# Facial Cellulitis and Skin Abscess: A Case of a Simple Bone Cyst in the Mandibular Bone

## TL;DR

A case of facial infection caused by a bone cyst in the jaw, not dental decay, highlights the importance of proper imaging for accurate diagnosis.

## Contribution

Reports a rare case of odontogenic cellulitis caused by a simple bone cyst without dental caries.

## Key findings

- Facial cellulitis and skin abscess were caused by a simple bone cyst in the mandible.
- Proper imaging was essential for diagnosing the infection's origin.
- The case occurred without dental caries, challenging typical diagnostic assumptions.

## Abstract

Cellulitis, abscess, or both are among the most common skin and soft tissue infections. Typically, cellulitis arises due to bacterial penetration through breaches in the skin's protective barrier. However, in cases of facial cellulitis, it is necessary to consider not only the breakdown of the skin barrier but also to differentiate odontogenic cellulitis. A prompt and accurate diagnosis of facial infections stemming from dental issues, coupled with the administration of antibiotics and dental interventions, played a crucial role in resolving this condition. Odontogenic cellulitis often develops as a result of dental caries. However, we experienced a case of odontogenic cellulitis and skin abscess occurring due to a simple bone cyst in the mandible, even in the absence of dental caries. Proper imaging examinations are crucial for diagnosis.
