《Slide 78.》Pyosalpinx, Fallopian tube
A. Brief Descriptions:
Pus collecting in the fallopian tube.
B. Gross Findings:
Distention of the tube which is filled with pus.
C. Micro Findings:
Swelling and edema in the plicae of the tube.
Pus in the lumen.
Thickened tubal wall with infiltration of acute & chronic inflammatory cells.
Severe inflammation in the tube may spread to the adjacent ovary, resulting in a tubo-ovarian abscess (TOA).
Occlusion of the fimbrial end of the tube prevents release of the tubal contents, so that a pyosalpinx may result.
