Metastatic carcinoma to testis is an extremely rare but interesting phenomenon. Over a period of nineteen years 300 testicular tumors were diagnosed in our department, and of which 10 were metastatic carcinoma from other sites. Four of these patients (40%) presented as testicular lump of which two were already diagnosed cases of squamous cell carcinoma larynx and adenocarcinoma of lung, and two had occult primary in the kidney and colon. However six (60%) were detected incidentally in the orchiectomy done as a part of hormonal therapy for carcinoma prostate.
