Gastrointestinal polyposis with associated cutaneous manifestations

Area of Science:

• Gastroenterology
• Dermatology
• Genetics

Background:

• Cutaneous findings frequently indicate underlying gastrointestinal disorders, sometimes as the initial symptom.
• Syndromes like Lynch syndrome and Peutz-Jeghers syndrome present with variable expressivity, complicating early diagnosis.
• Skin manifestations serve as a recognizable indicator for various gastrointestinal syndromes, some linked to malignancy.

Purpose of the Study:

• To review key gastrointestinal syndromes with cutaneous manifestations.
• To highlight the role of skin findings in early detection and management.
• To discuss genetic, clinical, and pathological aspects of these syndromes.

Main Methods:

• Literature review focusing on hereditary and non-hereditary gastrointestinal polyposis syndromes.
• Analysis of clinical, epidemiological, genetic, and pathological findings.
• Emphasis on syndromes including Lynch syndrome, familial adenomatous polyposis, Peutz-Jeghers syndrome, PTEN hamartoma syndromes, and Cronkhite-Canada syndrome.

Main Results:

• Several gastrointestinal syndromes, including Lynch syndrome and hamartomatous polyposis syndromes, are associated with distinct skin findings.
• These syndromes, often inherited in an autosomal dominant manner, can manifest with benign or premalignant lesions.
• Early identification of cutaneous markers is crucial for timely screening and intervention.

Conclusions:

• Cutaneous manifestations are vital clues for diagnosing underlying gastrointestinal disorders.
• Screening based on dermatological signs can significantly decrease morbidity and mortality.
• Understanding these associations facilitates early detection in patients and their families.
