[Angiolymphoid hyperplasia with eosinophilia].

Area of Science:

• Dermatology
• Pathology
• Vascular Biology

Background:

• Angiolymphoid hyperplasia with eosinophilia (HALE) is a rare benign vascular proliferation.
• Typically affects young female adults, presenting as skin or subcutaneous nodules.
• Etiology remains largely unknown, posing diagnostic challenges.

Observation:

• An 81-year-old male presented with a lesion affecting the entire ear auricle.
• Histological examination confirmed the diagnosis of HALE.
• The lesion exhibited spontaneous and complete regression within 2 months.

Findings:

• The case demonstrated a rare presentation of HALE in an elderly male.
• Histological confirmation was achieved through biopsy.
• Complete spontaneous regression occurred without recurrence after 1 year.

Implications:

• Spontaneous regression of HALE is possible, supporting a conservative management approach.
• Close patient monitoring for 3-6 months is recommended before considering surgical intervention.
• Distinguishing HALE from Kimura disease is crucial for appropriate diagnosis and management.
