Osteoma is a benign osteogenic neoplasm originating from the continuous proliferation of compact and/or cancellous mature bone. The tumor can be classified as peripheral, central or extra-skeletal regarding location and it commonly seen in the cranio-facial region especially at the skull and paranasal sinuses. The exact etiology of the tumor is still controversial; however, it is considered that infection, trauma, muscle activity contributes the occurrence of the tumor. Due to the slow growing nature of osteoma, it is coincidentally detected on radiographs or when the tumor reaches a large size enough to trigger symptoms and cause facial disfigurement. Although mainly detected in the craniofacial bones, osteomas are rarely located in the jaw bones.  The purpose of this review, is to present the diagnosis and treatment plan of a peripheral osteoma in the mandibular angulus region of an 8-year-old boy together with a review of published cases of peripheral osteomas of mandibular angulus.

Introduction: Osteoma is a benign slow-growing osteogenic neoplasm characterized by the proliferation of cancellous and/or cortical bone. Jaw bones are seldom affected. Observation: We observed a rare case of a patient with a peripheral mandibular osteoma, which was surgically removed. Comments: Frequently asymptomatic, a peripheral osteoma looks like a bony swelling that may be sessile or pedunculated. Imaging examinations show a well-circumscribed radio-opaque mass. Symptomatic osteomas must be surgically excised and submitted for histological evaluation. Conclusion: Excessive osseous healing following a tooth extraction may explain this rare form of osteoma.

Solitary peripheral osteoma is a benign, slow-growing osteogenic tumor arising from craniofacial bones such as the sinus, temporal, or jaw bones but rarely originating from the mandible. Osteoma consists of compact or cancellous bone that may be of peripheral, central, or extraskeletal type. Peripheral osteoma arises from the periosteum and is commonly a unilateral, pedunculated mushroom-like mass. Solitary peripheral osteomas are characterized by well-defined, rounded, or oval radiopaque mass in the computed tomography. Although multiple osteomas of the jaws are a hallmark of Gardner’s syndrome (familial adenomatous polyposis), nonsyndromic cases are typically solitary. Herein, we report a rare case of solitary peripheral osteoma of the angle of the mandible in a 27-year-old female with clinical, radiologic, and histopathologic findings.

Osteoma is a benign slow-growing osteogenic neoplasm commonly occurring in the craniofacial skeleton, characterized by the proliferation of compact and/or cancellous bone. Osteomas may be peripheral, central, or extraskeletal. Peripheral osteomas arise from the periosteum and are quite uncommon in the jaw bones. The exact aetiology and pathogenesis of peripheral osteoma are unknown. Clinically, peripheral osteomas are usually asymptomatic, but depending on the location and size of the lesion, it may cause swelling, pain, esthetic disfigurement and functional impairment. On radiological imaging, a peripheral osteoma appears often as well-circumscribed, round to oval, pedunculated radiopaque mass attached to the cortex by a broad base or a pedicle. Asymptomatic osteomas are treated conservatively, while surgical excision is indicated when the lesion is symptomatic, actively growing, or for cosmetic reasons. Histologically, osteomas are composed of a normal-appearing, dense mass of lamellar bone. Recurrence of peripheral osteoma after surgical removal is extremely rare and there are no reports of malignant transformation. A review of the literature disclosed only 7 well-documented cases of peripheral osteoma located at the zygomatic bone. The purpose of this article is to present the clinical, radiographic, surgical and histological features of a solitary peripheral osteoma of the left zygomatic arch in a 55-year-old woman and to review the literature about this uncommon pathologic entity.

Lipomas are benign soft tissue neoplasm which rarely occur in the oral cavity. Of the total reported cases of lipoma, only about 15% to 20% of cases have occurred in the head and neck region and the tongue is an even rarer site with only about 4% of the reported cases occurring in that region. They are slow growing and usually asymptomatic in nature. When it grows to a large size, it can hinder the physiological processes that are associated with the area. This case report describes the diagnostic features of tongue lipoma with a brief review of literature.

Muscle Invasive Tumor

Dermatofibromas are common benign fibrohistiocytic lesions, usually appearing as slow growing firm dermal nodules with a predilection for the extremities (mostly the lower legs). They are found mostly in middle-aged women and are usually smaller than 2 cm in diameter. Giant dermatofibromas exceeding 5 cm in diameter are rare. In recent years, reports have suggested a relationship between the primary size of dermatofibromas and rates of local recurrence and metastases after surgery. This relationship is however debated. The present report describes the case of a giant muscle invasive tumor in a 51-year-old female patient who presented with a large ulcerated mass in the right upper arm. The tumor appeared clinically malignant, measuring approximately 12 cm × 6 cm in size, with ulceration and invasion of surrounding muscle. Wide resection of the tumor was performed with myocutaneous flap-plasty. Histopathological examination showed evidence of a dermatofibroma. No recurrence, metastases, or other complications were noted at 5 years after surgery. The present case demonstrates that although dermatofibromas are essentially benign, they may present with atypical features including large size, ulceration, and muscle invasion, clinically mimicking malignant tumors.

Osteomas are bone tumours arising from the cortical or medullary bones of craniofacial skeleton. Involvement of frontal bone and paranasal sinuses is more frequent than jaw bones. Jaw osteomas are slow growing benign lesions, which are usually asymptomatic or present as painless swelling. Those involving mandibular condyle are relatively rare and result in significant functional and aesthetic disturbances. This paper reports a case of solitary central compact osteoma of mandibular condyle in an adult Indian female patient. A comprehensive review of previously published reports is also presented.

AbstractCysts of the Oro-Maxillofacial region have common occurrence in comparison to any other parts of the body. These can be true cysts or pseudocysts and can be found in the jaw bones or in the soft tissues. Cysts are of various types, and over the years, various classifications are put forward, which are helpful to identify each cyst, based on its origin and its clinical and histopathological presentation. Based on the classification, one can also decide the treatment plan accordingly. The classifications are given by various researchers and also by WHO. In this chapter, various odontogenic and nonodontogenic cysts and their treatment aspect are discussed in detail.

The ameloblastoma is a rare odontogenic tumor of the oral cavity. It is slow growing, locally invasive benign tumor affecting mandible more than maxilla mostly in age group 30-60 years. It grows in bone and soft tissue causing facial disfigurement. Treatment is surgical taking wide margins. This case report describes the treatment of a 30-year-old female having right side jaw swelling since two years, fine needle aspiration cytology was suggestive of ameloblastoma. Right hemi mandibulectomy was done by head and neck surgery team and reconstruction was done by plastic surgery team using free fibula flap. The free fibula osteocutaneous flap is the most versatile and reliable option for microsurgical reconstruction of large mandibular defects.

A study of 6 selected arteriovenous malformation (AVM) patients was performed to investigate the feasibility of delineating an AVM on MR images and to compare the AVM volume outlined on different images. Conventional stereotaxic angiograms, stereotaxic MR images and MR angiograms using several different pulse sequences were obtained prior to radiosurgery. Treatment plans were made from the conventional stereotaxic angiograms. These plans were then transferred to a separate dose planning computer which displayed the MR images with the superimposed isodose lines. The radiated volumes of AVM and brain tissue were measured from these MR images. Last, an assessment was made of the radiation volume needed for an appropriate treatment of the AVM if the treatment plan was made from the MR images rather than from the conventional stereotaxic angiogram. It was possible to delineate medium and large size AVM nidi on stereotaxic MR images based on an integration of information obtained from various pulse sequences. The estimated volumes of the AVM nidi were found to be larger on the conventional stereotaxic angiograms than on the stereotaxic MR images. Consequently, a dose plan based on a conventional stereotaxic angiogram would result in a higher integral dose to the brain with the same target dose. By using reliable MR information it is expected that the volume of brain exposed to radiation could be decreased and the adverse effects of stereotactic radiosurgery for AVM thereby minimized.

<p class="abstract">Chondroid syringoma (CS) is a rare benign appendageal tumour of the skin, with histological similarities to pleomorphic adenoma of salivary glands. It typically presents as a slow growing nodular mass generally less than 3 cm, arising from the skin, predominantly in the head and neck region. We report a case of a 61-year-old male with a massive nasal mass attained over a period of 2 years. A fine needle aspiration of the lesion was suggestive of CS. It was excised completely under general anaesthesia. The postoperative histopathology was also consistent with CS. The patient was followed up on a regular basis and was rendered disease free till his last follow up at 4 months. Our purpose of reporting this case is to highlight the rarity of the disease entity, as well as the occasion of it acquiring a large size yet, maintaining its benign nature.</p>
