Abstract

Carcinosarcomas are biphasic neoplasms composed of epithelial and mesenchymal elements. They are most commonly found in the uterus, with rare involvement of the fallopian tubes. Here, we present a case of primary carcinosarcoma of the fallopian tube. On CT and MRI imaging, it manifested as a tubular heterogeneous enhancing mass, along with necrosis and hemorrhage.

  Fig. 1. 76-year-old female with primary fallopian carcinosarcoma. A. Coronal image of the dynamic abdominal CT scan demonstrates a lobulated hypoattenuating mass (arrow) and normal ovary (arrowhead). B. T2-weighted image shows a large heterogeneous, low signal intensity mass (arrow) and normal ovary (arrowhead). C. T1-weighted image shows relatively low signal intensity of tumor (arrow) with central regions of necrosis and hemorrhage in right fallopian tube (arrowhead). D. Contrast enhanced axial MRI shows heterogeneous enhancement of the tumor (arrow).

  Fig. 2. Histopathologic findings of a surgical specimen in 76-year-old female with primary fallopian carcinosarcoma. A. Gross specimen: gross finding of right fallopian tube reveals markedly hemorrhagic and fusiform dilation with bulging tumor mass. The sero-sal surface is partially exposed by the tumor mass. However, right ovary is grossly intact (arrow). B. Microscopic examination (hematoxylin and eosin stain): high power field reveals spindle to round tumor cells with pleomorphic nuclei, vesicu-lar chromatin, and prominent nucleoli. C, D. Immunohistochemistry: diffuse strong positivity of vimentin (sarcoma component) (C) and focal positivity of epithelial membrane antigen; carcinoma component (× 400) (D).
