Two Concurrent Cancers in a 19-Year-Old Patient: Yolk Sac Ovarian Tumor and Metastatic Gastrointestinal Tract Malignancy-Case Report.

BACKGROUND

Two concurrent malignancies present in a young person is an extremely rare condition. Diagnoses of gastric cancer primarily concern older patients. There are very few reports of concomitant Krukenberg tumor and germ-cell ovarian malignancy.

CASE: A 19-year-old girl was admitted to the gynecologic oncology department with symptoms of advanced malignancy. Radiological imaging revealed disseminated neoplastic disease with bulky adnexal tumors. Cytoreductive surgery was performed, achieving no visible disease (T = 0 cm). The final pathology report confirmed metastatic mixed adenoneuroendocrine carcinoma (MANEC) in both ovaries, originating from the gastrointestinal tract. Moreover, the primary germ cell yolk sac tumor was found in the left ovary.

CONCLUSION

In cases of concomitant gastric and ovarian tumors, metastatic disease (Krukenberg tumor) should be considered in the differential diagnosis. This concerns even adolescent patients. In particular cases, including tumors with germ cell components, primary debulking surgery is crucial for prognosis.
