Objectives The aim of the present study was to document the frequency and clinicopathologic features of intra-osseous jaw lesions in an Iranian pediatric population over a 20-year period. Methods Data were obtained from the archives of the Oral Pathology Department, Shahid Beheshti University of Medical Sciences, Tehran, Iran. The lesions were classified into four groups: (A) odontogenic cysts...

Histological evaluation revealed multiple fragments of richly cellular mesenchymal tissue containing round droplike islands and long narrow anastomosing cords of odontogenic epithelium. The epithelial islands and cords were characterized by peripheral columnar or cuboidal hyperchromatic cells and were frequently only two cell layers thick (Fig. 2). The mesenchymal component contained evenly dis...

Juvenile ossifying fibroma (JOF) is an expansile intra-osseous lesion of the jaw that emulate odontogenic lesions frequently seen in patients under 15 years of age. They are histologically characterized by the presence of fibrous stromal cells along with mineralized tissues. Clinically, these are characterized by early age of onset, histological patterns, high rate of recurrence and the aggress...

This paper reports one case, of an ameloblastic fibro-odontosarcoma (AFOS) affecting the mandible, in a 12-year-old girl. This neoplasm is a rare odontogenic neoplasm. To the authors' knowledge this is the fifteenth case of AFOS reported in English. The patient's chief complaint was a swelling in the face for 6 months. An incisional biopsy was performed diagnosing the case as an ameloblastic fi...

BACKGROUND: Odontogenic myxoma (OM) is a locally aggressive neoplasm whose clinicopathological characteristics have not been extensively reported in Nigerians. OBJECTIVE: To describe the clinicopathological characteristics of cases of OM seen at the Lagos University Teaching Hospital in Nigeria. METHODS: A review of both clinical and histopathological records of sixty-three cases of OM diagnose...

INTRODUCTION The mandible and maxilla can be the site of myriads of lesions that may be categorized as neoplastic, cystic, reactive and infective or inflammatory. Literature reviewing jaw swellings in an amalgamated fashion are uncommon, probably because aetiologies for these swellings are varied. However, to appreciate their relative relationship, it is essential to evaluate the clinico-pathol...

Ameloblastic fibroma (AF) is an uncommon mixed neoplasm of odontogenic origin frequently seen in the second decade of life. It mainly presents as an intrabony lesion but can even occur peripherally. Histologically, our case showed hypercellular areas, an uncommon feature seen in typical AF. Whether this benign lesion is treated by mode of enucleation and curettage or by extensive surgery is sti...

Peripheral odontogenic lesions are considered to be rare within the classification of odontogenic tumors. They share the same microscopic characteristics of their central counterparts. Here, we report an ulcerated mass of the maxillary gingiva that on histopathological examination was diagnosed as peripheral developing odontoma or peripheral ameloblastic fibroodontoma. The diagnosis of this tum...

INTRODUCTION Ameloblastic fibro-odontoma (AFO) is defined as a benign odontogenic tumor with slow growing behavior. Its prevalence is rare. AFO is characterized by histologic features of ameloblastic fibroma (AF) with the formation of enamel and dentine. CASE PRESENTATION This is a case report of AFO accompanied with a number of impacted deciduous teeth and its management in a 4-year old boy....
