A
neoplasm of the
peripheral nerves can be obscured, especially during the early phase. The authors
report a
patient with
sciatic nerve leiomyosarcoma. The
patient's presentation and initial management are unique. A 51-year-old man with clinical manifestations of
von Recklinghausen's disease reported
numbness and weakness of the left
leg for one and a half years. The symptoms gradually progressed. The symptoms were consistent with
peripheral neuritis. The
patient developed foot drop one month before coming to our service. Two episodes of
biopsy confirmed
leiomyosarcoma. A long, large
sciatic nerve leiomyosarcoma was found intra-operatively, positioned from the upper
thigh to the point where the
tibial nerve passes beneath the upper margin of the
soleus muscle. Surgical resection was done and confirmed the
diagnosis. Decreased
sensation was still intact after resection.
