Spontaneous massive hemoperitoneum in a reproductive-aged woman is usually associated with ectopic pregnancy. An unusual cause of intraperitoneal hemorrhage is presented: spontaneous rupture of hepatic
metastases
from unsuspected
choriocarcinoma
in a 29-year-old woman 4 weeks postpartum. Although
choriocarcinoma
is known to have the potential for subsequent hemorrhage of secondary sites, massive hemoperitoneum due to rupture of hepatic
metastases
is rare. In this case report, the presentation, prognosis groups, and treatment modalities are presented.

Seventy-three patients with metastatic high-risk gestational trophoblastic disease were treated with methotrexate, actinomycin D, and cyclophosphamide chemotherapy at the Brewer Trophoblastic Disease Center between 1968 and 1982. Forty-six patients were treated primarily with methotrexate, actinomycin D, and cyclophosphamide because of the presence of one or more high-risk factors. Twenty-seven additional patients who had not responded to initial single-agent chemotherapy with methotrexate and/or actinomycin D were subsequently treated with methotrexate, actinomycin D, and cyclophosphamide. Adjuvant surgery and radiotherapy were used in selected patients. The overall cure rate was 51% (37 of 73): 63% (29 of 46) for primary treatment and 30% (eight of 27) for secondary treatment (P less than .01). Several factors that influenced response to primary treatment with methotrexate, actinomycin D, and cyclophosphamide chemotherapy were determined: 1) clinicopathologic diagnosis of
choriocarcinoma
versus invasive mole (59 versus 100%), 2)
metastases
to sites other than the lung and/or vagina (44 versus 74%), 3) antecedent term gestation compared with hydatidiform mole or abortion (50 versus 75%), and 4) presence of three or more high-risk factors (27 versus 74%). There were no significant differences in cure rates during the course of the study period.

Placental site trophoblastic tumor is a rare variant of trophoblastic disease. The malignant form of this disease with metastasis and death is even more infrequent, as is evident from only five cases in the literature. A 30-year-old black woman who died from this disease is presented. Patients with
metastases
are at extremely high risk with no reported survivors and must be treated aggressively with chemotherapy and cytoreductive surgery. This type of trophoblastic tumor apparently exhibits a different biologic behavior as compared with
choriocarcinoma
.

Germ cell tumours form an important group of gonadal neoplasms and are also found in a number of extragonadal sites like the mediastinum, para-pineal and sacrococcygeal regions and retroperitoneum. Although there are considerable differences between germ cell tumours occurring in different anatomical locations they exhibit a remarkable homology, and are considered as a group. In this review germ cell tumours are discussed as a group emphasizing some of the recent developments in this field. In the testis germ cell tumours form the most common group of neoplasms comprising 90% of all testicular tumours and 99% of them are malignant. In the ovary germ cell tumours comprise approximately 20% of ovarian neoplasms, and more than 90% are mature cystic teratomas and are benign. Malignant testicular neoplasms are 10 times more common than their ovarian and 20 times more common than their extragonadal counterparts. Malignant germ cell tumours have a specific age incidence and occur mainly in children and young adults. Due to this they represent one of the most important groups of neoplasms in this age group. Testicular germ cell tumours show marked racial and geographical differences occurring much more frequently in Western Europe, especially in Scandinavia, as compared with Southern and Eastern Europe. They are rare in Africa and are very uncommon in Blacks as compared to Whites. These remarkable differences are not observed in ovarian or extragonadal germ cell tumours. It is now accepted that histogenetically all the tumours in this group are of germ cell origin, and that germ cell tumours are capable of somatic (embryonal) and extra-embryonal differentiation (fig. 1). The occurrence of extragonadal germ cell tumours in anatomical locations in the midline of the body is explained on the basis of migration of the primitive germ cells during embryonic life from the wall of the yolk sac to the primitive gonad. An all embracing classification of germ cell neoplasms based on the WHO classifications of ovarian and testicular tumours is presented. The importance of careful and thorough examination of germ cell tumours is emphasized, especially in view of the recent advances in the therapy of malignant germ cell neoplasms. The value of tumour markers like alphafoetoprotein (AFP) and human chorionic gonadotropin (HCG) produced by endodermal sinus tumour (EST) and some embryonal carcinomas and
choriocarcinoma
and syncytiotrophoblastic giant cells respectively in diagnosis, monitoring the progress of the disease, and the efficacy of therapy, as well, as for early detection of
metastases
and recurrences, is strongly emphasized.(ABSTRACT TRUNCATED AT 400 WORDS)

Between 1962 and 1983 a total of 26 patients with malignant trophoblastic disease were diagnosed in northern Finland. The incidence of this disease was 1:21,000 pregnancies. Eight patients had
choriocarcinoma
and 18 an invasive mole. Clinically, 15 patients belonged to the nonmetastatic and 11 to the metastatic group. Of the latter, 4 patients belonged to the low-and 7 to the high-risk categories. During the first years of the study period, cytotoxic chemotherapy, mostly single-drug therapy, was often complemented with adjunctive surgery and/or irradiation. During recent years, single- or multidrug chemotherapy was supplemented with surgery in only one case with chemotherapy-resistant pulmonary
metastases
. All 26 patients are alive and disease-free, and after therapy 6 of them have given birth to 1-3 children. Our results suggest that malignant trophoblastic diseases can be successfully treated also in small centers of gynecologic oncology with up-to-date knowledge of the principles of modern cytotoxic chemotherapy.

A 10-year-old girl had a primary
choriocarcinoma
of the posterior third ventricle. Craniotomy a few hours before death did not yield any tumor tissue. At autopsy, an extensively hemorrhagic tumor abutted the pineal gland. Immunostains were positive for beta-human chorionic gonadotropin (beta-HCG) but were negative for alpha-fetoprotein and carcinoembryonic antigen. The presence of beta-HCG in serum or cerebrospinal fluid may be used as a diagnostic marker and monitor of therapy. HCG is, however, not a unique marker for trophoblastic neoplasms, as a significant number of intracranial germinomas contain cells that are beta-HCG positive. Because of the rarity of primary extragenital choriocarcinomas and the much more common occurrence of
metastases
of genital choriocarcinomas, it is doubtful whether any investigation less than detailed autopsy can prove the extragenital origin of the tumor.

The unique curability of gestational trophoblastic tumors may in part be attributable to a host immunologic response. The occurrence of rapidly progressive and fatal
choriocarcinoma
may be favored by histocompatibility between patients and their partners. However, histocompatibility is not a prerequisite for the development and persistence of gestational
choriocarcinoma
. The expression of HLA by
choriocarcinoma
cells in culture is enhanced following incubation with gamma-interferon and this may be of both biologic and clinical significance. Complete molar pregnancy is a complete allograft because all molar chromosomes are of paternal origin. Patients with complete mole are sensitized to paternal HLA antigen which is expressed in molar tissue. Other polymorphic antigen systems including trophoblast-leukocyte common antigens and placental-type alkaline phosphatase are also expressed in molar tissue. We have studied the immunopathology of the molar implantation site to investigate possible humoral and cellular immune responses. The relationships among normal placenta, complete mole and
choriocarcinoma
are not clearly understood. The pattern of expression of oncofetal antigens in these three gestational tissues may be used to assess trophoblastic differentiation. In studies to date, molar trophoblast has the same pattern of expression of oncofetal antigens as normal placental trophoblast. We will review recent advances in our understanding of the immunobiology of gestational trophoblastic disease and suggest new directions for further research.

There seems to be no higher incidence of primary brain tumor in pregnancy. There are no extracranial tumors that are likely to
metastasize
that are uniquely related to the specific pregnancy.
Choriocarcinoma
during the index pregnancy is rare. Although pregnancy-related
choriocarcinoma
has a high propensity for brain metastasis, it is in the postpartum period or later that such tumors and their
metastases
present. The fetus seems to be spared from any complications resulting from maternal tumor, provided that it is safely delivered. There is a rich literature on the immunology and steroid receptor pharmacology of brain tumor but alterations in immunity or in receptor sites seem to have little impact on the incidence of tumors during pregnancy. There may be modification of the behavior of brain tumors by pregnancy and hence possibly by steroid hormones. The principle governing management of the mother is primarily common sense. As the ability to manage brain tumors in general improves, the necessity of interfering with either the pregnancy or mode of delivery evaporates.

Two examples of intraplacental
choriocarcinoma
are described. Both were small and had arisen in otherwise normal third trimester placentas. The covering mantle of many of the villi adjacent to the choriocarcinomas was formed, either focally or wholly, of neoplastic trophoblastic tissue: it is only at this stage of the development of a
choriocarcinoma
that villous structures are present, and a study of these cases adds further evidence for an origin of
choriocarcinoma
from villous trophoblast. Intraplacental choriocarcinomas can give rise to both maternal and fetal
metastases
during pregnancy, and it is suggested that such lesions also serve as an origin for those choriocarcinomas which follow a term pregnancy.

We report a case of pure
choriocarcinoma
of the left testis with multiple pulmonary and cerebellar
metastases
. A 25-year-old male was referred to our clinic because of painless swelling of the left scrotal content and multiple nodules shown in the chest X-ray. At hospitalization, the examination also revealed cerebellar metastasis. With left high orchiectomy, the lesion was confirmed to be pure
choriocarcinoma
. In spite of several treatments including surgical removal of metastatic brain tumor and combination chemotherapy, he died on the 79th hospital day. Pure choriocarcinoma of the testis is an uncommon disease. Only 46 cases have been reported in the literature before 1987.
