Juxtacortical Glomus Tumor of the Distal Femur Adjacent to the Popliteal Fossa

Color Doppler Sonography of Extradigital Glomus Tumors

“…All our lesions and all 9 lesions reported by Park et al showed internal flows. A few cases have been reported with no intralesional flow detection at Doppler assessment . However, the EDGT described by Perks et al was small and located deeply in the thigh, and this may have contributed to the lack of vascular signals.…”

“…4 Most of EDGTs arise in the subcutaneous layer of the extremities, although cases located in the head, neck, trunk, or even deeply (bones, larynx, trachea, lung, stomach, colon) have been described. [5][6][7][8][9] Cases of intravenous 7,10 or intraneural 6,11 location have also been reported.…”

Gray‐scale and color Doppler sonographic appearances of nonsubungual soft‐tissue glomus tumors

“…GTs characteristically occur in a subungual location, but nonsubungual locations have been reported. Perks et al6 reported that up to 35% of GTs are extradigital. NSGTs usually occur around the knee joint, such as in the femoral metaphysis, suprapatellar subcutaneous tissue within the joint capsule, the patellar ligament, or Hoffa fat pad.…”

Violaceous painful nodule of the leg in an Indian male patient

“…[1] Glomus bodies lie in the stratum reticularis of the dermis and are particularly numerous in the digits, palms and soles of the feet. [2] Glomus tumors are neoplasms of normal glomus body. They classically present with a triad of symptoms-pain, pin-point tenderness with blunt palpation and hypersensitivity to cold.…”

“…Glomus tumors are most often of solid type, but vascular and myxoid types also occur. [2] Depending on the histology the tumor can be glomus tumor, glomangioma or glomangiomyoma. The stains for reticulin, nerve fibers, factor VIII, keratin, smooth muscle actin and neuroendocrine granules may be needed to clarify the diagnosis.…”
