Glomus tumor and knee pain: A report of four cases

We present four cases of glomus tumors presenting as knee pain. All cases were treated by surgical excision of the tumor. All patients made an immediate recovery with return to full normal function.The presentation of this is unique in that the patient has exquisite pain and tenderness when the area affected is palpated. Occasionally, local infiltration or an ischaemia test can assist with diagnosis. To our knowledge, this is the largest case series in the literature.
