Introduction: Retroperitoneum is the third most common extragonadal site for occurrence of teratoma in children, after sacrococcygeal region and gonadal sites. Although many authors have previously reported laparoscopic removal of benign retroperitoneal teratoma in adults, the experience in pediatric setting is extremely limited. Material and methods: We report our experience with laparoscopic ...

Gastric teratomas are very rare tumours in children. They usually present with a palpable mass in the upper abdomen. We report a case of gastric teratoma in one and half month old male infant who presented with a palpable mass in abdomen, extending from epigastrium to the pelvis. Ultrasound of abdomen revealed a huge mass with solid and cystic components. CT scan delineated calcifications in th...

Composing of less than 1% of all ovarian cancers, immature teratoma is a malignancy that mainly affects the young. In this report, we present the first case of pathologic fracture of the proximal femur resulting from metastatic bone tumor of ovarian immature teratoma. A 33-year-old Korean female was diagnosed as immature teratoma of stage Ia and grade 3. Eleven months following initial surgery,...

Intrathoracic teratoma is mainly found in the mediastinum. Primary intrapulmonary teratoma is very rare. A 24 year-old female presented with a 2-month history of intermittent episodes of cough and haemoptysis. Contrast enhanced computed tomography (CT) examination of chest revealed a mass in the left lingular lobe with evidence of fat and surrounding peripheral translucency. A presumptive diagn...

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 eightee...

The endogenous levels of auxin and cytokinin in teratoma and unorganized tobacco (Nicotiana tabacum L. var Wisconsin #38) crown gall tumor tissues were determined. Teratoma tissues contain levels of auxin and cytokinin favorable for shoot formation, whereas unorganized tumors contain levels of auxin that suppress shoot formation. This conclusion is based upon the observation that when levels of...

Mature ovarian cystic teratomas are common benign ovarian neoplasm derived from germ cells. With increasing availability of ultrasound services even in developing countries, the diagnosis of benign ovarian tumour is made earlier and the size of the ovarian tumour at diagnosis is relatively small. It is unusual to find an ovarian cystic teratoma larger than 10 cm. We report a huge mature ovarian...

A rare case of intraventricular germinoma in the third ventricle, which occurred 30 months after total removal of mature teratoma on the same location in a 29- yr-old man is presented. Recurrence is supposed to represent an acceleration of localized dysplastic processes of totipotent germ cells present in the midline neuraxis or a growth of unidentified microscopic residue of germinoma componen...

Benign solid teratomas within the fallopian tube are rare. The incidence of this kind of benign solid teratoma of the fallopian tube associated with intrauterine leiomyomas is extremely low and may complicate the clinical manifestations. Here, we report a 40-year-old female with periodic lower abdominal pain and hypermenorrhea who was found to have 3 nodules within the uterine myometrium and le...

Mature cystic teratoma is the most common germ cell tumor of ovary comprising 10-20% of all ovarian tumors (1). Mature cystic teratoma is generally a benign tumor, however cases of malignant transformation occurs in 1-2% of cases (2). Preoperative diagnosis of malignant transformation is difficult because of the lack of specific symptoms and signs to suggest malignancy.The various types of mali...
