Patients presenting with Stage I seminoma of the testis have an excellent prognosis after treatment by orchidectomy and prophylactic radiotherapy to the paraaortic and pelvic lymph nodes. Only 2% subsequently recur but relapse in these cases has been reported in unusual sites such as the prostate and mesentery. We report a case of Stage I seminoma relapsing in another rare site for secondary malignant deposits, the palatine tonsil. This case further illustrates the favourable prognosis for this tumour even in cases of distant recurrence.
