ADENOCARCINOMA OF THE RETE TESTIS

Adenocarcinoma of the rete testis is a rare tumor. Histologic diagnosi s is difficult, and in the past the tumor may have been incorrectly id entified in a number of cases, leading to misleading information on th e nature and behavior of this neoplasm. We present the case of a 39-ye ar-old man with a long history of a small left hydrocele, who was lost to follow-up and presented again 2 years later with testicular discom fort. Sonographic findings were consistent with a testicular tumor. Hi stology confirmed low-grade adenocarcinoma of the rete testis, the fir st reported tumor of this grade. Previously reported cases of rete tes tis carcinoma are reviewed.
