The glomus tumor is a benign lesion that was once thought to represent hyperplasia or a hamartomatous development of the glomus body.1 However, it is now considered a true neoplasm. To our knowledge, there are only 8 other cases of an intranasal glomus tumor reported in the English-language literature.1,2 The glomus body is a specialized arteriovenous anastamosis that is thought to play a role in regulating cutaneous blood flow and, therefore, thermoregulation.3 This specialized structure is found on the skin throughout the body, but it is most abundant in areas such as the fingertips, pinnae, and nose. Glomus tumors, which may be preceded by trauma and may display a dominant inheritance pattern, are typically encountered in the extremities, especially in the subungial region. Occasionally, glomus tumors are encountered in other sites, such as the deep soft tissues, bone, vagina, trachea, lung, and gastrointestinal tract; they are only rarely seen in the head and neck.4
