A retrospective review of 20 cases of testicular neoplasia in cryptorchid patients is presented. These cases serve to emphasize the need for more effective diagnosis and management of the undescended testis. The various clinical presentations, diagnostic modalities, prognostic indicators, and types of management are reviewed. Due to its inaccessibility and array of clinical presentations, the intraabdominal testies tumor continues to be a diagnostic challenge. Strict attention to diagnostic cues and adherence to the management practices presented here would hopefully result in an overall decrease in testis tumors in the post-pubertal male.
