ABSTRACT
A 54-year-old woman was found to have a gastric ulcer on medical examination, but the course with normal medication was monitored. Nine months later, she was transported to our hospital. A huge gastric ulcer was revealed and biopsy specimen indicated MALT lymphoma. We performed a total gastrectomy because it perforated before therapy, leaving a massive tumor. The final pathological diagnosis was DLBCL. She was administered rituximab-CHOP therapy for the remnant lesions. After 6 courses, the lesions disappeared. The patient has been alive without any recurrence or metastasis five years after surgery.

We reported a case of retroperitoneal immature teratoma with embryonal carcinoma. First, pathological diagnosis of sarcoma was made by fine needle aspiration, then secondary pathological diagnosis of suspected malignant schwannoma was made by a partial resection. The final pathological diagnosis by operation was immature teratoma with embryonal carcinoma. The preoperative diagnosis was difficult in this case, and the tumor had grown too large after partial resection to surgically resect. The effective chemotherapy reduced this tumor enough to allow successful resection. Although the prognosis of immature retroperitoneal teratoma is poor, this case has survived 10 years after operation without metastasis and recurrence.
