The phrase "a special diffusion" is correct and usable in written English.
It can be used in contexts related to the spread or distribution of something unique or specific, such as ideas, substances, or technologies.
Example: "The researchers conducted a study on a special diffusion of the new vaccine in urban areas."
Alternatives: "a unique distribution" or "a distinct spread".
