Choriocarcinoma is a unique neoplasm that can occur after a pregnancy, as a component of germ cell tumors, or follow the trophoblastic differentiation of neoplastic somatic cells that completely lose their normal phenotype and produce hCG. Gestational Choriocarcinoma (GC) and Nongestational Choriocarcinoma (NGC) are pathologically and morphologically similar, but differ in genetic origin, immun...

Case reports are presented on 2 patients to show the importance of following up apparently false positive results of pregnancy tests. In case 1, a 25-year-old woman was admitted to the hospital with severe breathlessness in September 1987. After she had stopped using oral contraceptives (OCs) in 1985 her periods were irregular and on 4 occasions the results of pregnancy tests bought over the ...

Background: The most common clinical types of gestational trophoblastic neoplasia are invasive hydatidiform mole and choriocarcinoma, which can be diagnosed without pathology, cured by chemotherapy. Epithelial tumor, a rare type neoplasia, does not exhibit precise manifestations upon auxiliary examinations. Therefore, since epithelial tumors prone to misdiagnoses missed diagnoses, their diagnos...

Infantile choriocarcinoma is a highly malignant rare germ cell tumor that arises from the placenta. Simultaneous intraplacental choriocarcinoma involving both mother and infant is extremely rare. Cutaneous metastasis in infantile choriocarcinoma is even rarer with only a few case reports available. Here we describe a case of a female neonate who presented to the ED with a rapidly growing and bl...

Introduction: Gestational trophoblastic disease (GTD) includes hydatiform mole, choriocarcinoma, placental site tumor, and epithelial tumor. Also, molar pregnancy can happen as an ectopic pregnancy. The coincidence of these complicated pregnancies seems to occur extremely rarely. Case presentation: Here, we presented a 26-year-old woman, nulli gravida with the first presentation intrauterine co...

Choriocarcinoma is an extremely rare pathology among breast malignancies. It is introduced by two distinct terms in the literatures: breast cancer with choriocarcinomatous features and metastatic choriocarcinoma to the breast. In this case report, the history, physical examination, laboratory findings, imaging studies, and pathological findings of breast choriocarcinoma in a 41-year-old woman a...

Intracerebral hemorrhage can occur due to primary and metastatic intracranial neoplasm. In half of the cases it may be the first manifestation of the tumor. It is also known that metastatic tumors bleed more than the primary CNS tumor [1]. Metastatic choriocarcinoma is a rare but an important cause of intra cerebral hemorrhage in female patients in reproductive age group. Choriocarcinoma (gesta...

Choriocarcinoma and placental site trophoblastic tumor (PSTT) are rare varieties of gestational trophoblastic disease (GTD). PSTT alone constitutes about 1-2% of all trophoblastic tumors, which presents at early reproductive age and the serum beta-hCG level is much lower than choriocarcinoma. This tumor usually invades the myometrium and its depth of penetration is a prognostic factor. The firs...

INTRODUCTION Gestational choriocarcinoma occurs in 1 in 40,000 pregnancies. Of all forms of gestational choriocarcinoma, placental choriocarcinoma is the most rare. Maternal choriocarcinoma is usually diagnosed in symptomatic patients with metastases. The incidental finding of a choriocarcinoma confined to the placenta with no evidence of dissemination to the mother, or infant is the least comm...
