Greetings people!
Primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC).. Because both have the word primary and are associated with the hepatobiliary system, it's easy to mix em up.
Here's how I keep them straight -
The middle word is the key:
sclerOsing has an O
O for onion
O looks like a bead
biliAry has an A
A for autoimmune
A for antibodies
Periductal onion skin fibrosis on histology and beaded appearance (both strictures and dilation) on cholangiography is seen in primary sclerosing cholangitis.
Cholangitis and Colitis sound similar and that's how I make the Ulcerative colitis association with PSC!
Antimitochondrial antibodies are seen in primary biliary cirrhosis. It is autoimmune.
A also reminds me of the Attenuated bile duct epithelium due to destruction of interlobular bile ducts (those that course alongside the hepatic artery) by lymphocyte infiltration (Florid duct lesion).
Since autoimmune diseases are more commonly seen in females, PBC is also common in females.. So the other one, PSC, is seen in males!
Hope you all are doing awesome < 3
