Invasive mole

Abstract

Invasive mole is an infrequent condition characterized by excessive trophoblastic proliferation and trophoblast penetration into the myometrium, without a tendency to metastatic dissemination. The purpose of the study is to present a case diagnosed with gestational trophoblastic neoplasia of the invasive mole type. The following complementary tests were performed: transabdominal echography, human chorionic gonadotropin beta subunit determinations, and endometrial biopsy by uterine curettage. The result was molar pregnancy. Upon admission the patient was administered systemic methotrexate 25 mg intramuscularly, as well as an intramuscular ampoule of folinic acid 15 mg daily, both during five days. Total abdominal hysterectomy without anexectomy was performed 20 days later. Clinical evolution was followed up on an outpatient basis. The following tests were also performed: chest radiography, pelvic ultrasonography, human chorionic gonadotropin beta dosage, complete blood count, clotting time, bleeding and evolutive glutamic-pyruvic transaminase. During management of the invasive mole, the combination of clinical and surgical treatments proved effective and was well assimilated by the patient.
