Lipomatosis of the neck: Case report and literature review☆

Summary 

Lipomas are common benign tumors of the head and neck that are discrete and encapsulated. Lipomatosis, however, is a more diffuse fatty tissue growth rarely found in the head and neck. A 2.5-year-old female presented with a painless, right supraclavicular mass. Radiologic evaluation revealed extension into the anterior mediastinum. Incisional biopsy and histology were consistent with lipomatosis. The lesion was not excised and at 2 years follow-up the child remains asymptomatic with no enlargement on imaging. Conservative nonoperative management should be considered with asymptomatic disease in which the morbidity and mortality of excision may be high.
