A glomus tumor is an uncommon, predominantly benign, neoplastic lesion that primarily involves a thermoregulatory microvascular apparatus, the glomus body. Although these lesions can occur anywhere in the body, the subungual tissue of the hand represents the most common presentation site. Glomus tumors are not often encountered in the foot. Symptoms traditionally include the classic triad of pain, pressure, and cold sensitivity. This case report describes a variant location for a glomus tumor in the subcuticular tissue adjacent to the medial middle phalanx of the second toe. The nonsubungual location for this presentation should prompt the inclusion of glomus tumor in a digital soft-tissue lesion differential diagnosis. The lesion was excised surgically and was subsequently diagnosed histopathologically as a glomus tumor.
