Juvenile psammomatoid ossifying fibroma: An unusual case report

Abstract

Ossifying fibromas are well-demarcated benign fibro-osseous tumors of craniofacial skeleton most often in the jaws. It has two types, conventional and juvenile ossifying fibroma (JOF). JOF is considered a separate entity from ossifying fibroma due to its locally aggressive behavior and tendency to occur at a young age. Two subtypes of JOF, i.e., juvenile psammomatoid ossifying fibroma (JPOF) and juvenile trabecular ossifying fibroma have been identified on the basis of histology 70% of the JPOF occur in the paranasal sinuses, 20% in the maxilla and only 10% in the mandible. Here, we report a case of JPOF in a 14-year-old girl causing an asymptomatic expansile swelling in the right mandibular posterior region, which is a rare site for this tumor.

A rare cause of maxillary mass: juvenile ossifying fibroma

“…9,10 The psammomatoid variant has a basophilic center, while the peripheral portion sometimes produces optical emissions, giving it a fringed appearance. The trabecular variant reflects the trabecular structure of immature bone, and may or may not be surrounded by osteoblastic activity, unlike spheric or ovoid bone.…”

“…5,9,11 Active, aggressive cellular production of cement tissue rather than osteoid material results in clinical changes and affects the surgical outcome, often necessitating radical procedures. 6,9,10 We performed a left partial maxillectomy, and we have just reached the 1 year follow-up.…”

Fibroma osificante en el maxilar: reporte de un caso y revisión de la literatura

“…Se han identificado dos subtipos de JOF, es decir, el fibroma osificante psamomatoide juvenil (JPOF) y el fibroma osificante trabecular juvenil, sobre la base de la histología, el 70% del JPOF ocurre en los senos paranasales, el 20% en el maxilar y sólo el 10% en mandíbula. 13 El objetivo de este trabajo de investigación es presentar un caso, revelando los aspectos clínicos y tratamiento quirúrgico de manera práctica y sencilla que sirva de orientación y permita un exitoso desenlace en la terapéutica planteada para la resolución de esta patología.…”

Psammomatoid variant of juvenile ossifying fibroma involving mandible: A rare case report

“…It is considered a separate entity from ossifying fibroma due to its locally aggressive behavior and propensity to occur at an adolescent age. [ 1 2 ] The most distinguishing feature of ossifying fibroma is the well-circumscribed appearance of the lesion radiographically, clinically, and the ease with which it is separated from the normal bone surgically. [ 3 ] The juvenile variety is usually present in children and adolescent.…”
