Recurrence: Sarcomas are soft tissue tumours and have differences in the rapidity of growth . Some of them slow growing, some are fast and some are very fast. Ssarcomas arising from skin related structures-like fibro sarcoma, liposarcoma, angiosarcoma etc. Are there. There is a need to get HIV also tested in fast spresding sarcomas as there is a particular type called kaposis sarcoma - with rapid growth rate.
