Nasal furunculosis

Nasal furunculosis, an infection localized to the hair-bearing nasal vestibule, frequently emerges as a diagnostic and management challenge in primary care settings. Predominantly instigated by Staphylococcus aureus, this condition serves as a cautionary tale for complications that can escalate when initial symptoms are underestimated or improperly treated. From a seemingly trivial issue such as nose-picking to complex predisposing factors like immunodeficiency, the genesis of nasal furunculosis is multifaceted. Clinicians must not only be adept at recognizing the hallmark features, often exemplified by the "Rudolph Sign," but also be vigilant for signs that indicate progression toward potentially life-threatening complications such as cavernous sinus thrombosis.

The objective of this guide is to provide an in-depth, evidence-based overview for primary care clinicians. This guide aims to equip healthcare providers with the essential knowledge required for the effective diagnosis, treatment, and management of nasal furunculosis, with a particular focus on clinical features, management strategies, and red flags that necessitate immediate referral to secondary care.
