Introduction:
Ovarian cancer with metastatic axillary lymph node is a very rare entity. This study aims to report a case of recurrent ovarian cancer presenting with isolated axillary lymph node metastasis.
Case Presentation:
We report a case of a 58-year-old patient with recurrent ovarian cancer in the axillary node and a suspected lesion in the ipsilateral breast. One year before recurrence, the patient was diagnosed with FIGO stage IIIC ovarian cancer and was treated with primary debulking and paclitaxel-carboplatin adjuvant chemotherapy. Biopsies of the breast lesion, right and left axillary lymph node yielded a fibroadenoma in the breast and a metastatic carcinoma in the axillary node. Immunohistochemistry stains of the left axillary node biopsy specimen was positive for CK7, P53 and PAX-8 markers, and negative for CK20 and GCDFP-15 markers. Immunohistochemistry results combined with a history of ovarian cancer helped confirm the ovarian origin of axillary lymph node metastasis.
Clinical Discussion:
Recurrent ovarian cancer presenting with isolated axillary lymph node metastasis is rare. Immunohistochemistry combined with medical history is essential for definitive diagnosis in this situation. PAX-8 and GCDFP-15 help to differentiate the origin from the breast or the ovary.
Conclusion:
Oncologists and pathologists should recognize this rare clinical scenario for early diagnosis and treatment. Detailed medical history, imaging, and immunohistochemical studies on biopsy specimen should help reach accurate diagnosis.
