Glomus tumors are rare benign neoplasms composed of glomus cells, blood vessels, and smooth muscle cells. They are classified according to the dominant cell type into three types: glomangioma (60%), solid glomus tumors (25%), and glomangiomyoma (15%). The tumors exist in two forms, solitary and multiple. The solitary nodules may be very painful upon palpation. Multiple glomangiomas are non-tender. The most common site for these tumors is on the distal extremities but tumors on the glans penis may be seen. Multiple glomus tumors are inherited in an autosomal-dominant pattern with incomplete penetrance.
