Ovarian cancer constitutes one of the most frequent malignant tumours in the female population not only in Poland. The screening of this tumour type is unsolved. The tumours are usually diagnosed in the advanced stage, thus the survival rate are usually poor. Their histopathological appearance has a wide variety, with the occurrence of numerous metastatic forms. Among the metastatic tumours, the primary tumours of the digestive tract occur the most frequently. They are known as the Krukenberg tumours. In these cases the choice of treatment is more difficult and prognosis is also worse in most cases with fatal outcome in one year. Early diagnosis and complete resection is the only possible hope. In this paper authors present three cases of Krukenberg tumour with nonspecific symptoms, difficulties during diagnostics, late beginning of treatment and poor prognosis.
