Gastrointestinal Pyogenic Granuloma (Lobular Capillary Hemangioma): An Underrecognized Entity Causing Iron Deficiency...

Area of Science:

• Gastroenterology
• Pathology
• Oncology

Background:

• Pyogenic granuloma (PG), or lobular capillary hemangioma, is a benign vascular tumor typically found in the skin or oral mucosa.
• Gastrointestinal (GI) PG is rare but poses a significant bleeding risk if not managed.
• Accurate diagnosis is crucial for appropriate patient management.

Purpose of the Study:

• To describe the clinical, endoscopic, and histologic features of four GI PG cases.
• To review the literature and summarize all reported cases of GI PG.
• To discuss the potential underdiagnosis of GI PG and its clinical implications.

Main Methods:

• Case series analysis of four patients with GI PG.
• Comprehensive literature review of previously reported GI PG cases.
• Clinical, endoscopic, and histopathological data compilation and analysis.

Main Results:

• Four cases of GI PG were identified and analyzed.
• Literature review identified additional reported cases, contributing to a cumulative understanding.
• Findings suggest GI PG may be underrecognized, potentially leading to missed diagnoses.

Conclusions:

• GI PG, though rare, should be considered in the differential diagnosis of GI bleeding.
• Clinicians must be aware of PG's propensity to bleed, especially during procedures.
• Improved recognition and diagnosis are essential for managing anemia and bleeding associated with GI PG.
