Metastatic tumor of the orbit is sufficiently uncommon to warrant the report of a case. Primary orbital sarcomas occur with such relative frequency that one may readily overlook the possibility of any orbital tumor being secondary to a primary growth elsewhere. Obviously, the great majority of orbital malignant growths are primary and are of mesoblastic origin, but Morax1 collected six cases of metastatic sarcomas of the orbit. Bride2 also reported one, metastasized from cancer of the thigh, bringing the total to seven. One of Morax's series (Bietti) probably had its origin from a tumor of the right suprarenal gland. Unless an autopsy is done the primary growth may never be discovered, in the absence of history of a previous malignant growth or of evidence of cancer elsewhere in the body, as illustrated by my case.
