Key result
Radical excision of benign mediastinal teratomas was successful without recurrence in seven of eight patients, while one patient with infiltrative growth died 9 months postoperatively.
Observational (n=8)
Radical excision of benign mediastinal teratomas is associated with good outcomes and no recurrence, whereas incomplete resection can be fatal.
May support radical excision for benign mediastinal teratomas; leaves open optimal management of infiltrative cases.
Mediastinal teratomas are rare, constituting only 8-13% of tumours in this region. Teratomas often contain structures from all three germ layers, and 15-20% are malignant. A report is presented of eight patients operated on in 1978-1985 for mediastinal teratoma histologically classified as benign. Radical excision was performed in seven cases, but one tumour could not be radically removed because of infiltrative growth into vital structures, and the patient died 9 months postoperatively. In the other seven cases, including four with unusually rapid and dramatic tumour development, no signs of recurrence have appeared.

Saabye et al. (1987) conducted an observational in Mediastinal teratoma (n=8). Surgical excision was evaluated on Tumor removal and recurrence. Radical excision of benign mediastinal teratomas was successful without recurrence in seven of eight patients, while one patient with infiltrative growth died 9 months postoperatively.
