Hysteroscopy in gestational trophoblastic diseases.

Hysteroscopic evaluations were performed in eight women with gestational trophoblastic diseases. Seven of the eight patients had abnormal hysteroscopic findings and biopsies were obtained from the endometrium and adjacent myometrium. Five patients had histopathological proof of tumour. This preliminary report shows the feasibility of the method. The potential risks involved are discussed. A correct histopathological diagnosis in patients evaluated for gestational trophoblastic diseases may be useful in order to tailor the treatment.
