They say imitation is the sincerest form of flattery...
So I suppose that's what's happening with this dedifferentiated liposarcoma trying it's best to look like a myxoid liposarcoma 👯

CW: Duodenal parasite under my microscope
Here’s a case of duodenal #Giardiasis (causative organism Giardia lamblia) at 200x magnification. The #Giardia organisms are somewhat tear-drop shaped and resemble falling leaves, overlying the surface of the duodenum (the first segment of small bowel after the stomach). The duodenal mucosa is inflamed.

CW: A case of endometriosis under the microscope
A really florid case of #endometriosis down my #microscope on low power magnification. This is a cross section of small bowel (the compressed lumen visible on the right). The endometrial glands (left of my black line) are expanding and distorting the muscular wall of this segment of bowel. There are fibrovascular adhesions overlying the outside surface (the serosa) of the bowel.
Endometriosis is the presence of endometrial tissue outside the uterus (most often around the ovaries and adjacent structures - but can occur anywhere). It causes significant morbidity from pain, infertility and an associated risk of ovarian cancer.

quite a nice summary—just of note
because a surgeon was asking me
about this the other day—IDH1/2
mutations are seen in both benign
and malignant cartilaginous tumours.cartilage is always so weird 🤷🏻♂️
