Chronic tubal pregnancy without positive pregnant tests, a rare but possible scenario.

OBJECTIVE: Chronic ectopic pregnancy is a variant of ectopic pregnancy featured with a low or normal serum beta-human chorionic gonadotropin (ß-hCG) test. Obscure clinical presentations and non-specific images make chronic ectopic pregnancy a diagnostic dilemma until now. CASE REPORT: A 40-year-old female was misdiagnosed as tubo-ovarian abscess initially due to chronic lower abdominal pain, negative pregnancy test, and a complicated pelvic mass on abdominal CT scan and serial follow-up ultrasonography. Diagnostic laparoscopy was performed because of persistent pelvic mass with abdominal pain and irregular vaginal bleeding. Left tubal salpingectomy was performed and pathology reported a hematocele with inactive trophoblast tissue. Chronic ectopic pregnancy was proved. The symptoms resolved completely after our surgery. CONCLUSION: An abnormal adnexal mass with a history of recent pregnancy could still be possible for chronic ectopic pregnancy even with a negative pregnancy test. Diagnostic laparoscopy and pathology confirmation could be helpful when the clinical manifestation is confusing.

Exceptional widespread, life threatening lung metastasis in stage IA ovarian endometrioid carcinoma: A case report.

OBJECTIVE: Low-risk, early stage, ovarian endometrioid carcinoma seems to have little chance to recur in clinical practice. Such a patient developed widespread, life-threatening pulmonary metastases is also extreme rare and is worthy to be reported. CASE REPORT: A 53-year-old female, who was diagnosed to have stage IA, grade 2, ovarian endometrioid carcinoma, developed a life threatening widespread lung metastasis in 2 years after primary surgery. She received salvage systemic chemotherapy with paclitaxel plus carboplatin. Bevacizumab was added after occurrence of paroxysmal supraventricular tachycardia during chemotherapy. The patient had clinical improvement and radiological stable after systemic therapy. CONCLUSION: Our case report enhances the aggressive post-operative surveillance including chest field would still be recommended even in the low-risk patients. To detect distant metastases earlier probably has higher chance of cure by systemic therapy.
