# Oral neurovascular hamartoma: An independent entity not associated to rhabdoid tumors

## TL;DR

This paper describes a rare oral condition called neurovascular hamartoma in a child and clarifies it is not linked to rhabdoid tumors.

## Contribution

The paper establishes that oral neurovascular hamartoma is an independent, benign entity unrelated to rhabdoid tumors.

## Key findings

- A 6-year-old patient presented with asymptomatic papular lesions diagnosed as oral neurovascular hamartoma.
- Histopathological analysis confirmed the diagnosis and ruled out rhabdoid tumor association.
- The condition is benign and distinct from other oral lesions, requiring proper diagnosis for accurate treatment.

## Abstract

Oral cavity neurovascular hamartomas are extremely rare, with unknown prevalence, possibly due to their rarity, unrecognition or under-report. We describe a 6-year-old female patient with this uncommon lesion and review existing literature.

The patient presented with asymptomatic papular lesions, which increased in size and number since birth. First, one of the papular lesions on the lower lip was excised for histopathologic study, revealing the unexpected diagnosis.

Oral neurovascular hamartomas are unusual and challenging lesions to diagnose. Even though their benign nature, the need of differential diagnosis with other oral lesions makes necessary their histopathological study and confirmation.

Even oral neurovascular hamartoma is an uncommon entity, surgeons and oral pathologist should be aware of this entity in order to distinguish it from other lesions. Besides, it is not clearly related to rhabdoid tumors as other authors have stablished previously, being an independent entity with great prognosis for the patient.

Key words:Oral neurovascular hamartoma, benign tumors, pediatric age masses, rhabdoid tumors.
