Hamartomatous polyp of the gallbladder with an associated choledochal cyst

Ahamartomatous polyp is an extremely rare polypoidal lesion of the gallbladder, with the first case having been reported in 1998.¹ To the best of our knowledge, fewer than 10 hamartomatous gallbladder polyps have been reported in patients with Peutz-Jeghers syndrome (PJS). The largest series evaluating extraintestinal polyps in patients with PJS revealed 3 patients with a gallbladder polyp among 72 patients with 1 pathologically proven hamartomatous polyp.² Hamartomatous gallbladder polyps are thus rare in patients with PJS, and as mentioned before, to the best of our knowledge, it has not been reported before in a patient without PJS. Another interesting finding in this case was the association of a type 1 choledochal cyst with the hamartomatous gallbladder polyp.
