Are pigmented tastebuds a variation of normal? i have about 5 med-brown ones located on the right side of the tip of my tongue, but cant find information online. noticed about a month and a half ago. 35f white (mediterranean background).

Normal Variation: Pigmented fungiform papillae of the tongue are a benign condition that is characterized by pigmentation involving the fungiform papillae. It is more common in medium/dark-skinned individuals, and most reported cases are adults between the second and third decades. There is no underlying medical condition associated with this finding.
