The growing teratoma syndrome.

C J Logothetis, M L Samuels, A Trindade

    Cancer
    |October 15, 1982
    PubMed
    Summary

    Recurrent mature teratomas can grow after chemotherapy in patients with metastatic mixed germ-cell tumors. Surgical resection of these benign growths ensures disease-free survival.

    Area of Science:

    • Oncology
    • Surgical Pathology

    Background:

    • Metastatic mixed germ-cell tumors (GCTs) are typically treated with chemotherapy.
    • Chemotherapy aims to eradicate malignant cells, but residual masses can occur.

    Observation:

    • Six patients with metastatic GCTs developed solitary enlarging masses post-chemotherapy.
    • These masses, located in the lungs or abdomen, were surgically resected.
    • Histological examination revealed mature teratoma, lacking malignant features.

    Findings:

    • The teratomas exhibited growth, attributed to either expansile cysts or firm mass formation.
    • All six patients achieved disease-free status after surgical intervention.
    • No further therapy was required post-resection.

    Implications:

    • This case series highlights an unusual post-chemotherapy phenomenon: the growth of benign teratomas.
    • Early surgical recognition and resection are crucial for successful salvage in these patients.
    • Awareness of this clinical scenario can prevent unnecessary aggressive treatments for benign lesions.
