A 14-year-old boy was admitted to the hospital due to a single episode of afebrile seizure and four hours of impaired consciousness. Three months prior to admission, he had a history of bilateral uveitis. Cerebrospinal fluid analysis revealed a mild elevation in white blood cell count. Cranial magnetic resonance imaging and contrast-enhanced scans showed multiple abnormal signals in both cerebral hemispheres, with punctate and nodular enhancement. Susceptibility-weighted imaging revealed multiple punctate hemorrhages within lesions in the bilateral frontal and left parietal lobes, suggestive of vasculitis. Brain biopsy demonstrated inflammatory granulomatous lesions. No secondary causes were identified, and the final diagnosis was granulomatous primary central nervous system vasculitis. The patient's condition improved after treatment with methylprednisolone sodium succinate and mycophenolate mofetil. This report describes a rare case of granulomatous central nervous system vasculitis in a child and provides valuable insights for the diagnosis and treatment of this disease.

Inflammatory myofibroblastic tumor is a rare tumor of mesenchymal origin. A case of intratracheal inflammatory myofibroblastic tumor in a male child was reported. The clinical characteristics, diagnosis, treatment and prognosis of the disease were reviewed based on the literature, and a differential diagnosis between inflammatory myofibroblastic tumor and hamartoma was performed to ultimately confirm the nature of the tumor in the child.

Eosinophilic granuloma, a rare disease, has various clinical manifestations and no specific X-rays features and is thus easily misdiagnosed. This paper reports a case of multifocal eosinophilic granuloma of jaw with long-term follow-up. The patient initially presented with periodontal tissue destruction.The diagnosis, treatment and prognosis of multifocal eosinophilic granuloma of jaw were discussed in combination with the literature to alert this disease in clinical practice.

OBJECTIVES: This study aimed to determine the prevalence of odontogenic cysts, tumors, and other lesions among reports in the archives of the Department of Oral and Maxillofacial Surgery at the Faculty of Dentistry affiliated with Kocaeli University collected over a four-year period.MATERIALS AND METHODS: In this retrospective study, patient records from the archive of the Department of Oral and Maxillofacial Surgery from 2014 to 2018 were reviewed. Patient demographic information (age and sex) and lesion location were recorded and analyzed.RESULTS: From a total of 475 files reviewed, odontogenic cyst was confirmed in 340 cases (71.6%), and odontogenic tumor was confirmed in 52 cases (10.9%). Regarding odontogenic cyst type, the most common was radicular cyst (216 cases), followed by dentigerous cyst (77 cases) and odontogenic keratocyst (23 cases). Among odontogenic tumors, the most frequent was odontoma (19 cases), followed by ossifying fibroma (18 cases) and ameloblastoma (9 cases). Giant cell granuloma was also reported in 35 cases.CONCLUSION: The distribution pattern of odontogenic cysts and tumors in our retrospective study is relatively similar to that reported in the literature. Complete clinical reports for final diagnosis of these lesions and routine follow-up examinations are very important for treatment.

Orocutaneous fistulas, or cutaneous sinuses of odontogenic origin, are uncommon but often misdiagnosed as skin lesions unrelated to dental origin by physicians. Accurate diagnosis and use of correct investigative modalities are important because orocutaneous fistulas are easily confused for skin or bone tumors, osteomyelitis, infected cysts, salivary gland fistulas, and other pathologies. The aim of this study is to present our experience with a patient with orocutaneous fistulas of odontogenic origin presenting as recurrent pyogenic granuloma of the cheek, and to discuss their successful treatment.

Orbital tuberculosis is a rare form of extrapulmonary tuberculosis, even in endemic areas. It may involve the soft tissue, lacrimal gland, periosteum, or bones of the orbital wall. We present a case of orbital tuberculosis on the lower eyelid. An 18-year-old woman with no underlying disease visited our clinic for evaluation of an oval nodule (1.5× 1.2 cm) on the right lower eyelid. Incision and drainage without biopsy was performed 2 months ago in ophthalmology department, but the periorbital mass had deteriorated, as the patient had erythematous swelling, tenderness, and cervical lymphadenopathy. Visual acuity was normal; there were no signs of proptosis, diplopia, or ophthalmoplegia. Computed tomography revealed a small abscess cavity without bony involvement. We performed an excision and biopsy through a percutaneous incision under local anesthesia. Histological examination revealed a granuloma and was diagnosed as orbital tuberculosis. The patient was additionally treated with anti-tuberculosis therapy for 6 months and recovered without complication or recurrence by 7 months. Orbital tuberculosis occurs in patients with or without associated pulmonary tuberculosis, and should be considered as a differential diagnosis in patients with inflammatory orbital disease and an orbital mass. If recurrence occurs despite adequate initial treatment, we recommend an additional examination and excisional biopsy.

PURPOSE: This study reviewed the common conditions associated with displacement of inferior alveolar nerve canal. MATERIALS AND METHODS: General search engines and specialized databases including Google Scholar, Pub Med, Pub Med Central, Science Direct, and Scopus were used to find relevant studies by using keywords such as “mandibular canal”, “alveolar canal”, “inferior alveolar nerve canal”, “inferior dental canal”, “inferior mandibular canal” and “displacement”. RESULTS: About 120 articles were found, of which approximately 70 were broadly relevant to the topic. We ultimately included 37 articles that were closely related to the topic of interest. When the data were compiled, the following 8 lesions were found to have a relationship with displacement of mandibular canal: radicular/residual cysts, dentigerous cyst, odontogenic keratocyst, aneurysmal bone cyst, ameloblastoma, central giant cell granuloma, fibrous dysplasis, and cementossifying fibroma. CONCLUSION: When clinicians encounter a lesion associated with displaced mandibular canal, they should first consider these entities in the differential diagnosis. This review would help dentists make more accurate diagnoses and develop better treatment plans according to patients' radiographs.
