Intracephalic glomus tumor presenting as peripheral neuropathic pain and literature review

“…Interestingly, all these characters are genuine features of neuropathic pain. As previously mentioned, the forearm is the most common extra digital location, and the lesions most commonly occur in the subcutaneous layer, with very infrequent occurrence in extra cutaneous locations such as muscle, bone, and blood vessels [10,15] . Superficially located glomus tumors often produce typical symptoms such as paroxysmal pain, exacerbated by changes in temperature [9] .…”

“…The forearm is the most common extra digital site, however, the intravascular origin of a forearm glomus tumor is an exceedingly rare occurrence. To the best of our knowledge, only 3 cases of intravascular forearm glomus tumors have been reported [10,11] . We will present an interesting rare case of a patient with chronic peripheral neuropathic pain and cold intolerance caused by an intravascular glomus tumor in the forearm.…”

“…The forearm is the most common extra digital location, and the lesions most commonly occur in the subcutaneous layer. Extra cutaneous glomus tumors occur very infrequently in locations such as muscle, bone, periosteal, intravascular and intraneural layers [10,11] . They are usually solitary but a multiple glomus tumor syndrome has been described and is transmitted in an autosomal dominant pattern [9] .…”

“…The glomus body is a normal specialized arteriovenous malformation that plays a role in thermoregulation [10] . Glomus tumor is a benign highly vascular neoplasm composed of modified smooth muscle cells and is believed to originate from the glomus body within the reticular dermis.…”
