Primary malignant mesenchymal colorectal tumours, representing a small fraction of soft tissue sarcomas, are characterised by predominance of gastrointestinal stromal tumour (GIST). After the GIST concept has been implemented in the diagnostics, the incidence of registered leiomyosarcomas has markedly decreased.
