Multiple Osteoid Osteomas on External Table Skull: Leave It or Treat It?

Abstract

Osteoma is a benign, slow growing bone forming tumor that consists primarily of well-differentiated mature, compact or cancellous bone.[1] They usually arise on the surfaces of the cranial vault and are approximately 1-2 cm in size.[1] They are most commonly diagnosed in the fourth or fifth decades of life.[2] Only patients with symptomatic osteomas should be treated, generally by simple excision.[1] The differential diagnosis of bumps on forehead include osteoma, lipoma, sebaceous cyst, osteoblastoma, osteosarcoma and osteomyelitis. Here, we report a case of 45 year old female with bony bumps on forehead diagnosed with multiple osteomas. Keywords: Osteoma, Multiple osteoid osteomas, external table skull
