| ==Overview==
| |
| Ultrasound may be helpful in the diagnosis of glomus tumor. Finding on finger ultrasound suggestive of subungual glomus tumor includes subungual hypoechoic lesion at the region of maximum tenderness. Doppler ultrasound may be helpful in the diagnosis of glomus tumor. Findings on doppler ultrasound suggestive of glomangioma include hypervascularity of the tumor.<ref name="pmid24470715">{{cite journal| author=Grover C, Khurana A, Jain R, Rathi V| title=Transungual surgical excision of subungual glomus tumour. | journal=J Cutan Aesthet Surg | year= 2013 | volume= 6 | issue= 4 | pages= 196-203 | pmid=24470715 | doi=10.4103/0974-2077.123401 | pmc=PMC3884883 | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=24470715 }} </ref>
