Glomus tumor of the thumb: case report

Abstract

We report on a case of glomus tumor in the right thumb. The tumor had a 2-year clinical history. The patient reported the development of a 3-5mm tumor in the distal phalangeunder the nail of the right thumb. The patient also complained of severe and progressive pain. Tests using bidirectional Doppler and echo-color-Doppler revealed a presumptive diagnosis of arteriovenous malformation based on the turbulence of the flow and absence of stenosis. The tumor was removed by open surgery and sent for histopathological examination, which showed a diagnosis of glomangioma. The present report describes a rare disease causing extreme discomfort to the patient, which may be treated with surgical resection without sequelae.
