[Mature teratoma of the auricle in children: a case report]
Insights
A pediatric patient presented with a growing left auricle mass, diagnosed via CT scan as a lipoma. This benign tumor required surgical removal due to its size and compression effects.
Area of Science:
- Pediatric Otolaryngology
- Diagnostic Imaging
- Surgical Pathology
Background:
- Congenital auricle masses can present diagnostic challenges in infants.
- Early detection and accurate diagnosis are crucial for appropriate management.
Observation:
- A 4-month-old female infant presented with a gradually enlarging mass on the left auricle since birth.
- Physical examination revealed a 5 cm×4 cm soft, flexible tumor compressing the upper auricle.
- The external auditory canal remained unobstructed with no signs of inflammation.
Findings:
- CT imaging demonstrated a fat-density mass in the left outer auricle, consistent with a lipoma (CT values 22-147 HU).
- High-resolution CT (HRCT) scans of the mastoid, middle ear, and inner ear showed no abnormalities.
Implications:
- Lipomas of the auricle, though rare, require accurate diagnosis to differentiate from other pediatric masses.
- Surgical excision is typically curative for symptomatic or cosmetically concerning auricle lipomas.
- This case highlights the importance of advanced imaging in characterizing pediatric auricular lesions.
Abstract:
The patient, female, 4 months and 8 days years old, was admitted to the hospital due to the left auricle mass. When the child was born, the parent found that there was a soybean-sized mass in the left auricle, without special treatment, and then gradually increased. Examination: A 5 cm×4 cm size tumor was visible above the left auricle. It was soft and flexible. The upper edge of the left auricle was deformed by the compression of the tumor. The external auditory canal was unobstructed, and the skin was smooth without redness or swelling. Auxiliary examination, CT showed: ①Left outer auricle fat-like density mass, CT value 22-147 HU, consider lipoma; ②Both sides of mastoid, middle ear, inner ear HRCT scan showed no abnormalities.
