A funny looking polyp

This lesion was found in the ascending colon. 
WHAT IS THE MOST LIKELY DIAGNOSIS?

■ Lipoma

Hmm looks too translucent

■ Lymphangioectatic cyst

Well it looks cystic doesn't it!!!

■ GIST

I predict that the pillow sign will be positive

■ Serrated polyp

Doesn't look like a polyp

■ Adenomatous polyp

But the crypt pattern is normal !!!

explanation

The apparent lesion is covered with a normal layer of mucosa. In addition, it seems very soft.  However, the lesion looks more translucent than yellow!   Of course, it's another lymphangioectatic cyst !   Naturally, you confirm this by giving it a prod with your biopsy forceps.  If soft, its either a lipoma or a cyst.  If firm, it's either a GIST, leiomyoma or a metastasis (I guess).
