Which of the following terms is associated with the prefix "ichthy/o"?

The prefix "ichthy/o" is derived from the Greek word "ichthys," which means "fish." In medical terminology, it specifically relates to conditions associated with dryness or scaling of the skin, akin to the appearance of fish scales. When applied to dermatological contexts, the term most commonly refers to ichthyosis, a condition characterized by the presence of dry and scaly skin. Therefore, "dry/scaly" accurately describes the term associated with the prefix "ichthy/o," making it the correct answer.

The other terms—yellow, white, and hard—do not correlate with the prefix "ichthy/o" or its established meanings in medical coding or terminologies. Yellow is often referenced with "jaun/o," white typically relates to "leuk/o," and hard can be described by terms like "scler/o." These associations further substantiate the focus of "ichthy/o" on dryness and scaling rather than color or texture variations.
