Gastric teratoma is a very rare tumor, accounting for less than 1 % of all teratomas in infants and children. Melena or upper gastrointestinal tract bleeding in newborns and infants is a rare event and is usually caused by a benign lesion. Gastric teratoma has been reported as a cause of gastrointestinal bleeding on a few occasions. As gastric teratomas generally present as a palpable abdominal mass, more aggressive solid masses of childhood must be excluded. We present intramural extension of gastric teratoma presented as symptom of gastric outlet obstruction and melena...

INTRODUCTION: Neck masses occurring in the neonatal period and early infancy consist of vascular tumors, vascular malformations, benign and malignant soft tissue tumors and other developmental lesions. Although some lesions can be diagnosed on clinical grounds, others can only be diagnosed by imaging. Beyond diagnosis, imaging plays a significant role in evaluating the location and extent of a lesion for possible intervention. METHODS AND MATERIALS: Clinical series descriptive study with a retrospective examination of neonates with masses of the neck...

BACKGROUND: Adenocorticotropic hormone (ACTH)-dependent Cushing's syndrome in infancy is extremely rare. We describe the case of a sacro-coccygeal ectopic ACTH-secreting immature teratoma in an infant who also presented the triad of defects characteristic of Currarino syndrome. CASE PRESENTATION: A girl was born with a large immature teratoma in the sacro-coccygeal region associated with anal atresia. At the age of 7 days, the concentration of α-fetoprotein (AFP) was above the age-specific normal range...

A three-month-old female infant presented with abdominal distention for 2 months. A large palpable mass in right upper quadrant was noted on physical exam. Abdominal ultrasound revealed a large heterogeneous mass with multiple cystic components. Mass was surgically excised and pathology was consistent with mature adrenal teratoma. Teratoma is a germ cell tumor mainly found in gonadal tissues. Occurrence of adrenal gland teratoma in children is very rare with less than 10 pediatric case reports in English literature...

Extralobar sequestrations constitute a rare form of congenital pulmonary airway malformations that are difficult to diagnose. Here, we report a rare case of a localized extralobar sequestration in the right superior portion of the mediastinum accompanied by congenital cystic adenomatoid malformation.A 19-year-old man presented with a right upper mediastinal mass that was detected using chest radiography, had a history of left spontaneous pneumothorax, and had undergone a bullectomy 4 years previously.The initial diagnosis included a mature teratoma and a bronchogenic cyst in the mediastinum; however, the presence of a cystic mass in the right upper lobe of the lung prompted further examination...

Although immature teratoma of the ovary is a rare disease, its pathologic grading, especially between low-grade (grade 1) and high-grade (grade 2 or 3) immature teratomas, is important for optimal therapy and prognosis. This grading, however, is currently solely dependent on quantitation of neuroepithelial components as judged by subjective assessments. As we have recently successfully studied the maturation of vascular smooth muscle cells (SMCs) in other organs using an h-caldesmon to α-smooth muscle actin (α-SMA) ratio, we decided to use this ratio to investigate a potential link between teratoma grade and SMC maturation, in combination with Ki-67 index...

Epigenetic variation with age is one of the most important hallmarks of aging. Resetting or repairing the epigenome of aging cells in intact animals may rejuvenate the cells and perhaps the entire organism. In fact, differentiated adult cells, which by definition have undergone some epigenetic changes, are capable of being rejuvenated and reprogrammed to create pluripotent stem cells and viable cloned animals. Apparently, such reprogramming is capable of completely resetting the epigenome. However, attempts to fully reprogram differentiated cells in adult animals have failed in part because reprogramming leads to formation of teratomas...

Foetal magnetic resonance imaging (MRI) plays an increasingly important role in the diagnosis of foetal abnormalities. Over the years, we have successfully applied bi-parametric MRI (bp-MRI) to the following obstetric conditions: (1) neurologic vascular diseases; (2) assessment of lung parenchyma maturation; (3) renal pathologies, such as polycystic kidney, suspected renal infarction, unilateral or bilateral renal agenesis; (4) placental pathologies, as twin-twin transfusion syndrome or placenta accreta; (5) benignant and malignant congenital tumours or cysts of the liver, such as haemangioendothelioma, hepatoblastoma or metastatic neuroblastoma, of the kidney (e...

Teratoma is a rare tumor, containing structures originating from all three germinal layers. The most frequent location of teratoma is the gonads. Orbital teratoma is extremely rare. In 1969, Jensen reported that only 40 cases of orbital teratoma existed in the world. We describe a rare case of orbital teratoma in a 15-day girl who presented with marked proptosis of the left eye. The eyeball was embedded within the mass that could be seen all around the globe. Orbitectomy was performed with the impression of retinoblastoma...

Primary primitive neuroectodermal tumor (PNET) of the female genital tract is rare, and its proper classification remains unclear. The clinical, histologic, and immunophenotypic features as well as EWSR1 rearrangement status of 19 gynecologic PNETs, including 10 ovarian, 8 uterine, and 1 vulvar tumors, are herein reported. Patient age ranged from 12 to 68 years, with a median age of 20 and 51 years among those with ovarian and uterine PNETs, respectively. Morphologic features of central nervous system (CNS) tumors were seen in 15 PNETs, including 9 medulloblastomas, 3 ependymomas, 2 medulloepitheliomas, and 1 glioblastoma, consistent with central PNET...

Cystic trophoblastic tumor (CTT) has been described in postchemotherapy retroperitoneal lymph node dissections of patients with testicular germ cell tumors. Prognostically, this lesion is similar to teratoma and no further treatment is required after surgery in the absence of other components. CTT has not, however, been reported in the testis. We identified 14 CTTs in the treated (4) and untreated (9; no information for 1 patient) testes of patients 15 to 43 years old (median, 25) with mixed germ cell tumors...

Mature cystic teratoma is one of the most common kinds of ovarian tumor, and immature teratoma is a rare tumor, representing less than 1% of all ovarian teratomas. Although there are some reports about familial occurrences of ovarian tumors, literature concerning the clinical cases of monozygotic twins is rare. We report the 5-year clinical courses of a 12-year-old Japanese girl with a recurrent bilateral ovarian mature teratoma and her monozygotic twin with a unilateral ovarian mature teratoma and contralateral ovarian immature teratoma...

BACKGROUND: Mature cystic teratomas are usually found in the ovaries. They are bilateral in 10 to 15% of cases and multiple cystic teratomas may be present in one ovary. The aim of this study is to clarify if development of mature cystic teratomas of the ovaries in a single host is metachronous or due to autoimplant or recurrence. CASE PRESENTATION: We report a woman with bilateral mature cystic teratomas of the ovaries. DNA profiles of these teratomas were investigated via short tandem repeat (STR) analysis and methylation statuses were determined via methylation sensitive multiplex ligation-dependent probe amplification methods...

BACKGROUND: Large mediastinal teratomas in the fetus are rare and can present with direct compression of intrathoracic structures as well as pericardial and pleural effusions. Mediastinal fetal teratoma may be detected as a mass in the chest during a routine prenatal ultrasound. Because of the pressure on mediastinal structures it may result in non-immune fetal hydrops and polyhydramnios. The development of hydrops may lead to fetal demise. Timely obstetric and surgical removal is important to improve survival in this patient population...
