Clinical features of soft tissue masses that require urgent investigation
| Increasing size |
| Size greater than 5 cm (ie, golf-ball size) |
| Deeper-lying mass (deep to fascia) |
| Firmer than surrounding tissue |
| Patient has potential risk factors (previous radiotherapy, chronic lymphedema, inherited syndrome such as Gardner syndrome, Li-Fraumeni syndrome, and von Recklinghausen disease) |
| Local symptoms and signs of infiltration |
| With or without pain (large painless lumps should raise concern) |
| The greater the number of clinical features, the greater the risk of malignancy. |
