The case of an intraosseous leiomyoma in a 22-year-old man is presented. The tumor was incidentally discovered during dental radiographic examination for endodontic treatment of mandibular first molar. Radiographic examination revealed a well-defined unilocular radiolucency between the roots of mandibular left canine-first premolar, measuring approximately 1.9 x 1.8 cm and perforation of the buccal cortical plate. Histological and immunohistochemical examination was diagnostic of intraosseous solid leiomyoma. Here, we report a rare case of leiomyoma of the mandible, together with conventional histopathologic and immunohistochemical findings.

Pseudosarcomatous fibromatosis (PSF), also known as nodular fasciitis and pseudosarcomatous fasciitis, is a rare, benign proliferation of fibroblasts and myofibroblasts. It is often misdiagnosed as sarcoma because of its characteristic rapid progression, leading to unnecessary and aggressive surgery. Here we report a case of PSF found in the masseter muscle in a 26-year-old female. The mass that could be misdiagnosed because of its rapid growth characteristics was surgically excised by an intraoral approach and diagnosed as PSF by histopathologic examinations.

Background: In some clinical guidelines followed in clinical practice, nonsurgical treatments are recommended as the primary intervention for patients with lumbar disc herniation (LDH). However, the effect of a therapeutic exercise program based on stabilization of the lumbar spine for treatment of multilevel LDH has not been evaluated thoroughly. Objective: To investigate the effects of therapeutic exercise on pain, physical function, and magnetic resonance imaging (MRI) findings in a patient with multilevel LDH. Design: Case Report Methods: A 43-year-old female presented with low back pain, radicular pain and multilevel LDH (L3–L4, L4–L5, L5–S1). The therapeutic exercise program was conducted. in 40-min sessions, three times a week, for 12 weeks. Low back and radicular pain, lumbar disability, and physical function were measured before and after 6 and 12 weeks of the exercise program. MRI was performed before and after 12 weeks of the program. Results: After 6 and 12 weeks of the therapeutic exercise, low back and radicular pain and lumbar disability had decreased, and lumbar range of motion (ROM) was improvedbilaterally, compared with the initial values. Also improved at 6 and 12 weeks were isometric lumbar strength and endurance, and the functional movement screen score. The size of disc herniations was decreased on MRI obtained after 12 weeks of therapeutic exercise than on the pre-exercise images. Conclusions: We observed that therapeutic exercise program improved spinal ROM, muscle strength, functional capacity, and size of disc herniation in LDH patient.

Low back pain (LBP) is the most common reason for seeking physical therapy (PT) care. Recent studies suggest that axial loading can have a positive impact on the intervertebral disc by improving its tensile strength. Further, whole body vibration (WBV) appears to improve spinal muscle relaxation. Therefore, this case study describes the use of axial loading using a minitrampoline in a female with chronic LBP. This case report is a single subject design. This patient is a 29-year-old female with a six-month history of low back pain following a motor vehicle accident. MRI found herniated discs at L4 and L5, clinical tests were positive for pain in the L4 and L5 dermatome and myotome the slump test was positive for neural tension, and LBP was constant at 4-6/10 over the past four months. She received axial loading exercises using a mini-trampoline and performed six sessions that were, scheduled twice a week for three weeks. Her Oswestry Disability Index (ODI) score improved from 40% at the time of her first visit to 22% at her final visit. Pain measure on the Numeric Pain Rating Scale (NPRS) after the first treatment was 7/10, and her pain after the final treatment was 0/10. These changes in the pain scores are clinically significant and exceed the minimal clinically important difference (MCID). This patient had a significant improvement in her pain using the NPRS and the ODI. This case study suggests that axial loading may be an effective treatment for some individuals with discogenic chronic low back pain.

Extranodal intraoral Hodgkin lymphoma is not common. We report the case of a 78-year-old male patient with ulcer of the mandibular oral mucosa that was not cured for about 3 weeks. In biopsy and histopathologic examination, it was found to be extranodal intraoral Hodgkin lymphoma. Early diagnosis of oral lesions led to early detection of lesions of the opposite neck lymph node in an additional PET-CT scan. We report this case and review relevant literature.

Undifferentiated pleomorphic sarcoma (UPS) in the mandible region is a rare malignant neoplasm. We encountered the case of a patient who had been diagnosed with deep benign fibrous histiocytoma (DBFH) prior to surgery, but the final biopsy revealed the presence of tumor tissues in the resected margin, which indicated a UPS. Therefore, radiotherapy was conducted post-operatively, but the tumor recurred approximately 3 years later and a second surgery was performed. The difference between the initial and final diagnoses was considered to be due to the characteristics of the tumor, as it involved both benign and malignant components. DBFH and UPS can occur in young women. DBFH can transform to a malignancy and UPS may also appear as a benign tumor during early biopsy. Hence, attention should be paid to diagnosis and treatment methods, and ongoing close observation is required.

Dentigerous cysts, the most commonly occurring developmental cysts of the jaw, develop in association with impacted teeth. Most dentigerous cysts are solitary. Multiple dentigerous cysts are rare and generally occur in association with a developmental syndrome or systemic disease, such as mucopolysaccharidosis and cleidocranial dysplasia. However, in the absence of a syndrome, occurrence of multiple dentigerous cysts is rare. Development of multiple dentigerous cysts on first molars extremely rare. The purpose of this paper was to report on a nonsyndromic, 8-year-old boy who presented multiple dentigerous cysts on first molars.

Lipomas are the most common benign mesenchymal tumors composed of mature adipocytes. They are usually slow-growing, soft and asymptomatic masses. Angiolipomas are rare benign soft tissue tumors that are distinguished from common lipomas by a marked degree of vascularization. The diagnosis and prognosis of angiolipomas are based entirely on the findings of histological evaluations. Angiolipoma, showing characteristics of both lipoma and hemangioma, usually develop in the trunk and extremities, and rarely arise in the head and neck region. Angiolipoma of the cheek is very rare. This report presents the clinical and histopathological features of infiltrating angiolipoma excised from the cheek.

Osteoblastoma(OB) is a rare tumor of bone representing less than 1 % of all tumors of the maxillofacial region. The lesion usually appears in vertebral column, sacrum, long bones but rare in mandible or maxilla. The lesion occurs most commonly at age from 3 to 78 years with the mean age of 22-23 years. In this article, we report one case of OB occurred in mandible. With clinical examination and radiological diagnosis, preliminary diagnosis was made as Fibro-osseous lesion, osteomyelitis or cementoblastoma. Under general anesthesia, associated tooth was extracted and excisional biopsy was done. After microscopic examination, it was diagnosed as OB. The patients which we presented did not complain any specific complications, and showed good prognosis.

Central odontogenic fibroma(COF) is an extremely rare benign tumor that accounts for 0.1% of all odontogenic tumor. COF is regarded by the World Health Organization(WHO) as a benign odontogenic neoplasm derived from mesenchymal odontogenic tissue. The lesion occurs most commonly in the mandible and patients ranging in age from11 to 80years with mean age of 34years. In this article, we report two case of COF. Case I was associated odontoma and impacted tooth. Odontoma and impacted tooth was removal under general anesthesia. After microscopic examination, finally we diagnosis this lesion as COF. Patients of case II showed radiolucent lesion at the mandible. Lesion was enucleated under general anesthesia. After microscopic examination, finally we diagnosis this lesion as COF. The patients which we presented did not complain any specific complications, showed good prognosis.

Ameloblastoma is a benign odontogenic tumour of epithelial origin and comprises 1% of maxillomandibular tumors or cysts. The incidence of pathological changes such as ameloblastoma from the follicle of impacted third molar was reported to have low incidence. However, there are many reports that asymptomatic third molars are related with various pathological conditions. A case of ameloblastoma secondary to third molar extraction and subsequent sagittal split ramus osteotomy (SSRO) had not been reported. At the right ramus area, radiolucent lesion had been noted at 6 years after the surgical extraction of the third molar followed by SSRO for the mandibular prognathism. The lesion was proved to be the basal cell type ameloblastoma. There had been no significant bony lesion before or 1 year after the SSRO. The tumour was successfully removed and there was no evident recurrence at 4 year of the follow up after the removal of the ameloblastoma. There are some reports suggesting the pathologic potential of the pericoronal tissues of impacted third molars to develop odontogenic keratocysts and ameloblastomas. The current case reports a rare possibility of ameloblastic change at the site of uneventful healing after third molar extraction and orthognathic surgery.

Purpose of this study is to describe the treatment, surgery, rehabilitation and return to daily life subject pectoralis major muscle rupture. The in patient with was a 26 years old, injured in training due to hyperextension and external rotation. Physical examination, manual test, and MRI were used to diagnose pectoral muscle rupture and operation took for the pectoralis major muscle rupture with allograft. The subject was referred for rehabilitation from 3 weeks. Range of motion (ROM) exercise was mainly performed until 3 months, strength was performed with tubing band, body weight, machine training and proprioceptive exercise. Shoulder range of motion (external rotation, flexion) were measured with goniometer and muscle strength (flexion, adduction, internal rotation) were measured with dynamometer. At 6momths, external rotation ROM was 50° (unaffected side 60°), and flexion almost recovered at 3 months. Muscle strength was gradually increased to 6.2kg, 15.7kg, and 27.0kg in flexion, while internal rotation The pain remained slightly after 9 months. The present results suggest that ROM exercise and strengthening exercise increase the muscle power and ROM, and decrease the pain.

Kaposi’s sarcoma is one of the first recognized in HIV infection even patient can develop KS in any disease stage. Moreover, the oral cavity may be the first site of Kaposi’s sarcoma and oral mucosa involvements of KS in HIV positive are very critical because it had a higher death rate than those who having exclusively cutaneous manifestations of the disease. Early detection of KS oral involvement is very important to prevent disease burden. This case is about a 48 years old male who was first discovered Oral Kaposi’s Sarcoma as HIV infection sign. He didn’t notice any other discomfort other than oral mucosa swelling.

Canalicular adenoma is an uncommon, benign salivary gland tumor. It has a significant predilection for occurrence in the minor salivary glands, with most cases occurring in the upper lip, followed by the buccal mucosa and palate. Rarely, canalicular adenoma can involve the major salivary glands, such as the parotid gland. Only a small number of cases of canalicular adenoma of the parotid gland have been reported in the literature. We report a rare case of canalicular adenoma on the left parotid gland of an 81-year-old man, and present a review of the literature.

The most common benign salivary gland tumor is pleomorphic adenoma. It affects major and minor salivary glands. Minor salivary gland tumors constitute <20% of all salivary gland neoplasms. Most minor salivary gland tumors occur on the palate. We present the case of a patient with pleomorphic adenoma that developed at a rare intraoral location. This patient presented to the Department of Oral and Maxillofacial Surgery of Seoul National University Dental Hospital.

The odontoma is a hamartomatous lesion consisting of enamel, dentin, pul and cementum. They are observed in the form of a tooth or as a mass of agglomerated teeth. Most of these occur during the period of development of normal teeth and grow to some extent. The fused tooth was the developmental abnormality of the teeth and the hard tissues of the adjacent teeth were combined. In general, these two lesions are not related, but two problems can occur together with systemic or local causes in the morphological differentiation period. We report a case of a 6 - year - old boy who visited our clinic for the eruption of a calcified mass in the mouth. The patient was diagnosed by the fusion of a odontoma and a mandibular permanent anterior tooth. And then, fused odontoma was removed surgically and the mandibular permanent anterior was restored by using composite resin. Calcified material was diagnosed as a composite tooth. After 6 months, the permannant teeth was satisfactory eruption and did not show any pathological problems in periapical radiography.

Pleomorphic adenoma is the most common benign tumor of the salivary glands. About 80-90% of pleomorphic adenoma occurs in the parotid gland and about 5-10% of them occur in the submandibular gland and sublingual gland. The rest proportion comprises the minor salivary glands. The palate is the most common area, followed by the lips and the cheeks. Pleomorphic adenoma of the submandibular gland shows clinically a slow-growing, painless mass found on submandibular aspect. In this case report, we report a case of pleomorphic adenoma of the right submandibular gland in a 63-year old female patient who was referred from the department of neurosurgery, due to the heterogenous mass detected by computed tomography (CT) and magnetic resonance imaging (MRI)
