Abstract

Primary fallopian tube carcinoma (PFTC) is a rare gynecological cancer that is very difficult to diagnose preoperatively. Here, we report the case of a 66-year-old female patient with PFTC that was diagnosed preoperatively on the basis of the characteristic features on endoscopic ultrasound (EUS) elastography and fine needle biopsy (FNB). EUS showed a sausage-shaped hypoechoic mass, 8 cm in size, with irregular margins and heterogeneous internal echoes extending to both adnexa. EUS elastography revealed that the mass had a blue color pattern, representing hard stiffness, and a heterogeneous green/red color pattern distributed outside the tumor, representing intermediate stiffness. Histopathologic analysis of the FNB and operative specimens confirmed the diagnosis of fallopian tube carcinoma. This is the first reported case of a combined EUS elastography and FNB of an adnexal mass leading to a preoperative diagnosis of fallopian tube carcinoma.
