Osseous abnormalities produced by glomus tumors located in soft tissues of
the periungual region have been described. More rare is the location of a g
lomus tumor within bone, which usually is located in the phalanx of the fin
gers. However, to the authors' knowledge, there is no previous description
of a glomus tumor located in a periosteal location of a long bone. A 50-yea
r-old man with a glomus tumor in a periosteal location of the lower metaphy
sis of the femur without neoplastic erosion of the cortical surface is repo
rted. Magnetic resonance imaging and intraoperative ultrasonography were ne
eded to locate the lesion.
