Ulcus cruris venosum und ulzerierte Malignome der Unterschenkel - Differenzialdiagnostische Überlegungen am Beispiel eines ulzerierten Leiomyosarkoms

In this case report a patient is presented with an extensive ulcerous cutaneous leiomyosarcoma which developed at the front of the right lower leg within a few months. This ulceration initially appeared as a venous ulceration and, accordingly an outpatient therapy was initiated. When the patient was admitted to the hospital metastases were already present. Ulcerous malignant skin tumours of the lower legs may clinically imitate a venous ulceration and therefore may not be diagnosed in appropriate time. In our patient case history, clinical morphology as well as missing signs of chronic venous insufficiency led to the definite diagnosis by histopathological examination.
