This page is to collect my pathology study aids in one place from my recent Inktober challenge art where I drew a pathology-related drawing for every day in October.
Day 1 – A primer on signet rings.
Courtesy of @MatthewZaba: Lung adenocarcinomas with ALK fusion are significantly more likely to have abundant signet ring cells.
Courtesy of @gibbspath: People with germline mutations in the CDH1 gene are at risk for this in the stomach and invasive lobular carcinoma of the breast.
Courtesy of @DrAHLAMN1: It is sneaky in GIT so you may need to request some IHC as I saw a case of metastatic breast lobular ca in the stomach which look like signet ring ca
Day 2 – Brain tumours by anatomical location
Day 3 – Echinococcus, the causal organism of hydatid cysts
Day 4 – A day in the life of a frozen section.
Day 5 – The life of a B cell from its origin in the bone marrow to its maturation in the lymph node, and all the markers it gains and loses along the way.
Day 6 – two different causes for enlarged lymph nodes, one benign and one malignant
Day 7 – a stroll through the enchanted forest of adnexal neoplasms!
Day 8 – This sketch focuses on vascular lesions in the brain – aneurysms, AVMs, and cavernomas
Day 9 – A few translocation associated sarcomas If you want to learn more, check out the sarcoma videos by @JMGardnerMD on YouTube.
A great tip – these are usually not associated with significant pleomorphism!
