OVARY - Dysgerminoma

The specimen is a markedly enlarged left ovary with an oviduct stretched over its superior surface. The ovary is expanded and replaced by an homogeneous brown tumour mass with focal areas of cyst formation.
The patient, a 9 year old female, presented with a two month history of left flank pain associated with intermittant vomiting. She was treated for a urinary tract infection and the symptoms persisted. On examination a mass was palpable above the symphysis pubis which persisted after micturition. Laparotomy showed a large left ovarian tumour which was completely removed.
