Abstract
We report a rare case of recurrent ovarian cancer presenting as a round ligament metastasis. A 44-year-old woman presented with a lower abdominal mass. Computed tomography showed a pelvic mass. Primary surgery was performed. A histopathological examination showed an ovarian serous adenocarcinoma of Stage IIIb. The patient received 6 cycles of paclitaxel and carboplatin. Almost 2 years after the initial operation, the patient noticed a left inguinal mass. Computed tomography showed a left inguinal mass, 18 mm in size. An excisional biopsy was performed and the tumor was found to originate in the left round ligament. A histopathological examination showed serous adenocarcinoma and there was no evidence of lymph node tissue. Recurrence of ovarian cancer in the round ligament is extremely rare. This unique case suggests, however, that the round ligament in rare cases may be a recurrence site for ovarian cancer, and that accurate differentiation including confirmation by diagnostic imaging and excisional biopsy, is necessary for a definitive pathological diagnosis.
Highlights
The majority of women with ovarian cancer present with advanced stage disease
We found 1 case report of recurrent endometrial cancer stage Ia, originating in the round ligament [10]
The decision as to whether adjuvant chemotherapy is indicated must be carefully considered in each case. This case presents an unusual example of a recurrence site for ovarian cancer
Summary
The majority of women with ovarian cancer present with advanced stage disease. A complete clinical remission after surgical cytoreduction and platinum-based chemotherapy can be achieved in 80-90% of these patients. In August 2009, her serum CA125 levels declined to 5 U/ml She received adjuvant radiotherapy (WB 50Gy/25 f) for breast cancer in October 2009. Almost 2 years after her initial ovarian cancer operation, the patient noticed a left inguinal mass. CT showed a left inguinal mass, 18 mm in size (Figure 2), but no abnormal mass in chest, abdomen or pelvis This mass was located on the fascia and medially to the femoral vein. A fine-needle aspiration of the left inguinal mass revealed cells consistent with adenocarcinoma, but it was difficult to confirm the location of the primary lesion. She underwent an excision biopsy of the left
