Description
Parsa Nilchian and co-authors report a rare tumor hiding in a leg nerve, in a 2025 case study. A 70-year-old woman with multiple myeloma came in with right leg pain and a suspected nerve sheath tumor of the tibial nerve. Scans showed a dark lesion behind the knee.
Surgery began, but a quick frozen tissue check revealed a plasma cell tumor with a high growth rate, not a sheath tumor. The mass wrapped and bled into the nerve so deeply that removal was halted. She then received five radiation sessions and three courses of an antibody drug, continuing as an outpatient without complications. The authors urge biopsy during such surgery, since scans alone can misname these growths.
