Introduction
Glomus tumor is a painful, subcutaneous tumor. The lesion may occur in various locations. In the case of the nail apparatus, it affects both the matrix area and the nail bed.
Case report
We present a 71-year-old patient who presented to our clinic with a painful nodule lasting for about 15 years, located on the fifth finger of his left hand. After surgical removal, a histological examination was performed, which confirmed the clinical suspicion of glomus tumor. Intraoperative contact onychoscopy revealed a gray-blue nodule with linear vessels at the periphery.
Conclusions
In the differential diagnosis of glomeroma, the following should be considered: pyogenic granuloma, subugual viral wart, melanoma, hemangioma, leiomyoma, sweat gland tumor, gout, neuroblastoma and hemangioma. Dermoscopy can be useful in the differential diagnosis, but the final diagnosis is based on a histopathological examination. Surgical removal of the lesion is considered the treatment of choice.
