Glomus tumor is a rare benign tumor of the glomus body that was first described surgically by Wood in 1812. In pathologic terms, this tumor is a hamartoma that develops from the neuromyoarterial glomus body, which was originally described by Masson and Popoff. The glomus body is a highly specialized arteriovenous anastomosis that is responsible for thermoregulation. Glomus bodies consist of an afferent arteriole, a tortuous arteriovenous anastomosis,a system of collecting veins, and a neurovascular reticulum that regulates the flow of blood through the anastomosis....

Subungual tumors: benign solid tumors (glomus tumor, subungual exostosis, soft-tissue chondroma,keratoacanthoma, heman-gioma, lobular capillary hemangioma), benign cystic lesions (epidermal and mucoid cysts). malignant tumors (squamous cell carcinoma, malignant melanoma). The normalsubungual space is very small, with a thickness of only 1-2 mm As a result, any tumorsof the subungual space, irrespective of their histologic nature, can erode into the distalphalanx of the digits. Clinical Features in subungual glomus tumor: nail deformity and change of color beneath the nail and a scalloped defect of the distal...

It is important to comprehensively understand the typical and atypical sites and imaging patterns of Glomangiomas and Glomangiosarcomas. Glomus tumors are generally indolent and are cured by surgical resection, so distinguishing atypical glomus tumors from other entities is valuable
