title: Unusual Volar Pulp Location of Glomus Tumor.
abstract: Glomus tumors are benign, painful growths originating from glomus bodies and comprise just 1% of tumors arising in the hand, with fewer than 10% in the volar pulp of digits. Hallmark symptoms of glomus tumors include hypersensitivity to cold, heightened pinprick sensitivity, and paroxysmal pain. We report a 72-year-old, right-hand dominant man who presented with pain in the left middle finger, localized to the tip. The fingertip was incredibly sensitive to touch, and his pain increased at night. He reported no recollection of trauma. Palpation of the finger revealed no mass, although it did indicate a focal point of pain within the distal pulp of the digit. Magnetic resonance imaging of the left hand revealed a round 7.0 × 4.0 × 6.0-mm soft tissue lesion along the volar ulnar aspect of the distal third digit. An incision was made in the mid-axial plane, circumscribing and removing the mass bluntly. It was a tan-yellow, soft tissue nodule of 0.8-cm in diameter without stalk or adherences to joints. Pathology revealed the mass was a glomus tumor. Symptoms improved on removal, and he healed without complication. Glomus tumors in the volar digital pulp can be difficult to diagnose. However, the presence of localized pain in the fingertip was reason to consider glomus tumor and proceed with treatment. Complete surgical removal of a glomus tumor is necessary to resolve symptoms and prevent recurrence.
