Osteoblastoma esclerosante multifocal yuxtacortical (Osteoma osteoide multicéntrico): a propósito de un caso localizado en acetábulo

Abstract

A case of a multifocal sc/erosing osteob/astoma is described, localized in the base of the right hip's acetabulum. The tumor affected a 18 year o/d girl and was rather large (6 cm.). According to a previous x-ray of the patient it developed during tw_o years. The c/inica/, radiological and histological features of this case coincide with criteria for both Osteoid osteoma and osteoblastoma, so that a common denomination for this group of lesions would be desirable.
