Extensive Pelvic Venous Malformation in a Child With Recurrent Hematochezia

Area of Science:

• Vascular Medicine
• Gastroenterology
• Dermatology

Background:

• Rectal bleeding is a common symptom with diverse etiologies.
• Cutaneous vascular malformations are relatively common but can be associated with systemic conditions.
• The link between unexplained rectal bleeding and cutaneous vascular malformations is often overlooked.

Purpose of the Study:

• To highlight the association between unexplained rectal bleeding and cutaneous vascular malformations.
• To emphasize the importance of considering combined vascular malformations in patients presenting with both conditions.
• To advocate for a structured diagnostic pathway for these patients.

Main Methods:

• Review of clinical cases presenting with both unexplained rectal bleeding and cutaneous vascular malformations.
• Discussion of diagnostic challenges and potential pitfalls.
• Emphasis on the utility of a multidisciplinary team approach.

Main Results:

• The presence of a cutaneous vascular malformation in patients with unexplained rectal bleeding should prompt investigation for underlying combined vascular malformations.
• Delayed diagnosis can result from isolated assessment of each symptom.
• Integrated diagnostic strategies improve patient outcomes.

Conclusions:

• Combined vascular malformations can manifest with both gastrointestinal and cutaneous symptoms.
• A high index of suspicion and a coordinated, multidisciplinary approach are crucial for timely diagnosis.
• Prompt recognition and management prevent misdiagnosis and ensure optimal patient care.
