Dysgerminoma of ovary

Description

A malignant germ cell tumour arising from the ovary. Morphologically, it is identical to seminoma and consists of a monotonous population of germ cells with abundant pale cytoplasm and uniform nuclei. The stroma invariably contains chronic inflammatory cells, mostly T-lymphocytes. It responds to chemotherapy or radiotherapy and the prognosis relates to the tumour stage.
