Multiple Pyogenic Granulomas in the External Auditory Canal

Area of Science:

• Otolaryngology
• Dermatology
• Pathology

Background:

• Pyogenic granuloma (PG) is a common benign vascular tumor, typically affecting the skin and mucous membranes.
• While often solitary, multiple PGs are rare, and their occurrence in the external auditory canal (EAC) is exceptionally uncommon.
• The head and neck region accounts for one-third of PG cases, yet the EAC remains a rare site.

Purpose of the Study:

• To report a rare case of multiple pyogenic granulomas in the external auditory canal.
• To review existing literature on pyogenic granulomas in the external auditory canal.
• To discuss clinical suspicion, diagnosis, and management of this rare presentation.

Main Methods:

• Case report of a 36-year-old male with multiple PGs in the EAC.
• Comprehensive literature review on pyogenic granulomas, focusing on external auditory canal involvement.
• Discussion of clinical presentation, potential etiologies, and treatment strategies.

Main Results:

• A unique case of multiple pyogenic granulomas was identified in the external auditory canal of a 36-year-old man.
• The literature review confirmed the rarity of multiple PGs within the EAC.
• Clinical suspicion for EAC PGs should consider trauma, hormonal changes, drug administration, rapid growth, and bleeding.

Conclusions:

• Multiple pyogenic granulomas in the external auditory canal represent a rare clinical variation.
• Surgical excision down to the perichondrium is recommended for symptomatic PGs to prevent recurrence.
• Early diagnosis and appropriate management are crucial for favorable outcomes in these rare cases.
