Background: Maxillofacial tumours in children and adolescents have been documented worldwide; however, few studies were reported from Africa, especially sub-Saharan Africa. In Nigeria, most of the studies emanated from the Southwest region. Aim: To present an audit of clinicopathologic features and treatment of orofacial tumours in children and adolescents in Sokoto, Northwest Nigeria. Patients and Methods: Clinicopathologic records of the Departments of Dental and Maxillofacial Surgery, Paediatrics and Histopathology, Usmanu Danfodiyo University Teaching Hospital, Sokoto, Nigeria, were reviewed for all the oral and maxillofacial tumours managed in children <19 years from January 2011 to December 2015...

Large, benign intramandibular lesions are frequently removed by resection followed by extensive free tissue transfer or delayed bone grafting. We outline a protocol to remove benign mandibular lesions using sagittal split osteotomy (SSO) with virtual surgical planning (VSP) to mitigate risks involved with this effective, tissue-saving approach. Patients with benign mandibular lesions accessed by SSO with VSP during 2014 were included in this study. Computed tomographic data were imported into VSP software. Using VSP, the exact locations of mandibular lesions and the inferior alveolar nerve canal were delineated...

Cherubism is a congenital childhood disease of autosomal dominant inheritance. It is a benign, familial giant cell lesion characterized by gradually progressive painless swelling of the jaws. Idiopathic gingival enlargement is a rare condition and may be associated with some uncommon syndromes. This case report describes an 11-year-old patient with unusual clinical form of gingival enlargement, cherubic facial appearance. Clinical examination revealed the presence of the hyperplastic gingiva, which completely covered all teeth...

Bisphosphonates are formidable inhibitors of osteoclast-mediated bone resorption employed for therapy of multiple myeloma (MM) subjects with osteolytic lesions. Osteonecrosis of the jaw (ONJ) is an uncommon drug-induced adverse event of these agents. MicroRNAs (miRNAs) are a group of small, noncoding RNAs nucleotides, which are essential post-transcriptional controllers of gene expression. They have a central role in the normal bone development. The goal of our study was to investigate 18 miRNAs, whose targets were previously validated and described in MM subjects without ONJ, in peripheral lymphocytes of MM subjects with bisphosphonate-induced ONJ...

BACKGROUND: The hyperparathyroidism (HPT) is a condition in which the parathyroid hormone (PTH) levels in the blood are increased. HPT is categorised into primary, secondary and tertiary. A rare entity that occurs in the lower jaw in association with HPT is the so-called brown tumour, which an osteolytic lesion is predominantly occurring in the lower jaw. It is usually a manifestation of the late stage of the disease. Osteosclerotic changes in other bones are almost always associated with renal osteodystrophy in secondary HPT and are extremely rare in primary HPT...

Gorlin-Goltz syndrome (GGS), also known as nevoid basal cell carcinoma syndrome, is an autosomal dominant inherited disorder with high penetrance and variable expressivity. The classic triad originally described by Gorlin and Goltz in 1960 is composed of multiple nevoid basal cell carcinomas (NBCCs), odontogenic keratocysts (OKCs) in the jaws and bifid ribs. in 1977, this triad was modified by Rayner et al, and to GGS diagnosis, the OKCs had to appear in combination with calcification of the cerebellar falx or palmar and plantar pits...

Localized juvenile spongiotic gingival hyperplasia (LJSGH) is a gingival lesion with unique clinicopathologic features that may involve synchronously multiple sites. We present a case with lesions clinically consistent with LJSGH in four jaw quadrants, confirmed by biopsy and review the English literature on multifocal LJSGH cases. A 19 year-old woman presented with circumscribed, erythematous overgrowths on the right and left maxillary and mandibular gingiva. With the provisional diagnosis of multifocal LJSGH, total excision of four maxillary lesions was performed...

Tumor metastasis to the oral cavity is rare and is usually an indication of late-stage disease and poor prognosis. While, there are reports of renal cell carcinoma (RCC) metastatic to oral cavity, vast majority of them are to the jaw. Herein, we present a case of a 78-year-old woman with RCC metastasis limited to the oral soft tissue without any bone involvement. As the lesion solely involved maxillary gingiva, it clinically mimicked that of a pyogenic granuloma, which is a reactive, nonneoplastic condition...

Oral cavity is not a usual site for metastasis, accounting about 1% of all oral tumors. The majority site for metastasis is the mandible and less common the maxilla followed by intraoral soft tissue. These tumors may be the first clinical manifestation of the primary lesion. One of the most important sites of the primary neoplasm that metastasizes to the jaws is kidney. Therefore, considering to this fact that the metastatic tumors always are not seen in a typical site, it is necessary to rule out the metastatic carcinomas to jaws...

Odontogenic myxoma is a benign locally aggressive neoplasm with a sparse prevalence and incertitude histogenesis. They constitute 3%-6% of odontogenic tumors in gnathic bones. It is ubiquitously seen between vicenarian to early quadragenarian group with female proclivity and fondness to the mandibular jaws. They are silent lesions clinically and show myxoid stroma amidst fibrous background. This report highlights central odontogenic myxoma in a 43-year-old male patient and focuses on concepts, differential diagnosis, molecular concepts and treatment aspect...

Medication-related osteonecrosis of the jaw (MRONJ) is a severe side effect of antiresorptive (bisphosphonates and denosumab) and anti-angiogenic therapy used in the management of oncologic and, less frequently, osteoporotic patients. While there is good international agreement on the diagnostic and staging criteria of MRONJ and the cessation of antiresorptive/anti-angiogenic treatments, the gold standard of treatment is still controversial, in particular between non-surgical and surgical approaches. The former usually includes antiseptic mouth rinse, cyclic antibiotic therapy, low-level laser therapy and periodic dental checks; the latter consists of surgical necrotic bone removal...

INTRODUCTION: Osteonecrosis of the jaw associated with bisphosphonates is currently called medication-related osteonecrosis of the jaw (MRONJ), given that in addition to bisphosphonates, jaw osteonecrosis has been related to the administration of other antiresorptive and antiangiogenic drugs, such as denosumab, sunitinib, bevacizumab and ipilimumab. CASE PRESENTATION: A 77-year-old patient with osteoporosis treated with subcutaneous injections of denosumab at an interval of 6 months is presented...

BACKGROUND: Chronic recurrent multifocal osteomyelitis (CRMO), also known as chronic nonbacterial osteomyelitis, is a rare, noninfectious inflammatory disorder that causes multifocal bone lesions with swelling and pain. Lytic and sclerotic bone lesions could be found on X-ray. Short tau inversion recovery magnetic resonance imaging (STIR MRI) shows bone marrow oedema, bone expansion, lytic areas and periosteal reaction. CRMO is characterized by periodic exacerbations and remissions of unclear/unknown pathogenesis...
