Background:
Glomangioma is a benign tumor of mesenchymal origin, derived from the glomus body. It is responsible for the thermal regulation of the dermis. The occurrence of oncogenic osteomalacia related to glomangioma is rare. Only two cases have been reported thus far.
Case Presentation:
A 32-year-old female, Brazilian, presented diffuse pain, during pregnancy, that developed progressively, limiting her mobility. Imaging showed a femoral neck fracture, and rheumatological laboratory examination showed hypophosphatemia. Also, the patient reported episodes of epistaxis during childhood and recurrence along with progressively right nasal obstruction. Endoscopic resection of the tumor was performed, and immunohistochemistry was conclusive for glomangioma. This case report describes the third case in which endonasal endoscopic surgery resulted in a favorable outcome.
Conclusion:
This case of glomangioma-induced oncogenic osteomalacia suggests that surgeons and clinicians should consider sinonasal tumors as a differential diagnosis of osteomalacia, and endonasal endoscopic surgery should be a possible curative resection.
