Background: Ovarian cancer groin lymph nodes metastases are rare. Only one case of disease spread isolated to the groins has been reported in the English literature. We report the case of a patient with bilateral inguinal lymphadenopathy due to tumor metastases and in which tumor origin was diagnosed using [(18)F]fluorodeoxyglucose positron emission tomography (PET).
Case report: This is the first case of bilateral groin lymph nodes as sole site of metastases from ovarian cancer. Primary origin was identified using PET.
Conclusions: In rare cases, the ovaries can directly metastasis to the groin even in a relatively initial tumor growth phase. PET may play a role in the diagnosis of occult ovarian tumors.
