Area of Science:

Otolaryngology
Surgical Pathology
Oncology

Background:

Liposarcoma of the temporal bone is an exceptionally rare malignancy.
This report presents the third documented case, highlighting the diagnostic and therapeutic challenges.

Observation:

A 69-year-old male presented with otalgia, otorrhea, and dizziness.
A history of cholesteatoma and prior tympanoplasty was noted.
Otoscopy revealed attic debris, leading to surgery for suspected recurrent cholesteatoma.

Findings:

Postoperative pathology confirmed a well-differentiated liposarcoma.
A subsequent palliative resection of the liposarcoma was performed.
The patient remained disease-free with no local recurrence or distant metastasis for 24 months.

Implications:

The favorable outcome suggests that the histological subtype of temporal bone liposarcoma may influence prognosis.
This case underscores the importance of thorough pathological examination for unexpected findings in temporal bone surgery.
Further research into the behavior and optimal management of temporal bone liposarcomas is warranted.
