“…Nevertheless according to Smith, rates for immature teratomas are higher for Asian/Pacific Islanders and Hispanics than Caucasians [12,13]. More specifically, immature formations of teratomas are classified into three categories: firstly, lesions that include immature ectodermic tissue and neuroectodermal epithel in rosettes and tubules, secondly, masses that contain immature mesenchyme with immature cartilage, immature fat, osteoids and rhabdomyoblasts and finally immature endodermal tissue as well as hepatic tissue, intestinal type epithel with basal vacuolization and embryonic renal tissue [1]. Macroscopically immature teratomas are larger (14-25 cm) than cystic teratomas (max diameter: 7 cm approximately).…”

“…Ιt should be noticed that they consist almost the half of the malignant tumors observed in infancy [10]. Rarely, they might originate from brain, retroperitoneum, pericardium and organs like thyroid, liver, parotid gland, breast, stomach, bladder and esophagus [1,2]. Based on APO reports, teratomas are discriminated in benign mature and malignant immature pathologies.…”

“…The word teratoma derives from the Greek word "teras" (monster) [2]. Teratomas are mainly identified in young women, <45 yrs, arising from the ovary [1]. Ιt should be noticed that they consist almost the half of the malignant tumors observed in infancy [10].…”

“…The ovarian teratomas are divided into mature teratomas, immature teratomas and monodermal teratomas (like struma ovarii, carcinoid tumors, and neural tumors). They represent the largest part of germ cells neoplasms [1,2]. Mature cystic teratomas (dermoid cysts) constitute the majority of ovarian germ cell tumors accounting for 20% of all ovarian neoplasms [3].…”

with specific tumor markers .So, tumor markers Ca 15-3, Ca19-9, Ca 125, and CEA were fluctuated in normal ranges. Serum levels of alphafetoprotein (a-FP) were significantly elevated reaching the plateau of 392 iu/ ml (normal ranges: <9.5 iu/ml), supporting the sonographically evoked opinion of underlying malignancy. Except that AST (62 IU/L), ALT (73 IU/L) and LDH (309 IU/L) were mildly increased.Because of the young profile of the patient, MRI of upper and lower abdomen has been also performed; similarly to ultrasonographic report, MRI noticed the presence of excessive ascites; it also described a heterogeneous right ovarian mass of 88 × 81 × 100 mm presenting cystic, solid and hemorrhagic contents, fixed to the broad ligament of the uterus. It also revealed 2 thin walled cysts of 4, 3 cm and 2, 4 cm in the left ovary without solid parts. Intraperitoneal tissue in the region of upper abdomen was described, implying the possibility of underlying peritoneal carcinomatosis. The liver, the biliary system, the spleen, the pancreas and the adrenals were normal. MRI didn't reveal enlarged paraaortic, mesenteric, iliac or inguinal lymph nodes (Figure 2). Chest X-ray and ultrasonographically breast examination were normal. Initially, ascites suction was realized in order to alleviate from pressing symptoms. In the operation theater under general anesthesia, laparoscopy was performed with the technique of the four ports for better abdominal exploration in the overweight patient; 4 to 5 liters of ascites were aspirated for cytological examination. The organs of the upper abdomen were normal, without implantations in the peritoneum or omental disease. The uterus and the left adnexa were normal but a mass 10-12 cm of right ovary characterized by abnormal surface was revealed. So exploratory laparotomy followed with vertical incision .Then the cystic lesion was removed and sent for frozen section. The rapid biopsy was positive for
