Amass in transverse colon

This is what we dissected out from he transeverse colon of a middle aged lady. Entire ascending and transeverse colon was removed, to find only this little pedunculated mass with no features of local involvment or lymph nodes. Did we dissect out too much?

The middle and  ileocolic arteries have to be identified; middle colic artery has to be ligated; the ascending and most of the transverse colon are to be removed

Prepare the ileum for an ileotransverse anastomosis
The dissected specimen with the blackish lump (do you note the appendix poking out at the left?)
The mass within the colon, the walls of which are ...
... cut open
It has a stalk, and the base is surrounded by normal haustrous mucosa of colon
However, the surface is unlike any mucosa

An appendicectomy

This is the proverbial appendicectomy. For those who are not aquainted with the term, enjoy looking inside yourself.
Find the appendix (its that wormlike tube attached to the cecum)

Pull it out
Tie its base and supplying vessels
Cut it out
And there you go

Call them the newborn

Have you delivered anybody out of his mothers womb? Chances are, most of the time they are just cute angels.

They can make strange faces
They may be a little curved at wrong places

Sometimes, though, they are missing some limbs

Sometimes they are missing their skin

Or even their brain
