Abstract

Background: Peutz-Jeghers syndrome (PJS) is an autosomal dominant inherited disorder, characterized
by intestinal hamartoma polyps in association with distinct patterns of skin and mucosal macular melanin
deposition. Patients with PJS have a 15-fold increased risk of developing bowel cancer compared to the
general population.

had an endoscopy in the gastrointestinal tract and histopathological examination of the colonic mucosa, no
abnormalities were found and no signs of malignancy were found on histopathological examination.
Conclusion: Result of histopathological examination showed an increase in the number of melanocytes
in the stratum basale with lined melanocytes. Based on histopathological examination in this patient more
leads to the diagnosis of PJS
