Glomus tumor of the lateral aspect of the knee joint.
BACKGROUND
We report a rare case of glomus tumor that occurred in the lateral joint of the knee. A 54-year-old man was referred to us with a 3-year history of lateral pain in the left knee and the diagnosis of lateral meniscus injury. Physical examination revealed a small trigger point localized just on the lateral joint space. Magnetic resonance imaging (MRI) showed a very small round mass in the subcutaneous tissue at the level of the lateral joint space.


METHODS
Excisional biopsy was performed, and the histology was characteristic of a glomus tumor. The patient was asymptomatic immediately after the operation. At the 3-year follow-up after the operation, no recurrence was seen.
