𝐌𝐞𝐧𝐢𝐧𝐠𝐢𝐨𝐦𝐚𝐬 are tumours of the 𝐦𝐞𝐧𝐢𝐧𝐠𝐞𝐬, which are the fibrous layers covering the brain. Although these tumours are technically benign, they compress the brain causing pretty significant damage!

𝐌𝐞𝐬𝐨𝐭𝐡𝐞𝐥𝐢𝐨𝐦𝐚 is a tumour that arises from the 𝐦𝐞𝐬𝐨𝐭𝐡𝐞𝐥𝐢𝐮𝐦, the lining of the body cavities. These linings include the 𝐩𝐥𝐞𝐮𝐫𝐚 (lining the thorax), the 𝐩𝐞𝐫𝐢𝐭𝐨𝐧𝐞𝐮𝐦 (lining the abdomen) and the 𝐩𝐞𝐫𝐢𝐜𝐚𝐫𝐝𝐢𝐮𝐦 (around the heart).

𝐋𝐲𝐦𝐩𝐡𝐨𝐦𝐚 is a tumour of the 𝐥𝐲𝐦𝐩𝐡𝐨𝐜𝐲𝐭𝐞𝐬, one of the body’s major white blood cells. Because the white blood cells are found in the blood, these tumours can occur pretty much anywhere, and are always considered 𝐦𝐚𝐥𝐢𝐠𝐧𝐚𝐧𝐭 (aggressive).

𝐔𝐭𝐞𝐫𝐢𝐧𝐞 𝐚𝐝𝐞𝐧𝐨𝐜𝐚𝐫𝐜𝐢𝐧𝐨𝐦𝐚𝐬 are tumours of the uterine lining. The risk of these tumours increases with the age of the animal, and they are particularly common in rabbits!

𝐋𝐮𝐧𝐠-𝐝𝐢𝐠𝐢𝐭 𝐬𝐲𝐧𝐝𝐫𝐨𝐦𝐞 is a pretty interesting situation that can occur with lung tumours! In this syndrome, the tumour 𝐦𝐞𝐭𝐚𝐬𝐭𝐚𝐬𝐢𝐳𝐞𝐬 (spreads) to the toes, which is a pretty unusual place for metastases to end up!

ould be fun to learn about the basic types of tumours. There is also a quiz on website if you want to test out your histopathology skills!

𝐓𝐫𝐚𝐧𝐬𝐢𝐭𝐢𝐨𝐧𝐚𝐥 𝐜𝐞𝐥𝐥 𝐜𝐚𝐫𝐜𝐢𝐧𝐨𝐦𝐚𝐬 are malignant tumours of the 𝐭𝐫𝐚𝐧𝐬𝐢𝐭𝐢𝐨𝐧𝐚𝐥 𝐞𝐩𝐢𝐭𝐡𝐞𝐥𝐢𝐮𝐦, a specialized epithelium found in the bladder, ureters and urethra.

𝐂𝐡𝐞𝐦𝐨𝐝𝐞𝐜𝐭𝐨𝐦𝐚𝐬 are tumours derived from the 𝐧𝐞𝐮𝐫𝐚𝐥 𝐜𝐫𝐞𝐬𝐭, which is a group of cells that develop into neurons and other nervous tissue. These tumours most commonly develop from the 𝐜𝐚𝐫𝐨𝐭𝐢𝐝 𝐚𝐧𝐝 𝐚𝐨𝐫𝐭𝐢𝐜 𝐛𝐨𝐝𝐢𝐞𝐬 near the heart.

𝐓𝐞𝐫𝐚𝐭𝐨𝐦𝐚𝐬 are a strange and rare type of tumour, primarily found in the ovaries of animals. These tumours can have hair, cartilage, and even bone growing within them!

𝐓𝐫𝐚𝐧𝐬𝐦𝐢𝐬𝐬𝐢𝐛𝐥𝐞 𝐯𝐞𝐧𝐞𝐫𝐞𝐚𝐥 𝐭𝐮𝐦𝐨𝐮𝐫𝐬 (TVTs) are one of the few known types of tumour that can be spread by contact, like an infectious disease. This is an extremely rare feature for a tumour to have!
