Teratoma of mediastinum is rare germ cell tumor. Anterior mediastinum is the most common extragonadal site. Benign mediastinal teratoma accounts for 60% of all mediastinal germ cell tumors. Benign mature teratoma has excellent prognosis after surgical excision. We present a case of 20-year-old woman diagnosed as benign mature teratoma which compressed main pulmonary trunk. The patient underwent...

It is rare to encounter benign forms of mature cystic teratoma in elderly women. has been reported that the risk malignant transformation doubled patients with aged over 50 years. We a case 52-year-old woman large pelvic mass. The imaging and operative findings have described. diagnosis was confirmed on histopathology as teratoma.

Rabbit antisera to a mouse testicular teratoma, absorbed with normal mouse tissues, react by immunofluorescence with plasma membrane antigens of a variety of transplantable mouse tumor cells and transformed fibroblast cell lines including Clone 1D, SV-40-3T3, and 3T12. Trypsin treatment of cells of "normal" lines, 3T3 and FR-SV-3T3, uncovers reactivity on these as well. Early passage mouse embr...

Background: Teratoma is a tumor comprised of three germinal layers classified as mature or immature in most cases. Most solid teratomas are benign but may turn malignant; therefore, complete resection advised these They usually occur women. Primary rectal infrequent, and only few cases have been described the literature. Teratomas common cystic that rise ovary, testicle, retroperitoneum. can al...

Dermoid cyst (also called as ‘mature teratoma’) is a type of germ cell tumour. The word ‘teratoma’ derived from Greek work ‘teraton’ meaning monster. It was initially used by Virchow in 1863. term ‘dermoid cyst’ coined Leblanc 1831. majority dermoid cysts are unilateral with equal frequency both ovaries; moreover, bilateral tumours found approximately 10-12% cases and we presented two such ovary.

teratomas are emberyonal neoplasms derived from totipotential cells that contain tissue from at least two and more often three germ layers (ectoderm, enoderm and mesoderm) in the midline or paraxial location from brain to sacrococcygeal region. the primary objective of this study is to determine this rather common newborn and children teratomas in different areas of the body. the secondary obje...

Gastric teratoma is very rare tumor and usually presents in early infancy. An 8-year-old boy presented with a huge mass in abdomen extending from epigastrium to the pelvis. Ultrasound and CT scan of abdomen revealed a huge mass with solid and cystic components and internal calcifications. The preoperative diagnosis was a teratoma but not specifically gastric one. At operation, it was found to b...

While mature cystic teratoma of the ovary is the most common ovarian tumor in young women, immature teratoma is a very rare tumor, representing only 1% of all ovarian cancers. In the three cases presented here, young women who were suspected to have mature cystic teratoma, based on CT scan and MRI, were ultimately diagnosed with immature teratoma Ic (b) G1 after laparoscopic operation. They und...

Teratoma of the neck is a rare extra-gonadal teratoma. Although it can be seen in adult, most of the cases present in fetal life or early childhood. Grading and classification of teratoma is important for management and prognosis. Decision making between mature and immature teratoma is sometime challenging if it is not composed of extensive unusual neuroectodermal tissue component. We reported ...
