Which term is used to describe a condition that is not a true tumor?

• A. Recurrent
• B. Semilunar
• C. Pseudotumor
• D. Synapse

Answer: (C)

When a lesion looks like a tumor but isn’t due to actual neoplastic cell growth, we call it a pseudotumor. The word “pseudo” means false, so a pseudotumor is a false tumor—a mass or lesion that mimics a tumor in appearance or symptoms but isn’t a true tumor. This distinction matters because the underlying process isn’t driven by uncontrolled cell proliferation. For example, pseudotumor cerebri presents with headaches and vision changes similar to a brain tumor, yet there isn’t a true mass forming from tumor cells. The other terms don’t fit: recurrent means something happening again, semilunar describes a crescent shape, and synapse is a neural junction. Hence, the term that describes a condition not being a true tumor is pseudotumor.
