Abstract

Objective: The aim of this study was to evaluate the clinical features and functional results of patientswith parosteal lipomas.Methods: A total of 12 patients (8 females and 4 males; mean age: 45 (10e62) years) with parosteallipomas who were treated between April 1986 and April 2014, were included into the study. The medicalrecords of the patients were reviewed to analyze the clinical features and functional results of thepatients.Results: Of the 12 lipomas, 5 were localized in the proximal arm, 4 in the forearm, 1 in the distal arm, 1 inthe distal thigh and 1 in the distal tibia. All patients presented with a progressive, slow-growing massthat was associated with thumb extension weakness in 1 case, and brachialgia-like symptoms in 1 case.Plain radiographs showed a juxtacortical mass in all cases and irregular ossiŞcation in 3 cases. In all cases,marginal excision was performed and no clinical recurrence was observed after a mean follow-up of 16months.Conclusion: Parosteal lipomas are uncommon tumors that can be diagnosed with their characteristicradiological features. Parosteal lipomas occurring in the proximal radius may easily cause paralysis of theposterior interosseous nerve or muscle weakness.Level of Evidence: Level IV, Therapeutic study.
