Mucocoele of the Blandin-Nühn glands and teratomas of the tongue are rare in newborn babies. We present what is to our knowledge the first documented case of both at the same time, and describe management and follow up over 12 months after the birth. Prenatal diagnosis defined the treatment plan during delivery to establish an airway for the baby promptly. A normal delivery is possible if the cyst is anterior, and can be punctured during delivery. Delayed excision reduces the possibility of oedema and obstruction of the airway, ensures complete resection, avoids recurrence, and confirms the diagnosis...

Mature cystic teratoma is the most common kind of ovarian germ cell tumor. Malignant transformation is uncommon, with thyroid cancer rarely found. Papillary thyroid microcarcinoma has rarely been described as associated with ovarian teratomas. We report a case of a 34-year-old woman who presented with abdominal pain and an ovarian mass. After surgery, the patient was diagnosed with a follicular variant papillary thyroid microcarcinoma that arose within a mature cystic ovarian teratoma. Based on the small size of the primary lesion and patient preferences, no further treatment was performed...

PURPOSE: α-fetoprotein (AFP) and human chorionic gonadotropin subunit beta (B-HCG) are informative serum biomarkers for the primary diagnosis and follow-up of testicular germ cell cancer (TGCC) patients. About 20% of TGCC patients with a non-seminoma (NS) and about 80% with a seminoma (SE) are, however, negative for these biomarkers. Embryonic stem cell microRNAs (miRs) may serve as promising alternative serum biomarkers. Here we investigated a retrospective series of serum samples from selected TGCC patients who developed a relapse in time to test the possible additional value of the serum-based ampTSmiR test compared to the conventional serum-based protein biomarkers for follow-up...

A 67-year-old uniparous woman had undergone surgery for acute perforated gastric ulcer 10 years prior to the current presentation. Although abdominal computed tomography (CT) performed at that point had revealed a mature cystic teratoma measuring 6 cm in diameter in the right ovary, it was left untreated. She visited the department of surgery at our hospital with chief complaints of appetite loss, nausea, and vomiting that had persisted for the prior two weeks. She was admitted with a diagnosis of ileus attributed to an abdominal incisional hernia...

Human pluripotent stem cells (hPSCs), including embryonic stem cells (hESCs) and induced pluripotent stem cells (hiPSCs), have great potential as an unlimited donor source for cell-based therapeutics. The risk of teratoma formation from residual undifferentiated cells, however, remains a critical barrier to the clinical application of these cells. Herein we describe external beam radiation therapy (EBRT) as an attractive option for the treatment of this iatrogenic growth. We present the evidence that EBRT is effective in arresting growth of hESC-derived teratomas in vivo at day 28 post-implantation by utilizing a microCT irradiator capable of targeted treatment in small animals...

Myocardial infarction remains one of the top leading causes of death in the world and the damage sustained in the heart eventually develops into heart failure. Limited conventional treatment options due to the inability of the myocardium to regenerate after injury and shortage of organ donors require the development of alternative therapies to repair the damaged myocardium. Current efforts in repairing damage after myocardial infarction concentrates on using biologically derived molecules such as growth factors or stem cells, which carry risks of serious side effects including the formation of teratomas...

We report a case of a 37-year old female with a mature teratoma of the uterine corpus presented by metrorrhagia. Grossly, the tumor was polypoid without apparent invasion into the myometrium. Microscopically, the tumor consisted of disorganized mature neural tissue intermingled with nodular foci of cartilaginous tissue, groups of seromucionous glands and ciliated columnar respiratory epithelium. Fifteen months after the diagnosis, the patient showed no signs of tumor relapse. Then she was lost for a follow-up...

Molecular imaging is indispensable for determining the fate and persistence of engrafted stem cells. Standard strategies for transgene induction involve the use of viral vectors prone to silencing and insertional mutagenesis or the use of non-human genes. We used zinc finger nucleases (ZFN) to induce stable expression of human imaging reporter genes into the safe harbor locus adeno-associated virus integration site 1 (AAVS1) in human embryonic stem cells (ESC). Plasmids were generated carrying reporter genes for fluorescence, bioluminescence imaging (BLI), and human positron emission tomography (PET) reporter genes...

Oral foregut duplication cysts are extremely rare lesions with approximately 57 cases reported. They are congenital cysts, located in the anterior or ventral tongue, and occur predominantly in males. They are lined by one or more types of epithelia which is limited to gastric, intestinal or respiratory epithelium. The differential diagnosis includes lymphangioma, hemangioma, ranula, epidermoid cyst, teratoma and less likely a malignant process.

BACKGROUND: Mechanical stimuli play important roles in the proliferation and differentiation of adult stem cells. However, few studies on their effects on induced pluripotent stem cells (iPSCs) have been published. METHODS: Human dermal fibroblasts were seeded onto flexible membrane-bottom plates, and infected with retrovirus expressing the four reprogramming factors OCT4, SOX2, KLF, and c-MYC (OSKM). The cells were subjected to equiaxial stretching (3% or 8% for 2, 4, or 7 days) and seeded on feeder cells (STO)...

Rarely, liver tissue can be seen in the umbilical cord, where it is thought to result from ectopic localization during embryogenesis. The placental parenchyma is also a rare site for this occurrence. The exact pathophysiology of ectopic liver in the placenta is unknown. It has been considered that aberrant migration or displacement of cells from the developing hepatic buds leads to ectopic liver formation, including groups of liver cells that become entrapped in the foregut as the diaphragm closes. Additional hypotheses put forward have included monodermal teratoma and hepatocellular adenoma...

The purpose of this study was to determine the expression and potential clinical role of epithelial-to-mesenchymal transition (EMT)-related factors in malignant ovarian germ cell tumors (MOGCT). Protein expression of E-cadherin, N-cadherin, P-cadherin, Zeb1, HMGA2, and vimentin by immunohistochemistry was analyzed in 42 MOGCT from patients treated in Norway during the period 1981-2001. Expression was analyzed for association with clinicopathologic parameters. E-cadherin (p = 0.016) and HMGA2 (p = 0.002) expression was significantly higher in immature teratomas and yolk sac tumors compared with dysgerminomas...

BACKGROUND: Currarino syndrome (CS) is a rare genetic condition that presents with the defining triad of anorectal malformations, sacral bone deformations, and presacral masses, which may include teratoma. Neurosurgeons are involved in the surgical treatment of anterior meningoceles, which are often associated with this condition. The accepted surgical treatment is a staged anterior-posterior resection of the presacral mass and obliteration of the anterior meningocele. CASE DESCRIPTION: This case involved a 36-year-old female who presented with late onset of symptoms attributed to CS (e...

AIMS: Accurate histologic diagnosis and classification of germ cell tumors (GCTs) is key to informing successful therapeutic and surveillance strategy. Modern therapeutic approach for yolk sac tumor (YST) is highly curative. Because YST takes on a large morphologic spectrum, it can be confused for other GCT subtypes as well as somatic carcinomas, particularly when YST presents in an extragonadal or a metastatic setting. Currently available immunohistochemical markers are limited by suboptimal sensitivity and specificity...

A 40-year-old man complaining of abdominal distention was referred to our hospital. Computed tomography of the abdomen demonstrated a very large abdominal mass with fat and calcification. The size of the mass rapidly increased from 30cm to 40cm over two weeks. The tumor was removed and diagnosed by pathological examination to be a retroperitoneal mature cystic teratoma that contained a 40-cm long, mature intestinal tract-like cyst, together with bone marrow and fat. The rapid growth of the tumor may have been caused by an increased secretion in the cyst...
