STROMAL TESTIS TUMORS IN CHILDREN: A REPORT FROM THE PREPUBERTAL TESTIS TUMOR REGISTRY

Abstract

Stromal testis tumors are rare. Data from the Prepubertal Testis Tumor Registry confirms the benign behavior of most of these tumors. However, undifferentiated stromal tumors may exhibit metastatic behavior. A high index of suspicion is appropriate when there are a large number of mitotic figures, the tumor is poorly differentiated or when local invasion is present in the primary tumor. Metastatic evaluation and close followup are warranted for this select group of patients.
