Osteosarcomas of the jaw are comparatively rare and represent only 2-10% of all osteosarcomas. We herein present a rare case of an osteosarcoma exhibiting the radiographic and histological characteristics of cemento-osseous lesions in the alveolar ridge of the maxilla. A 53-year-old male patient presented with the complaint of gradual swelling of the left maxilla over 4 years. Radiography revealed an ill-defined radioopaque mass, intimately associated with the apices of the involved teeth, without a periosteal reaction...

Osteoid osteoma is a benign bone tumour with self-limiting growth potential occurring in any part of the body. Two rare cases of a pathologically proven osteoid osteoma invading the temporomandibular joint (TMJ) are reported herein. This article also reviews the cases of osteoid osteoma of the craniofacial complex reported in the English-language literature to date. Although the clinical presentation of osteoid osteoma in the jaw differs from that of osteoid osteoma in the more common locations, the radiographic features are similar...

Cherubism is a rare hereditary developmental condition of the jaws and generally inherited as an autosomal dominant trait. It is also known as familial fibrous dysplasia of the jaws, familial multilocular cystic disease and hereditary fibrous dysplasia of the jaws. The gene for cherubism is mapped to chromosome 4p16.3 may lead to pathologic activation of osteoclasts and disruption of jaw morphogenesis. The lesion usually appears between 2 and 5 years shows a predilection for the mandible and causes a bilateral swelling giving rise to a cherubic chubby appearance...

Mucoepidermoid carcinoma (MEC) is the malignant salivary gland neoplasm chiefly occurred in minor salivary gland. One of the rare variant of MEC is intra-osseous variant found in the jaws known as central mucoepidermoid carcinoma. Presently in this case report, we described a 28-year-old male diagnosed with central low grade mucoepidermoid carcinoma subsequently with the presence of asymptomatic swelling with a history of trauma. Clinically mimicking a cystic lesion and radiographically gives an idea of mixed radio-opaque radiolucent lesion which creates a confusion to render a final diagnosis...

This project was started after an incident of bisphosphonate-induced hypocalcaemia in September 2015. As part of management of lytic bone lesions in patients with multiple myeloma were given either Zoledronic Acid or Pamidronate Disodium at our Haematology Day Unit. According to the British National Formulary (BNF), it is necessary to correct disturbances of calcium metabolism (e.g. vitamin D deficiency, hypocalcaemia) and consider dental check-ups before starting bisphosphonate infusion due to the risk of osteonecrosis of the jaw...

Osteoid osteomas are benign skeletal neoplasms that are commonly encountered in the bones of the lower extremities, but are exceedingly rare in jaw bones with a prevalence of less than 1%. This unique clinical entity is usually seen in younger individuals, with nocturnal pain and swelling as its characteristic clinical manifestations. The size of the lesion is rarely found to be more than 2 cm. We hereby report a rare case of osteoid osteoma originating from the neck of the mandibular condyle that grew to large enough proportions to result in conductive hearing loss in addition to pain, swelling and restricted mouth opening...

Orocutaneous fistula (OCF) of dental origin is a relatively rare condition and continues to be a challenging diagnosis. Misdiagnosis of OCF usually leads to unnecessary and noneffective treatment. A 21-year-old male referred with a complaint of a lesion on the chin which was misdiagnosed as a carbuncle (lesion of nonodontogenic origin) by a physician. After radiological examination, there was a lesion around the apical region of right central incisor. These findings indicated a sinus tract associated with dental origin...

SUMMARY: Parathyroid carcinoma is an extremely rare disorder with little treatment options. It could be misdiagnosed in medical centers with little experience in management of such cases. Our clinical case shows that the initial misdiagnosis of a parathyroid carcinoma in a young woman has led to the development of multiple lung metastases, thus making its treatment hardly possible. Initiation of treatment with sorafenib - a multi-kinase inhibitor approved for treatment of different types of cancer but not parathyroid carcinoma - has led to a significant decrease in the size of lung metastases and has prevented the progression of hyperparathyroidism, which is usually severe in cases of parathyroid carcinoma...

Ectopic meningiomas are a very rare tumor entity. We present a case of a meningioma arising in the mandible of a young woman and initially supposed to be a radicular cyst. Histopathological and immunhistochemical evaluation showed typical cell characteristics of a meningioma. Only six cases of ectopic meningiomas in the mandible have been described in the literature until now, mainly in women at an advanced age and with surgical removal of all tumors. For the first time, no surgical excision has been performed in this case and follow-up control after 12 months showed no significant progression or increasing clinical complaints...

OBJECTIVES: Keratocystic odontogenic tumor (KCOT) demonstrates variable growth mechanisms and biologic behavior, partly due to origin and histology. We looked for the most contributing factors in predicting outcome of treatment. SUBJECTS AND METHODS: We retrospectively reviewed 118 medical files of patients diagnosed with KCOT (by tissue biopsy before surgical treatment) with/without nevoid basal cell carcinoma syndrome (NBCCS) from 1995 to 2015. Data were recorded and analyzed statistically to determine the treatment-outcome correlation...

Cemento-ossifying fibromas are rare fibro-osseous benign neoplasms that affect the jaws. They are included in the group of mesodermal odontogenic tumors and commonly present as a progressively growing lesion that might attain enormous size with resultant deformity, if left untreated. A confusion prevails on the terminology, which can only be confirmed by histopathologic evaluation. A case of cemento-ossifying fibroma involving the right mandible is described in a 30 year-old female patient. The clinical, radiographic, histologic features are presented and the various differential diagnosis are discussed...

Odontogenic myxoma (OM) is a non-metastasizing neoplasm of mesenchymal origin, arising in the tooth-bearing areas of the jaws. When regarding the whole spectrum of differential diagnoses for osteolytic jaw lesions, OM constitutes a benign tumor rarely located in the maxilla. Radiographically, displacement of teeth and frequent involvement of the sinus will be found with advanced maxillary OM. The tumor can be removed by means of several techniques, ranging from conservative measures to extended surgical procedures that differ according to type of bone resection and reconstruction of the defect...
