Abstract
The incidence of secondary testicular tumors ranges from 0.02 to 2.5% among autopsies in general. With the exception of leukemias and lymphomas, prostate cancer is the most common primary site. It is diagnosed in autopsies or incidentally, following therapeutic orchiectomies in more advanced stages of the disease. In the present report, we show a case of testicular metastasis derived from prostate neoplasm whose clinical presentation as a single metastasis was similar to a primary testicular neoplasm. The diagnosis was evidenced after orchiectomy by histological examination and immunohistochemical tests.
Highlights
Prostate adenocarcinoma is the most frequently diagnosed neoplasm in men and its natural history is largely known
The testis is a rare site for prostate cancer metastases and is usually found in autopsies or incidentally after therapeutic orchiectomies for advanced disease
We report one case of testicular metastasis from prostate cancer mimicking a primary testicular tumor in a young patient
Summary
Prostate adenocarcinoma is the most frequently diagnosed neoplasm in men and its natural history is largely known. The most common metastatic sites are iliac lymph nodes, bones and lungs, followed more rarely by bladder, liver, adrenal and brain [1,2]. The testis is a rare site for prostate cancer metastases and is usually found in autopsies or incidentally after therapeutic orchiectomies for advanced disease.
