subserosa

Tumor deposit(s) in the subserosa, mesentery, or nonperitonealized pericolic or perirectal tissues without regional nodal metastasis.

The tela subserosa (or just subserosa) is a layer of tissue between the muscularis and serosa.

In controls the positive reaction was limited to the lamina propria, while in Crohn's disease reactivity was also found in the submucosa and subserosa.
