[Krukenberg's tumor: still a somber prognosis. 4 cases].

The authors report four cases of Krukenberg's tumour. They point out its rarity and that the diagnosis can come as a surprise on histological examination. The tumour always has Signet ring cells. How the ovary comes to be involved is not known as yet. Treatment is mainly surgical with added chemotherapy but the prognosis is still very poor indeed.
