3 Cases of Glomus Tumor—An Unusual Cause of Hand Pain

Radiographic pressure erosions are late to appear, and MRI is limited by poor resolution for these small lesions. Point-of-care ultrasound is an ideal modality to confirm the presence of a hypoechoic, discrete, well-defined vascular lesion and limit the duration of preoperative morbidity. Access to high-resolution point-of-care ultrasound is suggested as a method of rapid, sensitive, inexpensive confirmation of diagnosis at peripheral sites common for glomus tumor.

Abraham Chaiton, MD, MSc, FRCPC, RhMSUS, is a graduate of the University of Toronto, where he is an assistant professor in rheumatology. He trained in clinical epidemiology at McMaster University, Hamilton, Ontario, Canada, and as a neuromuscular fellow at Toronto General Hospital. He is a member of the Neurodiagnostic Lab at Humber River Hospital, a founding member and executive staff of the Canadian Rheumatology Ultrasound Society, a past member of the ACR Ultrasound Certification Committee, a member of AANEM Ultrasound Education Committee, active staff at Sunnybrook and Humber River Hospitals, Toronto, and associate staff at Lions Gate Hospital in North Vancouver, B.C. His clinical interests include biologic therapies, myositis, focal nerve entrapments, ultrasound-guided interventions and teaching of POCUS to students and clinicians.

Maggie Larché, MBChB, MRCP, PhD, is an associate professor in the Divisions of Rheumatology and Clinical Immunology and Allergy in the Department of Medicine & Pediatrics at McMaster University and staff Physician at St. Joseph’s Hospital in Hamilton, Ontario, Canada. Following a PhD from Imperial College, London, she trained in rheumatology in London, U.K. She is a founding member and past president of the Canadian Rheumatology Ultrasound Society and chair of the Hamilton Scleroderma Group. Her major clinical interest is in scleroderma and early inflammatory arthritis, with research interests in cellular biomarkers and ultrasonographic and MR imaging in inflam­matory arthritis.
