Abstract

Subungual glomus tumors are benign neoplasms that arise from the neuromyoarterial apparatus. They present with various clinical symptoms such as localized pain, tenderness, and sensitivity to temperature change and can be palpated as a nodule or mass on physical examination. Pressure erosion can be seen at adjacent bones on radiography. However, in most cases, the tumors are too small to be inspected and located under the nail plate, which makes correct diagnosis and complete excision very difficult. Incomplete removal can cause recurrence or deformity to the residual nail, whereas extensive removal can cause trauma or deformity to the nail plate. Thus, correct differential diagnosis and preoperative evaluation of the location and extent of the tumor are very important. Here, we report 2 cases that were diagnosed and preoperatively evaluated using ultrasound.
