A 14 1/2-year old girl with menometrorrhagia followed by amenorrhea and abdominal pain had a pelvic resistance with limited mobility. Histology of a left ovarian tumour showed gonadoblastoma turning to dysgerminoma and associated with choriocarcinoma (M-9073/1, M-9060/3, M-90101/3). Genuine ovarian tissue was hypoplastic on both sides. In the right ovary, there were additional thecalutein cysts. The patient's karyotype was 46 XX. She has been without any relapse 2 1/2 years after chemotherapy and actinotherapy.

The case of a 24-year-old woman with fever, abdominal pain and weight loss, is presented. Right ovarian dysgerminoma was diagnosed; group A blood, negative direct Coombs. The search for free serum antibodies was positive, with specificity: auto anti 1, anti P with activity at 37 degrees C. Hysterectomy, appendectomy, omentectomy and retroperitoneal ganglia biopsy, were performed; the latter one showed metastasis. Blood transfusions were given. Thirty days postoperative, the red cell polyagglutination had disappeared, as well as antibodies.

Over a five-year period, we treated 16 children ranging in age from 8 weeks to 16 years for ovarian masses. The most frequent clinical manifestation was abdominal pain and/or mass. Ultrasonography correctly localized the lesion and delineated its nature in nine of ten cases. Operation in 15 showed teratoma (six benign, two malignant), endodermal sinus tumor (two), dysgerminoma (two), follicular cyst (two), and leukemic ovarian infiltrate (one). Adnexal torsion was present in three. Three children had tumor metastases at initial operation. Resection of the tumor with conscious preservation of uninvolved pelvic structures was performed if possible. For unresectable tumor, debulking was undertaken. Multiagent chemotherapy was used for all malignant tumors. Survival was 94%. The proper therapy for ovarian lesions in children requires familiarity with the unique nature of these lesions, as well as consideration of future endocrine and reproductive function.

Malignant germ cell tumors are an uncommon type of ovarian cancer which account for fewer than 5% of the total in Western countries and 20% in Japan. In females younger than 20, they represent approximately two-thirds of malignant ovarian tumors. Immature teratoma, endodermal sinus tumor, dysgerminoma and mixed type account for the majority (more than 80%), while embryonal carcinoma and polyembryoma are very few. The age of the patients ranges from 6 to 69 years with a median of 16-20 years. Clinically, these tumors are characterized by rapid growth and extensive intraabdominal spread. The symptoms and signs range from 1 day to 6 months with a median of 4 weeks, and the patients usually present with abdominal pain, palpable mass, abdominal distention and vaginal bleeding, and a very few with amenorrhea and precocious puberty. The size of tumors varies from 7 cm to 40 cm with a median of 15-16 cm. The tumor is rarely bilateral (12-19%) and never so in cases of endodermal sinus tumor. Diagnosis depends mainly on age, abdominal symptoms, size and consistency of the tumor, and tumor markers AFP and hCG. Surgery is the first step of management followed by adjuvant therapy, which depends on the histologic type. Dysgerminoma is very sensitive to radiation while other germ cell tumors are not. A combination chemotherapy currently used is VAC or VBP. Both are highly effective. The VBP regimen seems to have a stronger cancerocidal effect, while the VAC regimen is less toxic. VAC produces excellent results in stage I, while VBP is more effective for advanced disease. Conservative surgery and a combination chemotherapy (VAC, VBP) are appropriate for young patients who desire to retain their fertility. Second-look laparotomy is still controversial. As long as AFP or hCG or both can be used to monitor the disease in patients positive for these sensitive and reliable markers, or in an early stage with complete resection, second-look laparotomy is not useful. Survival is associated with prognostic factors, i.e., histologic type, clinical staging operation, lymph node and residual tumor. Patients with endodermal sinus tumor or mixed type tumor had a poorer outcome. The survival rate was higher in patients with earlier disease (stage I or II) and those who underwent primary surgery. Metastasis to the lymph node is not related to prognosis. The presence and size of residual tumors after surgery were closely related to the prognosis.

Mixed germ cell tumours of the ovary are rare malignant neoplasms containing combinations of two or more types of germ cell elements. The aim of the study was to review biopsy examinations, medical records, treatment strategy, follow-up and outcome of all girls treated for mixed germ cell tumour of the ovary at the Department of Pediatric Oncology, University Hospital Motol during the period 1979-2002. Archival slides of all tumours were reviewed and tumours were classified according to the WHO system. The clinical data on surgical treatment, chemotherapy and radiotherapy used and follow-up information were obtained in all girls. The staging was reviewed retrospectively on the basis of surgical and pathological findings and results of imaging investigations, and it was outlined according to the most recent FIGO criteria and TNM classification. Sixteen girls with mixed germ cell tumour of the ovary, age range 3 years 11 months to 17 years 8 months (median 12 years) were treated. All girls presented with unilateral tumour of the ovary and all underwent surgery as an initial treatment. The most common presenting symptom was abdominal pain, occurring in ten patients. The original diagnosis of mixed histology was confirmed in all cases; in five cases the tumour contained three histologic components, in eleven cases the tumour consisted of two germ cell types. All tumours contained elements of yolk sac tumour, followed by immature teratoma, embryonal carcinoma, dysgerminoma and mature teratoma. At the time of diagnosis three patients had stage I disease, four patients stage II, seven stage III and two stage IV disease. All patients were treated with chemotherapy after surgery, predominantly with platinum-based regimens (PVB, BEP). Three patients treated initially with MAC (metothrexate, dactinomycin, cyclophosphamide) were diagnosed in the early eighties. In seven girls with advanced disease treated in the early years, radiotherapy was administered to the pelvis or whole abdomen. Overall survival and event-free survival were 80% and 81.3% respectively (median follow-up time 7.6 years). Three patients have died from the disease, two progressed on treatment (MAC), one girl relapsed three months after finishing therapy, no further therapy was administered. One girl underwent resection of tumour of her remaining ovary 24 months after original diagnosis. Histology showed mixed serous and mucinous cystadenoma. The latest examinations revealed that all other patients were in good health. Microscopic examination should be extensive and careful to find out all types of malignant germ cell elements. Platinum based chemotherapy is effective in the management of children and adolescents with mixed germ cell tumors of the ovary. Chemosensitivity of these tumours allows most girls to have conservative surgery with possible preservation of reproductive function.

Ovarian masses in the pediatric age group are rare, and malignancies are even less common. We reviewed our large single-center experience to determine the rate of malignancy and discuss management. We retrospectively reviewed the cases of ovarian masses in children in our institution over a 10-year period. Demographic and tumor-specific data were reviewed and analyzed, and a Student's unpaired t test was used where appropriate. A total of 49 children and adolescents with ovarian masses were found. The mean age at presentation was 13.3 years. Eight masses were malignant (16%) with malignant teratoma, dysgerminoma, and germ cell tumors found. These patients responded to chemotherapy, but there were three recurrences noted that responded to further therapy. Seventy-four per cent of the benign tumors were teratomas. The most common presentation was abdominal pain in 27 patients (55%) followed by an abdominal mass. Ultrasound and CT scans were the most common imaging studies with a mean mass size of 14.7 cm. A majority of the patients underwent a laparotomy with 12 per cent having a minimally invasive procedure. Only 37 per cent of the operations were performed by the pediatric surgeons. There were no deaths in this series after a follow up of over 6 years. Most ovarian masses in childhood are benign. Malignant lesions have favorable outcomes with chemotherapy, even with recurrent disease. Consideration for laparoscopic procedures should be given for the benign lesions.

A mare was referred for further evaluation of a mass found in the left caudal abdomen during a routine postpartum reproductive palpation. The mare was clinically normal with no history of health problems. Ultrasonographic examination of the mass confirmed its presence, but the origin of the mass could not be accurately determined. Routine haematology and serum biochemistry results were within normal limits. The mare was initially treated conservatively with antibiotics, but the mass continued to increase in size, so it was surgically excised. The mass involved the left ovary. The mare showed transient abdominal pain after surgery, but developed no other complications and was in foal 7 months later. On histology, the mass was diagnosed as a dysgerminoma, a rare ovarian tumour of germ cell origin.

A 35-year-old woman presented with abdominal pain and weight loss. Pelvic computed tomography showed a 15 cm mass in the left ovary. Grossly, the removed ovary was completely replaced by a solid tumor mass. On histological analysis (100 sections), the lesion showed the typical morphological features of dysgerminoma (20%) admixed with a major (80%) fibrosarcoma component. Tumors did not have well-demarcated boundaries with a close intermingling of both cell types. Despite surgery and combination chemotherapy, the disease progressed rapidly and the patient died of disease 18 months after diagnosis. Review of the literature showed that soft tissue sarcomas of several types may occasionally be associated with gonadal and extragonadal mixed germ-cell tumors or with spermatocytic seminoma of the testis. However, no previously published report of an ovarian fibrosarcoma associated with a pure dysgerminoma was found in the literature.

Dysgerminoma accounts for only 1-3% of ovarian cancers and about 30-40% of all ovarian germ cell malignant tumors. Literature states that about 2% of nonpregnant patients with dysgerminomas present with elevated serum or urine levels of human chorionic gonadotropin (hCG). Here, we report a 34 year-old multiparous woman presenting with an abdominal lump, ascites, and abdominal pain with elevated urinary and serum hCG levels. An abdominal ultrasound showed bilateral ovarian mass. An ultrasound-guided, transabdominal fine needle aspiration revealed dysgerminoma with syncytiotrophoblastic giant cells. Bilateral oophorectomy was done and the diagnosis was confirmed on histopathology.
