Neuroembolization of metastatic Merkel cell cancer to the face for treatment of Kasabach-Merritt syndrome.

Kasabach-Merritt syndrome is defined as a consumptive thrombocytopenia in the presence of a highly vascular tumor. Multiple treatment options, including transarterial embolization, have been described. We demonstrate that transarterial embolization is a viable option in the treatment of a rapidly progressive and debilitating Merkel cell tumor metastasizing to the head and neck presenting with Kasabach-Merritt syndrome.
