Pilomatrixoma of earlobe

Area of Science:

• Dermatology
• Pediatric Oncology
• Pathology

Background:

• Pilomatrixomas are rare benign skin neoplasms originating from hair matrix cells.
• They are uncommon in pediatric populations and often present diagnostic challenges.
• Preoperative misdiagnosis is frequent due to varied clinical presentations.

Observation:

• A two-year-old female presented with a lesion on her earlobe.
• The lesion's location in the earlobe was atypical for pilomatrixomas.
• Clinical examination and subsequent biopsy confirmed pilomatrixoma.

Findings:

• The pilomatrixoma was successfully treated with simple enucleation.
• Post-operative follow-up for two years showed no signs of recurrence.
• This case underscores the possibility of pilomatrixomas in unusual pediatric locations.

Implications:

• Highlights the importance of considering pilomatrixomas in pediatric differential diagnoses, even with unusual localizations.
• Suggests that simple enucleation may be an effective treatment for pediatric earlobe pilomatrixomas.
• Emphasizes the need for increased awareness among clinicians regarding rare presentations of common pediatric skin lesions.
