Slide 78.Pyosalpinx, Fallopian tube

A. Brief Descriptions:

  1. Pus collecting in the fallopian tube.

B. Gross Findings:

  1. Distention of the tube which is filled with pus.

C. Micro Findings:

  1. Swelling and edema in the plicae of the tube.

  2. Pus in the lumen.

  3. Thickened tubal wall with infiltration of acute & chronic inflammatory cells.

D. Others:

  1. Severe inflammation in the tube may spread to the adjacent ovary, resulting in a tubo-ovarian abscess (TOA).

  2. Occlusion of the fimbrial end of the tube prevents release of the tubal contents, so that a pyosalpinx may result.
