This was really a first, out of the thousands of cysts I have removed, I truly have never seen a rectangular cyst. It likely took that shape because the contents were dry and packed in tight in the sac, and the downward pressure from the arm resting on in it slowly pushed it into a rectangle.
HAVE YOU EVER SEEN A RECTANGULAR CYST!? Deep cavernous pocket in the armpit removed. Axilla pop. Mr. PopZit 0710
