Its course can be complicated by metastases to distant sites such as the lung brain liver kidney and vagina. The therapeutic approach of this condition includes both surgical intervention and chemotherapy. The prognosis depends on many prognostic factors that determine the stage of the disease.

Accordingly she received chemotherapy as primary treatment but unfortunately developed massive bleeding after the first course of chemotherapy was operated in an attempt to control bleeding but finally succumbed. Conclusion This case demonstrates that GTN while usually curable can be a deadly disease requiring improved diagnostic treatment modalities and chemotherapeutic agents. The gynaecologist should be aware of all possible metastatic sites of GTN and the patient immediately referred to a specialist center for further assessment and treatment.
