Summary
This case report details a rare inflammatory myofibroblastic tumor (IMT) in a patient's ear lobule. Surgical removal was successful, with no recurrence observed, highlighting effective management of this auricular tumor.
Area of Science:
- Dermatology
- Pathology
- Surgical Oncology
Background:
- Inflammatory myofibroblastic tumors (IMTs) are rare neoplasms with unpredictable behavior.
- IMTs typically occur in the abdomen or pelvis, but can arise in any location.
- External ear involvement by IMT is exceptionally uncommon.
Observation:
- A 50-year-old woman presented with a slow-growing, asymptomatic, wart-like mass on her ear lobule.
- The mass was incidentally discovered a year prior to a minor ear lobule trauma.
- Histopathology revealed a spindle cell proliferation with lymphoplasmacytic infiltration, consistent with IMT.
Findings:
- The patient underwent surgical excision and primary closure of the ear lobule mass.
- Post-operative histopathology confirmed the diagnosis of inflammatory myofibroblastic tumor.
- No evidence of tumor recurrence was noted at the 6-month follow-up.
Implications:
- This is the first reported case of an IMT originating in the external ear.
- Auricular IMTs may present with a non-aggressive clinical course.
- Complete surgical excision appears to be an effective treatment modality for auricular IMT.
