title: Malignant degeneration in Madelung's disease (benign lipomatosis of the neck): case report.
abstract: Although not a common condition, benign lipomatosis of the neck (Madelung's disease) is well documented in the literature and to date we have failed to trace any reference to malignant change developing in this tissue. We wish therefore to report the case of a patient with benign lipomatosis of the neck in which malignant degeneration appeared after an interval of 6 years and in which this transformation from a benign to a malignant lesion was verified by histological examination.
