Oral mature teratoma containing epididymal tissue in a female neonate

An Unusual Lesion of Epignathus with Duplicate Tongue and Ranula in a Neonate

We report a rare case of epignathus (oropharyngeal teratoma) in a neonate, who presented with a midline mass covered with skin and multiple hairs protruding from the Palate and associated with bifid tongue and ranula. With the characteristic presentation, diagnosis of oro/oropharyngeal teratoma was made and a massive internet search revealed very few reported cases of "epignathus". It is unfortunate that the survival of such neonates is only moderate. Prenatal scans and follow up in an institution can prepare the multidisciplinary team to save the child. EXIT procedure to excise the mass or secure the airway, with future repair of the palate is the treatment option available. This case report emphasizes the rare clinical presentation of the disease and the prenatal diagnosis of such a condition can help in prompt decision making and management.

Cleft palate associated with cervico-facial teratoma: report of two cases and review of the literature

We report two original cases of association of cleft palate and lateral cervico-facial teratoma. We discuss the embryological explanation. The first child presented a cleft palate associated with two cervico-facial localisations of teratoma. The other had Pierre Robin sequence associated with lateropharyngeal teratoma with an extra sub maxillary localisation. Most reported cases were of midline teratomas, leading different authors to advance a mechanical origin to the cleft. Our cases are different: we could hardly find reported cases of associate lateral tumours and cleft palate, which would suggest two different embryologic mechanisms, or at least a combination of more complicated phenomenons.

An unusual case of Cat-Eye syndrome phenotype and extragonadal mature teratoma: review of the literature

BACKGROUND Cat-Eye syndrome (CES) with teratoma has not been previously reported. We present the clinical and molecular findings of a 9-month-old girl with features of CES and also a palpable midline neck mass proved to be an extragonadal mature teratoma, additionally characterized by array comparative genomic hybridization (aCGH). RESULTS High resolution oligonucleotide-based aCGH confirmed that the supernumerary marker chromosome (SMC) derived from chromosome 22, as was indicated by molecular cytogenetic analysis with fluorescence in situ hybridization (FISH). Additionally, aCGH clarified the size, breakpoints, and gene content of the duplication (dup 22q11.1q11.21; size:1.6 Mb; breakpoints: 15,438,946-17,041,773; hg18). The teratoma tissue was also tested with aCGH, in which the CES duplication was not found, but the analysis revealed three aberrations: del Xp22.3 (108,864-2788,689; 2.7 Mb hg18), dup Yp11.2 (6688,491-7340,982; 0.65 Mb, hg18), and dup Yq11.2q11.23 (12,570,853-27,177,133; 14.61 Mb, hg18). These results indicated 46 XY (male) karyotype of the teratoma tissue, making this the second report of mature extragonadal teratoma in a female neonate, probably deriving from an included dizygotic twin of opposite sex (fetus in fetu). CONCLUSIONS Our findings extend the phenotypic spectrum of CES syndrome, a disorder with clinical variability, pointing out specific dosage-sensitive genes that might contribute to specific phenotypic features.

Bipartite anterior extraperitoneal teratoma: evidence for the embryological origins of teratomas?

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 “missed target” theory of embryology.

A large teratoma of the hard palate: a case report

Congenital teratoma is a rare malformation, and few papers have been published about it. We present a large teratoma that arose from the hard palate in a neonate. The obstructive mass caused maternal polyhydramnios and was identified prenatally by ultrasonography. The mother went into labour at 35 week's gestation at home. The child was in respiratory distress as a result of airway obstruction, and a tracheostomy was done when she was 4hours old. She also had major cardiac abnormalities. The palatal mass was removed successfully at 4 weeks of age. The typical components of a teratoma were identified including immature neural glial tissue.

The place of fine-needle aspiration in the preoperative diagnosis of the congenital sublingual teratoid cyst

The term "teratoid cyst" was first used by Meyer in his classification of dysontogenetic cysts of the cervicofacial region, which was based on the type of germinative layers included in the cyst wall. Sublingual location of a dermoid cyst is not common, with an incidence of 1.6%. The teratoid cyst is the least common, accounting for 1.8% of sublingual dermoid cysts, and such lesions are extremely rare in infancy. In our case, a 7-mo-old male infant was referred with a sublingual mass. Ultrasonography yielded a cystic mass with internal echoes but no specific diagnosis. The smears obtained from fine-needle aspiration (FNA) displayed sheets of large, benign-appearing, anucleated and nucleated squamous cells. There were a number of neutrophils, which had no significant importance. No atypical cells were observed. According to the clinical picture and FNA findings, it appeared to be a cystic structure of keratogenous origin and could have been any type of dermoid cyst. The cyst was excised completely by the oral approach. On histopathological examination, the presence of skin appendages along with mature cartilage and respiratory epithelium confirmed the final diagnosis of a teratoid cyst. In conclusion, although FNA is not comparable with computed tomography (CT) and magnetic resonance imaging (MRI), it might be valuable for the diagnosis of lesions occurring in this anatomical location. It is safe, cost-effective, and reliable. FNA is not only able to help selecting the most appropriate surgical method, but also be used as a therapeutic modality in some emergencies or during surgery.
