Endocrine pathology: pituitary, thyroid and adrenal tumors for USMLE
Endocrine pathology is basically the "bread and butter" of the USMLE. It’s all about those feedback loops going haywire and the classic clinical presentations that follow!
Let's start with the "master gland"—the pituitary. Whether it's a prolactinoma causing galactorrhea or a GH-secreting adenoma leading to acromegaly, these are high-yield favorites. I'll pull up some key lessons to help you master the pituitary, thyroid, and adrenal tumors.

When it comes to the thyroid, the USMLE examiners absolutely love their histology. Whether it's the "Orphan Annie eye" nuclei of Papillary carcinoma or the psammoma bodies, you've got to be able to spot them.
Let me find a high-yield comparison table or image for thyroid cancers to help you differentiate between Papillary, Follicular, Medullary, and Anaplastic types.
This histopathology image is a goldmine for your USMLE prep! It perfectly breaks down the spectrum of thyroid cancer, from the well-differentiated Papillary Thyroid Carcinoma (PTC) with its classic papillary architecture to the highly aggressive Anaplastic Thyroid Carcinoma with its spindle cells and high mitotic activity.

And we can't forget the adrenals! Between Pheochromocytomas with their classic triad of "Pressure, Pain, and Perspiration" and those tricky pediatric Neuroblastomas, there's a lot to keep straight.
I'll grab some flashcards so you can test your recall on these high-yield adrenal facts and the associated MEN syndromes.

Those flashcards are perfect for drilling the MEN syndromes, which are essentially a "guaranteed point" if you can keep the 3 Ps, 2 Ps, and 1 P straight!
Before we wrap up, here are a few high-yield "Rezzy's Rules" for your exam:
Ready to see how much stuck? I'll set up a quick quiz on these endocrine tumors for you.
