Azumagawa K - - 1993
A 4-month-old male infant was seen because of an asymptomatic undescended left testis and a right sided abdominal mass. CT revealed a calcified retroperitoneal tumour. Histological examination of surgical specimens showed a mature primary teratoma of the contralateral undescended testis. While this is very rare, infants with undescended testis should ...

Gastric teratoma is a very rare, usually benign, tumour of childhood. In industrialized countries, the diagnosis is facilitated by advanced technology when the infant is still in utero or soon after birth, and surgery is performed quite early in life, long before symptoms appear. This tumour was seen in our ...

Teratomas of the testis in infants are rare tumors which often display immature elements, disturbing in their histologic appearance. Although the presence of similar histologic features worsens prognosis in testicular teratomas in adults and in teratomas of infants and children presenting at other anatomic sites, the presence of immature elements ...
Itoh M - - 1992
We report a 2-month-old female infant with a false aneurysm of the brachial artery and an 8-month-old male infant with a true aneurysm of a common digital artery. These traumatic aneurysms in the upper extremity are extremely rare in infants. In the former infant, reanastomosis of the brachial artery was ...
Brouwer M H - - 1992
Surgical treatment of a hypoplastic aortic arch associated with an aortic coarctation is controversial. The controversy concerns the claimed need to surgically enlarge the diameter of the hypoplastic arch, in addition to resection and end-to-end anastomosis. The purpose of this prospective study is to determine the fate of the hypoplastic ...

Proliferations of mature adipose tissue, while common in retroperitoneal and subcutaneous sites, rarely occur in the orbit. We describe the clinical, radiographic, and histopathologic findings of a nonencapsulated lipomatous tissue overgrowth of the right orbit in a 35-year-old man. The mass had caused proptosis since childhood and was apparently present ...
Dumbell H R HR Department of Paediatrics, University of Natal, - - 1990
A case of mediastinal teratoma, diagnosed in utero by realtime ultrasonography during a late 3rd trimester evaluation of polyhydramnios, is described. Prompt respiratory assistance to the infant at birth and early surgical intervention led to a successful outcome.
Sauter E R - - 1990
Oropharyngeal teratomas are rare congenital neoplasms that distort orofacial anatomy and often cause respiratory embarrassment at birth. Immediate management of such lesions should include establishment of a secure upper airway, radiographic exclusion of midline central nervous system anomalies, and early surgical excision to prevent asphyxia or permanent disfigurement. Perioperative assessment ...
Chien C H - - 1990
Immature mediastinal teratomas are rare, found in only 1% of all mediastinal teratomas; those occurring in the neonatal period are even more rare. A male baby suffering from tachypnea, weak crying and hoarseness since birth was noted, from a chest radiograph, to have a superior mediastinal mass. This mass enlarged ...
Whyte A M - - 1990
We report the case of a rapidly expanding mediastinal and chest wall lipoblastoma in an 11-month old infant. Clinical presentation was respiratory distress and chest radiographs revealed a large soft tissue mass in the anterior mediastinum without specific features. CT scanning demonstrated a mass of principally fat attenuation, with enhancing ...
Tahernia A C - - 1990
Primary tumors of the heart are rare in infancy and childhood. A one-year-old, asymptomatic, male infant with unimpressive physical findings in whom an echocardiogram demonstrated a large, encapsulated, solid fibroma filling the right ventricle without obstruction of either the inflow or outflow tract is presented. Successful complete surgical excision of ...
Kelly M F - - 1990
Large congenital cervical neck masses present major difficulties in management of the neonatal airway at delivery and in the perinatal period. With ultrasound, these lesions can be predicted prenatally. An airway treatment plan can then be formulated and modified in relation to the airway presentation at birth. We describe a ...
Zerella J T - - 1990
Most neonates with cervical or oral-pharyngeal teratomas have airway obstruction and an obvious mass. In previous reports, obstruction of the airway had caused 49 deaths in 164 newborns with cervical teratomas and five deaths in 24 newborns with oral-pharyngeal teratomas. Most were reported before the era of prenatal ultrasound. Cervical ...
Viljoen D L - - 1990
We report on an infant with 7 toes of the left foot in a mirror configuration in association with ipsilateral duplication of the calcaneus and fibula, tibial aplasia, femoral hypoplasia, and a teratomatous sacrococcygeal tumour. The possible pathogenetic mechanisms leading to this limb abnormality are discussed with special emphasis on ...
Neiger R - - 1989
Severe hydrocephalus secondary to a massive teratoma occupying the left lateral ventricle and protruding from the left orbit was diagnosed in a newborn infant. A craniofacial mass had been initially detected during labor by ultrasound examination. The pathophysiology of teratomas and the clinical course and ethical issues in management of ...
Buss E A - - 1989
Chest wall hamartoma is a rare intrathoracic mesenchymal tumor occurring in infants and usually present from birth. The tumor arises from the ribs and is a histologically benign focal overgrowth of normal skeletal elements. Infants often present with respiratory problems. We report a case of a 5-month-old infant with a ...
Langer J C - - 1989
Most sacrococcygeal teratomas diagnosed before birth can be managed by planned delivery and postnatal surgery. However, large tumors early in gestation may result in placentomegaly, hydrops, and fetal death and a preeclampsia-like syndrome in the mother. This chain of events may result from high output cardiac failure in the fetus ...
Benacerraf B R - - 1989
Coarctation of the aorta is a serious heart defect that can be successfully treated if identified early. Actual narrowing of the aortic isthmus is very difficult if not impossible to demonstrate on prenatal sonography; however, the indirect sign of discrepant ventricular sizes (right ventricle [RV] greater than left ventricle [LV]) ...
Sepúlveda W H - - 1989
Teratomas are tumors containing tissues derived from all three germinal cell layers. Most teratomas arise in the sacrococcygeal region, with a reported incidence of 1/40,000 births. During labor, severe dystocia may occur in infants with large tumors if delivered vaginally, with an extremely high fetal morbidity and mortality rate. Reported ...
Strife J L - - 1989
In infants, the site of the aortic arch is frequently inferred from the position of the intrathoracic trachea. We retrospectively reviewed the plain frontal chest radiographs of 72 patients with cyanotic congenital heart disease and right aortic arch documented by cardiac catheterization. In infants, the position of the trachea was ...

Sacrococcygeal teratoma is a rare cause of dystocia. With recent advances in perinatal care, particularly the increasing use of maternal ultrasound, it is unlikely that unexpected dystocia secondary to this tumor will be seen by many physicians. Recent reports of this type of dystocia are rare and infant mortality secondary ...
Larkin D F - - 1988
A rare case of fibrous histiocytoma in an infant is described. The tumour appeared to arise in the medial orbit, invading the ethmoid and maxillary sinuses. Surgical and medical management, and the subsequent clinical course in a 11 year follow-up period are described. Histogenesis of this primary mesenchymal tumour is ...
Johnston P W - - 1988
A newborn infant, surgically treated for a sacrococcygeal teratoma, had serially drawn alpha-fetoproteins before and after surgery. The elevated levels were plotted on the graph of normal range proposed by Tsuchida, and although very high, they still fell within the normal range, which suggested benignancy. Pathology showed mature elements, except ...
Weber H S - - 1988
A case of a massive benign intrapericardial teratoma that presented at two weeks of age with significant respiratory distress is described. In retrospect, it was discovered that this infant had been evaluated by fetal echocardiography while in utero at 20 weeks of gestation due to a maternal history of surgically ...
Cohen A F - - 1987
Nasopharyngeal teratomas are rare neoplasms, often presenting as neonatal airway obstruction. A case is presented of a full-term neonate with a mass which filled the oropharynx, nasopharynx and the entire left nasal cavity and extended through the left nares. Airway obstruction necessitated orotracheal intubation immediately after delivery. Cerebrospinal fluid rhinorrhea ...

The clinical presentation of a congenital mucocele is a blue-gray tense mass located inferior to the medial canthal ligament. The differential diagnosis is that of tumor and encephalocele. Diagnostic modalities such as simple transillumination and ultrasound aid the physician, but dacryocystography confirms the marked lacrimal sac distension. In three infants ...
Eftekhari F - - 1986
A recurrent mediastinal mass, believed to be thymus, in an infant with classic idiopathic histiocytosis-X underwent massive cavitation following chemotherapy. Both the mass and cavitation resolved. The exact nature of development of air inside the mass is not known but communication with the airways or airspaces of the lungs is ...
Kim M S - - 1986
A female infant, younger than any other case in the literature, with ACTH-producing microadenoma of the pituitary is reported. She had full-blown symptoms and signs as well as laboratory evidence of Cushing's disease. The tumor was investigated by histology, immunocytology (avidin-biotin-peroxidase complex technique), and electron microscopy. The possibility that the ...
Young R H - - 1985
Three infants, 3 months of age or younger with abnormal karyotypes and ambiguous genitalia, had gonadal juvenile granulosa cell tumors. Two of the patients had mixed gonadal dysgenesis and the third had an intersexual disorder of undetermined type. Two tumors arose in undescended testes, and the third in an undescended ...
Brown J W - - 1985
The ideal operation for infants with coarctation of the aorta remains controversial. Subclavian flap aortoplasty is the most popular technique for this age group. The 5 to 20% recurrence rate is attributed to regrowth of the coarctation web or inadequate length of the subclavian flap, particularly when the aortic isthmus ...
Kohorn E I - - 1985
A case of endodermal sinus tumor of the infant vagina is reported with long-term survival after successful therapy by surgery, chemotherapy, and radiation. The previous 26 reported cases are reviewed and the problems of therapy and long-term management are discussed. Therapy of these tumors should be monitored by alpha-fetoprotein radioimmunoassay.
Oakley R H - - 1985
Chest wall mesenchymoma is a rare benign tumour arising from the ribs and occurring in infants, being usually present from birth. The few previously documented cases have been of solitary tumours. A 6-week-old infant presented with two separate lesions demonstrating specific radiological signs, and on isotope scanning with Technetium MDP ...
Konno H - - 1985
A 35-day-old hydrocephalic infant was found by autopsy to have a small nodular mass protruding into the aqueductal channel. The mass, approximately 2.5 mm in size along the neuroaxis and 1.9 mm in transverse plane, subependymally occupied the roof of the aqueduct. This was thought to be the cause of ...
Vick C W - - 1985
An infant with a factitious abdominal mass due to splenic displacement by the distended stomach is described. Two other cases of this phenomenon have been previously reported, both in infants and both diagnosed by radionuclide scans and plain radiographs. In our patient, diagnosis was made with ultrasound without the need ...
Serlo W - - 1984
Sacrococcygeal teratomata exceeding 20% of the infant's weight are rare. These tumours often cause problems during delivery such as obstruction and rupture of the tumour. By means of prenatal ultrasound screening programmes this condition can be diagnosed in utero and the delivery can take place safely. When dealing with an ...
