Background: Teratomas can occur in the umbilical cord, and may or may not be associated with other congenital abnormalities. Case report: This 35-year-old primigravida gave birth 37–38 weeks to a 3290-g normal female. The umbilical cord, at 10 cm from the abdominal insertion, had an 8 cm mature teratoma. Work-up revealed no other abnormalities. Discussion: Mature teratomas may occur in the umbilical cord, and may or may not have additional clinical sequalae. [ABSTRACT FROM AUTHOR]

Aim: Tumorigenicity of residual undifferentiated induced pluripotent stem cells (iPSCs) is a major concern. The purpose of this study was to investigate the optimal conditions for removal of iPSCs using R-17F antibody, which recognizes specific glycosphingolipids glycans on undifferentiated iPSCs and exhibits selective cytotoxicity to iPSCs. Materials & methods: After adding of R-17F and secondary antibody to co-cultured iPSCs and chondrocytes, residual iPSCs were quantitatively evaluated by iPS specific glycome analysis. Results: Undifferentiated iPSCs were sufficiently removed using R-17F in combination with an equal amount of a secondary antibody. Furthermore, teratomas were not observed upon transplantation of co-cultured cells pretreated under the same conditions into testes of immunodeficient mice. Conclusion: This removal method incorporating R-17F may be useful for regenerative medicine using iPSCs. [ABSTRACT FROM AUTHOR]

This article discusses a case report of a 24-year-old woman with a rare combination of immature teratoma (IMT) and yolk sac tumor (YST) in her left ovary. The patient underwent surgery to remove the tumor, and subsequent histological analysis confirmed the diagnosis. The patient did not receive chemotherapy due to her desire to preserve fertility. She has been followed up regularly for five years without any recurrence of the disease. The article emphasizes the importance of considering rare pathological forms of malignant ovarian germ cell tumors (MOGCT) and the application of fertility-sparing surgical strategies. It also highlights the need for long-term monitoring and psychological support for young patients with MOGCT. [Extracted from the article]

Objective: We sought to explore pre-existing medical disorders as risk factors for preeclampsia as thoroughly as possible. Methods: A case-control design. A group of 1,652 patients were identified as the preeclampsia group, and another randomly selected 4,500 patients were identified as the non-preeclampsia group. Results: Mature ovarian teratoma (adjusted odds ratio [OR] 7.69, 95% CI 1.58-37.53), uterine fibroids (adjusted OR 2.24, 95% CI 1.28-3.92) and pregestational hypothyroidism (adjusted OR 5.17, 95% CI 2.43-11.00), were significantly correlated with preeclampsia. Conclusions: Mature ovarian teratoma, uterine fibroids and pregestational hypothyroidism may also contribute to the incidence of preeclampsia. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 21-year-old woman diagnosed with oligodendroglioma from mature cystic teratoma. Topics discussed include the medical history and records of the patient, her physical examination, an overview of oligodendroglioma, its diagnosis, risk factors and its treatment options.

This article discusses a case report of a 24-year-old woman with a rare combination of immature teratoma (IMT) and islets of a yolk-sac tumor (YST) in her left ovary. The patient underwent surgery to remove the tumor and preserve fertility. The tumor was successfully removed, and the patient has remained disease-free for five years. The article emphasizes the importance of considering rare pathohistological forms of malignant ovarian germ cell tumors (MOGCT) and the need for long-term follow-up and psychological support for patients. The authors also highlight the emerging field of oncofertility, which focuses on preserving fertility in cancer patients. [Extracted from the article]

A cleft palate results from incomplete fusion of the lateral palatine processes, the median nasal septum and the median palatine process. This case report describes a rare case of congenital teratoma originating from the nasal septum that may have interfered with the fusion of the palatal shelves during embryonic development, resulting in a cleft palate. An infant girl was born at 40 weeks of gestation weighing 3020 g with a complete cleft palate associated with a large central nasopharyngeal tumour. Computed tomography (CT) of the head showed a well defined mass of mixed density. The tumour was attached to the nasal septum in direct contact with the cleft palate. A biopsy confirmed the teratoma. Tumour resection was performed at 5 months, soft palate reconstruction at 7 months and hard palate closure at 14 months. There was no sign of local recurrence 1 year later. Most teratomas are benign and the prognosis is usually good. However, recurrence is not rare if germ cell carcinomatous foci are present within the teratoma. For these reasons, we advocate the use of a two-stage procedure in which closure of the cleft palate is postponed until histological examination confirms complete excision of the teratoma.

Ovarian mature cystic teratoma (OMCT) is an ovarian benign neoplasm with excellent prognosis presenting components of the three germinal layers. However, transformation into a malignant neoplasm is a rare event (so-called somatic transformation). In most of the cases, the malignant component expresses as epidermoid carcinoma, but occasionally central nervous system tumors occur. Some of the previously reported tumors are astrocytoma, glioblastoma, and ependymoma. Somatic transformation of OMCT into an oligodendroglioma is exceptional. We report a 19-year-old female with a left OMCT with an area of oligonedroglial cells proliferation characterized by immunohistochemical studies with positivity for GFAP and S100, with a low Ki67 index (5%). Additionally, electron microscopy revealed oligodendrocytes with parallel bundles of cytoplasmic intermediate filaments, confirming the oligodendroglial nature of the proliferation. The patient was treated only with left oophorectomy, and three and half years after surgery, there is no evidence of disease. [ABSTRACT FROM AUTHOR]

We aimed to evaluate the risk factors for recurrence of surgically managed ovarian mature cystic teratoma (MCT). A total of 178 women with MCT managed surgically at our clinic were included in this retrospective study. The cases were followed for a minimum of 34 months. Risk factors recorded were age, gravidity, diameter of MCT, tumour markers, bilaterality, operation time and recurrence time. One hundred forty-one women (79.2%) underwent laparoscopy and the other thirty-seven patients (20.8%) underwent laparotomy. The mean age of patients with cyst recurrence was significantly lower than that of patients without recurrence (p = 0.02). There was a significantly lower median gravidity and parity in this group. The capacity of younger age, lower gravidity and parity in predicting the recurrence of ovarian MCT was analysed using receiver operating characteristic curve analysis. The cut-off value of age, number of gravidity and parity was 26, 1 and 0, respectively. In conclusion, younger age and lower gravidity and parity were predictive of recurrence due to a more conservative approach in young and nulliparous patients. Therefore, we suggest regular follow-up visits during the postoperative period, especially for younger patients and those with lower numbers of gravidity and parity. [ABSTRACT FROM AUTHOR]

The orbit is a relatively small anatomical area. Space-occupying lesions generally increase orbital volume and can result in proptosis of the globe and adversely affect visual acuity and extraocular muscle function, leading to decreased vision and diplopia. Orbital tumors comprise a group of diverse tumors from benign to malignant diseases. Orbital tumors can be classified into pediatric (≤18 years) or adult (>18 years) orbital tumors. The most common pediatric orbital tumors are dermoid cyst, capillary hemangioma and rhabdomyosarcoma. The top adult orbital tumors are lymphoid tumors, cavernous hemangioma, lacrimal gland tumors and idiopathic orbital inflammation. Several important developments have occurred both in clinical management and pathologic evaluation of orbital tumors. A new classification system (ISSVA) was devised for orbital vascular tumors. Capillary hemangiomas are now treated preferentially with oral β-blocker agents, and lymphangiomas can be reduced with sildenafil. [ABSTRACT FROM PUBLISHER]

The introduction of fetal magnetic resonance imaging (MRI) has improved the prenatal evaluation of uterine, placental and fetal anatomy. However, its utilization has mostly been restricted to fetal central nervous system anomalies. We review how adjunct fetal MRI was performed and diagnosis of cystic type IV sacrococcygeal teratoma was made. We also discuss the clinical relevance of fetal MRI in differentiating this lesion from other selected abdominal/pelvic cystic malformations and lesions. [ABSTRACT FROM AUTHOR]

The article presents a case study of 38-year-old pregnant patient referred to the foetal diagnostic clinic for an evaluation of a complex foetal abdominal mass found during ultrasound. The differential diagnosis included foetus-in-fetu versus fetiform teratoma. The mass was removed surgically on the sixth day after the baby was born by vaginal delivery, given the potential for obstruction and malignant transformation.

Primary ovarian malignant melanoma arising in teratomatous component of germ cell tumors is seen extremely rare with most reports being only of single cases and small series in reproductive aged woman and mostly from cystic teratoma, whereas information on pediatric presentation is sparse. This case is reported for being extremely rare tumor. [ABSTRACT FROM AUTHOR]

Epignathus is a very rare fetal tumor. We report a case of fast-growing giant epignathus with severe distortion of the right part of the face and orbit. A thorough prenatal work-up was performed by the association of Magnetic Resonance Imaging and Ultrasonography. A multidisciplinary approach was crucial to assess the operability and provide careful counseling to help parents understand and reach decision. [ABSTRACT FROM AUTHOR]

Rhabdoid tumors are rare but highly aggressive tumors with a predilection for infants and young children. The majority of these tumors harbor biallelic mutations in SMARCB1/INI1/hSNF5. Rather rare cases with mutations in other SWI/SNF core members such as BRG1 are on record. Rhabdoid tumors have only recently been registered and treated according to specifically designed treatment recommendations and in the framework of clinical trials. Within the last decade, prognosis has improved significantly but at least 50% of patients still relapse and subsequently almost inevitably succumb to their disease. This review summarizes past and current clinical approaches and presents an overview of the rationales for targeted therapy with potential for future clinical treatment trials for rhabdoid tumors.

Conclusion: The histological findings and quantitative measurements demonstrated that there were differences in teratoma formation according to the site of implantation. Elucidating the mechanisms of the teratoma formation caused by the site of implantation moves the field another step closer to clinical use of induced pluripotent stem (iPS) cells for tracheal regeneration. Objectives: Our previous study demonstrated the potential for iPS cells to be used as a new cell source for tracheal regeneration. However, teratoma formation remains a major problem. Implantation site-dependent differences in teratoma formation have been reported. In this study, the teratoma-forming propensity after implantation into tracheal defects and abdominal subcutaneous tissue was examined histologically and quantitatively. Methods: Mouse iPS cells were cultured in artificial material under various conditions. After cultivation in vitro, artificial materials with cultured iPS cells were then implanted into cervical tissue around tracheal defects and into abdominal subcutaneous tissue in nude rats. Teratoma formation was evaluated histologically and quantitatively with measurement of maximum diameter (MD). Results: Teratoma was observed in 10 of 11 rats with cervical tissue around tracheal defects and in 3 of 11 rats with abdominal subcutaneous tissue implants. The average MD was 5.36 mm in the trachea and 0.97 mm in the abdomen. [ABSTRACT FROM AUTHOR]

Background: Mediastinal germ cell tumors (GCTs) are rare and usually located in anterior mediastinum. We aimed to review clinical and pathological characteristics of these tumors. Procedure: Between 1973 and 2011, 24 children with mediastinal GCTs were diagnosed. Hospital files were reviewed for presenting complaints, clinical, radiological and other laboratory data, surgical practices, treatments, and outcomes. Results: Median age was 4.5 years (0.2-16) (male/female: 10/14). Most common initial complaints were dyspnea, cough, anorexia/fatigue, fever, and chest pain. Primary tumors were located in anterior mediastinum ( n = 22), posterior mediastinum ( n = 1), and sternum ( n = 1). Thirteen of 24 cases had mature teratomas (54.2%); four (16.7%) endodermal sinus tumor (EST); four (16.7%) immature teratomas; and one (4.2%) each of embryonal carcinoma, teratocarcinoma, and malignant teratoma. Mature teratomas underwent only surgical resection and were under follow-up without disease. Four cases with ESTs received chemotherapy and radiotherapy ( n = 3), three underwent surgical resections: three died, one was followed for 284 months in remission. All but one immature teratomas were treated with surgery and all were under follow-up without disease. Two patients with embryonal carcinoma and malignant teratoma didn't undergo surgery; both received chemotherapy and radiotherapy but died with disease. The patient with teratocarcinoma was treated with surgery and chemotherapy but died with disease. Conclusions: No adjuvant therapy is needed for mature teratomas. Immature teratomas must be under close follow-up for recurrences. Prognosis for mediastinal malignant GCTs was poor. These cases need intensive chemotherapies and effective local control measures as surgery -/+ radiotherapy to ensure long-term survival. [ABSTRACT FROM AUTHOR]

Ectopic thyroid tissue in ovarian teratoma or in struma ovarii appears to be histologically identical to the thyroid gland tissue and may virtually exhibit all the pathological patterns found in the thyroid gland. However, the concurrent lymphocytic infiltration of the thyroid gland, as found in Hashimoto's thyroiditis, and of the ectopic thyroid tissue is extremely rare. We describe the case of an 18-years old patient, in which a right ovarian 4 cm cyst has been found during pelvic ultrasound exam. The cyst was resected and microscopic examination of the mass revealed a mature cystic teratoma in which epidermal-like lining with skin adnexa, admixed with respiratory type epithelium, and areas of mature fatty, chondroid and dentigerous tissues were found. In a peripheral area of 0.7 cm × 0.5 cm, a prominent lymphocytic infiltrate surrounding thyroid follicles was identifiable. Thyroid function evaluation at different time points after surgery, revealed the development of mild hypothyroidism. Anti-TPO and anti-Tg autoantibodies were elevated, at fine needle aspiration biopsy a lymphocytic infiltrate, compatible with Hashimoto's thyroiditis, was present. We report here a rare case of Hashimoto's thyroiditis occurring both in the thyroid and in the ectopic thyroid tissue in the context of a benign cystic teratoma of the ovary. [ABSTRACT FROM AUTHOR]

Mature teratoma of adrenal gland is a rare entity. Neurocytoma is a low grade neuronal tumor even rarely seen among central nervous system tumors. Nervous system tumors arising in teratomas are frequently originated from glial or primitive neuroectodermal cells. Here we report a neurocytoma arising in mature cystic teratoma in the right adrenal gland of an 8 years old boy. Histological examination revealed a tumor composed of solid sheets in fibrillar basis with small uniform cells in the neuroglial tissue in teratoma. This is only the second case demonstrating a neurocytoma arising in a mature cystic teratoma in the literature. [ABSTRACT FROM AUTHOR]

Atypical teratoid/rhabdoid tumours (AT/RT) are aggressive neoplasms of the central nervous system occurring mainly in the paediatric population. We reported a 32-year-old male patient who was admitted in emergency in unconscious state. The neoplasm was localised in the left frontal region and was totally excised. The histological and immunohistochemical report revealed AT/RT. This unusual presentation underlines the necessity of considering this devastating neoplasm in the differential diagnosis of malignant brain tumours of adults. [ABSTRACT FROM AUTHOR]

In childhood mature cystic teratomas are the most common type of ovarian germ cell tumors. Tumors of neuroepithelial origin are extremely rare in mature teratomas. To the authors' knowledge, this is the first case report oligodendroglioma arising in a mature cystic ovarian teratoma in children. A 13-year-old girl presented with a history of pelvic pain for 2 months. An ultrasound examination showed a monolateral multicystic, calcific ovarian mass, measuring approximately 6 × 5 cm, arising in the left over and adnexia, suggesting a teratoma. An exploratorative laparotomy and ooferectomy were performed. On histopatological examination, various samples from cystic areas had mature tissues from all 3 germ cell layers, including skin, bone, bronchial structures, and cerebellum. Sections from solid areas showed uniform population of monotonous, rounded cells with indistinct cytoplasm and having perinuclear halo (fried-egg appearance) on a fibrillary, neuropilic background. Microcalcifications as calcospherites were noted in the stroma. Based on the typical morphological features, the cased was diagnosed as mature cystic teratoma with low-grade oligodendroglioma. To the authors' knowledge, there are a few reports in the literature of an oligodendroglioma arising in an ovarian teratoma in adults and this presented patient is the first case in childhood.

Background aims. Heart failure therapy with human embryonic stem cell (hESC)-derived cardiomyocytes (hCM) has been limited by the low rate of spontaneous hCM differentiation. As others have shown that p38 mitogen-activated protein kinase (p38MAPK) directs neurogenesis from mouse embryonic stem cells, we investigated whether the p38MAPK inhibitor, SB203580, might influence hCM differentiation. Methods. We treated differentiating hESC with SB203580 at specific time-points, and used flow cytometry, immunocytochemistry, quantitative real-time (RT)-polymerase chain reaction (PCR), teratoma formation and transmission electron microscopy to evaluate cardiomyocyte formation. Results. We observed that the addition of inhibitor resulted in 2.1-fold enrichment of spontaneously beating human embryoid bodies (hEB) at 21 days of differentiation, and that 25% of treated cells expressed cardiac-specific α-myosin heavy chain. This effect was dependent on the stage of differentiation at which the inhibitor was introduced. Immunostaining and teratoma formation assays demonstrated that the inhibitor did not affect hESC pluripotency; however, treated hESC gave rise to hCM exhibiting increased expression of sarcomeric proteins, including cardiac troponin T, myosin light chain and α-myosin heavy chain. This was consistent with significantly increased numbers of myofibrillar bundles and the appearance of nascent Z-bodies at earlier time-points in treated hCM. Treated hEB also demonstrated a normal karyotype by array comparative genomic hybridization and viability in vivo following injection into mouse myocardium. Conclusions. These studies demonstrate that p38MAPK inhibition accelerates directed hCM differentiation from hESC, and that this effect is developmental stage-specific. The use of this inhibitor should improve our ability to generate hESC-derived hCM for cell-based therapy. [ABSTRACT FROM AUTHOR]

Background: The authors report the experience at the Children's Hospital Los Angeles with brain tumors diagnosed before 6 months of age, describing the characteristics of the patients, their tumors, treatment strategies, and prognostic factors. Methods: Thirty-three children who were identified between 1979 and 2005 were included. Twelve were female (36%). There were 11 gliomas, 9 choroid plexus tumors, 8 medulloblastomas and supratentorial primitive neuroectodermal tumors (PNET), 2 atypical teratoid/rhabdoid tumors (ATRT), and 1 each of ependymoma, craniopharyngioma, and immature teratoma. Locations of primary tumors included 21 supratentorial (64%) and 7 posterior fossa, and 5 tumors involved both compartments. The treatment strategies included 5 patients with biopsy only, 18 less than gross total resections (

An unusual case of a carcinoid tumour in a lumbar extradural teratoma presenting as tethered cord syndrome and spina bifida without carcinoid syndrome in a 51-year-old woman is reported. These entities existing simultaneously in the same region are extremely rare and this suggests they have a common origin. [ABSTRACT FROM AUTHOR]

We present the case of a Middle Eastern child, diagnosed and treated at 8 months of age for a hepatic neuroblastoma. After surgical removal of a 7 cm mass of the left liver lobe at our institution when the child was 15 months of age, the tumor was reclassified as a teratoid hepatoblastoma. The tumor was composed of fetal and embryonal hepatic tissue, undifferentiated tissue, and a teratoid background of loose mesenchymal tissue containing osteoid, squamous, and mucinous epithelium. We speculate on the histogenesis of teratoid hepatoblastoma and discuss its association with chemotherapy. [ABSTRACT FROM AUTHOR]

Background Current efforts to direct differentiation of human embryonic stem cells (hESC) into a particular cell lineage usually lead to a heterogeneous cell population with only a fraction of the desired cell type present. We show the generation of an essentially pure population of human cardiomyocytes from hESC using lineage selection. Methods A construct comprising the murine α-myosin heavy chain (α-MHC) promoter driving the neomycin-resistance gene was introduced into hES3 cells to generate stable transgenic lines. Transgenic hESC lines were differentiated into cardiomyocytes and subjected to G418 selection. Both G418-selected and non-selected cardiomyocytes were characterized by immunocytochemistry and reverse transcriptase-polymerase chain reaction (RT-PCR) analysis. The teratoma-forming potential of differentiated cells was assessed by injection of about 2 million cells into the hind limb muscle of SCID mice. Results After cardiac differentiation and antibiotic selection in a suspension culture process, more than 99% of the transgenic cells showed immunoreactivity to α-MHC and α-actinin; this enrichment efficiency was observed for independent transgenic cell lines. Quantitative RT-PCR analysis revealed high levels of enrichment for cardiac-specific messages in the selected population. Importantly, injection of selected cells into six SCID mice resulted in no apparent teratoma formation, in contrast to differentiated but non-selected controls. Discussion Our results represent a significant step toward scalable production of pure human cardiomyocytes from stable, expandable hESC lines that will facilitate the development of cell therapies, safety pharmacology and drug discovery.

A 14-year old girl was diagnosed as suffering from an immature teratoma. As removal of the teratoma was technically unfeasible, the patient was started on interferon α2β, 3 MU/day, 5 days per week. On this therapy, the growth of the teratoma was stopped and the patient has been well for the past 50 months. She continues to be treated with interferon α2β, with almost no side effects and no restrictions of her everyday activities, with a good quality of life. She is able to attend school regularly, travels abroad frequently, and participates fully in everyday activities normal for her age and social conditions. Her Karnofsky performance status is 100. This case demonstrates the efficacy of interferon α2β therapy in certain instances of growing teratoma syndrome, even when the tumorous mass is initially quite large. [ABSTRACT FROM AUTHOR]

In Martin Stanton's 1990 monograph Sandor Ferenczi: Reconsidering Active Intervention, one of six exegetical chapters was titled "Teratoma", using Ferenczi's own word for malformations of (psychic) development. Since then, there has been a tendency in the larger Ferenczi literature to use "teratoma" as a metaphor, leading to the creation of many odd readings and contexts for this very specific, medical, anatomic term. When Stanton becomes expansive in viewing the teratoma as a "transitional object" which "negotiates a relationship between the growth of ideal-ego ideas in oneself and the outside 'influence' of inner systems of thought" (p. 176), he is entering the play-space that opened between Ferenczi and Groddeck during the 20s as Ferenczi's relationship with Freud became increasingly constricted. What this misses is that Ferenczi was a physician, as was Groddeck. For all their fanciful explorations of mind and body relatedness, for both Ferenczi and Groddeck there would be a shared background of certain basic terminology. In that medical terminology, "teratoma" refers to variable numbers of primordial germ cells in the embryo, which in the course of development become displaced, sequestered and grotesquely overgrown; they can never become the tissues they were meant to be. Their potential is forever squandered. "Monsters" they may be; "doubles" they may seem; but they are utterly non-viable. In his metaphorical application of the term "teratoma" to the natural history of (psychic) trauma, Ferenczi proposes a biological and psychological isomorphism that is both clinically illuminating and intuitively prophetic of the course of treatment of trauma, which he was discovering. Clinical and literary material are used to explore the gap between the anatomic teratoma and the psychic teratoma. [ABSTRACT FROM AUTHOR]

Spinal teratomas are rare intradural spinal tumours, commonly of benign histological profile. The main treatment remains surgical excision which often is incomplete as the tumour is frequently intimately related to surrounding nerve roots and adjacent spinal cord. The value of adjuvant treatment in the form of radiotherapy has not been clearly identified. We report two patients with spinal teratomas in the lower thoracic and conus region, who were treated with surgical excision and did not receive radiotherapy. One of the tumours recurred at 38 months following surgical excision and required a second operation.We review in addition another 20 patients reported in the literature with such tumours.With a mean follow-up of 25 months a local recurrence rate of 10% was observed, the same in both total and subtotal excision groups. No deaths were reported. Analysis of cumulative survival from surgery to treatment failure demonstrated that recurrence occurs late, verifying a slow biological progression of this tumour type. Although no reliable information of the effect of radiotherapy can be obtained, it is difficult to see how radiotherapy could have an impact on such a slow growing tumour. Initial treatment of choice remains surgical excision. If the teratoma shows any malignant histological features or germ cell elements radiotherapy should be employed after surgical excision, even if apparently totally excised. In the presence of benign histology it would seem appropriate to avoid radiotherapy after initial surgery. In case of tumour recurrence or progression to explore the possibility of further surgery first, before considering radiotherapy which even then may have doubtful efficacy. [ABSTRACT FROM AUTHOR]

Introduction: Orbital teratoma is a known cause of proptosis in neonates but it is rare in adults. Case report: An adult female presented with primary orbital teratoma with a well formed tooth inside the multicystic mass. Anterior orbitotomy with cyst excision was done with retrieval of a canine tooth. Comment: This report documents a unique case of orbital teratoma presenting in an adult with well formed canine tooth inside. Microcornea, corectopia and cataract were other distinctive coexisting features of our case. [ABSTRACT FROM AUTHOR]

Purpose: To describe the clinicopathologic features and management of an unusual case of orbital teratoma. Methods: A 7-year-old girl presented with a history of an orbital mass since birth. CT scan showed a large mass lesion involving the right orbit, with absence of the eyeball. An ectopic tooth was identified within the tumor. Lid-sparing exenteration surgery was performed. Results: Histopathologic examination of the excised mass showed presence of elements from all three germ layers, consistent with a diagnosis of mature orbital teratoma. Normal ocular structures were not identified on histopathology. At one year follow-up, there was no tumor recurrence. Conclusion: We report an extremely rare and interesting case of a mature orbital teratoma, which was associated with primary anophthalmos and an ectopic tooth. [ABSTRACT FROM AUTHOR]
