Description
Sui-jiang Wang and three co-authors wrote a 2026 case report on a rare blue growth under a fingernail. A 51-year-old woman had blue-grey color and splitting on her left little finger for 22 years. The color began as a small spot near the base of the nail and spread slowly toward the nail root.
Growths of this kind, called blue nevi, are clusters of pigment cells in the skin. Under a nail they are rare: only 32 cases had been reported in English, and none on a little finger. Most cases are in women and on the hand, often the thumb. The report walks through the exam and the slow course of the case. It adds a new site to the known map of this rare growth and helps doctors judge odd nail color.
