Infiltration der Schädelkalotte durch ein dedifferenziertes kutanes Leiomyosarkom

We present a brief report of an 81-year-old man with a pretreated leiomyosarcoma of the skull. Histologically the diagnosis of a dedifferentiated cutaneous leiomyosarcoma with an infiltration of the skull was confirmed. In an interdisciplinary approach together with the University Clinic for Neurosurgery, complete removal of the tumour was performed. Cutaneous leiomyosarcoma are rare tumors of the skin and typically present as slowly growing erythematosus nodes. Because of the risk of metastatic spread, complete micrographically confirmed resection is necessary.
