Leiomyosarcoma of the oesophagus is a malignant tumor that originates from smooth muscle cells. The filiation between oesophageal leiomyoma and leiomyosarcoma is controversial, with few cases reported in literature. The authors describe un uncommon situation with the simultaneous presence of a leiomyoma and a leiomyosarcoma of the oesophagus in a 75 year-old man, which have been successfully treated with surgical resection. It could probably be a case of a malignant transformation of a previous pre-existing multiple non-confluent leiomyoma.
