Glomus-like bodies within a neurofibroma: a novel neoplasm arising in neurofibromatosis type 1 or a coincidence?

Neurofibromatosis type 1 is a relatively common genetic disorder with variable phenotypes. Tumors with features of both glomus tumors and neurofibromas are exceedingly rare in literature. Herein, we report a not yet described neoplasm with features of both a glomangioma/glomus tumor and a neurofibroma arising in a patient with segmental neurofibromatosis. Our case report supports the theory of a common lineage/ancestor cell between neurofibromas and glomus tumors and adds it to the spectrum of neoplasms that may arise in the setting of Von Recklinghausen's disease.
