Fallopian tube cancer incidentally diagnosed during loaparoscopy for metastatic adenocarcinoma of unknown primary lesion: Case report

We report a case of fallopian tube cancer incidentally diagnosed during laparoscopy for metastatic adenocarcinoma of unknown primary lesion. A 60-year-old woman was found to have two intraperitoneal calcific masses, which biopsy revealed to be a metastatic malignancy with an unknown primary site. She was asymptomatic, and the primary site was not identified in the imaging evaluations, including transvaginal ultrasonography. Diagnostic laparoscopy was performed and revealed papillary tumor-like lesions in the right fallopian tube. The laparoscopy was immediately converted to laparotomy. Total hysterectomy, bilateral salpingo-oophorectomy, and an omentectomy were additionally performed. The histopathologic diagnosis was primary serous adenocarcinoma of the fallopian tube. The patient received adjuvant chemotherapy. At 8 postoperative months, no signs of recurrence were observed. In this case, the diagnostic laparoscopy was more useful for detecting the primary small-volume fallopian tube cancer than ultrasonography, CT, MRI, and PET-CT. Laparoscopy might be taken into consideration as one of tool for revealing the obscure primary lesion in abdominal cavity.
