title: Classification of benign fatty tumours of the upper limb.
abstract: In this paper, the authors offer a classification of benign fatty tumours of the upper limb. There are three histologically distinct types of fat cells: immature fat cells which give rise to lipoblastomas, mature brown fat cells which give rise to hibernomas and mature white fat cells which give rise to lipomas. Lipomas are the most common and they are sub-classified according to the anatomic site of fat cells into dermal, subcutaneous and sub-fascial lipomas; or tumours directly related to muscle, bone, synovium or nerve. Finally, the authors review 67 patients with benign fatty tumours of the upper limb and provide clinical examples of these tumours including their characteristic histological and radiological features.
