Correct Answer- A
Ans. is 'a i.e., CD 117
Immunohistochemistry
◦ Following markers are present in GISTs:
CD 117 (c kit)
->95%
D
I
i)
CD 34
70%
iii) Smooth muscle actin
5%
. CD 117 (c kit) is considered the most specific marker
○ CD 117 (c kit) immunoreactivity is the best defining feature of
GISTs distinguishing them from true smooth muscle tumors
(leiomyoma) and tumors arising from neural crest.
○ Although CD 117 (c kit) is considered the most specific marker for
GIST, it is not pathognomonic of GIST as other tumors may also
express CD 117. These tumors include mast cell tumor, germ cell
tumors (seminomas), leukemias, malignant melanoma,
angiolipomas, and some sarcomas

Correct Answer-B
Scans to differentiate adrenal adenoma from adrenal metastasis are:
.CECT
• Chemical shift MRI
.FDG-PET
PETscan has almost 100 % sensitivity for detecting adrenal metastasis. so a negative
study excludes the possibility of adrenal mets. But adenomas can give false positive test.

The tumor is oropharygeal teratoma, which
contains derivatives from all three germ layers.
The tumor may include gut bone skin teeth
These tumors arise from pluripotent stem cells
that differentiate into any of three germ layers
forming tissues of all three germ layers
