Fatima Shamsuddin posts MTC frozen‑final

- Pathologist Fatima Shamsuddin shared a frozen‑to‑final correlation on a 9 cm thyroid mass diagnosed as medullary thyroid carcinoma, including IHC (calcitonin+) and RET mutation notes. - Syed Z. Ali also posted highly cellular direct‑smear images from an MTC FNA, emphasising classic cytologic features for recognition on aspirates. - The cases underscore deferring definitive subtype calls on frozen when cytology and IHC are discordant, and highlight visual smears useful for on‑site adequacy and triage.
