omental milky spots
A popular term for a type of lymphoid tissue consisting of clusters of leukocytes embedded in the omentum which collect fluids, particulate material and cells. Milky spots increase in size in patients undergoing peritoneal dialysis. In contrast to conventional lymphoid tissue, omental milky spots develop in absence of lymphoid tissue-inducer cells, but require the chemokine CXCL13.
