Question:

EOD-Extension--Small Intestine: How do we interpret a pathology description of "extending through serosa and forming masses in the periserosal tissue" for a jejunum primary?

Discussion:

Answer:

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 55 [Invasion of/through serosa and adjacent connective tissue]. The description states the tumor extended through the serosa into periserosal tissue. The periserosal tissue in this case refers to adjacent connective tissue lying exterior to the intestinal wall and not the (sub)serosal tissue that lies exterior to the muscularis but inferior to the serosa. Analyze each case individually since pathologists are not consistent when using the above terminology.
