Lipoma of the Neck.

Background: Lipomas are benign formations with the mesenchymal origin, which are found in the head and neck region in a very small percentage of cases. In these cases, they usually occur in the posterior neck and usually grow very slowly without causing complaints. However, when they cover the front of the neck, it is necessary to confirm the adipose origin of a tumour and to exclude the connection with the thyroid gland. Although in principle, lipomas are benign, there are three more unfavourable possibilities of 1) malignancy of lipomas, 2) the occurrence of de novo liposarcomas or 3) the association of lipomas with other tumours, such as retinoblastoma.

Case Report: We present a 74-year-old woman with a painless subcutaneous formation in the neck. A Fine Needle Aspiration Biopsy (FNA) was performed, with the conclusion of the cytological result for lipoma. Surgical removal was planned under general anaesthesia.

Conclusion: Usually, lipomas do not require surgery, but when they engage muscles they become indicative of surgical treatment.
