae; between laminae, ribosome-like structures were visible.- - - - - - - - - - ranking = 2keywords = tube (Clic here for more details about this article) |
5/39. Mature solid teratoma of the fallopian tube: case report.We report a mature solid teratoma arising in the fallopian tube. The mass was noted on CT scan prior to surgery for a mature cystic teratoma of the contra-lateral ovary. neoplasms of the fallopian tube are very uncommon. Moreover, the incidence of a mature solid teratoma of the fallopian tube is extremely low.- - - - - - - - - - ranking = 1170.4545877245keywords = fallopian tube, tube (Clic here for more details about this article) |
6/39. Primary carcinoma of the fallopian tube coexisting with benign cystic teratoma of the ovary.Primary carcinoma of the fallopian tube is a rare malignancy of the female genital tract and infrequently diagnosed before an operation. The majority of patients have extensive disease at the time of diagnosis. We have experienced incidentally a case of a carcinoma of the fallopian tube coexisting with a benign cystic teratoma of the ovary in a 25-year-old woman. We report this case with a brief review of literatures.- - - - - - - - - - ranking = 1003.2467894781keywords = fallopian tube, tube (Clic here for more details about this article) |
7/39. Laparoscopic cystectomy of a twisted, benign, ovarian teratoma in the first trimester of pregnancy.Adnexal torsion is an unusual, but serious complication in pregnancy. The treatment is surgical, but this may increase the risk of pregnancy loss in the first trimester. The use of laparoscopic surgery, which is less invasive than traditional laparotomy, has been limited by diagnostic and technical difficulties including determination of ovarian tumor nature and spillage of cyst contents intraoperatively. A 25-year-old woman in her 11th week of pregnancy had acute severe left lower-abdominal pain, which was diagnosed as left ovarian teratoma with torsion. She underwent emergency laparoscopic surgery with unwinding of the twisted fallopian tube and ovary and cystectomy of the teratoma. The patient subsequently delivered a full-term baby, without complications. Accurate ultrasound and cytologic diagnoses along with copious intraoperative warm, normal saline irrigation were likely contributing factors to the successful outcome of this case.- - - - - - - - - - ranking = 167.20779824635keywords = fallopian tube, tube (Clic here for more details about this article) |
8/39. Persistent mullerian duct syndrome with teratoma in an ectopic testis: imaging features.The persistent mullerian duct syndrome represents a rare form of male pseudohermaphroditism, secondary to mullerian inhibiting factor (MIF) deficiency. We describe imaging findings in a 30-year-old male (46 XY karyotype) with bilateral cryptorchidism and mullerian duct anomalies (presence of uterus and fallopian tubes). Grade-III teratoma with yolk sac tumour was detected in one of the undescended testis, lying in the pelvic cavity. The other testis was in the inguinal canal. The rest of the wolffian duct structures (e.g. prostate, seminal vesicles) were nearly normal. Very few reports of imaging findings of this entity have been published thus far, probably because of the rarity of entity, incidental detection of most of the cases at surgery and relatively asymptomatic clinical presentation.- - - - - - - - - - ranking = 167.20779824635keywords = fallopian tube, tube (Clic here for more details about this article) |
9/39. Intrapericardial teratoma masquerading as pyopericardium.A 10-year-old boy was admitted with cardiac tamponade. Initial pericardiocentasis yielded pus. A subxiphoid tube-pericardiostomy was done and thick, purulent material was drained out. Subsequently, pericardiectomy was undertaken as features of pericardial constriction persisted. At surgery, however, an intrapericardial mass was discovered. Successful excision was performed and the patient made an uneventful recovery. Histopathology of the mass revealed features of an intrapericardial teratoma. Rarity of the lesion, and a hitherto unreported mode of presentation make this case worthy of documentation.- - - - - - - - - - ranking = 1keywords = tube (Clic here for more details about this article) |
10/39. Juvenile fulminant adnexal tuberculosis caused by gastrointestinal tuberculosis immediately after ovarian cystectomy.Genital fulminant tuberculosis is rarely a primary site of infection. We report a case of juvenile adnexal tuberculosis possibly related to tuberculosis immediately after cystectomy in the ileocecal region in a virginal girl. A 13-year-old virginal girl visited our clinic because of a huge ovarian tumor, which was resected by cystectomy. On postoperative day 39, fever episodes were noted, and she received antibiotics, which were not effective. An abscess developed in the region of the cecum and the right adnexa. laparotomy revealed chronic abscess formation, especially in the right adnexa. Resection of the abscess was done. The pathological diagnosis was tuberculosis with caseation, although bacterial culture and molecular biological diagnosis for mycobacterium tuberculosis were negative in sputum, vaginal discharge, urine, and stool of the patient and her family. She was placed on anti-tuberculosis drugs, including isoniazid, rifampicin, and ethambutol, and this regimen was effective. This patient represents a rare case of fulminant adnexal tuberculosis without pulmonary disease.- - - - - - - - - - ranking = 15keywords = tube (Clic here for more details about this article) |
