Benign tumors consisting of glomus cells may be subdivided into two types:
glomus tumors and glomuvenous malformations or glomangiomas.
Long-term survival case of malignant
glomus tumor mimicking "dumbbell-shaped" neurogenic tumor.
Benign tumors were reported as
glomus tumor, epidermal cyst, giant-cell tumors of the tendon sheath, pyogenic granuloma, neurinoma, schwannoma, lipoma, cystic hygroma, hemangioma, arteriovenous malformation, fibroma, fibrolipoma, ganglion cyst, infantile digital myofibroblastoma, dermatofibroma, and verruca vulgaris; whereas the malignant tumors were identified as squamous cell carcinoma (SCC), basal cell carcinoma (BCC), malignant melanoma, fibrohistiocytic malignant tumor, and synovial sarcoma.
Dermoscopic features include whitish, red and purple areas unlike those of hemangiomas with linear and hairpin like vessels at the periphery.6 Differential diagnosis includes hemangioma,
glomus tumor, cutaneous lymphoma, dermatofibrosarcoma protuberans, leiomyoma, follicular cyst, trichilemmoma and metastatic renal cell carcinoma, squamous cell carcinoma or signet-ring adenocarcinoma.1,7 Clinical differentiation is difficult; but characteristic histological features of nodular hidradenoma help in differentiating it from the above conditions.

Glomus tumor is a mesenchymal tumor comprising smooth muscle cells known as glomus cells; it is responsible for thermoregulation (1).
However, other lesions like
glomus tumor, melanoma, mucosal adenoma, fibrous dysplasia, squamous cell carcinoma, adenoma of the endolymphatic sac, encephalocele, and tuberculosis were reported in the remaining patients.
Glomus tumor is a rare benign mesenchymal neoplasm.
Differential diagnoses include papillary renal cell carcinoma,
glomus tumor, hemangiopericytoma, collecting duct carcinoma, urothelial carcinoma, renal epithelioid angiomyolipoma, and Wilms tumor.

Certain tumors more likely to be located in the soft tissue in the hand than in other parts of the body include
glomus tumor, tenosynovial giant cell tumor, and fibroma of the tendon sheath [9].
Glomus tumor is a type of myoepithelial tumor that was first described by Hoyer in 1877.
