Sample records for abdominal teratoma renal

  1. Mature Cystic Renal Teratoma

    Teratomas are rare germline tumors that originate from one or more embryonic germ cell layers. Teratoma of the kidney is extremely rare, and less than 30 cases of primary intrarenal teratomas have been published to date. We report the main radiologic features of an unusual case of mature cystic teratoma arising from the left kidney in a two-year-old boy. A left-sided abdominal mass was detected on physical examination and B-Mod Ultrasound (US) examination revealed a heterogeneous mass with central cystic component. Computed tomography (CT) demonstrated a lobulated, heterogeneous, hypodense mass extending craniocaudally from the splenic hilum to the level of the left iliac fossa. Nephrectomy was performed and a large, fatty mass arising from the left kidney was excised. The final pathologic diagnosis was confirmed as cystic renal teratoma

    Abstract Teratomas are neoplasms that arise from pluripotent cells and can differentiate along one or more embryonic germ lines. Renal teratoma is an exceedingly rare condition. Teratomas commonly arise in the gonads, sacrococcygeal region, pineal gland, and retroperitoneum. They present mainly as an abdominal mass with few other symptoms. Majority of the tumors are benign, situated on the left side and para renal, occasional lesions are bilateral. If diagnosed early, they are amenable to cur...

    Primary upper abdominal teratomas are extremely rare tumours, most commonly arising in infants. The radiological literature relating to them is sparse. Surgical resection is difficult due to distortion of the vascular anatomy. To reassess the value of preoperative imaging with specific reference to the presence/absence of typical features of teratoma, anatomical location and adjacent vascular anatomy. The histopathology database was used to identify infants with upper abdominal teratoma. Pathological, surgical and radiological data were reviewed. The search of the database identified 12 infants (10 girls, 2 boys) with an abdominal/retroperitoneal teratoma during the period 1993 to 2006. All teratomas were benign. In the majority of infants, typical radiological features of teratoma were demonstrated (fat, calcium). Identification of the major abdominal vessels on CT scan (most commonly the inferior vena cava) was not possible in all infants. Distortion (and commonly encasement) of the adjacent major abdominal vessels was usually evident. Upper abdominal teratomas in infants have typical radiological features. Preoperative delineation of the major vascular anatomy is often imprecise. Significant distortion of vascular anatomy was present in all infants and awareness of this feature impacts on surgical planning. (orig.)

    2013-01-01

    Retroperitoneum is a relatively uncommon site for pediatric teratomas. Rarely, such tumors can have an intraspinal extension and few cases of retroperitoneal teratomas associated with spinal dysraphism have been reported. Teratomas consist of tissues arising from all three embryonic layers. However, mature renal tissues in the form of glomeruli and tubules are sparingly found in teratomas. A 15-day-old female presented with spina bifida occulta and on evaluation a cystic presacral mass was de...

    A 74-year-old hypertensive woman presented with abdominal discomfort and a pulsatile abdominal mass. Anterior abdominal angiography during cardiac blood pool, and renal scintigraphic imaging demonstrated a large abdominal aortic aneurysm. 1, 2 Before endovascular repair with an aortoiliac endograft, the abdominal aneurysm measured 7.5 x 7.0 cm on abdominal computed tomography. This study demonstrates that a suspected abdominal aortic aneurysm can be confirmed using the addition of anterior abdominal imaging with normal posterior imaging at the time of renal scintigraphy.

  8. Primary retroperitoneal teratoma and crossed fused renal ectopia with turner's syndrome -a case report-

    In 1938, Turner described a clinical entity in phenotype females characterized by sexual infantilism, congenital webbed neck and cubitus valgus. After then, the occurrence of renal anomalies in patients with Turner's syndrome has been recognized. Associated crossed fused renal ectopia is very rare. Primary retroperitoneal teratoma is also rare and usually during childhood. The authors report a case of primary retroperitoneal teratoma and crossed fused renal ectopia with Turner's syndrome (mosaic type). The clinical, pathological and radiographical findings are reviewed

  9. Intrarenal mature cystic teratoma associated with renal dysplasia: case report and literature review.

    Otani, M; Tsujimoto, S; Miura, M; Nagashima, Y

    2001-07-01

    We report a case of intrarenal teratoma in a 6-year-old boy. Two years before his operation, multicystic masses had been found in the left side of his abdomen. In the operation, three main cystic masses were located in the upper and lower poles of the left kidney, which were removed in pieces. Histologically, the cyst wall was lined mainly with keratinizing squamous epithelium with hair follicles, shafts and sebaceous glands. The adjacent renal parenchyma showed atrophy, with partially dysplastic and angiomyolipoma-like lesions. Based on these findings, the lesion was diagnosed as mature cystic teratoma of dermoid cyst type. Extragonadal teratoma occurs predominantly along the median line of the body. Intrarenal teratoma is extremely rare; however, it should be distinguished from teratoid Wilms' tumor and other renal cystic lesions. PMID:11472570

    Full Text Available Amongst the varied, diverse causes of intraabdominal masses in infancy and early childhood, gastric teratomas (GTs account for a very small proportion. A worldwide literature search reveals only around one hundred cases of GT and also supports the fact that its preoperative diagnosis remains elusive. Here we report the case of a two-month-old male who presented to the pediatric surgery outpatient department of Kasturba Medical College and Hospital, Karnataka, India, with progressive distension of abdomen since birth. Clinically, a large firm, non-mobile and non-tender mass involving all four quadrants of the abdomen was seen. Ultrasound revealed a large solid-cystic mass with internal septations extending from the epigastrium up to the pelvis. Computed tomography revealed a large intraperitoneal fat containing solid-cystic mass lesion showing curvilinear and chunky areas of calcification, with the mass focally indenting the posterior gastric wall and showing focal polypoidal intragastric extension. Exploratory laparotomy revealed a large cystic tumor with a solid component, arising from lesser curvature of the stomach, showing focal intraluminal extension across the posterior gastric wall, and occupying the whole lesser sac and abdominal cavity. The tumor was excised in toto along with the body of the stomach. Histopathological examination showed mature tissue derived from all three germ cell layers and confirmed the diagnosis of mature gastric teratoma. The patient was disease free at one-year follow-up.

  11. Bilateral Ovarian Teratoma: One Parasitic Twisted In-situ and Another Parasitic at the Hepato Renal Space.

    Chitrakar, N S; Suwal, S; Neupane, S

    2015-01-01

    Parasitic ovarian dermoid cysts are very rare. We report a rare case of bilateral ovarian dermoid cysts with parasitic teratoma at the hepato renal space measuring 11x11x6 cm while the other was twisted measuring 10x6x5 cm.Right ovary and tube were absent. The mass found at the hepato renal space was surrounded by and adherent to the omentum with viable tubal fimbria like structure at upper surface. Histopathologically both masses were confirmed as mature ovarian teratoma. The etiology of parasitic teratoma would be due to torsion followed by autoamputation and reimplantation of the right ovarian dermoid cyst. PMID:26744205

  12. Late renal function following whole abdominal irradiation

    Sixty patients treated with whole abdominal radiotherapy who had remained disease-free since completion of treatment participated in a study to assess the late clinical and biochemical effects of bilateral renal irradiation. Minimum follow-up was 5 years with a maximum of 20 years and a median of 9 years. Fifty-two patients in the study group were treated for primary ovarian cancer. Seven had non-Hodgkins lymphoma arising in the gastrointestinal tract and one patient had a carcinoid tumour arising in small bowel. None of the patients received chemotherapy. Abdominal radiation was given using an open beam technique to a mean dose of 22.92 Gy (range 6.68-27.54 Gy) in 1.02 to 1.25 Gy fractions treated once daily. Posterior kidney shields were used in order to limit the renal dose to <20 Gy. Mean radiation dose to both kidneys (retrospectively calculated) was 19.28 Gy (range 6.68-22.99 Gy). Patients ranged in age from 32-81 years with a median of 61 years. No patient had clinical evidence of renal impairment. Nine patients were hypertensive prior to radiotherapy and a further five patients became hypertensive after treatment. Serum creatinine values ranged from 44-123 μmol/l, with a mean of 87 μmol/l. Creatinine clearance ranged from 0.61-2.38 ml/s (mean 1.28 ml/s). Tubular function tests revealed one borderline high 24-h protein excretion and normal 24-h phosphorous and uric acid. Using a multiple linear regression analysis with creatinine clearance as the endpoint, age was the only significant variable (P < 0.00001) and renal dose and interval from treatment were not independently significant. There was no evidence of late renal toxicity more than 5 years after whole abdominal radiotherapy delivered with this technique and dose/fractionation schedule, and using the clinical and biochemical endpoints assessed in this study

    Full Text Available Introduction. Kidney anomalies present a challenge even for the most experienced vascular surgeon in the reconstruction of the aortoilliac segment. The most significant anomalies described in the surgery of the aortoilliac segment are a horse-shoe and ectopic kidney. Objective. The aim of this retrospective study was to analyze experience on 40 patients with renal anomalies, who underwent surgery of the aortoilliac segment and to determine attitudes on conventional surgical treatment. Methods. In the period from 1992 to 2009, at the Clinic for Vascular Surgery of the Clinical Centre of Belgrade we operated on 40 patients with renal anomalies and aortic disease (aneurysmatic and obstructive. The retrospective analysis involved standard epidemiological data of each patient (gender, age, risk factors for atherosclerosis, type of anomaly, type of aortic disease, presurgical parameter values of renal function, type of surgical approach (laparatomy or retroperitoneal approach, classification of the renal isthmus, reimplantation of renal arteries and perioperative morbidity and mortality. Results. Twenty patients were males In 30 (70% patients we diagnosed a horse-shoe kidney and in 10 (30% ectopic kidney. In the cases of ruptured aneurysm of the abdominal aorta the diagnosis was made by ultrasound findings. Pre-surgically, renal anomalies were confirmed in all patients, except in those with a ruptured aneurysm who underwent urgent surgery. In all patients we applied medial laparatomy, except in those with a thoracoabdominal aneurysm type IV, when the retroperitonal approach was necessary. On average the patients were under follow-up for 6.2 years (from 6 months to 17 years. Conclusion. Under our conditions, the so-called double clamp technique with the preservation of the kidney gave best results in the patients with renal anomalies and aortic disease.

    We present a case of a teratoma with somatic type malignancy (TSM) in the form of papillary renal cell carcinoma (pRCC) within supraclavicular and retroperitoneal lymph node metastases of a testicular pure teratoma. Resection of both masses revealed a teratoma without any other germ cell tumor component. A papillary carcinoma component was also detected intermingled with the teratomatous elements. The carcinoma cells displayed eosinophilic cytoplasm and prominent nucleoli. Groups of foamy histiocytes in the fibrovascular cores was a striking finding that brought pRCC to mind. Immunoreactivity for CK7, PAX8, AMACR, CD10, napsin, and vimentin along with morphologic findings confirmed renal cell differentiation. No radiological evidence of a primary renal cell carcinoma was found in the kidney. Consequently, pRCC arising in a teratoma was diagnosed. TSM is described as teratoma with a malignant component that is typically encountered in other organs and tissues. TSM in the form of pRCC is an extremely rare entity. Our case is the second example of a testicular germ cell tumor metastasis with a somatic malignancy in the form of pRCC. In conclusion, carcinomas of renal cell differentiation should be kept in mind as a rare form of TSM, especially in metastatic germ cell tumors. PMID:26936856

    Retroperitonal teratomas are rare. We report on a case of a retroperitoneal secondary localisation of a gonadal teratoma in a patient who had developed primary testicular teratoma 12 years previously. The retroperitoneal mass was detected with an abdominal CT requested for the management of a non-specific abdominal pain. CT and MRI examinations showed cystic retroperitoneal masses combined with calcifications and peripheral enhancement. Review of the literature is presented, including the common differential diagnoses to be considered. PMID:22338389

  18. Giant intra-abdominal mature cystic teratoma (dermoid cyst) in an adult man, with male genitourinary tissue including prostatic and penile elements.

    2016-08-01

    We describe a case of a giant intra-abdominal mature cystic teratoma in a 36-year-old man, which comprised typical features of differentiated teratoma/dermoid cyst but which contained a macroscopic rudimentary penis, with vasoformative erectile tissue-like structures consistent with corpora cavernosa, as well as scrotal-type skin and prostatic tissue. The genitourinary structures were well formed both grossly and microscopically and sharply demarcated from the rest of the neoplasm, which comprised typical differentiated teratoma, without any other macroscopic foci of organoid differentiation or of other histologic differentiation. The plasticity of the cells of differentiated teratoma, which enables it to undergo multidirectional differentiation, is well recognized, but the factors determining this distinct path of differentiation remain to be established.

    The patient was an 82-year-old man who was found to have a juxtarenal abdominal aortic aneurysm accompanied by a circumaortic left renal vein (CLRV). During dissection of the proximal anastomosis site the CLRV was injured, but was successfully repaired. A graft implantation was performed below the renal arteries. The incidence of CLRV is thought to be rare, however it is found in 7% of cadavers donated for anatomy. CLRV may cause unexpected bleeding by inadvertent dissection of the abdominal ...

  4. Renal Atrophy Secondary to Chemoradiotherapy of Abdominal Malignancies

    Purpose: To identify factors predictive of renal atrophy after chemoradiotherapy of gastrointestinal malignancies. Methods and Materials: Patients who received chemotherapy and abdominal radiotherapy (RT) between 2002 and 2008 were identified for this study evaluating change in kidney size and function after RT. Imaging and biochemical data were obtained before and after RT in 6-month intervals. Kidney size was defined by craniocaudal measurement on CT images. The primarily irradiated kidney (PK) was defined as the kidney that received the greater mean kidney dose. Receiver operating characteristic (ROC) curves were generated to predict risk for renal atrophy. Results: Of 130 patients, median age was 64 years, and 51.5% were male. Most primary disease sites were pancreas and periampullary tumors (77.7%). Median follow-up was 9.4 months. Creatinine clearance declined 20.89%, and size of the PK decreased 4.67% 1 year after completion of chemoradiation. Compensatory hypertrophy of the non-PK was not seen. Percentage volumes of the PK receiving ≥10 Gy (V10), 15 Gy (V15), and 20 Gy (V20) were significantly associated with renal atrophy 1 year after RT (p = 0.0030, 0.0029, and 0.0028, respectively). Areas under the ROC curves for V10, V15, and V20 to predict >5% decrease in PK size were 0.760, 0.760, and 0.762, respectively. Conclusions: Significant detriments in PK size and renal function were seen after abdominal RT. The V10, V15, and V20 were predictive of risk for PK atrophy 1 year after RT. Analyses suggest the association of lower-dose renal irradiation with subsequent development of renal atrophy.

    Gastric Teratoma is an extremely rare neoplasm seen in children. It is mostly benign and predominantly seen in males presenting with an abdominal mass. The lung and stomach are very unusual sites for teratoma. Gastric teratoma accounts for less than 1% of all teratomas, less than 100 cases are reported in literature. We report a case in a 20-day-old infant who presented with large abdominal mass; our case is an addition to the few limited known gastric teratomas reported in the world literature.

    2014-01-01

    We report a case in which an immature teratoma developed following three previous resections for mature cystic teratomas. The patient was a 26-year-old nulliparous woman with a regular menstrual cycle. Twelve years earlier, she had consulted a pediatrician for complaints of lower abdominal pain. Bilateral cystic teratomas were suspected and she underwent a left salpingo-oophorectomy and a right cystectomy laparoscopically, and bilateral mature cystic teratomas were diagnosed histologically. She underwent a right cystectomy twice afterwards and mature cystic teratomas were diagnosed. Three years after the third surgery, a regular checkup performed annually for ovarian cyst recurrence revealed a 9.3 cm ovarian cyst by ultrasonography without marker elevation or complaint of symptoms. Magnetic resonance imaging (MRI) showed a 10 cm multilocular cyst, including a part with heterogeneous medium and high-signal intensity on T2-weighted images, which revealed enhancement on dynamic contrast-enhanced MRI unlike the previous images. Ovarian tumors, including immature teratomas and malignancy, were considered. She had a strong wish to undergo laparoscopic surgery. She was diagnosed with an immature teratoma, grade 1 of the right ovary. Although the frequency of recurrence of immature teratomas after resection of mature cystic teratomas is very low, regular checkups are necessary because there may be no associated symptoms.

    For congenital teratomas, oropharyngeal cavity is one of the rarest sites (2% of all teratomas). They are rarely picked up by prenatal ultrasonography. Postnatally, newborns present with respiratory distress and at this point role of pediatricians is very crucial in establishing secure airway after which they need to be carefully evaluated and surgically managed. We present a female neonate with palatal teratoma which was treated successfully with surgery.

    Vascular disorders affecting the kidneys are either acquired or congenital. Included in this category are common multiplicity of renal arteries, the rare arteriovenous malformation, stresses due to fibromuscular disease or atherosclerosis including abdominal aortic aneurysms, arterial thrombosis, venous thrombosis, and infarction. In contrast to the group of cystic and neoplastic kidneys where scintigraphic or pathologic are not diagnostic, scintigraphic or pathologic anatomy in vascular disease is often diagnostic by nuclear medicine techniques. The authors present an interesting case of evaluation of acute renal failure in a patient abdominal aortic aneurysmectomy and axillo-bifemoral bypass graft.

In contrast to the group of cystic and neoplastic kidneys where scintigraphic or pathologic are not diagnostic, scintigraphic or pathologic anatomy in vascular disease is often diagnostic by nuclear medicine techniques. The authors present an interesting case of evaluation of acute renal failure in a patient abdominal aortic aneurysmectomy and axillo-bifemoral bypass graft

    Full Text Available Questions1. What is the incidence of sacrococcygeal teratoma? 2. What factors are considered to modify the biologic behaviour of sacrococcygeal teratomas? 3. Discuss antenatal management of sacrococcygeal teratoma?.......1. Incidence is said to vary from 1 per 50,000 live births to 1 in 35,000 live births. But a population based study from Newcastle upon Tyne, UK has found the incidence to be 1 in 27,000 live births [1]. 2. Various interdependent clinical and epidemiologic variables such as the age at diagnosis, sex, tumor site, histology which all correlate to different cytogenetic and molecular biologic aberrations; are considered to modify biologic behaviour of teratomas. Size of a sacrococcygeal teratoma (average 8 cm, range 1 to 30 cm does not predict its biological behaviour. Histological grading of SCT does not seem to correlate with prognosis [2]. 3. Antenatal diagnosis is being more commonly made nowadays. Gabra et al found that before 1988, 2 of 18 were diagnosed antenatally compared with 8 of 15 between 1988 and 2001 [1]. .......

    Hudorović, Narcis; Lovricević, Ivo; Brkić, Petar; Ahel, Zaky; Vicić-Hudorović, Visnja

    2011-09-01

    The objective of this review is to assess the incidence of postoperative acute renal failure that necessitates the application of hemofiltration and to determine the factors that influence the outcome in patients undergoing surgical repair of abdominal aortic aneurysm. In addition, the review aims to assess the outcomes of postoperative early hemofiltration as compared to late intensive hemofiltration. Different forms of renal replacement therapies for use in abdominal aortic aneurysm surgery patients are discussed. Electronic literature searches were performed using Pubmed, Medline, Embase, Sumsearch, Cinahil, The Cochrane Central Register of Controlled Trials and Excerpta Medica. The search identified 419 potentially eligible studies, of which 119 were excluded based on the title and abstract. Of the remaining 300 studies, full articles were collected and re-evaluated. Forty-five articles satisfied our inclusion criteria, of which only 12 were of the IA Level of evidence. The search results indicated that the underlying disease, its severity and stage, the etiology of acute renal failure, clinical and hemodynamic status of the patient, the resources available, and different costs of therapy might all influence the choice of the renal replacement therapy strategy. However, clear guidelines on renal replacement therapy duration are still lacking. Moreover, it is not known whether in acute renal failure patients undergoing abdominal aortic aneurysm surgery, renal replacement therapy modalities can eliminate significant amounts of clinically relevant inflammatory mediators. This review gives current information available in the literature on the possible mechanisms underlying acute renal failure and recent developments in continuous renal replacement treatment modalities.

  17. Acute renal failure due to abdominal compartment syndrome: report on four cases and literature review

    Cleva Roberto de

    2001-01-01

    Full Text Available We report on 4 cases of abdominal compartment syndrome complicated by acute renal failure that were promptly reversed by different abdominal decompression methods. Case 1: A 57-year-old obese woman in the post-operative period after giant incisional hernia correction with an intra-abdominal pressure of 24 mm Hg. She was sedated and curarized, and the intra-abdominal pressure fell to 15 mm Hg. Case 2: A 73-year-old woman with acute inflammatory abdomen was undergoing exploratory laparotomy when a hypertensive pneumoperitoneum was noticed. During the surgery, enhancement of urinary output was observed. Case 3: An 18-year-old man who underwent hepatectomy and developed coagulopathy and hepatic bleeding that required abdominal packing, developed oliguria with a transvesical intra-abdominal pressure of 22 mm Hg. During reoperation, the compresses were removed with a prompt improvement in urinary flow. Case 4: A 46-year-old man with hepatic cirrhosis was admitted after incisional hernia repair with intra-abdominal pressure of 16 mm Hg. After paracentesis, the intra-abdominal pressure fell to 11 mm Hg.

  18. RUPTURE OF ABDOMINAL AORTIC ANEURYSM IN RENAL TRANSPLANT PATIENT

    B. V. Fadin

    2012-05-01

    Full Text Available The purpose of this article was to report our first experience in surgical treatment of aortic aneurism rupture in patient of 55 years old with renal transplant. Aortic aneurism rupture always associated with high mortality, and urgent operative procedure is also rather complicative and has also in bad anatomical conditions. The expectation of good collateral circulation for renal transplant, quick cross-clamp time and easy graft replacement may not always be the case. We believe that trans- planted kidney should be protected when ever feasible, especially in urgent procedure.

    2012-01-01

    Full Text Available Introduction. Mature teratomas (benign cystic teratomas or dermoid cysts are among the most common ovarian tumours; however, teratomas of the omentum and mesentery are extremely rare. Teratoma in the intraperitoneal cavity is uncommon and atypical, and it is even more uncommon in adulthood. Case Outline. An 82-year-old female was admitted to our department with clinical signs of abdominal tumour. The ultrasound scan and preoperative laboratory tests were done. Explorative laparotomy revealed tumour with torsion on its pedicle at the greater omentum. After removal of the mass and the incision a tooth and hair were found, characteristics of teratoma. Conclusion. The excision was very effective and also definitive treatment for this case. The patient recovered well and was discharged 3 days later. The patient probably carried the tumour all her life asymptomatically until admission.

  1. Ultrasonographic Findings of Pediatric Retroperitoneal Teratoma

    Kim, In One; Yeon, Kyung Mo [Seoul National University College of Medicine, Seoul (Korea, Republic of)

    1987-12-15

    Retroperitoneal teratoma is a congenital retroperitoneal tumor containing three germ layers, with no anatomical connections to reproperitoneal organs. The ultrasonographic findings of 9 pediatric retroperitoneal teratomas were analysed. The most characteristic ultrasonographic pattern was coplex echogenic tumor showing cystic mass containing variable pattern of solid echoes due to calcification, fatty component or other solid component. Calcifications showed high spotty echoes with posterior shadowing and fatty component showed very refractile echoes protruding into the cystic portion. In addition to plain abdominal radiography, the ultrasonographic characteristics of retroperitoneal teratoma is expected to improve diagnostic accuracy

  2. Epignathus Teratoma.

    Akhtar, Rabia; Riffat, Mamoona; Mehmood, Zainab

    2016-05-01

    An epignathus is an extremely rare form of oropharyngeal teratoma that arises from the oral cavity, most commonly from the palate and is associated with a high mortality, secondary to airway obstruction in the neonatal period. We present a case of epignathus, diagnosed on antenatal ultrasound as teratoma. It was associated with polyhydramnios. The mother had presented with preterm labour at 27 weeks of gestation. Astillborn baby girl with a large epignathus was expelled spontaneously 2 hours after admission. Accurate prenatal diagnosis of the condition can be done by prenatal ultrasound including colour Doppler ultrasound, three dimensional ultrasound and MRI. The patient can be managed by EXIT (ex uterointrapartum treatment) procedure immediately after birth. Alternatively, the airway can be secured initially and a more complicated surgery can be undertaken once the patient is stable. Foetal surgery is another theoretical possibility. PMID:27225155

  3. Non-contrast-enhanced renal and abdominal MR angiography using velocity-selective inversion preparation.

    Shin, Taehoon; Worters, Pauline W; Hu, Bob S; Nishimura, Dwight G

    2013-05-01

    Non-contrast-enhanced MR angiography is a promising alternative to the established contrast-enhanced approach as it reduces patient discomfort and examination costs and avoids the risk of nephrogenic systemic fibrosis. Inflow-sensitive slab-selective inversion recovery imaging has been used with great promise, particularly for abdominal applications, but has limited craniocaudal coverage due to inflow time constraints. In this work, a new non-contrast-enhanced MR angiography method using velocity-selective inversion preparation is developed and applied to renal and abdominal angiography. Based on the excitation k-space formalism and Shinnar-Le-Roux transform, a velocity-selective excitation pulse is designed that inverts stationary tissues and venous blood while preserving inferiorly flowing arterial blood. As the magnetization of the arterial blood in the abdominal aorta and iliac arteries is well preserved during the magnetization preparation, artery visualization over a large abdominal field of view is achievable with an inversion delay time that is chosen for optimal background suppression. Healthy volunteer tests demonstrate that the proposed method significantly increases the extent of visible arteries compared with the slab-selective approach, covering renal arteries through iliac arteries over a craniocaudal field of view of 340 mm.

    Full Text Available Athena stands for abbreviation of Abstracting and Thoughtful Evaluation of Neonatal Articles; but it is also personified by the contributor. Like Athena of Greek mythology, she distills wisdom from published literature.Athena is fascinated by the tailbone (coccyx for more than one reason: it is named poetically after the beak of a cuckoo; it is the key Darwinian link between the tail of primates and the tailless Homo sapiens; notwithstanding its tiny size it plays a vital role in anal continence by giving attachment to anal sphincters; and above all it harbors totipotent stem cells giving rise to a peculiar tumor - the Sacrococcygeal Teratoma (SCT. This tumor is peculiar because it is almost always benign to start with and it turns malignant with passage of time. This emphasizes the importance of early surgery and the need to excise coccyx in SCT. Athena believes that studying the natural history of SCT may unravel the secrets of oncogenesis. ...

    1986-04-15

    24 cases of surgically proven ovarian teratomas were analyzed. 1. The most prevalent age group was 3rd decades (57%). 2. The size of most tumors falls into 5-15cm (96%). 3. The site of involvement was more common on left side than right. 4. Well developed teeth or bones were identified in 9 patients on simple abdominal films (39%). 5. Ultrasonographic findings of the tumors were purely cystic in 3 cases (12.5%), mixed in 15 cases (62.5%), and solid in 6 cases (25%). 6. Among mixed typed masses, predominant cystic tumors were 11 cases, and the remained (4 cases) were predominantly solid type. 7. Various ultrasonic findings were seen such as hair-fluid level, linear echoes, scattered echoes, nodular intermixed dense echoes, papillary echogenic mass, and calcifications. 8. Echogenic nodular foci on nonindependent portion were considered to be a helpful diagnostic sign of ovarian teratomas.

    Abstract Teratomas are tumors consisting of tissues derived from more than one germ cell line. Criteria for pulmonary origin are exclusion of a gonadal or other extra-gonadal primary site and origin entirely within the lung. Lung teratomas are rare, and for unknown reasons commonly involve the upper lobe of the left lung. We report a case of intrapulmonary teratoma in a 38-year-old male and review the relevant literature.

    2007-01-01

    Abstract An independent association between acute renal failure(ARF)and intra-abdominal hypertension(IAH)after liver transplantation has not been established previously.The aim of this retrospective study was to understand the role of IAH as an independent risk factor for ARF in the early postoperative period.This study involved 62 subjects who underwent liver transplantation.Intra-abdominal pressure (IAP)was measured in the first three days after surgery by using the urinary bladder technique.An IAP of at least 20 mmHg per day was defined as IAH.Clinical parameters between group IAH and group NO-IAH were compared in terms of the incidence of ARF,blood creatinine levels,blood urea nitrogen (BUN)levels,urine volume per hour and glomerular filtration gradient(GFG).Hemodynamic variations were recorded in the first three postoperative days between group ARF and group NO-ARF.The perioperative suspected risk factors of ARF were determined for statistical evaluation using correlation coefficients and logistic regression analysiIn group IAH.45.8%patients developed ARF as against 7.9in group NO-IAH;GFG was significantly lower at 0-72 h after surgery;and blood creatinine levels,BUN levels,urine volume per hour were significantly different at 24-72 h after surgery compared with group NO-IAH.The patients with ARF were not significantly difierent from those without ARF in terms of central venous pressure,pulmonary artely pressure and mean arterial pressure(MAP) in the first three postoperative days despite a significant increase in heart rate at 24-72h after operation.Postoperative IAH,intraoperative MAP and intraoperative blood transfusion volume of more than 15 U were found to be independent risk factors for ARF.IAH impaired renal function and was an independent risk factor for ARF after liver transplantation.Routine measurement should be taken to monitor IAP every eight hours postoperatively.

    Full Text Available We present a case of mature congenital orbital teratoma managed with lid-sparing exenteration and dermis fat graft. This is a case report on the management of congenital orbital teratoma. A full-term baby was born in Fiji with prolapsed right globe which was surrounded by a nonpulsatile, cystic mass. Clinical and imaging features were consistent with congenital orbital teratoma. Due to limited surgical expertise, the patient was transferred to Adelaide, Australia for further management. The patient underwent a lid-sparing exenteration with frozen section control of the apical margin. A dermis fat graft from the groin was placed beneath the lid skin to provide volume. Histopathology revealed mature tissues from each of the three germ cell layers which confirmed the diagnosis of mature teratoma. We describe the successful use of demis fat graft in socket reconstruction following lid-sparing exenteration for congenital orbital teratoma.

  6. Sacrococcygeal teratoma showed a large cyst on CT scan

    A newborn case with a sacrococcygeal teratoma is reported. A female baby had been noted at birth to have a small hairy pigmented skin lesion over her sacral region. She had shown acute obstructive ileus and bilateral hydronephrosis before long. A benign teratoma with a large cyst was demonstrated on ultra sound echogram and CT scan. The tumor was apparent externally but the predominant mass was intra-pelvic and extended into the retroperitoncal cavity of abdomen. Sacrococcygeal teratoma is uncommon but early diagnosis and surgery is necessary for aquiring good prognosis because it is almost benign. Abdominal CT scan is very worthy and required for diagnosis of the sacrococcygeal teratoma and the differential diagnosis of anterior myelomenigocele and congenital dermal sinus, etc. When a newborn baby is recognized a skin lesion over the sacral region, even though it is mild, CT scan will be necessary for the correct diagnosis, especially in female cases.

    2013-01-01

    Growing teratoma syndrome (GTS) is a rare complication of malignant ovarian germ cell tumors. A 52-year old woman was admitted to our Gynecological Oncology Department with metastatic multiple abdominal masses. Her initial gynecological history presented an immature teratoma of the ovary 3 years previously, and she underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, bilateral pelvic-paraaortic lymphadenectomy and omentectomy. She received three cycles of bleomycin, etoposide and cisplatin (BEP) regimen after surgery. Although the tumor markers were within normal limits, multiple metastatic lesions were detected in the 3rd month of follow-up. The patient was referred to our gynecological oncology department, optimal debulking including resection of the tumoral lesions localized on the liver, diaphragm, peritoneum, sigmoid colon, omentum and retroperitoneum was performed. Histopathology of all samples revealed mature teratoma. This syndrome should be remembered when a tumor is refractory to chemotherapy and growth of the tumor still continues after resection of the initial tumor.

    Ivascu M.; Bembea M.; Jurca Claudia; Moldovan Corina; Buicu F.

    2014-01-01

    Teratomas are rare and complex tumors with components from more than one of the three germ cell layers. Teratomas range from benign, well-differentiated (mature) cystic lesions to those that are solid and malignant (immature). The incidence of all teratomas is estimated at 1:10,000-1:20,000 newborns. Gastric teratomas represent only 1-2% of all teratomas.

  12. Thoracoabdominal teratoma: Rare location

    Cvijanović Radovan

    2011-01-01

    Full Text Available Introduction. Teratomas are tumours derived from pluripotent germ cells. They appear most frequently on ovaries. However, other locations are also possible: testicles, retroperitoneum, stomach, neck, and bottom of the mouth cavity. It is not very common to find teratomas in two different body cavities. Case report. A 51-year-old patient visited her doctor complaining of an intensive pain which suddenly appeared in her low back. The computed tomography scan of the abdomen was performed, which revealed cystic formation, 12.5 x 18 cm in size, with remarkable capsule visualization. It had paraaortic, subdiaphragmatic, retropancreatic and suprarenal left localisation with signs of compression and pancreatic dislocation. The cystic formation had a septated appearance filled with clear fluid in all its parts except at the bottom, where it was dense. The intra-operative finding was left retroperitoneal mass placed above the left kidney, dislocating surrounding structures and their infiltration could not be excluded for sure. A tumour mass passed through the diaphragmatic hiatus and continued in the left thoracic space. The cyst was only drained and the fenestration was performed. Three months later, the second operation was performed-splenectomy, left suprarenaladenectomy, left nephrectomy, aortic deliberalisation, the left diaphragmatic crus was opened and tumour mass was completely removed from the thoracic space. The histological examination showed mature teratoma with morphological characterisations of the skin, so the definite diagnosis was dermoid cyst. Conclusion. The patient presented with thoracoabdominal teratoma. Although without malignant transformation, the teratoma required splenectomy, supraadrenalectomy and nefrectomy due to its position and size.

    1984-01-01

    Chromosome and enzyme markers have been studied in 21 benign ovarian teratomas from 14 patients. Markers heterozygous in the patient were completely homozygous in 52% of the teratomas and completely heterozygous in 19%. The remainder showed a mixture of the two, 10% having homozygous centromeres with some heterozygous enzyme markers and 19% having heterozygous centromeres and some homozygous enzyme markers. These results suggest that benign ovarian teratomas in the present series arise from g...

  18. Contemporary management of the demanding infra-renal neck in abdominal aortic aneurysm repair.

    Mees, B M; Peppelenbosch, A G; De Haan, M W; Jacobs, M J; Schurink, G W

    2015-04-01

    Proximal infrarenal neck anatomy is a crucial factor in determining outcome of abdominal aortic aneurysm (AAA) repair. Unfavorable or demanding infrarenal neck anatomy significantly increases the complexity of both standard endovascular and open repair resulting in increased rates of morbidity and mortality. While technological improvements and expanding institutional experience have resulted in an increased proportion of patients with an AAA with unfavorable infrarenal neck treated by (fenestrated) endovascular techniques, open repair has also remained a valid technique. The purpose of this manuscript was to describe the wide array of endovascular and open techniques in use to treat patients with an AAA with a demanding infrarenal neck and discuss their results and indications. PMID:25592277

  19. Immature thoracic teratoma

    The authors present the case of a 4 month old patient with severe breathing impairment. No other clinical main signs were observed. Ultrasonic, CT and MR studies were performed. The combination of imaging methods permitted to recognize the different tissue of the tumor. The MR showed the topographic diagnostic of the neoplasm, which was supra diaphragmatic and with invasion of the spinal canal simulation a neuroblastoma. The surgical resection by thoracotomy and ulterior histological analysis of the sample confirmed the diagnosis of immature teratoma grade I. The macroscopy revealed a mix cystic/solid structure. The microscopy showed a solid content made of ectoderm, endoderm, mesenchimathic, neurogenic tissue and choroid plexus. (author)

  7. Comparison of diagnostic performance of CT and MRI for abdominal staging of pediatric renal tumors: a report from the Children's Oncology Group

    CT and MRI are both used for abdominal staging of pediatric renal tumors. The diagnostic performance of the two modalities for local and regional staging of renal tumors has not been systematically evaluated. To compare the diagnostic performance of CT and MRI for local staging of pediatric renal tumors. The study population was derived from the AREN03B2 study of the Children's Oncology Group. Baseline abdominal imaging performed with both CT and MRI within 30 days of nephrectomy was available for retrospective review in 82 renal tumor cases. Each case was evaluated for capsular penetration, lymph node metastasis, tumor thrombus, preoperative tumor rupture, and synchronous contralateral lesions. The surgical and pathological findings at central review were the reference standard. The sensitivity of CT and MRI for detecting capsular penetration was 68.6% and 62.9%, respectively (P = 0.73), while specificity was 86.5% and 83.8% (P = 1.0). The sensitivity of CT and MRI for detecting lymph node metastasis was 76.5% and 52.9% (P = 0.22), and specificity was 90.4% and 92.3% (P = 1.0). Synchronous contralateral lesions were identified by CT in 4/9 cases and by MRI in 7/9 cases. CT and MRI have similar diagnostic performance for detection of lymph node metastasis and capsular penetration. MR detected more contralateral synchronous lesions; however these were present in a very small number of cases. Either modality can be used for initial loco-regional staging of pediatric renal tumors. (orig.)

    Choukimath S.M

    2012-01-01

    Full Text Available Background: Benign cystic teratoma is the most common tumor of ovary. Though bilateralism is seen in 10-15% of the cases, bilateral and multiple benign cystic teratomas are rare and very few cases have been reported in the literature. Aim: We present a case of bilateral and multiple benign cystic teratomas with a broad ligament leiomyoma. Case findings: A 38 –year- old female presented with lower abdominal pain of 5 months duration. Ultrasonography of abdomen showed bilateral multiple adnexal cystic masses with multiple hyper-echoic solid components. Laparoscopy was done. There were bilateral tumors, two on right side and three on left side. Posterior surface of the uterus showed a fibroid. Ovarian cystectomy and myomectomy was done under general anesthesia with preservation of both ovaries. Report of bilateral and multiple benign cystic teratomas with broad ligament fibroid was given. Conclusion: When teratomas are multiple and bilateral, recurrence in the form of a dermoid cyst (3% or immature teratoma (2-2.6% in the residual ipsilateral ovary is most frequent. Because of the rarity and increased recurrence rate, we are presenting this case.

    Teratomas are the most common germ cell tumors among pediatric and female patients, which originates from germ cells layers and can be located everywhere in bodies. They are diagnosed by ultrasonography (US), which was characterized by calcification and cystic anechoic view. Our aim is to attract attention to a 21-year-old female patient with complaint of acute abdominal pain diagnosed with teratoma by early radiological im-aging. The female patient admitted to the emergency department with a new onset of abdominal pain at the lower and left sides of the abdomen for a week. The suprapubic and left costovertebral angle tenderness were found in her physical examination. We firstly chose US for imaging. The US of the abdomen showed multiple cystic masses around uterus. Heterogeneous cystic and calcified lesions were detected on the patients computerized tomography scan, and considered as teratoma. A laparotomy was per-formed by gynecologists. At laparotomy, lobulated cystic masses were removed and the left ovary had been detorsioned. She has been discharged after two days of postoperative observation. For patients of young females with abdominal pain such as rare gyneco-logical diseases, teratoma and ovarian torsion, in the emergency department should be considered and early imaging should be performed.

    2005-11-01

    Full Text Available Abstract Background Teratomas are manifested with a great variety of clinical and radiological features, while sometimes they simply represent incidental findings. Case presentation A rare case of benign teratoma of the dermoid cyst type, in an adult 40-year-old female patient, is reported. The patient had presented recurrent pulmonary infections for the previous 2 months, persistent cough, and progressively aggravating dyspnea. A chest X-ray showed total atelectasis of the left lung, and the thoracic CT-scan revealed a huge mass, containing multiple elements of heterogeneous density, probably originating from the mediastinum, occupying the whole left hemithorax. The mass compressed the vital structures of the mediastinum, great vessels and airways, and a chest MRI was performed to accurately detect the anatomical relations. The patient underwent left thoracotomy and the tumor was totally resected. The size of the tumor was extremely large although no invasion to the vessels or to the airway had occurred. Adherence to the adjacent left pulmonary artery and left main bronchus was present, but without erosion or fistulization. The postoperative course was uneventful, while the histological examination confirmed a teratoma. Conclusion A teratoma is a non-homogeneous pathological entity, clinically, radiologically or histologically. It is predominantly diagnosed between the second and fourth decade and the incidence is equal for both sexes. Symptoms are absent in one half of the patients. The case reported is noteworthy as the tumor appeared with total atelectasis of the left lung, and symptoms started 2 months prior to diagnosis. Total removal of the tumor is adequate treatment for this type of teratoma and the prognosis is excellent.

    Full Text Available The most frequent ovarian germ cell tumours are mature cystic teratoma (MCTs , comprising 10 - 25% of all ovarian neoplasms. Malignant transformation in a mature cystic teratoma of the ovary is a rare complication. Squamous cell carcinoma is the most common transformation followed by adenocarcinoma. CASE REPORT: A 36 year old female presented with abdominal pain , fullness , difficulty in periods since 6 months. According to examination and CECT abdomen 13.5x13cm mass is found on the left adnexal region. Patient underwent oophrectomy. According to histopathological diagnosis , adenosquamous carcinoma arising in mature cystic teratoma is diagnosed as a reason for the mass in the left adnexa of the patient.

  1. Bipartite Anterior Extraperitoneal Teratoma: Evidence for the Embryological Origins of Teratomas?

    Keene, D. J. B.; Craigie, R. J.; Shabani, A.; Batra, G.; Hennayake, S.

    2011-01-01

    Teratomas are thought to arise from totipotent primordial germ cells (PGCs) Dehner (1983) which may miss their target destination Moore and Persaud (1984). Teratomas can occur anywhere from the brain to the coccygeal area but are usually in the midline close to the embryological position of the gonadal ridges Bale (1984), Nguyen and Laberge (2000). We report a case of a bipartite anterior extraperitoneal teratoma. This is an unusual position for a teratoma, but one which may support the “mis...

    2011-01-01

    Teratomas are tumors composed of tissues derived from more than one germ cell line. Pulmonary teratomas are rare and commonly involve the upper lobe of the left lung. Criteria for pulmonary origin are the exclusion of a gonadal or other extragonadal primary site and origin entirely within the lung. We report a case of a giant pulmonary teratoma in a 2-year-old male child and review the relevant literature.

    2003-04-01

    Background: Neonatal nasopharyngeal teratomas are extremely rare and there are few reports describing both CT and MRI features of these lesions. Objective: To describe the CT and MRI appearances of neonatal nasopharyngeal teratoma. Materials and methods: Three neonates with nasopharyngeal teratomas and severe respiratory distress were reviewed. Results: The nasopharyngeal mass resulted in severe respiratory compromise requiring urgent intervention. Characteristic mandibular and pterygoid plate abnormalities demonstrated by CT and MRI are described. Conclusions: Prenatal MRI enables the diagnosis, delineates tumour extent and allows planned delivery. CT and MRI play a key role in differentiating neonatal nasopharyngeal teratomas from other causes of a neonatal neck mass, thus optimising management. (orig.)

    2012-07-01

    Full Text Available Germ cell tumors are malignant (cancerous or nonmalignant (benign, noncancerous tumors that are comprised mostly of germ cells, the cells that develop in the embryo and become the cells that make up the reproductive system in male and female. Most ovarian tumors are of germ cell origin. A 5-year-old female child was taken to the Paediatrics department at Tawau General Hospital (TGH, Sabah, Malaysia on 10.4.2005 with gradual distension of abdomen which had been noticed by parents for the last 2 months. As bedside ultrasonography (USG showed mixed echogenic mass in the lower abdomen, CT scan of abdomen was requested for further delineation. CT scan of abdomen done on 18.4.2005 showed a very large (about 12 × 9 cm mixed density mass with homogenously enhancing well defined borders in the abdomen extending from the pelvic cavity to the upper abdomen causing significant pressure effect downwards towards urinary bladder and contrast material filled guts outwards and backwards mostly occupying the anterior part of abdominal cavity. The tumor was removed surgically and diagnosed as ovarian teratoma histopathologically.

  5. Cystic struma ovarii: a rare ovarian teratoma

    Struma ovarii is a unique variant of the monodermal teratomas of the ovary, which is entirely composed of thyroid tissue. It is a rare tumor which comprises 1-4% of all benign ovarian tumors. The age of presentation ranges between 6 to 74 years. It is a benign tumor and is usually unilateral. Clinical symptoms such as pelvic mass, abdominal pain and ascities occur in one third of patients, whereas rarely patients may present with pseudo-meig syndrome. Ultrasonography and computed tomography show a solid cystic mass. Histologically benign struma ovarii contain thyroid follicles of variable sizes filled with colloid. A 53 years old female presented with one month history of lower abdominal pain. The clinical and radiological findings suggested a left ovarian mass measuring 7 x 5 x 3 cm. An exploratory laparotomy was performed and the left ovarian mass was resected. The specimen was sent to AFIP for anatomical diagnosis. On gross examination, the specimen consisted of left ovary measuring 14 x 12 x 6.5 cm and weighing 527 grams. External surface of the ovary showed many multinodular areas with few cystic areas. Largest of the cyst measured 8 x 7 x 4 cm. On opening all the cysts contained yellowish watery fluid. Maximum thickness of the largest cyst wall was 0.5 cm. The solid area in the ovary measured 5 x 4 x 3 cm. On serial slicing the solid areas had whitish variegated appearance and areas of gritty hard consistency. No fallopian tube was found. Representative sections from different areas of the specimen were prepared. Histologically, the sections revealed effacement of the normal ovarian architecture by mature thyroid follicles containing colloid (Fig. 2). Some areas showed degenerated thyroid tissue with hyalinization and areas of calcification. More than 50% of the material examined contained thyroid tissue. No evidence of atypia was seen in the material examined. (author)

    Full Text Available Mature cystic teratoma compromise 20-30% of all ovarian tumours. They are mostly seen in patients between 20 and 40 years of age and are mostly asymptomatic. Malignancy incidence is high in postmenopausal group. Here, we report a case of mature cystic teratoma presenting unusually in a 65 year old postmenopausal woman with pain abdomen. A 65 year old postmenopausal woman presented with lower abdominal pain of 15 days duration. Upon examination, a mass of size 7 and times;8 cm felt on bimanual examination. CT showed the same cyst that has a focal enhancing mural nodule with fat density in it. Total abdominal hysterectomy with bilateral salpingo oopherectomy done. Histopathological examination confirmed mature cystic teratoma. Although mature cystic teratoma is rare after 40 years age, especially in postmenopausal women and are usually malignant in that age group, it can have an unusual age presentation at 65 years with benign nature as in our case.

    2007-06-01

    Full Text Available Blunt rupture of the renal pelvis is a exceedingly rare injury. Hematuria is absent in one-third of cases. Such injuries are usually caused by desacceleration forces. Despite improved imaging techniques, diagnosis of this injuries is frequently delayed. Diagnosis is suggested by the presence of massive medial extravasation of contrast material at excretory urography or computed tomography. Surgical treatment consists in pyeloplasty or pyeloraphy with stent placement (double J or nephrostomy.

    To evaluate the sonographic findings of fetal congenital intracranial teratoma. From 1994 to 2002, of the 11 fetuses which had been diagnosed with fetal intracranial tumors after second level fetal ultrasonography, the six that were confirmed after autopsy as congenital intracranial teratomas were included in our study. The sonographic findings, including size, homogeneity, echogenicity compared with surrounding normal brain tissues, cystic components, and tumor related calcification, were retrospectively evaluated. The incidence of fetal congenital intracranial teratoma out of all fetal intracranial tumors was 54.5% (6 of 11 cases) during the 8-year period. The mean mass size was 7.4 cm (3.0-15.0 cm). Two thirds of (4/6) of the teratoma cases showed high echogenicity compared with normal brain tissues, and two thirds (4/6) showed heterogeneous echogenicity. Four teratoma cases (67%) showed cysts in the mass with a mean size of 1.9cm. One third (2/6) showed calcifications within the tumor. Out of the six cases, two had oropharyngeal teratoma with extension into the intracranial portion (so called epignathus) and showed homogenous mass without any cysts or calcifications. The typical sonographic appearance of intracranial teratoma was a heterogeneous, hyperechoic mass with cysts. In the epignathus cases, the sonographic appearances differed somewhat from the others. An understanding of the sonographic findings of fetal intracranial teratoma will help in the timely counseling of the parents and in obstetric decision making

    Full Text Available Abstract Background Teratoma is a rare developmental neoplasm that arises from totipotential tumor stem cells. Head and neck teratomas constitute about 10% of all cases. Only two cases of mature teratoma of the nasal septum have previously been documented in the world literature. Case presentation We present a case of histologically confirmed mature teratoma arising from the nasal septum in an eighteen month old Nigerian female who presented with a history of noisy breathing associated with recurrent rhinorrhea since birth. Physical examination revealed obstruction of the right nasal cavity by a pale fleshy mass. She underwent a total surgical excision and to date, after thirty one months follow-up, she is free from recurrence. Conclusion The prognosis for benign teratoma of the nasal septum is good following total surgical excision.

    2006-04-01

    Full Text Available This study considers a unilateral renal agenesia associated with agenesia of the epididymis body and tail and the vas deferens and non-palpable left testicle in a 20-month-year-old patient. During laparoscopic procedure, the testicle was positioned at approximately 5 cm above the inguinal ring. The size was appropriate for the age and the head of the epididymis was situated in its normal position. The decision was made to perform the first step of the Fowler-Stephens’ surgery and the patient presented a good evolution. The association of male duct system agenesia with unilateral renal agenesia in a patient with cryptorchidism diagnosed by laparoscopy is an extremely rare event, however generally in these cases the testicle is of normal size, presents unaltered hormonal function, and must be preserved.

  15. Beta 1 integrin is essential for teratoma growth and angiogenesis

    Bloch, W; Forsberg, E; Lentini, S;

    1997-01-01

    Teratomas are benign tumors that form after ectopic injection of embryonic stem (ES) cells into mice and contain derivatives of all primitive germ layers. To study the role of beta 1 integrin during teratoma formation, we compared teratomas induced by normal and beta1-null ES cells. Injection of...... normal ES cells gave rise to large teratomas. In contrast, beta 1-null ES cells either did not grow or formed small teratomas with an average weight of <5% of that of normal teratomas. Histological analysis of beta 1-null teratomas revealed the presence of various differentiated cells, however, a much...... lower number of host-derived stromal cells than in normal teratomas. Fibronectin, collagen I, and nidogen were expressed but, in contrast to normal teratomas, diffusely deposited in beta1-null teratomas. Basement membranes were present but with irregular shape and detached from the cell surface. Normal...

    Ultrasonography is a very useful diagnostic modality for the evaluation of clinically suspicious abdominal masses in infants and children, especially in assessing their existence, size, location, origin and internal consistency. Authors analyzed and present ultrasonographic findings of 92 pathologically and/or clinically proven pediatric abdominal masses that were studied and treated in Chonnam University Hospital during recent 4 years. The results were as follows: 1. The most common originating site was kidney (26 cases: 28.3%), followed by gastrointestinal tract (21 cases: 22.8%), genital organ (17 cases: 18.5%), non-renal retroperitoneum (13 cases: 18.5%), hepatobiliary tract (12 cases: 13.0%), and anterior abdominal wall (3 cases: 3.3%) in order to frequency. 2. The most common mass was hydronephrosis (18 cases: 19.6%). Neuroblastoma (7 cases: 7.6%), hepatoblatoma, ovarian teratoma, periappendiceal abscess and abdominal tuberculosis (6 cases: 6.5%, respectively), Wilms tumor (5 cases: 5.4%) were next in order of frequency. 3. The sex distribution is rather similar, that is, male 42 (45.7%) and female 50 (54.3%), but characteristically choledochal cyst (2 cases) and genital mass (17 cases) were found only in females. Considering age distribution, 78 cases (84.8%) were found within the range of one to 15 years of age. The rest, 14 cases (15.2%), were under the age of one year. 4. With ultrasonography, the diagnosis of hydronephrosis could be made easily in every case and we could evaluate its severity and level of obstruction with high accuracy. 5. All Wilms tumor were large, round or oval, sharply marinated and relatively homogeneous solid masses. 6. All neuroblastomas were irregular shaped, poorly defined, heterogeneous solid masses. Tumor calcification and extension across the midline were noted in 6 cases (85.7%) and 5 cases (71.4%), respectively. 7. All periappendiceal abscess had irregular thickened wall and posterior acoustic enhancement; 4 cases (66

    Mature cystic teratomas are benign neoplasms of germ cell tumors that occur most frequently in gonadal sites. The tumors usually contain 2 or 3 well-differentiated elements of endodermal, ectodermal, and mesodermal origin. Although relatively uncommon, teratomas can be composed of mature tissue originating from only 1 germ cell layer. This is known as a monodermal teratoma. Extragonadal teratomas, especially mesenteric teratomas, are extremely rare. Currently, only 21 cases of mesenteric tera...

    Majid Samsami

    2011-06-01

    Full Text Available Background:Congenital germ cell tumors are uncommon. The most common site of teratoma is in the sacrococcygeal region. Teratoma arising from the head and neck comprises less than 10% of reported cases and of these, nasopharyngeal lesions are rare. Teratomas are generally benign, and have a well recognized clinical and histopathological entity. We present a case of nasopharyngeal teratoma (NPT associated with a wide cleft palate. Case Presentation:A 20 day old female neonate with a teratoma of the nasopharyngeal area, and wide cleft palate was referred to our center. The protruded mass which measured 6×4×3cm, was of soft consistency, blocked the airway, and prevented oral feeding. Preoperative evaluation and imaging was performed and mass was excised 2 days after admission. Pathology revealed a well-differentiated mature solid teratoma (hairy polyp. The patient had no complication in the post-operative period. Cleft palate was surgically repaired when 2 years old. She is now a six year old girl with normal development. Conclusion:Congenital nasopharyngeal teratomas are usually benign. Surgery is the treatment of choice, and should be undertaken on an urgent basis, especially in a patient who presents with signs and symptoms of airway obstruction.

    Full Text Available Teratoma is a tumor that derivatives from all three primitive germ layers and spinal intramedullary teratomas are very rare lesions. The primary treatment modality for these tumors is surgical resection, and total resection should be the aim. However, subtotal resection is a valid alternative to prevent traumatizing adjacent functional neural tissue. In this report, we presented a case of a 12-year-old male patient with spinal teratoma of the conus medullaris. We describe the presentation, evaluation, and treatment of this rare disease.

    Full Text Available Of all primary retroperitoneal teratomas, less than four percent occur in children and 90% are benign. Here we report a case of malignant retroperitoneal teratoma (dermoid in a 15 year old girl who presented to our hospital - Acharya Vinoba Bhave Rural Hospital (AVBRH. She presented with a tender, large, irregular mass with variegated consistency in the entire left side of abdomen crossing midline. Ultrasound of abdomen suggested a complex intra-abdominal mass with septations and lobulations. It was not feasible to use other imaging modalities for evaluation due to poor socio-economic status and illiteracy. Patient underwent exploratory laparotomy with tumor resection along with left kidney and part of the descending colon which was densely adhered to tumor. Histopathological examination of tumor was suggestive of immature teratoma. Post operative recovery was uneventful and patient was discharged from the institution. Tissue adherence which can be observed in both benign and malignant form of teratomas, requires extended surgery for removal of adhered organ for the completeness of surgery and good prognosis.

    We report an extremely rare case of gas-filled abdomi?nal mass caused by an ovarian teratoma fistulating to the sigmoid colon. The patient was an 85-year-old female, who presented with severe abdominal disten?sion. Urgent computed tomography scan showed a huge abdominal mass with air fluid level and fecal matter inside. Communication between the mass and the sigmoid colon was suspected. She underwent emergency laparotomy. The mass was resected with the involved segment of colon. Pathology confirmed squamous cell carcinoma arising from mature cystic teratoma of the ovary.

  8. Diagnostic imaging of infantile abdominal cystic disease

    Thirty-seven patients with infantile abdominal cystic disorders were studied by ultrasound (US), computed tomography (CT), or magnetic resonance imaging (MRI). US studies are simple to conduct, and commonly show an echo-free mass, but tend to yield hyperechoic images when fat and blood are present in the cystic fluid. CT studies, which distinctly demonstrate water, fat, soft tissue density and calcification, are very helpful in the diagnosis of cystic tumor, especially cystic teratoma. MR imaging, which is capable of distinguishing the nature of the cystic fluid (e.g., serous, chylous, bloody, fatty, etc.), is useful in the diagnosis of lymphangioma, teratoma, and torsion of ovarian cystic tumor. Based on the results of the present study, US may be considered to be the modality of first choice in the examination of infantile abdominal cystic disorders, and MRI and/or CT should be employed additionally as necessary in that order.

    1984-09-15

    Teratomas, usually arising in the anterior mediastinum, are very uncommon in the posterior mediastinum. Embryologic development of anterior mediastinal teratoma is thought to be from thymic anlage which descends from the third bronchial cleft and pouch, while that of posterior mediastinal teratoma is thought to be from the remnant of notochord. CT findings of posterior mediastinal teratomas are not different from teratomas elsewhere, containing fat, calcification, soft tissue and thick walled cyst. Ultrasonographic findings are mixed echogenic mass containing cystic portion, highly reflective solid portion and area of acoustic shadowing. Authors recently experienced 2 cases of surgically proven posterior mediastinal teratoma and report with review of literature.

    We reviewed the magnetic resonance imaging(MRI) of intracranial teratoma to defect the characteristic findings. Five patients with intercranial teratoma were evaluated with MRI from January 1988 to December 1990. Four male and one female patients with age ranging from 6 to 14 years were surgically confirmed. MRI was done with 2.0 T superconducting system(Spectro 20000, Goldstar, Seoul) and gadolinium enhancement was done in 4 patients. We retrospectively reviewed the clinical, operative, pathologic, and radiologic findings. Intracranial teratomas showed fatty component, calcification and cystic component filled with sebum or serous fluid. Peripheral rim enhancement was seen in three and irregular enhancement in two cases. There were hydrocephalus in all pineal teratoma, but neither surrounding edema nor surrounding tissue invasion was seen. Low signal intensity rim was noted the solid component of all tumors and they were not enhanced. MRI showed multicomponent of intracranial teratoma including the solid and cystic component, and low signal rim which might be the characteristic finding of the intracranial teratoma.

  12. Mature Cystic Teratoma of the Fallopian Tube in a Postmenopausal Woman: A Case Report and Review of the Literature

    Mustafa Erkan Sari

    2015-01-01

    Full Text Available Background. Mature cystic teratomas of the fallopian tube are extremely rare and only 54 cases have been reported in the literature. In this paper, we report a mature cystic teratoma of the fallopian tube in a postmenopausal woman and we report the review of literature of tubal cystic teratomas. Case. A 62-year-old, gravida 4 postmenopausal woman presented with pain in the right lower abdominal region for a long time. An 88 × 72 × 95 mm heterogeneous mass which contained calcifications and lipoid components was detected in the right adnexal region by transvaginal ultrasonogram (TV-USG. Serum tumour markers, namely, CA125, CA15-3, and CA19-9, were within normal range. A laparotomy revealed a 9 × 10 cm cystic mass within the fimbrial region in the right fallopian tube, and right salpingoopherectomy was performed consequently. Microscopic examination revealed squamous epithelium with sebaceous glands and hair follicles, and pseudostratified ciliated respiratory epithelium with cartilage and mucous glands. Because the frozen section resulted in a benign dermoid cyst, no further operative procedure was performed. The postoperative follow-up was uneventful and the patient was discharged on the second postoperative day. Conclusion. In cases of undetermined pelvic or abdominal masses, a teratoma of the fallopian tube should be considered.

    2014-08-01

    Full Text Available : Collision tumors involving ovaries are extremely rare. Here, we report this rare entity in a 23 years old primigravida presented with 12 weeks pregnancy and abdominal pain. Ultrasonography showed large right adnexal mass measuring 20 x 13 cm. having solid area with multiple cysts and bulky left ovary of 6 x 4.6 cm. Normal ovarian tissue was preserved after bilateral ovarian cystectomy. Grossly, right ovarian tissue revealed multiloculation and mucin filled cysts. Left ovarian cyst was filled with hairy pultaceous material. Histological diagnosis of collision tumor of right ovary comprising hemorrhagic mucinous cystadenoma and benign cystic teratoma along with dermoid cyst in left ovary was rendered. The pathogenesis of association of mature cystic teratoma with a mucinous cystadenoma has yet to be answered and the choice of management necessitates a weighing of risks based on characterization of the adnexal mass and gestational age.

    2009-06-01

    Full Text Available Abstract Background Malignant transformation of mature cystic teratoma is a rare complication. While any of the constituent tissues of a teratoma has the potential to undergo malignant transformation, squamous cell carcinoma is the most commonly associated malignancy. Renal carcinoid tumors are rare and frequently associated with horseshoe kidney and renal teratoma. Renal teratoma rarely presents together with carcinoid tumor or adenocarcinoma. To the best of our knowledge, there has never been a report of renal teratoma coexisting with both carcinoid tumor and adenocarcinoma. Methods Here, we present a unique and first case of synchronous primary carcinoid tumor and moderately differentiated adenocarcinoma arising within mature cystic teratoma of horseshoe kidney in a 50-year-old female. Lumbar spine X-ray, done for her complaint of progressive chronic low back pain, accidentally found a large calcification overlying the lower pole of the right kidney. Further radiologic studies revealed horseshoe kidney and a large multiseptated cystic lesion immediately anterior to the right renal pelvis with central calcification and peripheral enhancement. She underwent right partial nephrectomy. Results Macroscopically, the encapsulated complex solid and multiloculated cystic tumor with large calcification, focal thickened walls and filled with yellow-tan gelatinous material. Microscopically, the tumor showed coexistent mature cystic teratoma, moderately differentiated adenocarcinoma and carcinoid tumor. Immunohistochemically, alpha-methylacyl-coenzyme A-racemase, calretinin, CD10 and thyroid transcription factor-1 were negative in all the three components of the tumor. The teratomatous cysts lined by ciliated epithelium showed strong staining for cytokeratin 7 and pancytokeratin, and those lined by colonic-like epithelium showed strong staining for CDX2, cytokeratin 20 and pancytokeratin, but both were negative for calretinin. Additionally, the

    Teratomas are germ cell tumors, manifested with a great variety of clinical features; the most common extragonadal site is the anterior mediastinum. In this case, we report the patient with a large mature mediastinal teratoma with several components of ectodermal and endothermal epithelium. A 24-year-old female patient presented with history of persistent chest pain and progressively aggravating dyspnea for the previous 3 months. A chest X-ray showed a large opacity of the entire left hemithorax. Transcutaneous needle aspiration revealed a purulent fluid. The tube thoracostomy was introduced and the effusion was evacuated. Some weeks later, patient was seen in emergency for persistent cough and lateral chest pain. CT scan revealed a mass of the left hemithorax. The mass showed heterogeneous density, without compressing mediastinum great vessels and left hilar structures. Lipase value was elevated in needle aspiration. The patient underwent a total resection of the mediastinum mass via a left posterolateral thoracotomy. Microscopy revealed a mature teratoma with cystic structures. The patient subsequently made a full recovery. This case provide benign mediastinal teratoma with total atelectasis of left lung and elevated lipase value in needle transcutaneous aspiration; this event is explained by pancreatic component in the cystic tumor. Total removal of the tumor is adequate treatment for this type of teratoma and the prognosis is excellent. PMID:27144046

    Teratomas are rarely seen in adults, and presacral region is an area where they rarely settle in. Similarly, only about 1% of teratomas show malignant transformation. Malignant transformation is often associated with the area where teratoma settles in. Malignant transformation of mediastinal teratomas is more frequent than the ones located in retroperitoneal area and gonad. They most commonly show rhabdomyosarcoma, primitive neuroectodermal tumor, enteric adenocarcinoma, and leukemia transfor...

    We describe here a female patient who presented with a breast mass and giant abdominal mass.Fine needle aspiration cytology of the breast mass and histological examination after modified radical mastectomy confirmed metaplastic carcinoma of the breast.The epithelial components were formed by infiltrating ductal carcinoma with poor differentiation,and the sarcomatous components were formed by fibrosarcoma and osteosarcoma.Histological examination of the abdominal mass confirmed ovarian teratoma.The patient underwent modified radical mastectomy of the right breast and laparoscopic excision of the abdominal mass in the lower right quadrant.Having underwent six courses of chemotherapy,the patient is now in her tenth month after surgery and under follow-up,and she has no relapsed disease.These two diseases have never seen in one patient before.The case we report here provides some new data for research and clinical experience and it may also provide a new insight into the relationship between metaplastic breast carcinoma and ovarian teratoma.

  6. Abdominal Dual Energy Imaging

    Sommer, F. Graham; Brody, William R.; Cassel, Douglas M.; Macovski, Albert

    1981-11-01

    Dual energy scanned projection radiography of the abdomen has been performed using an experimental line-scanned radiographic system. Digital images simultaneously obtained at 85 and 135 kVp are combined, using photoelectric/Compton decomposition algorithms to create images from which selected materials are cancelled. Soft tissue cancellation images have proved most useful in various abdominal imaging applications, largely due to the elimination of obscuring high-contrast bowel gas shadows. These techniques have been successfully applied to intravenous pyelography, oral cholecystography, intravenous abdominal arteriog-raphy and the imaging of renal calculi.

  7. Case report: Varicosity of the communicating vein between the left renal vein and the left ascending lumbar vein mimicking a renal artery aneurysm: Report of an unusual site of varicose veins and a novel hypothesis to explain its association with abdominal pain

    Sandeep G Jakhere

    2011-01-01

    Full Text Available A communicating vein between the left renal vein and the left ascending lumbar vein has only rarely been reported in the imaging literature. There are very few reports of varicosity of this communicating vein. Nonetheless, awareness about this communicating vein is of utmost importance for surgeons performing aortoiliac surgeries and nephrectomies as it may pose technical difficulties during surgery or cause life-threatening retroperitoneal hemorrhage. Varicosity of this venous channel may be mistaken for paraaortic lymphadenopathy, adrenal pseudo-mass, or renal artery aneurysm. We report a case of a patient with varicosity of this communicating vein, which mimicked a left renal artery aneurysm. A novel hypothesis is also proposed to explain the relationship with abdominal pain.

    We report a case of an abdominal mass in a newborn girl containing a fetus in fetu and two teratomas. Obstetrical sonography revealed the abnormality at 28 weeks of gestation. Post-natal US examination suggested the diagnosis of a fetus in fetu upon the finding of a vertebral column and fetal skeletal bones. US also showed two other rounded masses connected to the main lesion by vascular bundles. Preoperative MRI examination supplied further information regarding tissue composition and vascularisation of the mass lesion. The diagnosis was confirmed by pathological examination. Aetiological factors and radiological diagnosis of this rare tumour are reviewed and discussed. (orig.). With 4 figs.

    We report the case of a 19-year-old woman experiencing lower abdominal distension and pain. Laboratory tests indicated elevated serum levels of Alpha-Fetoprotein (AFP) and human Chorionic Gonadotropin (hCG). A large mass was detected in the abdomen by physical examination and by transvaginal ultrasonography. Exploratory laparotomy was performed, and a smooth-surfaced, spherical, solid tumor was found on the left ovary, measuring 11.5 x 9.9 x 6.9 cm. Histological evaluation revealed that the tumor consisted of a combination of immature teratoma, Yolk Sac Tumor, and embryonal carcinoma; this is a very rare combination in mixed germ cell tumors.

  13. Intraluminal esophageal teratoma in a neonate

    Mark L. Ryan

    2015-10-01

    Full Text Available Teratomas are germ cell tumors containing one or more of the three embryonic layers (endoderm, mesoderm, and ectoderm. In neonates, the sacrococcygeal region is the most frequent site of origin, followed by the gonads and mediastinum. While most mediastinal teratomas are anterior, approximately 3–8% are found within the posterior mediastinum. Here we report the case of an infant who presented in the second week of life with frequent emesis followed by choking, dyspnea, and perioral cyanosis. An esophagram demonstrated a large pedunculated polypoid mass within the lumen of the esophagus. CT confirmed a 5 × 1.8 cm intraluminal mass with a stalk originating from the posterior wall of the esophagus at C6. Endoscopic retrieval was not possible due to its large size. The mass was operatively resected via a right-sided, 2 cm transverse cervical incision. An oblique esophagotomy was made; the polypoid mass was grasped and eviscerated using serial traction sutures. The mass was excised along with a rim of normal esophageal mucosa. Final pathology demonstrated a mature and solitary esophageal teratoma. To our knowledge, this is the first reported case of an intraluminal cervical esophageal teratoma, and the youngest patient in which a pedunculated esophageal polyp has been described.

    2014-01-01

    Full Text Available Anti-NMDAR (N-methyl-D-aspartate receptor encephalitis is an immune-mediated encephalitis. It has been predominantly described in young women and is commonly associated with an ovarian teratoma. We report a case of anti-NMDAR encephalitis associated with a 7 mm ovarian teratoma that was completely resected by laparoscopic surgery. An 18-year-old woman suddenly presented with personality changes requiring her admission to the department of neurology. After that, she also showed involuntary movements, disturbance of consciousness, and central hypoventilation. As an abdominal image revealed the possibility of a right ovarian teratoma of 5×7 mm, a laparoscopic operation was performed. The macroscopic appearance of the right ovary did not show any abnormalities; nevertheless, we performed a partial resection of the right ovary, with reference to the image diagnosis, in order to spare the ovarian reserve. The 22×22 mm partially resected ovary contained an intact 5×7 mm cystic tumor. The pathological diagnosis was mature cystic teratoma with components of brain tissue. An anti-NMDAR-antibody test proved positive in both serum and cerebrospinal fluid 1 month after the surgery. From these results, she was diagnosed with anti-NMDAR encephalitis. By the administration of cyclophosphamide in addition to the operation, she recovered drastically without any of the symptoms shown before.

    2016-05-01

    Full Text Available Spontaneous ovarian teratoma was found in a seven-week-old female Chunky broiler chicken that was slaughtered for food. On post-mortem inspection, a spherical tumor mass attaching to a juvenile ovary was found in the abdominal cavity. Histopathologically, the tumor was comprised of immature mesenchymal stroma and a variety of mature tissue elements of mesodermal and ectodermal origin. In addition, there were multiple indistinguishable tissue elements, which showed no malignant cytological features but were unidentifiable as to corresponding embryological layer of origin. These heterogeneous teratoma tissues consisted of a variety of glandular, cystic, duct-like, and tubular structures, some of which exhibited a lining by a mixture of both keratinizing/non-keratinizing stratified squamous epithelial cells and cuboidal/columnar epithelial cells. The ovarian tetatoma was considered a benign and congenital one. The highly diverse differentiation of the teratoma might have manifested a morphological aspect of intrinsic character of the pluripotential germ cells during tumorigenesis.

  2. The value of MRI in diagnosis of ovarian cystic teratoma

    Objective: To study the MRI manifestations and diagnostic values in ovarian cystic teratoma. Methods: MRI appearances of 52 cases of ovarian cystic teratoma confirmed by surgery and pathology were analyzed retrospectively. Results: All of 52 cases were confirmed as mature cystic teratoma by pathology. Of the 52 cases, 43 were unilateral, 9 cases bilateral. And 61 lesions were totally found. The diameter of lesions was 12.8 cm-2.7 cm. The appearance of MRI was mainly cystic. The cystic area of the lesion showed low signal intensity on T1WI and high signal intensity on T2WI. The wall of the cyst was smooth and enhanced after contrast medium administration. MRI revealed that 52 cases were mixed intensity and containing variety of fat signal intensity area. The accuracy of MRI diagnosis in ovarian cystic teratoma was 100%. Conclusion: Ovarian teratoma has characteristic appearances in MRI. Pelvic MRI examination for ovarian teratoma can make exact diagnosis. (authors)

    Full Text Available Intrapericardial teratomas are rare causes of mediastinal masses in children. Pericardial teratoma is a potentially curable lesion that may become life threatening when it induces mediastinal compression and fetal hydrops. Majority of the reported cases have been diagnosed prenatally. We report a case of an infant with intrapericardial immature teratoma, which was detected in a newborn infant presenting with respiratory distress. The tumor was excised completely, and histopathological examination of the resected tumor was suggestive of immature teratoma. The patient was asymptomatic three months postoperatively.

  9. Mature cystic teratoma with malignant transformation of teratomatous urothelial cells: Rare case presentation

    Senjuti Dasgupta

    2015-01-01

    Full Text Available The occurrence of malignancies in somatic elements of mature cystic teratoma of ovary is rare. The malignancies that may be encountered in dermoid cyst include squamous cell carcinoma, adenocarcinoma, adenosquamous carcinoma, melanoma, sarcoma, carcinoid, and germ cell neoplasms. The development of transitional cell carcinoma (TCC in dermoid cyst is extremely rare with only four such cases having been reported in literature so far. Here we report the fifth case of such an occurrence in a 50-year-old postmenopausal multiparous female patient. She presented with pain and gradual swelling of abdomen for 1 month. Abdominal computed tomography revealed a solid space occupying lesion with few cystic components at right pelvis, raising the possibility of an ovarian neoplasm. The level of CA-125 was slightly raised (56∙45 U/ml. Total abdominal hysterectomy and bilateral salpingo-oopherectomy was performed. Microscopic examination showed cyst wall lined by stratified squamous epithelium. Beneath the cyst wall, a tumor mass was present, histological features of which resembled that of high-grade TCC (stage pT1aNXMX. On immunohistochemical analysis, the tumor was found to be positive for CK7 and CK20 and negative for WT-1. These results were consistent with a diagnosis of TCC arising in urothelium of mature cystic teratoma. Reporting of such extremely rare cases is important for the assessment of prognostic factors and treatment protocols.

    2016-01-01

    Abstract Germ cell tumors (GCTs) represent a well-recognized group of heterogeneous neoplasms with diverse clinical, histopathological, diagnostic, and prognostic characteristics. We present a rare case of a locally aggressive, chemotherapy-resistant immature mediastinal teratoma with a peculiar histological finding of a multilineage somatic-type malignant degeneration. A 21-year-old male patient presented with a 3-week history of persistent, blood-tinged productive cough and shortness of breath. A contrast-enhanced computed tomography (CT) scan of the chest showed a heterogeneous mass occupying the right hemithorax and abutting on adjacent structures. CT-guided biopsy was consistent with immature teratoma. Combination chemotherapy with bleomycin, etoposide, and cisplatin was initiated, albeit without success; the mass showed interval progression in size, and surgical resection through clamshell incision was performed. Histological assessment of the resected mass confirmed the diagnosis of immature teratoma and revealed an extensive multilineage malignant differentiation into sarcomatous, carcinomatous, and melanomatous components. The patient underwent an uneventful recovery but presented 2 months later with extensive liver and bone melanomatous metastases. In this report, relevant findings from the literature are also highlighted. Despite being exceptionally rare, such tumors carry poor prognosis. Understanding the clinicopathological characteristics and biological behavior of such tumors may provide an insight into interventions tailored to improve the otherwise dismal disease outlook.

  15. Abdominal Assessment.

    Fritz, Deborah; Weilitz, Pamela Becker

    2016-03-01

    Abdominal pain is one of the most common complaints by patients, and assessment of abdominal pain and associated symptoms can be challenging for home healthcare providers. Reasons for abdominal pain are related to inflammation, organ distention, and ischemia. The history and physical examination are important to narrow the source of acute or chronic problems, identify immediate interventions, and when necessary, facilitate emergency department care.

  16. The growing teratoma syndrome secondary to immature teratoma of the ovary

    The growing teratoma syndrome (GTS) secondary to a testicular nonseminomatous germ cell tumor has been well described since the first case was reported in 1982. In addition, radiological findings of male GTS have also reported in several studies; however, its occurrence secondary to an ovarian germ cell tumor is extremely rare. We experienced a 5-year-old girl who had GTS secondary to immature teratoma of the right ovary. In this article we present radiological findings of female GTS with clinical and pathological correlation. (orig.)

    Full Text Available Abstract Background Primary carcinoid tumor arising within mature teratoma of the kidney is extremely rare, and their clinicopathologic features are not well described. Our objective was to further define the clinical features and pathologic spectra of primary carcinoid tumor arising within mature teratoma of the kidney. Methods Six previously reported case reports were identified using MEDLINE and a subsequent bibliographic search of all pertinent reports and reviews was performed. We also searched the electronic medical archival records of our institution and identified one additional unreported case. Data were extracted on the demographics, predisposing factors, clinical presentation, radiographic features, gross pathology, microscopic pathology, immunophenotype, therapy, and outcome of each of these seven cases. Results Primary carcinoid tumor arising within mature teratoma of the kidney was found at a mean age of 41.4 years. Of the 7 cases, 3 were female and 4 were male. Two of the 7 cases (28.6% were associated with horseshoe kidney. It typically presented with abdominal pain without carcinoid syndrome. It typical radiologic appearance was well circumscribed partly calcified Bosniak II-III lesion. Histologically, the carcinoid tumor showed monotonous small round cells arranged in classic anastomosing cords/ribbons intermixed with solid nests. Surgery was curative, no additional treatment was required, no local recurrences occurred, and no metastases occurred in all 7 cases. The 3 cases with available outcome data were alive at the time of publication of their respective cases (mean, 5 months. Conclusion Primary carcinoid tumor arising within mature teratoma of the kidney is a rare tumor that typically presents with abdominal pain without carcinoid syndrome. It is not associated with local recurrence and metastasis, is surgically curable, and has excellent prognosis.

  5. Abdominal trauma

    Abdominal injury is an important cause of morbidity and mortality in childhood. Ten percent of trauma-related deaths are due to abdominal injury. Thousands of children are involved in auto accidents annually; many suffer severe internal injury. Child abuse is a second less frequent but equally serious cause of internal abdominal injury. The descriptions of McCort and Eisenstein and their associates in the 1960s first brought to attention the frequency and severity of visceral injury as important manifestations of the child abuse syndrome. Blunt abdominal trauma often causes multiple injuries; in the past, many children have been subjected to exploratory surgery to evaluate the extent of possible hidden injury. Since the advent of noninvasive radiologic imaging techniques including radionuclide scans and ultrasound and, especially, computed tomography (CT), the radiologist has been better able to assess (accurately) the extent of abdominal injury and thus allow conservative therapy in many cases. Penetrating abdominal trauma occurs following gunshot wounds, stabbing, and other similar injury. This is fortunately, a relatively uncommon occurrence in most pediatric centers and will not be discussed specifically here, although many principles of blunt trauma diagnosis are valid for evaluation of penetrating abdominal trauma. If there is any question that a wound has extended intraperitonelly, a sinogram with water-soluble contrast material allows quick, accurate diagnosis. The presence of large amounts of free intraperitoneal gas suggests penetrating injury to the colon or other gas-containing viscus and is generally considered an indication for surgery

  6. Abdominal trauma

    The potential for multiple intraperitoneal and retroperitoneal organ injuries often makes accurate clinical evaluation of abdominal trauma patients difficult. Additionally, patients may be unresponsive, have unreliable abdominal physical examinations, or have concurrent serious head and cervical spine injuries which delay diagnosis of and attention to abdominal problems. In these situations radiologic abdominal imaging is often requested. To expedite patient evaluation, close cooperation between the emergency physician and the radiologist is essential. It is the clinical stability of the traumatized patient that dictates the extent of radiologic imaging. Life-threatening hypotension, positive peritoneal signs, or clear evidence of penetrating abdominal injury are indications for immediate surgery. Stable patients with signs suggesting intra-abdominal injury will benefit by further radiologic evaluation with appropriate imaging modalities. The selection of an appropriate modality in any one clinical situation depends upon many criteria including accessibility to diagnostic equipment, the sensitivity and specificity of each technique, and the expertise and preference of the attending radiologist. A suggested scheme for evaluating abdominal trauma patients is presented. Most aspects of this evaluation scheme will be discussed in depth

O ovario, pouco aumentado de volume, é constituído por duas porções de tamanho sensivelmente egual, de consistencia firme, separadas, em sua superficie, por profundo sulco. Ao córte, tem a aparencia de tecido fibroso em cuja espessura existem numerosos pequenos cistos. Ao microscopio, os cistos são revestidos por epitelio descontinuo, despertando grande interesse o seu conteúdo. Este é formado por fibras e células com morfologia semelhante ás do cristalino. Sugerimos a possibilidade de que, no presente teratoma (Teratoma lentifer, de lens, lentis: cristalino, e ferre: produzir haja participado, de modo dominante, o ectodérme, e mesmo uma região circumscrita do ectodérme, a qual corresponderia aquela emque se desenvolve, habitualmente, a placa do cristalino (« Linsenplatte ».

  9. Abdominal ultrasonographic findings of Yersiniosis in children

    To review abdominal ultrasonography in Yersinia Pseudotuberculosis(YP) infection. From June 1993 through June 1994, abdominal ultrasonograms were reviewed in 36 patients with YP infection. The age of patients was from 4 to 14 years. A diagnosis of YP infection was made on the basis of isolation of YP from stool (n=15/36, 41.7%) and by documenting at least a minimum agglutination antibody titer of 1;160 or greater (n=34/36, 94.4%). Abdominal US findings were identified in 33/36 (91.7%) of patients with YP infection. US abnormalities included right lower quadrant abdominal lymphadenopathy in 28/36 (77.8%) of cases: increased bilateral renal cortical echogenecity with renal enlargement, 11/36 (30.6%) of cases:hepatosplenomegaly, 6/36 (16.7%) of cases: bowel wall thickening in termnal ileum and cecum, 4/36 (11.1%) of cases:and ascites, 2/36 (5.5%) of cases. Three patients revealed no abdominal sonographic finding. We conclude that abdominal US can help in the diagnosis of YP infection when US demonstrates multiple right lower quadrant abdominal lymphadenopathy, increased renal cortical echogenecity with renal enlargement, hepatosplenomegaly, intestinal wall thickening or ascites

    Mature teratomas are rarely located in the posterior mediastinum, and most mature teratomas are asymptomatic. Teratoma rupture into the adjacent lung and esophagus is possible but considering the rare entity of posterior mediastinal teratomas and the perforation rate, it is extremely unusual. We report a case of ruptured mature cystic teratoma located in the posterior mediastinum, showing fistula formation to the adjacent lung and esophagus, which presented with hemoptysis.

    To compare CT and US features of immature and mature teratomas of the ovary. We retrospectively reviewed CT and US findings of 11 patients with immature teratoma and 18 patients(20 cases) with mature teratoma. The tumors were classified into three groups on the basis of image findings : predominantly cystic(type I), predominantly solid(type II), and mixed cystic and solid(type III). All eleven cases of immature teratoma were of the mixed type(type III), showing multiple small(less than 2cm) nodular and linear calcifications and fatty nodules within the solid component and adjacent to the septa of the cystic component of the masses. In contrast, mature teratomas were predominantly cystic in six cases, predominantly solid in eight, and mixed in six cases. In five of six mixed type mature teratomes, calcified fatty nodules were fewer and larger than in immature teratomas. Immature teratoma may be diagnosed by the demonstration on CT or US of multiple small(less than 2cm) nodular and linear calcifications and fatty nodules in the solid and cystic components of the tumor.

    Malignant mixed germ cell tumors,though rare overall, are the most common type of malignant ovarian neoplasms in young and adolescent girls. These tumors are rapidly growing and can metastasize. We report a case of 13-yr-old girl who presented at SHKM GMC, Nalhar, Mewat, Haryana, India in December 2013 with huge abdominal lump of a malignant mixed germ cell tumor comprising both immature teratoma and embryonal carcinoma. This report illustrates the aggressiveness of this tumor and emphasises the need of early diagnosis and treatment. PMID:26870146

  19. US Diagnosis of Mature Cystic Teratomas of the Ovary:Morphologic Analysis of 112 Pathologically Proven Cases

    To establish the morphologic US classification of mature cystic teratoma of the ovary and document the reliable sonographic features in the diagnosis of this neoplasm. The study subjects comprised 103 patients with 112 pathologically proven, mature cystic teratomas. All patients underwent preoperative pelvic US in trans abdominal and/or trans vaginal approach. One radiologist retrospectively analyzed the US findings and the tumors were classified into 6 groups based on the morphologic US features. For each tumor, additional US findings, including posterior sonic shadowing, fat-fluid level and vascularity, were also evaluated. The common US patterns were hyper echoic area within a cyst (type IV: 36 tumors,32.1%), solid and cystic mass (type V: 32 tumors, 28.5%), and a diffusely hyper echoic mass (type VI: 25 tumors, 22.3%). All solid and cystic masses (type V) showed hyperechogenicity in at least one solid portion, resulting in hyperechogenicity within a mass being seen in 93 of the 112 tumors (83.0%), with pure cystic masses (types I-III) accounted for the remaining 19 tumors (17.1 %). Of the 112 tumors, 68 (67.1%) showed posterior sonic shadowing which was demonstrated only in the hyper echoic area of types IV-VI. Any adnexal masses representing a hyper echoic area within a cyst, solid and cystic tumors containing hyperechogenicity or diffusely hyper echoic mass, especially when accompanied by posterior sonic shadowing, should be suspected as indicative of mature cystic teratoma

    Teratomas are among the most common tumors of childhood, but craniofacial teratomas are rare. They can be diagnosed antenatally. Craniofacial teratomas may cause airway obstruction in the newborn. We present a case of a newborn male child who was diagnosed to have a facial tumor in the 8th month of gestation. He was delivered normally and had no respiratory or feeding difficulties. He was also found to have a cleft palate. Serum alpha fetoprotein levels were normal. He underwent excision on day of life 9. At 11 months follow-up, he is well with no evidence of recurrence and good functional outcome.

  3. Abdominal Sepsis.

    De Waele, Jan J

    2016-08-01

    Abdominal infections are an important challenge for the intensive care physician. In an era of increasing antimicrobial resistance, selecting the appropriate regimen is important and, with new drugs coming to the market, correct use is important more than ever before and abdominal infections are an excellent target for antimicrobial stewardship programs. Biomarkers may be helpful, but their exact role in managing abdominal infections remains incompletely understood. Source control also remains an ongoing conundrum, and evidence is increasing that its importance supersedes the impact of antibiotic therapy. New strategies such as open abdomen management may offer added benefit in severely ill patients, but more data are needed to identify its exact role. The role of fungi and the need for antifungal coverage, on the other hand, have been investigated extensively in recent years, but at this point, it remains unclear who requires empirical as well as directed therapy.

  5. Surgical Anatomy of Large Retroperitoneal Teratomas in Infants: Report of Two Cases

    Ralf-Bodo Tröbs

    2008-01-01

    Full Text Available We report on two infants of 11 and 12 months of age, respectively, with large solid-cystic retroperitoneal tumors. Complete resection was achieved, and both children are doing well over a follow-up of more than 17 months. The presented paper focuses on surgical anatomy of this very rare type of tumor. Teratomas were located mainly within the upper abdominal cavity, and both tumors displaced the pancreas in an anterior position. The following anatomical features were observed (1 displacement of surrounding organs, (2 deformation and elongation of large retroperitoneal vessels, (3 fibrous incorporation of large vessels by the tumor pseudocapsule, (4 wrapping of anterior aortic branches by lobes and fingers of the tumor.

    Mature teratoma of the pancreas is an unusual tumor. Like all teratomas it results from abnormal embryonal development of toti potent cells. Their contents may vary and may consist of ectodermal, endodermal, and mesodermal tissues. The radiologic appearance of these lesions depends on the proportions of various tissues of which they are composed. We report, to our knowledge, the first description of its CT and MR appearances.

    Ovarian teratomas (OTs) are the most common germ cell neoplasm. They include mature cystic teratomas, monodermal teratomas (neural tumors, struma ovarii, carcinoid tumors) and immature teratomas. Teratomas are the most common benign ovarian neoplasms in women less than 45 years old. OTs are usually characterized by ultrasound (US) and magnetic resonance (MR) whereas they are usually an incidental finding on CT. The purpose of this paper is to review the most common types of teratomas and to describe CT, US and MR imaging features of the various types of mature and immature OTs.

  9. Teratoma of the lumbosacral region: a case report

    Khan Roobina

    2011-08-01

    Full Text Available Abstract Introduction Teratoma is a tumor that usually arises from one or more germ layers. They are most commonly found in the sacrococcygeal region and have a female preponderance. We present a very rare case of a boy with a benign cystic teratoma in the lumbosacral region. Case presentation A 16-year-old Indian boy presented to our hospital with a history of a lump in the lower back region since birth. Initially, it was small, but its size increased gradually over time to a size of 15 cm × 15 cm at presentation. There were no other associated abnormalities. Investigations revealed the lump to be a benign cystic teratoma. The patient underwent surgery, and the whole tumor, from its base to the vertebrae, was excised. Bisection of the tumor revealed that it contained hair and pultaceous material consistent with a teratoma, which was later confirmed by histopathologic examination. Conclusion Benign cystic teratomas should be diagnosed and managed aggressively because they generally have a greater tendency to progress toward malignancy. After extensively searching the case report database, we arrived at the conclusion that this was a rare case of a benign cystic teratoma in the lumbosacral region in a boy.

  11. Sacrococcygeal fetus in fetu mimicking a teratoma: A rare case with brain tissue and an immature teratoma component

    Fetus in fetu is a rare, nonviable, malformed parasitic twin, which grows within the body of its partner. It has been known as being almost always anencephalic and rarely reported to have an immature teratoma component. We report a case of a sacrococcygeal fetus in fetu with brain tissue seen on both imaging studies and pathologic specimens, containing an immature teratoma component on pathologic examinations. Imaging studies including plain radiography were very helpful for the correct diagnosis

  12. STUDY OF HISTOMORPHOLOGICAL CHANGES OF TERATOMAS I N TERTIARY CARE HOSPITAL

    Sushma

    2013-03-01

    Full Text Available ABSTRACT : Teratomas are the germ cell tumors composed of mul tiple cell types derived from one or more of the three germ layers.Teratomas rang e from benign well differentiated [mature] cystic lesions to those that are solid and malignan t [immature].Additionally, teratomas may be monodermal and highly specialized. Rarely, within so me mature teratomas, certain elements like squamous component undergo malignant transform ation.Teratomas are known to occur at birth and are derived from pleuripotent germ cells and embryonic cells. Teratomas of embryonic origin are congenital and are seen in the midline of the body – skull, neck, mediastinum, retroperitoneum, and coccyx.Teratomas d erived from the germ cells are seen in testis in men and ovaries in women. AIMS: This prospective and retrospective study was conducted to determine the frequency of the teratom as occurring in various sites along with their histomorphological presentations. MATERIALS AND METHODS : The study was conducted at Rajarajeswari Medical College and Hospi tal between January 2010 to December 2012 in the Department of Pathology. Morphological an d histopathological features of teratomas were studied. RESULTS: Teratomas were more common in females between 25- 35yrs.Most of the teratomas were seen in ovaries f ollowed by retroperitoneum and sacrococcygeal region.87% of teratomas diagnosed we re of mature cystic teratoma with histologic grading 0 and remaining 13% showed malig nant transformation. CONCLUSION: Mature teratomas are typically benign and found mor e frequently in women and there is risk of malignant transformation.

    An, Hyo Jeong; Jung, Yong Han; Yoon, Hye Kyoung; Jung, Soo Jin

    2013-08-01

    Roughly 1% of mature cystic teratomas undergo malignant transformation. In particular, cutaneous-type adnexal neoplasms may occur in mature cystic teratomas. Sebaceous carcinomas, which arise from mature cystic teratomas, have rarely been observed, with only seven cases previously reported. Here, we present a case of a 69-year-old female who had pelvic pain for two weeks and who subsequently underwent bilateral salpingo-oophorectomy and hysterectomy. Her left ovary showed a unilocular cyst, measuring 22.0 cm in diameter, filled with sebaceous material and a few hairs. A luminally-protruding solid mass measuring 4.0 cm in diameter was also noted. Microscopic findings revealed lobular or diffusely arranged basophilic, atypical sebaceous cells connected to a typical mature cystic teratoma. Tumor cells demonstrated positive immunoreactivity for high molecular weight cytokeratin, cytokeratin 7, cytokeratin 19, epithelial membrane antigen, and carcinoembryonic antigen. Here, we present a case of sebaceous carcinoma arising from a mature cystic teratoma along with a review of previously published reports. PMID:24009635

    A 73-year-old man was transferred for treatment of abdominal aortic aneurysm. He had no history of abdominal surgeries. Grafting between the infra-renal abdominal aorta and the bilateral common iliac arteries was performed. Proximal and distal cross clamps were applied for grafting. He developed chylous ascites on the 5th post-operative day, 2 days after initiation of oral intake. Fortunately, he responded to treatment with total parenteral hyper-alimentation for 10 days, followed by a low-fat diet. There was no recurrence of ascites. PMID:27087873

    1983-12-01

    Primary malignant mediastinal teratoma is a rare tumour previously regarded as inevitably fatal. In a series of eight male patients with a mean age of 24 years five remain alive and well. All patients showed raised serum concentrations of human chorionic gonadotrophin or alpha fetoprotein. The patients were treated with intermittent combination chemotherapy that included cisplatin. Six patients responded to chemotherapy with a fall in human chorionic gonadotrophin or alpha fetoprotein to near normal levels and they then had radical excision of the remaining tumour. Living malignant tumour was found in four of the specimens and these patients received postoperative chemotherapy. One patient died after eight months and the remaining five patients are alive and well 13-136 months after the start of treatment. The two patients who did not undergo surgery died at one month and 15 months. Intermittent combination chemotherapy and carefully timed radical excision of these tumours would appear to have produced better results than have been reported in other series. PMID:6198739

    Teratoma of the head and neck is a rare lesion comprising 6 % of all teratomas, with only 3 % occurring in the cervical region [1]. Most are non-malignant lesions consisting of a variety of tissues of variable maturity, commonly with neuroepithelial and thyroid elements. They often present as a large cystic mass in the neck of a neonate or infant and frequently cause respiratory embarrassment due to local mass effect necessitating urgent surgical intervention. They may be difficult to distinguish from cystic hygromas, both clinically and radiologically. Imaging plays an important role in the assessment of these lesions, especially in preparation for surgery. We present a case of cervical teratoma and emphasise the role of MRI. (orig.)

    2008-12-01

    Full Text Available Mature teratomas are the most common type of mediastinal germ cell tumors. They typically occur in young adults (15 to 35 years and 95% of these teratomas occur in the anterior mediastinum. Herein, we report a case of a huge mediastinal teratoma in a 16-year-old boy who presented with a history of chest pain, cough, exertional dyspnea, and fever. Chest X-ray and spiral computed tomography (CT revealed a bulky mass of 20×15 cm in the right side of the posterior mediastinum. The operative finding was a large cystic mass in the posterior mediastinum adherent to the neighbor organs. The cyst was filled with sebum, hair and calcified materials. The resected tumor was in the posterior mediastinum, although most of these tumors occur in the anterior mediastinum. To the best of our knowledge, this is the first documented report in Iran.

  8. Radiofrequency Coblation of Congenital Nasopharyngeal Teratoma: A Novel Technique

    Sang Yun Hwang

    2015-01-01

    Full Text Available Introduction. Congenital nasopharyngeal teratomas are rare tumours that pose difficulties in diagnosis and surgical management. We report the first use of radiofrequency coblation in the management of such tumours. Case Report. A premature baby with a perinatal diagnosis of a large, obstructing nasooropharyngeal mass was referred to the ENT service for further investigations and management. The initial biopsy was suggestive of a neuroblastoma, but the tumour demonstrated rapid growth despite appropriate chemotherapy. In a novel use of radiofrequency coblation, the nasooropharyngeal mass was completely excised, with the final histopathology revealing a congenital nasopharyngeal teratoma. Conclusion. We report the first use of radiofrequency coblation to excise a congenital nasopharyngeal teratoma and discuss its advantages.

    Usually slow-growing and benign, mature mediastinal teratomas are rare clinical entities. They may be complicated by rupture into the pleural or pericardial spaces, lungs, or bronchi. Complete surgical resection is the treatment of choice and is usually curative. We report the unusual case of a 24-year-old woman presenting 15 weeks postpartum with a huge ruptured mature mediastinal teratoma superinfected with Mycobacterium avium Catastrophic bleeding from the superior vena cava was encountered on mobilization of adhesions attached to it, requiring extracorporeal membrane oxygenator support for control. Histopathological examination confirmed a 12.0 × 7.8 × 4.5-cm differentiated teratoma without malignant transformation. PMID:27440933

    Miyasaka, Aki; Nishikawa, Tadaaki; Kozawa, Eito; Yasuda, Masanori; Fujiwara, Keiichi; Hasegawa, Kosei

    2016-01-01

    Purpose To describe the postoperative progressive course of advanced-stage adenocarcinoma arising from a mature cystic teratoma (MCT) and review the literature regarding this disease. Methods A 59-year-old woman visited our hospital with an abdominal mass. Laparotomy showed enlargement of the left ovary and dissemination throughout the abdominal and pelvic cavities. The diagnosis was FIGO stage IIIB adenocarcinoma arising from a MCT. We report this case in detail with a review of the literature. Results A literature search yielded 9 cases of stage III adenocarcinoma with malignant transformation. Six of these 9 patients died within 12 months after diagnosis. Of the 8 patients who underwent postoperative chemotherapy, 3 survived for over 39 months. The review indicates that prognosis of adenocarcinoma is as poor as that for squamous cell carcinoma arising from a MCT. Conclusions In general, as with this case, prognosis of advanced adenocarcinoma associated with a MCT is poor. However, we should be aware that not all patients are resistant to chemotherapy.

  11. Teratoma: from spontaneous tumors to the pluripotency/malignancy assay.

    Bulic-Jakus, Floriana; Katusic Bojanac, Ana; Juric-Lekic, Gordana; Vlahovic, Maja; Sincic, Nino

    2016-01-01

    A teratoma is a benign tumor containing a mixture of differentiated tissues and organotypic derivatives of the three germ layers, while a teratocarcinoma also contains embryonal carcinoma cells (EC cells). Experimental teratomas and teratocarcinomas have been derived from early mammalian embryos transplanted into the adult animal (ectopic sites). In the rat, the pluripotency of the transplanted epiblast was demonstrated and a quantifiable restriction of developmental potential persisted after subsequent transplantation of chemically defined cultivated postimplantation embryos. The rat is nonpermissive for teratocarcinoma development and rat pluripotent cell lines have been established only recently. Transplantation of mouse embryos, epiblast, or embryonic stem cells (mESCs) gave rise to teratocarcinomas. The pluripotency of reprogrammed human cells has been tested by a 'gold standard' trilaminar teratoma assay in immunocompromised mice in vivo. Human pluripotent stem cells proposed for use in regenerative medicine such as human embryonic stem cell (hESC), human nuclear-transfer/therapeutic cloning embryonic stem cell (NT-ESC), or human induced pluripotent stem cell (hiPSC) lines, once differentiated in vitro to the desired cell type, should be again tested in a long-term animal teratoma assay to exclude their malignancy. Such an approach led to a recently implemented human therapy with retinal pigmented epithelium. For greater biosafety, the teratoma assay should be standardized and complemented by assessments of mutations/epimutations, RNA/protein expression, and possible immunogenicity of autologous pluripotent cells. Furthermore, the standardized teratoma assay should be directed more to the assessment of EC/malignant cell features than of differentiated tissues, especially after a unique case of human therapy with neural stem cells was found to lead to malignancy.

    An adenocarcinoma arising from mature teratoma is one form of teratoma with malignant transformation. It is extremely rare but highly malignant. The authors report two patients with adenocarcinomas arising from primary retroperitoneal teratomas. The CT and MRI findings of the tumors are presented with emphasis on imaging features implying the presence of malignant transformation and differing from those of pure benign mature teratoma. Correct diagnosis of the presence of malignant transformation from a benign mature teratoma can be made as early as possible by awareness of the imaging features. (orig.)

  15. Is It Necessary to Perform Surgical Staging in Patients with Giant Immature Ovarian Teratomas Mimicking Mature Cystic Teratoma at Frozen Section

    Ismail Guler

    2013-09-01

    Full Text Available Giant mature teratomas (>20 cm in diameters sometimes may contain malignant immature elements or tissues. These small foci of immature tissues could be missed at frozen section resulting inadequate initial surgical intervention. There is no large series in the literature either showing the accuracy of frozen section on huge ovarian teratomas or concerning the adequate surgical approach at the initial surgery for giant immature teratomas diagnosed as mature cystic teratomas at frozen section in patients with elevated tumor markers. We presented a case with unilateral giant immature ovarian teratoma and peritoneal gliomatosis which diagnosed as mature cystic teratoma at frozen section. Although elevated tumor markers (CA-125, AFP, CA-19,9 CEA, and lactate dehydrogenase, ascites and peritoneal implants were suggested malignant disease, staging surgery was not performed due to the benign report of frozen section. Since the patients having peritoneal implants of mature glial tissue have an excellent prognosis regardless of the grade of the ovarian teratomas, it may be suggested that surgical staging at the initial operation may not be performed in patients with giant immature teratoma diagnosed as mature teratoma at frozen section despite to the elevated tumor markers, presence of ascites or mature peritoneal implants. seems that using it in infertile patients has beneficial effects.

    Stanhiser, Jamie; Mahdi, Haider; Rosa, Gabriela; Harper, Holly; Shepard, Dale; Rose, Peter G; Roma, Andres A

    2016-03-01

    We report our experience with prostatic-type tissue in ovarian teratomas, and in particular we highlight a case of prostatic-type adenocarcinoma arising within a mature cystic ovarian teratoma in a 32-yr-old woman. On gross examination, the cyst consisted of typical features of a dermoid cyst. Closer examination revealed a single 1.5-cm solid nodule within the cyst. Microscopically, it was composed of a small cyst-like structure lined by urothelium and to one side glandular and stromal tissue consistent with prostate parenchyma. Within the prostatic-type tissue, there were malignant glands morphologically and immunohistochemically supportive of prostatic-type adenocarcinoma Gleason score 3+3=6. There were also areas consistent with high-grade prostatic intraepithelial neoplasia. Although there are several reports in the literature of benign prostatic-type tissue arising within ovarian as well as testicular teratomas, to our knowledge, prostatic-type adenocarcinoma arising in a mature ovarian teratoma is an extremely rare phenomenon, with only 1 previous report in the literature.

    An intracranial teratoma in which six distinct dysmorphic fetuses were included was studied at autopsy. Karyotopic studies showed a normal chromosomal number in the child and the same karyotype in the three tumoral parts that were examined. This is the second tumor of this type reported. Copyripht (

    To differentiate mature and immature ovarian teratomas, using CT findings. The CT findings of ten mature ovarian teratomas (in one patient, bilateral) and ten which were immature were compared, using statistical analysis. Images were evaluated for size, margins, architecture, contents (mural nodules, fat, calcification), septa, local invasion and distant metastasis. These findings were compared with pathologic findings. Of the ten mature tumors, nine were well defined and predominantly cystic in internal architecture, and one was mixed. Mural nodules were found in six tumor, fat in all, distinct calcification in seven, and regular septa in three lesions. Of the ten immature humors, eight had irregular margins. Seven were predominantly solid in internal architecture and irregularly enhanced, two were mixed, and one was mainly cystic. Fat was detected in five lesions, indistinct scattered calcification in six, irregular septa in three, and local invasion of distant metastasis in four patients. Compared with mature ovarian teratomas, those that are immature tend to show CT findings of marginal irregularity, solid mass with irregular enhacement, scattered indistinct calcifications, septal irregularity, local invasion or distant metastasis. Our experience suggests that these findings may be helpful in differentiation of mature and immature ovarian teratomas.

    Intracranial teratomas are the most common intracranial tumor in newborns. Their clinical symptoms are ambiguous but they have a characteristic pattern of a bulky midline lesion with a solid component, multiple loculated cysts and occasionally calcifications. This pattern is easily evident on cranial MR examination.

    Teratomas are very rare intracranial tumors and cytogenetic information on this group remains rare. We report a case of a mature teratoma with abnormal +21 trisomy in tumor karyotype ocurring in a non-Down syndrome(DS) infant. Additionally, the evidence for the contribution of chromosome 21 trisomy in this neoplasia are briefly reviewed. The 6-month-old male baby presented with a posterior fossa tumor. Histological evaluation of tumor specimen showed a mature teratoma composed of fully differentiated ectodermal, mesodermal and endodermal components. Although somatic karyotyping of the index case was normal, composite tumor karyotype depicted 47,XY,+21[6]/46,XY[6]. Besides previous reports of children with DS and intracranial teratomas, this is the first report to describe the occurrence of an isolated chromosome 21 trisomy within the tumor of a non-DS child. The participation of chromosome 21 in this rare pediatric tumor, either somatic or restricted to tumor specimen,may deserve special interest and further investigation. PMID:24812702

    Gastric teratoma is an infrequent gastric lesions,is short of 1% in teratoma,has commonly occur in male infant,and particularly has diseased within 3 months.36 cases with gastric teratoma who had been reported from 1996 to 2002 were newborns excluding 3 cases of adults with 2 male cases and 1 female case and 7 cases of children.Gastric teratoma has the regular systematic report less than thousand cases,since Eusterman has reported the first male patient aged 31 in 1992.To report one case of gastric teratoma which has the main manifestations of abdominal distension and abdominal mass without specific,is easy of misdiagnosis,has commonly occur in male infant within 3 months and much infrequent in adult female.%胃畸胎瘤是一种很罕见的胃部病变,在畸胎瘤中所占比例不足1%,一般好发于男性婴幼儿,特别是出生3个月内的发病占绝大多数。国内1996~2002年间共报告36例,其中除3例成年人(男2例,女1例),7例幼儿外,均发生于新生儿。而自1922年Eusterman首次报告1例31岁男性患者以来,目前胃畸胎瘤正规系统报告尚不足千例。该病以腹胀、腹部肿块为主要临床表现,无特异性,易误诊。因本病好发于出生3个月内的男婴,而成年女性则极为罕见,现报道1例。

  7. Abdominal trauma

    Radiologic evaluation of abdominal trauma must provide a quick and accurate assessment of the lesions in order to improve the management of the patient. The technique used varies depending on the mechanism of the trauma (blunt trauma or stab wounds) and the hemodynamic status. Radiologic evaluation is usually performed in blunt trauma whereas stab wound trauma is usually explored surgically. The various techniques available are standard radiographs, ultrasonography, computed tomography and arteriography. The role of magnetic resonance imaging in the immediate evaluation is still not well defined. It appears to be useful method in the delayed evaluation of diaphragmatic trauma. Computed tomography is the method most commonly performed in trauma patients. This technique is accurate and allows correct assessment of the lesions. The disadvantages are the radiation induced and the need for a hemo-dynamically stable patient. The aim of the radiologic evaluation is to provide the clinicians with an accurate description of the lesions. It can help in the management of the patient usually in association with clinical and laboratory data. It can also guide interventional procedures (drainage, embolization...). Finally, it allows radiographic follow-up when conservative treatment is performed. (authors). 26 refs., 11 figs., 1 tab

Methods: 30 patients of young women were managed in transvaginal ovarian teratoma resection. To observe the operation indications, the overall operating time, the estimated operative blood loss, hospital stay, postoperative anal exhaust time were explored. Results: transvaginal ovarian teratoma cystectomy were successfully completed without conversion to laparotomy. The mean operative time was 22 minutes,t he estimated blood loss was 19mL .mean anal exhaust time was 18.4 hours, The average hospital stay was 3.2 days. Conclusion: transvaginal ovarian teratoma cystectomy is a good choice when the indication of operation are managed properly with minimally invasive operation,rapid postoperative recovery, leaving no scar of abdominal wall.

  9. CT of hemodynamically unstable abdominal trauma

    This article is an appraisal of the use of CT in the management of patients with unstable abdominal trauma. We examined 41 patients with abdominal trauma using noncontrast dynamic CT. In 17 patients a postcontrast dynamic CT was also carried out. On CT, 25 patients had hemoperitoneum. Thirteen patients had splenic, 12 hepatic, 6 pancreatic, 8 bowel and mesenteric, 12 renal and 2 vascular injuries. Seven patients had retroperitoneal and 2 patients adrenal hematomas. All but five lesions (three renal, one pancreatic, and one splenic) were hypodense when CT was performed earlier than 8 h following the injury. Postcontrast studies (n = 17), revealed 4 splenic, 3 hepatic, 1 pancreatic, 3 renal, and 2 bowel and mesenteric injuries beyond what was found on noncontrast CT. Surgical confirmation (n = 21) was obtained in 81.81 % of splenic, 66.66 % of hepatic, 83.33 % of pancreatic, 100 % of renal, 100 % of retroperitoneal, and 85.71 % of bowel and mesenteric injuries. The majority of false diagnoses was obtained with noncontrast studies. Computed tomography is a remarkable method for evaluation and management of patients with hemodynamically unstable abdominal trauma, but only if it is revealed in the emergency room. Contrast injection, when it could be done, revealed lesions that were not suspected on initial plain scans. (orig.)

    Germ cell tumors account for a majority of all ovarian tumors. Ninety five percent of germ cell tumors are dermoid cysts (Mature cystic teratoma). Carcinomas arising from mature cystic teratoma are quite rare. The most common malignancy being Squamous cell carcinoma (75%). In the present study we report a case of Squamous cell carcinoma arising in a mature cystic teratoma. A 45 year old female presented with mass in abdomen, pain abdomen and dysuria since one month.
