Surgical Management of an Extragonadal Trabecular Carcinoid Tumor: A Case Report and Review of the Literature

Extragonadal malignant transformation of a teratoma is rare, with only six reported cases in the literature. We report a case of a 33-year-old gravida 4 para 2 woman who had incidentally discovered bilateral pelvic masses, which were followed radiographically for nine years. She then underwent surgical resection, which revealed metastatic trabecular carcinoid involving lymph node tissue (left retroperitoneal pelvic mass), and trabecular carcinoid arising in a background of mature teratoma (right presacral mass). This case illustrates the indolent nature of this tumor and the importance of complete surgical resection.
