Hi #pathtwitter

Sorry I have been absent, but I have moved jobs!

I am now working in Perth, Australia for Pathwest and (soon for) @uwanews (as A/Prof).

Will get back to posting soon, in the meantime, here is an interesting colleague's case.

Let’s enjoy this cutie which pops up often on RISE and board exams, but not so frequently under the microscope! Once you see it, you’ll never forget it!

A beautiful case of Sex Cord Tumor with Annular Tubules (SCTAT):
• Positive for Calretinin, Inhibin, and WT-1
• Approximately one-third of cases are associated with Peutz-Jeghers syndrome (STK11 mutation)

An often-forgotten figure in the history of chemotherapy is Yellapragada Subbarow, the Indian chemist who discovered aminopterin, a folic acid antagonist. Aminopterin became one of the first chemotherapy agents used by Sidney Farber in the 1940s to induce remission in children with acute lymphoblastic leukemia, marking a pivotal moment in cancer treatment. Despite his groundbreaking contributions to medical science, Subbarow was, if I’m not mistaken, never granted a permanent faculty appointment at Harvard Medical School

Thank you all for taking part in the case I posted last Friday.

I chose one of the trickier fields to share with you, because of its educational value. The additional images provide more insight into the diagnosis.

Let's go over the answers 1 by 1🧵

“Pen Test” confirming true psammoma body (PB) as opposed to thick colloid (or mucin). Gentle pressure on the cover slip with the tip of a pen while looking at the fragment under the scope will radially fracture a true PB (Thyroid, FNA, PTC). Same fragment, before/after the test.

Without stains - name this lymphoma

Liver metastasis in adult.

Diagnosis? AE1/AE3 and Ki67 in next tweet.

Can you tell the origin of the tumour?

[Mark Ong @DrMarkOng]

Biopsies of a nasal cavity mass from 40 year old.

Unusual case that was eventually diagnosed on the resection specimen. Not my area of expertise, but was sent as possible lymphoma.

Differentials and how would you approach this?
