Metastasis of Testicular Choriocarcinoma in the Stomach, Complicated by the Development of Choriocarcinoma Syndrome

Abstract

Choriocarcinoma (CC) is a very rare and aggressive neoplasm. The characteristic feature of this disease is a rapid hematogenous spread, mainly to the lungs and brain, which largely defines clinical signs of the disease and complicates the diagnosis. Gastrointestinal metastases are rare, and of those, only few cases with gastric location have been reported. There are publications describing choriocarcinoma syndrome (CCS). As a rule, it presents in patients with an advanced disease and is characterized by hemorrhage from metastatic foci, leading to hemoptysis and gastrointestinal bleeding. CCS development is associated with poor prognosis and high mortality. This article describes a case of testicular CC with rare few gastric metastases, complicated by CCS.
