Summary
Hibernomas, rare benign tumors resembling brown fat, can occur in the head and neck. This case highlights a cervical hibernoma, emphasizing its consideration in neck mass differentials.
Area of Science:
- Oncology
- Pathology
- Surgical Anatomy
Background:
- Hibernomas are uncommon benign neoplasms.
- They originate from brown adipose tissue.
- Head and neck hibernomas are exceptionally rare.
Observation:
- A 54-year-old female presented with a large, asymptomatic lateral neck mass.
- Imaging and fine-needle aspiration suggested hibernoma, with liposarcoma as a differential diagnosis.
- Surgical resection was performed for definitive diagnosis and treatment.
Findings:
- Postoperative analysis confirmed the cervical mass as a hibernoma.
- The tumor exhibited characteristic gross and microscopic features of hibernoma.
- Complete resection was achieved.
Implications:
- This case expands the known anatomical sites for hibernoma presentation.
- It underscores the importance of including hibernoma in the differential diagnosis of neck masses.
- Awareness aids in accurate preoperative assessment and surgical planning for soft-tissue tumors.
