Case for diagnosis. Glomus tumor.

Glomus tumor is a painful tumor derived from the glomus terminal which regulates blood circulation and body temperature Despite its rarity, particular attention needs to be paid to symptoms associated with this tumor: paroxysmal pain, sensitivity to local pressure and cold, and its location - typically in the distal phalanx. Manifestation of extradigital occurrence is possible. Single lesions are most common in adult females, while multiple lesions are prevalent in children and adolescents, generally those with a positive family history. The diagnosis is clinical with the aid of ultrasonography and magnetic resonance imaging, confirmed by histopathological examination.
