Nephrectomy for large, cystic #Renal-cell-carcinoma

1st pic - blue arrow shows normal-appearing kidney, black arrow shows obvious tumor visible from the outside.
2nd pic - bivalved view of "normal" looking portion of kidney. Blue arrow points to uninvolved kidney tissue and black arrow is the mass which takes up the vast majority of the kidney.
3rd pic - cut surface of cystic aspect of mass. You can see the tissue is all necrotic inside of the cystic space. Arrow shows that all of the tissue is involved by tumor and if you look closely, you can see the thin, white renal capsule running along the outer edge. It appears this mass started in the lower pole and grew outward in both directions. Unsure how long this has been growing but it is >20cm and, surprisingly, the patient is only in her 40s.

total #Thyroidectomy for a concerning nodule in the right lobe. First pic is the total thyroid from the front - how it would look on someone's neck if you were staring at them. Blue arrow points to the left lobe. 2nd pic shows a section of the left lobe which was unremarkable -- this is what the cut surfaces of normal thyroid tissue looks like. 3rd pic shows the cut surfaces of the right lobe, which show a pink-white, firm mass involving almost each cut section. 4th pic shows a close up of the mass, showing it extending to the black-inked capsule. You can see how there's none of the normal red-brown thyroid tissue remaining, as it has been totally replaced by tumor. Diagnosis ended up being papillary thyroid carcinoma. Back to the first pic, the orange arrow points to a lymph node which is just above the isthmus (portion of thyroid between the 2 lobes) and is unfortunately positive for metastatic papillary thyroid carcinoma.

right arm removed for recurrent pleomorphic undifferentiated sarcoma. Arrow in 2nd pic points to area of underlying tumor and the 3rd pic is a cut cross section through the mass. You can see the tumor involves a lot of the soft tissue, possibly invading into the bone as well. Blue arrow on 3rd pic shows an area of tumor , but the overall size was measured to be about 11cm.

bisected #Kidney showing a large #Renal-cell-carcinoma (orange arrow). The main mass is pushing on and displacing the renal pelvis, but does not appear to invade into it. The blue arrow points to a possible satellite tumor which does appear to focally involve the pelvis. Normal kidney tissue can be seen both superior and inferior to the main tumor.

bivalved #Kidney showing a very bizarre presentation of a #Renal-cell-carcinoma. The tumor appears to have started at the very edge of the cortex and grew outward. You can see the small point of attachment of the tumor to the kidney and you can see a thin capsule surrounding the tumor as well. Blue points to normal kidney (except for some benign-appearing cysts) and orange points to the large mass.
