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.

An osteoma is a benign, slow-growing, osteogenic neoplasm with a low recurrence rate that is typically characterized by the proliferation of a compact or cancellous bone. It can be peripheral, central, or extraskeletal. Usually asymptomatic, peripheral osteomas in the maxillofacial region commonly arise in the paranasal sinuses and mandible and rarely occur in the zygomatic arch, with only six previously documented cases in the literature. Here, we present the management of a solitary peripheral osteoma of the right zygomatic arch in a 72-year-old woman and a review of the literature.

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.

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.

The third documented case of chondroid syringoma occurring in a toe, involving the largest tumor of the three, along with a review of the literature, has been presented. The possibility of a mixed tumor should be kept in mind when considering the differential diagnosis of a solid nodule in the skin, particularly if it is of long duration. These tumors usually will present as simple, asymptomatic, subcutaneous nodules that are shelled out easily during surgical excision. However, there is a tendency toward local recurrence that usually is attributed to incomplete surgical removal, which easily may occur because of the lobulation of the tumor. Complete excision of the primary tumor always is recommended, as diagnosis can be made only by histopathologic examination. Six reported cases revealed that the recurrence of the lesion following primary excision resulted in malignant degeneration. In nine reported cases where metastasis had occurred, the initial site of metastasis in five patients was the regional lymph nodes, and, in four patients, there was metastasis in the lung. The period of time between the removal of the primary lesion and the malignant local recurrence or metastasis has been reported to be from 1 to 4 years. Recognition of chondroid syringoma is clinically difficult because of its rarity. Its diagnosis requires histologic examination.

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.

Abstract Background First described in 1955 Primary mediastinal seminomas are rare. Only 1–4% of mediastinal tumours are germ cell tumors; majority of which are teratomas. They typically present in men aged between 20 and 40 years. Very few cases are reported in the literature. Florid follicular lymphoid hyperplasia can obscure the malignant cells and is a rarer finding still. We present a rare case of a 48 year old man with a primary mediastinal seminoma with florid follicular lymphoid hyperplasia; found following excision of a clinically presumed thymoma. Case presentation A 48 year old man was referred for excision of a thymic mass. The presumed diagnosis was a thymoma; following preoperative investigations. The mass was incidentally found on a radiological imaging. However, the patient did report mid-sternal discomfort on lying flat and breathlessness. The patient underwent a thymectomy via a partial median sternotomy with good recovery. Histological assessment was that the mass was in fact a primary mediastinal seminoma with florid follicular lymphoid hyperplasia. A primary testicular malignancy was excluded and the patient required no further oncological treatment. Conclusions Only 11 cases have previously been reported of primary mediastinal seminoma with florid follicular lymphoid hyperplasia. Although rare, a primary mediastinal seminoma should be considered as a differential diagnosis for presentations with a thymic mass. Tumour markers can be helpful, however are only positive in third of cases. Ultrasound imaging of the gonads is essential to exclude a primary gonadal lesion. Pure seminomas are radiotherapy and chemotherapy sensitive however the mainstay treatment of primary mediastinal seminomas remains surgical excision. Radiotherapy is reserved postoperatively for incomplete surgical margins.

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.

Epidermoid cysts are one of the uncommon slow growing lesions. There is some amount of controversy prevailing in the uniform understanding of these among the researchers regarding the nomenclature of these lesions. With a critical review of reported cases, author demarcated four different anatomical types of brain stem epidermoids and proposed a new classification system for a better understanding of the natural history.Four years female child presented with insidious onset left sixth and seventh cranial nerve palsy with right hemiparesis. Radiological evaluation revealed a pure intrinsic brain stem cystic lesion. Surgical decompression of the cyst was done, and the child recovered well. Histopathological examination was an epidermoid cyst.Brain stem epidermoids are uncommon, and there is no age or sex predilection. Based on the epicenter these tumors could be classified into four different types. Adequate surgical excision is the hallmark in the treatment. Nepal Journal of Neuroscience, Volume 14, Number 3, 2017, page: 33-41

Schwannomas are rare slow-growing benign tumors arising from Schwann cells lining the nerve sheaths. Head and neck schwannomas account for about one-third of all cases, and only 4% of them arise from the sinonasal tract. Its diagnosis is based on histology and immunohistochemistry. Complete surgical excision is the most recommended treatment option, and endoscopic surgery has been widely performed in recent years. In this study, we presented a case of a 55-year-old female with schwannoma arising from the lateral wall of the nasal cavity, causing epistaxis and rhinorrhea. The patient underwent endoscopic excision with prompt resolution of symptoms. The reported cases of nasal cavity schwannoma were reviewed and summarized for educational purposes.

Osteomas are benign, slow-growing osteogenic tumors commonly occurring in the craniofacial bones. Osteomas are characterized by the proliferation of compact and/or cancellous bone. It can be of a central, peripheral, or extraskeletal type. The peripheral type arises from the periosteum and is rarely seen in the mandible, if involved, the lingual surface and lower border of the body are the most common locations of these lesions. They are usually asymptomatic and can be discovered in routine clinical and radiographic examination. This paper presents a large solitary peripheral osteoma located in the lingual surface of the right posterior mandible. The osteoma was removed surgically, and no recurrence has been observed.Journal of Kathmandu Medical College, Vol. 5, No. 4, Issue 18, Oct.-Dec., 2016, page: 128-130
