Glomus tumor-induced lower extremity pain: A case report

Abstract

Highlights Glomus tumor is a rare small benign perivascular tumor, which develops from the glomus body located in the reticular dermis. The pain caused by glomus tumor could be easily mistaken to lower extremity pain whether it is radiating, sciatic, or just a localized one. A localized thermoregulator subcutaneous tumor could generate paroxysmal pain and sensitivity to pressure which is feigned as chronic radiating pain. A thorough examination is the key to a proper diagnosis of uncommon locations of the tumor.

Giant thigh glomus tumor of uncertain malignant potential: Case report with pathologic–radiologic correlation

“…The location in the thigh is unfrequent 5 . Thirty‐three cases of thigh GT have been reported in English literature 5,6,8–21 . In a series of 138 GT reported by Mravic et al, 22 11.6% cases were located in legs, but there is not specified thigh location.…”

“…5 Thirty-three cases of thigh GT have been reported in English literature. 5,6,[8][9][10][11][12][13][14][15][16][17][18][19][20][21] In a series of 138 GT reported by Mravic et al, 22 11.6% cases were located in legs, but there is not specified thigh location. GT are usually small lesions (<1 cm) 4 but cases over 10 cm have been reported in ankle and paraspinal area by Folpe et al 8 Other thigh GT reported cases were small size lesions (between 0.5 and 3 cm).…”

“…GT are usually small lesions (<1 cm) 4 but cases over 10 cm have been reported in ankle and paraspinal area by Folpe et al 8 Other thigh GT reported cases were small size lesions (between 0.5 and 3 cm). 5,12,14,15,[17][18][19] In these cases, a wide sample of different tumoral areas must be performed.…”

Extradigital glomus tumour of the thigh causing 8 years of undiagnosed debilitating pain

“…Of the extradigital glomus tumour cases found in the literature, all cases report a similar story—a patient with a long-standing history of undiagnosed focal pain (table 1). 2 3 8–17 Oral and topical analgesics, as well as physical therapy, do not provide patients with adequate symptom relief. While histopathological findings provide the definitive diagnosis, medical imaging can be helpful in suggesting a diagnosis.…”

“…Glomus tumours can be seen on ultrasound imaging as hypoechogenic, fluid-filled or cyst-like structures. If Doppler imaging is performed, it often demonstrates blood flow to the lesion 10 11. On MRI T1-weighted images, glomus tumours appear as low intensity subcutaneous tissue masses that enhance with gadolinium.…”
