Abstract
Introduction
Primary soft tissue sarcomas of the extremities are uncommon. Many such lesions will present to specialists in other clinics such as specialist Hand or Foot and Ankle clinics. Many are of a small size at presentation and may appear to be alternate, more common pathology.
Methods
We collected data from all those patients with acral soft tissues sarcomas and referred to the Oxford Sarcoma Service, Nuffield Orthopaedic Centre, Oxford over a thirteen year period from 1997 – 2010. Data were collected regarding the primary suspected diagnosis, the final diagnosis, the referral route and whether patients had undergone previous inadvertent excision.
Results
38 patients were treated (24 foot, 14 hand tumours). The commonest histological subtype was synovial sarcoma in the foot group, and leiomyosarcoma in the hand group. 25 of the 38 patients had a lesion of less than 5cm at presentation. For those patients in whom a wide excision was performed 50% underwent complex plastic surgical reconstruction.
Discussion
This study shows that 30% of patients with acral tumours required further surgery due to previous inadequate/inadvertent excision. 5cm as a benchmark for specialist referral should not be applied to lesions in the hand or feet and we recommend the use of the “marble rule” i.e. any lesion the size of a marble should be referred urgently and no patient should undergo surgery without imaging.
