Abstract
|
|
|
Sinonasal teratocarcinosarcoma is a very unusual malignant neoplasm. This neoplasm histologically
consists of an epithelial elements and one or more mesenchymal components with immature and
embryonal characteristics. These tumors, which is variously termed as malignant teratoma, blastoma,
teratocarcinoma, or teratocarcinosarcoma, probably comprise a group of neoplasm by their similar
characteristics of histology and biology. This is a case of teratocarcinosarcoma in a 67-year-old male,
involving the right maxillary sinus and ethmoid sinus with invasion of hard palate. The tumor was totally
resected via total maxillectomy, and the patient was given post-operative radiotherapy. A follow-up PNS
CT after 7 months of the surgery showed no recurrence of the lesion or residual tumor. Extensive tumor
necrosis, rapid growth and local destruction are the prominent features of this neoplasm. The clinical
presentation, pathological features and clinical course of this unusual malignancy are discussed with a
review of the literature.
