박원홍,임원봉,김지선,김상우,Zheng Hui,Kou Ni,전상미,박지일,최홍란,김옥준 대한구강악안면병리학회 2012 대한구강악안면병리학회지 Vol.36 No.6
Ameloblastic fibro-odontoma has been defined as a lesion similar to ameloblastic fibroma by WHO, as it shows inductive changes which forms enamel and dentin. Ameloblastic fibro-odontoma is a very rare mixed dentition tumor in children, and the symptom shows indolent edema in maxillary and mandibular molar area. The prevalence is two times higher in male than in female, and two times higher in maxilla than in mandible. Radiologically, it shows clear border and characteristics of both fibroma and odontoma histologically. This review reports a case that a 4-year old female visited in dental clinic of this school for edema as chief complaint in Feb, 2012. Emergency surgical curettage was performed right after initial diagnosis as odontoma, then confirmed diagnosis as Ameloblastic fibro-odontoma after biopsy. Currently, after 6 month, no sign of recurrence can be seen. Ameloblastic fibro-odontoma is very rare mixed dentition tumor. Moreover, as it is the case of female maxilla, this case is worth of publishing. Furthermore, accurate diagnosis of Ameloblastic fibro-odontoma is difficult. This review is published for accurate diagnosis through differential diagnosis of several important mixed dentition tumors.
Malignant Oncocytoma of the Orbit: A Case Report
박원홍,이인호,송창준,김다미,이성복,김진만 대한영상의학회 2013 대한영상의학회지 Vol.69 No.6
Malignant oncocytoma of the orbit is extremely rare. A 76-year-old man presented with a 10-year history of a mass in the left orbit. Facial computed tomography revealed a large homogeneously enhancing mass. Magnetic resonance images showed a mass with isosignal intensity on a T1-weighted image and low signal intensity on a T2-weighted image. No restricted diffusion was observed on diffusion weighted imaging and apparent diffusion coefficient mapping. The patient underwent an incisional biopsy, and histopathological review revealed a malignant oncocytoma that likely originated in the caruncle of the left eye.
Pineal Gland Metastasis as the Initial Presentation of Squamous Cell Lung Cancer: A Case Report
박원홍,송창준,김다미,이인호 대한영상의학회 2014 대한영상의학회지 Vol.71 No.3
The pineal gland is an unusual site for brain metastasis, and a solitary pineal gland metastasis is rare. A 71-year-old man presented with dizziness, gait disturbance, and memory impairment. Brain computed tomography revealed a solitary hyperdense mass with central calcification in the pineal region and obstructive hydrocephalus. Brain magnetic resonance images showed a heterogeneously enhancing mass with intratumoral calcification and microcysts. Metastatic squamous cell carcinoma was diagnosed following an endoscopic biopsy. A systemic review revealed that the primary site of the carcinoma was the lung. Although rare, metastasis should be considered in the differential diagnosis of pineal region tumors, especially in elderly patients with a pineal tumor that presents unusual imaging findings.
