Insights
Peutz-Jeghers syndrome, a genetic disorder, causes hamartomatous polyps and skin hyperpigmentation. Early diagnosis and endoscopic removal of polyps are crucial due to high malignancy risk.
Area of Science:
- Gastroenterology
- Genetics
- Oncology
Context:
- Peutz-Jeghers syndrome (PJS) is an inherited disorder.
- Characterized by hamartomatous polyps and mucocutaneous hyperpigmentation.
- PJS significantly increases cancer risk.
Purpose:
- To present findings from 16 Peutz-Jeghers syndrome cases.
- To highlight common clinical presentations and polyp characteristics.
- To emphasize the importance of long-term surveillance and management.
Summary:
- This study analyzed 16 Peutz-Jeghers syndrome cases, noting a higher prevalence in females.
- Gastrointestinal complaints were most common, with hamartomatous polyps distributed throughout the GI tract.
- Endoscopic polypectomy is recommended for treatment, alongside regular radiologic, endoscopic, and histologic follow-up due to malignancy risk.
Impact:
- Informs clinical practice regarding PJS diagnosis and management.
- Underscores the need for vigilant screening in PJS patients.
- Contributes to understanding the natural history and oncologic risks of PJS.
Abstract:
Peutz-Jeghers syndrome is an autonomic dominant disease characterized by hamartomatous polyps and mucocutaneous hyperpigmentation. We present 16 cases; females were more affected. The most common presenting complaints were of gastrointestinal tract. All polyps found were hamartomatous with general distribution through gastrointestinal tract. Endoscopic polypectomy should be carried out for treatment. Radiologic, endoscopic and histologic studies should be conducted for long-term follow-up, because of high risk of malignancy.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
