Summary of Foot & Ankle Masses
HIDEInteractive Transcript

This concludes our discussion
0:03
of foot and ankle masses.
0:06
I've tried to show you masses that are
0:09
specifically related to the lower extremity.
0:11
For instance, the synovial sarcoma.
0:13
Unfortunately, it loves, it loves
0:16
the foot and the lower extremity.
0:18
I've also shown you some lesions that
0:21
don't typically occur in the lower
0:22
extremity, like giant cell tumor.
0:24
But I started this lecture with a large,
0:27
bizarre, cystic mass of the great toe
0:30
with a pretty broad differential
0:32
diagnosis that we eventually winnowed down and
0:35
we came up with the diagnosis of a ganglion,
0:38
eventually included in our differential.
0:40
I believe that was our second choice and
0:43
histologically, it turned out to be a ganglion.
0:45
And then we went all the way through a
0:47
series of lesions, some with iron, some with
0:49
hemosiderin, some with fibrous tissue,
0:52
some systic, and we concluded, again with another
0:55
cystic mass, the one at the very end was
0:57
more focal, isolated to the peroneus brevis.
1:00
So I hope I've given you an approach to
1:03
diagnosing masses that occur in the foot,
1:06
that are unique to the foot, and I don't
1:08
think it gets any more unique than plantar
1:10
fibromatosis or Ledderhose's disease.
1:13
I hope you've enjoyed this session
1:15
that we've shared together.
1:16
Good luck. Thanks.
