List of Commonly Misspelled Medical Terms

This is a list of commonly misspelled medical terms. The words that are in bold are spelled correctly, but could still be mean't for something else depending on the context. The terms with "vs" between them are often confused with each other and the ones with "=" are typically interchangeable.

Use the green search box at the bottom of the page or the alphabet below to find a specific one more quickly. You can also press the Ctrl and F keys on your Windows computer keyboard, or Command and F keys on your Mac keyboard. This will open a text box where you can type the letters. Then press Enter/Return on your keyboard to be brought to that word.

Simply click the blue underlined terms to learn more about them. Use the comment section at the bottom of the page if you don't see the word you are looking for or if you know one that is commonly misspelled that isn't listed. I will be adding more periodically.
