Insights
Peutz-Jeghers syndrome, an inherited condition, involves gastrointestinal hamartomatous polyps and melanin spots. This case highlights the risk of adenocarcinoma developing within these hamartomatous polyps, specifically in the jejunum.
Area of Science:
- Gastroenterology
- Oncology
- Genetics
Background:
- Peutz-Jeghers syndrome (PJS) is an autosomal dominant disorder.
- PJS is characterized by hamartomatous polyps in the GI tract and mucocutaneous melanin spots.
- While PJS polyps are typically benign, there's an established association with gastrointestinal cancers.
Abstract:
Peutz-Jeghers syndrome is characterized by hamartomatous polyps in the gastrointestinal tract associated with mucocutaneous melanin spots; the condition is inherited in an autosomic dominant fashion. Although the hamartomatous polyps are not regarded as malignant, there is an association between the Peutz-Jeghers syndrome and the development of carcinomas of the gastrointestinal tract. Similarly, there is an increasing evidence suggesting that hamartomas can give rise to adenocarcinomas. We present a patient with Peutz-Jeghers syndrome who developed an adenocarcinoma in an hamartomatous jejunal polyp.
