Soft-tissue tumours (STT) are a heterogeneous group of benign and malignant diseases accounting for <4% of all tumours in adults and <8% of all tumours in children. Soft-tissue sarcomas rare malignant tumours derived from mesenchymal cells at all body sites. These rare tumours comprise approximately 1% of all newly diagnosed cancers. The incidence of soft tissue tumours is approximately 2000 cases per annum in the UK.
Patients may present with a painful or painless swelling that is growing insidiously. Almost 50% arise in the lower limbs (most commonly the adductor compartment of the thigh) and the median age for presentation is 65 years. Concern at to the biological activity of a lesion should arise if the size is >5cm, it is painful, deep to fascia, increasing in size, or recurrence of a previously excised lesion. Each of these five characteristics corresponds to an approximately 20% risk of malignancy. Any lesion presenting with features that are suggestive of STT require referral to specialist centres, where appropriate evaluation and staging will take place.
