Primary ovarian cancer presenting with axillary lymph node metastases: a report of two cases.

BACKGROUND: Axillary lymph node metastasis of primary ovarian cancer is rare.

CASE I: A 74-year-old woman presented with a 2 x 2 cm hard, mobile mass in the right axilla. She had a history of stage IIIA epithelial ovarian cancer which was diagnosed and treated four years previously. A right lateral wall involvement of the rectum was detected in abdominal tomography. A right axillary lymph node dissection and low anterior resection of the rectum were performed. Histopathologic examination showed ovarian epithelial serous papillary adenocarcinoma metastases to axillary lymph node and the rectum.

CASE 2: A 38-year-old woman presented with a 3 x 2 cm hard, mobile mass in the right axilla. She was treated surgically and by systemic chemotherapy with a diagnosis of stage IIIA epithelial ovarian cancer two years previously. A trucut biopsy was taken from the enlarged axillary lymph node, and histopathological examination revealed metastases of primary ovarian cancer. Complete axillary lymph node dissection was performed and metastases of ovarian papillary adenocarcinoma were found in 11 of the 30 lymph nodes.

CONCLUSION: Supradiaphragmatic lymph node involvement of primary ovarian cancer is very rare. We report here two cases presenting with axillary metastases of ovarian cancer.
