Pediatric Intranasal Lobular Capillary Hemangioma: A Scoping Review and Multimedia Case Presentation.

Study design: Systematic, scoping literature review and case presentation.

Objective: The goal of this study is to review current literature on management trends and outcomes of pediatric intranasal lobular capillary hemangioma (ILCH).

Case presentation: A 14-year-old male patient presented with a 15-month history of unilateral epistaxis, nasal congestion, and mouth breathing. Further workup revealed a pale nasal mass obstructing the right nasal cavity. The patient was successfully treated using a minimally invasive endoscopic endonasal approach for mass resection and nasal floor free mucosal graft for septal reconstruction.

Methods: Independent queries of the PubMed Central, MEDLINE, and Bookshelf databases were performed; articles from 1990 to 2023 were abstracted. All studies that described pediatric ILCH using the Boolean method and relevant search term combinations, including "Intranasal," "Lobular capillary hemangioma," "Pyogenic granuloma," "Pediatric," "Outcome," and "Management," were collected for subsequent analysis.

Results: A total of 407 relevant unique articles were identified for analysis. Of these, 19 articles were deemed appropriate for inclusion in this literature review. Twenty-two pediatric ILCH cases were identified with a mean age at diagnosis of 10.5 years. The majority of cases occurred in males and presented with recurrent epistaxis and nasal obstruction. Most lesions originated from the anterior nasal septum and were resected using an endoscopic endonasal approach with no recurrence at last follow-up.

Conclusions: Pediatric ILCH, a benign vascular neoplasm, often presents with unilateral nasal obstruction and severe, refractory epistaxis. This comprehensive review aims to highlight the importance of including this lesion in the differential diagnosis for unilateral nasal obstruction and epistaxis in young children.
