Bone and Soft Tissue Tumours of the Foot and Ankle

Although „lumps and bumps“ are readily detected by clinical investigation due to shallow soft tissue layers, covering the foot, diagnosis is nevertheless considerably delayed (2to 3-fold compared to other body regions) [4]. This delay in establishing a timely diagnosis has usually to do with an underestimating these tumours as they are appearing as small masses. Small, well-demarcated and rounded soft tissue masses are erroneously considered as being simply benign or harmless, resp [5]. As a consequence, this assumption may lead to misdiagnosis and treatment failure. Fortunately, both delayed diagnosis and treatment do not deteriorate prognosis and overall survival because of the very slow pedal tumour growth rate (10 – 20fold reduced growth rate compared to the rest of the body) and the overall small tumour size [6].
