A zygomatic mass is a rare occurrence, We describe a 52-year-old man w
ith a zygomatic arch mass and a recent history of facial trauma, Findi
ngs on a computed tomographic scan of the facial bones were interprete
d as callus formation, consistent with fracture of the zygomatic arch,
The level of the prostate-specific antigen was increased to 62.3 ng/m
L, and a biopsy of a nodular prostate specimen revealed adenocarcinoma
(Gleason sum, 3 + 4 = 7), Because the laboratory data, history, and f
indings on physical examination did not correlate, we suspected a tumo
r metastatic to the facial bones.
