INCE HALPERT and Patzer3 first described S the retinal anlage tumor in the maxilla, there have been several reports of these tumors in the jaw bones. I n 1956, Eaton and Ferguson2 described a similar lesion in the epididymis, and Blanc et al.1 reported one over the deltoid area. We believe this to be the second case in the shoulder region.

Embedded in it were blood vessels and a few small bundles of nerve fibers. I n some areas, there was evidence of recent and past hemorrhage, with foci of xanthomatous reaction and deposition of hemosiderin. I n addition, there were foci of infiltration by lymphocytes, mainly perivascularly, and occasional neutrophils. A solitary foreign body granuloma was present. These inflammatory reactions could be accounted for by the scarifications on the over-
