Osteosarcoma as Malignant Mural Nodule in Ovarian Mucinous Neoplasms of Intestinal Type: Report of 2 Cases.
McFarland M, Dina R, Fisher C, McCluggage WG.
Int J Gynecol Pathol. 2015;34(4):369-73.
Primary osteosarcomas of the ovary have been described either arising within a teratoma or as a pure neoplasm but, to the best of our knowledge, osteosarcoma occurring as a mural nodule in an ovarian mucinous neoplasm has not been reported.

Aygun B, Kimpo M, Lee T, Valderrama E, Leonidas J, Karayalcin G.
J Pediatr Hematol Oncol. 2003;25(5):410-3.
Previously, 10 cases of ovarian osteosarcoma have been reported in the literature: 5 were primary osteosarcoma of the ovary, 4 were associated with teratomas, and 1 was part of a malignant mixed mesodermal tumor of the ovary.

Extraskeletal osteosarcoma of the mediastinum after treatment of a mediastinal germ-cell tumor.
Ulusakarya A, Terrier P, Regnard JF, de Montpreville V, Munck JN.
Am J Clin Oncol. 1999;22(6):609-14.
Three years after four cycles of bleomycin, etoposide, and cisplatin (BEP) chemotherapy for a nonseminomatous germ-cell tumor of the mediastinum followed by complete resection of residual teratoma in a 21-year-old man, a mediastinal recurrence was diagnosed as an extraskeletal osteosarcoma.

CT findings of retroperitoneal malignant mesenchymoma.
Mukherji SK, Rojiani AM, Younathan CM, Ros P.

MM should be considered along with extraosseous osteosarcoma and teratoma in the differential diagnosis for unusual large heterogeneous retroperitoneal masses with massive calcification.

Primary osteosarcoma of the ovary. A case report.

Acta Pathol Jpn. 1991;41(4):311-7.
Therefore, it is doubtful that this tumor originated from teratoma or malignant mixed mesodermal tumor, and we conclude that this ovarian osteosarcoma arose through a neoplastic change in ovarian stromal cells.

Mediastinal mass following chemotherapeutic treatment of Hodgkin's disease: recurrent tumor or thymic hyperplasia?
Ford EG, Lockhart SK, Sullivan MP, Andrassy RJ.
J Pediatr Surg. 1987;22(12):1155-9.
Our experience from 1979 to 1986 includes 14 children aged 1 to 17 years (mean 7.4 years) who were identified with new or recurrent mediastinal masses during or after chemotherapeutic treatment for malignant disease (lymphoma 9, Wilms tumor 2, leukemia 1, osteosarcoma 1, malignant teratoma 1).

Z Kardiol. 1985;74(11):670-2.
Intracavitary ventricular tumors were found in 3 male patients (newborn, and 18 and 23 years old) by 2-D echocardiography (metastasis of an osteogenic sarcoma in the right ventricle, teratoma embryonale growing from the retroperitoneum into the right ventricle, rhabdomyoma of the left ventricle).

Clinically the metastasis of the osteogenic sarcoma presented as obstruction of the superior vena cava, whereas the teratoma embryonale imitated tricuspid valve disease.
