Overview

Peutz-Jeghers syndrome must be differentiated from other diseases that cause hamartomatous polyps and mucocutaneous pigmentation, such as Cowden syndrome, Bannayan–Riley–Ruvalcaba syndrome, juvenile polyposis, and McCune-Albright syndrome.

Differentiating Peutz-Jeghers Syndrome from other Diseases

Peutz-Jeghers syndrome must be differentiated from the following diseases:[1][2]
