Turrets exostosis are extremely rare to occur. Benign bony outgrowths from the dorsum of the phalanges following trauma are termed Turrets exostosis. We report an unusual case of Turrets exostosis of the fourth finger with no preceding trauma which has never been reported before. A 50-year-old female patient presented to us with a bony swelling on the dorsum of the fourth finger of her right hand in one year. The swelling was dormant initially and started to progress in size since three months leading to pain, restriction of movements and deformity of the finger. Turrets exostosis are very rare to occur. A preceding history of trauma is not necessary for it to occur as described in the literature. Surgical excision yields good results and is indicated when the bony mass causes a progressive deformity of the finger and restriction of movements of the finger.
