Sorry for the late update, but I was not able to post the necessary data here.
 
The tumor presented as a huge tumor mass protruding from the cervix. The tumor measured 11x7x6.5 cm, mimicking a large polyp. Histopathology revealed a diffuse lympho-plasmacytic infiltration confirmed by immunohistochemistry. Detailed IHC panel was performed: AE1-AE3 (-), desmin (-), SMA (-), c-Kit (CD117) (-), CD56 (-), Synaptophysin (-), Chromogranin (-). Of the hematologic markers, CD79alpha was positive (not shown here) whereas Bcl-6 was negative.

Thank you for your comments.
