[Cutaneous angiosarcoma clinically presenting as Quincke's edema]

We report a case of a 75-year-old man with facial edema that also affected the periorbital area who was admitted to the hospital with the suspected diagnosis of Quincke's edema. The diagnosis of cutaneous angiosarcoma was made by microscopic examination and immunohistochemical staining. Chemotherapy was initially initiated because the angiosarcoma was unresectable and the radiation situation was difficult. Therapy has to be switched to second and third line therapy due to disease progression. The case illustrates the complexity of diagnosis and therapy in patients with cutaneous angiosarcoma.
