It's a 46 year old female. It was partially calcified at the area next to the kidney. It was sort of attached to the renal capsule, but hard to tell if that is where it is coming from.

Haven't seen any mitoses.

I have no idea what to call it. 😳 will let you know after signout.

That's our best guess, but there are no really obvious smooth muscle cells (although nuclei look like it). Stains are ordered

Actin (Muscle specific)
Desmin
CD34
BCL2
S100
HMB 45

Desmin

CD34 (staining vessels only)

S100 negative.
Guess it's a leiomyoma. Kind of wanted something a little more different than a boring old leiomyoma. Oh well. 😳
