Giant pure ovarian dysgerminoma in a young 19-year-old patient

Abstract

Ovarian dysgerminoma is a very rare neoplasm. It occurs mostly in young women
with nonspecific clinical manifestations, although they may express abdominal
pain, sensation of mass and menstrual alterations. We report the case of a young
multiparous 19-year-old female patient with sensation of intra-abdominal mass,
of progressive growth and associated with oppressive pain. On tomographic
examination an ovarian-dependent adnexal mass was found, so she underwent a
right adnexectomy and freezing biopsy plus staging. Macroscopic evaluation revealed
a tumor measuring 25 x 20 x 13 cm, weighing 5,760 grams. By microscopic evaluation
and immunohistochemistry studies it was diagnosed as pure dysgerminoma. Based
on the average size and history, it was classified as a giant dysgerminoma.
