Pure granulosa cell tumour of the testis. Report of a case and review of the literature.

A case of pure granulosa cell tumour of the testis is described. To the author's knowledge this is the 5th documented case reported in the literature. The patient, a normal 44-year-old male noted a gradual right-sided testicular enlargement for a few months. There was no clinical evidence of gynaecomastia or any endocrinological abnormalities. Orchidectomy was performed and the testis was found to contain a soft yellow, well-circumscribed tumour which microscopically showed the typical appearance of a pure granulosa cell tumour. The patient was well and disease free 3 years after diagnosis. The literature concerning this entity is reviewed and discussed.
