Mature teratoma is the most common germ cell tumor of the ovary. The tumor is essentially a benign neoplasm and surgical resection of the tumor is the treatment of choice. Recurrence with colorectal involvement after surgical removal of the primary lesion is exceedingly rare and has not been reported in Korea. We present a 43-year-old patient with a rectal mass who had already undergone left oophorectomy due to mature cystic teratoma and right oophorectomy due to hemorrhagic corpus luteum. The rectal mass was composed of a mature teratoma tissue. We postulate that leakage of the tumor elements from the cyst wall led to peritoneal tumor implantation and invasion to the rectal wall.

We report a case of small cell lung cancer that turned out to be a metastatic teratoma from the nasal cavity rather than a new primary cancer. A 54-year-old woman was diagnosed with an immature teratoma of the nasal cavity with a predominant neuroblastomatous component. Small cell lung cancer was detected by bronchoscopic biopsy 21 months later, and it was treated with concurrent radiochemotherapy as if it had been a new primary cancer. Since a recurrent tumor containing fat- like density grew slowly on the serial chest CT scans after achieving complete response, we reached the conclusion that the small undifferentiated cells could be metastatic neuroblastomatous components from the immature teratoma of the nasal cavity.

We report an unusual case of 9.5-cm-sized embryonal rhabdomyosarcoma arose from a mediastinal mature teratoma in a 46-yr-old man. A man presented with chest trauma as a result of an accident at 10 September 2011. On chest X-ray, an anterior mediastinal mass was detected. To obtain further information, chest computed tomography (CT) with contrast enhancement was performed, revealing an anterior mediastinal mass. Complete surgical excision was performed and entire specimen was evaluated. Pathologic diagnosis was embryonal rhabdomyosarcoma arising in mature cystic teratoma. After surgical excision, two cycles of dactinomycin-based chemotherapy were performed. Lung metastasis was detected on follow up CT in September 2012, and wedge resection was performed. Pathological finding of the lung lesion showed same feature with that of primary rhabdomyosarcoma.
