Multilocular cystic renal cell carcinoma is a distinct subtype of renal cell carcinoma with its pathological characteristics and good prognosis. Multilocular renal cysts and renal cell carcinoma with cystic change are important differential diagnoses. We report a case of multilocular cystic renal cell carcinoma in a 37-year-old woman who came to the hospital because of the right renal mass. The removed right kidney showed a 6x4 cm well defined cystic mass in the lower pole. On cut section there were multiple cavities in the mass, filled with serosanguineous fluid and focal yellowish solid area. Microscopically, these cysts were lined by a single layer of flat or cuboidal cells consisted of clear cytoplasm with small central nuclei. In some portions of the tumor, the clear neoplastic cells formed sheets within the septa or walls of the cysts.

In benign hyperproliferative epidermal diseases(eq. warts, psoriasis) and squamous carcinoma, some molecular markers of hyperproliferative keratinocyte such as cytokeratin 16 and PCNA were expressed predominantly. However, all healthy epidermis including the meatal epidermis are nonreactive to those molecular markers except some of thick skin. Recently, there are several reports which show unusal proliferative capacity around the annular region of the ear drum. Our study has concentrated on the characteristics of the differentiation in healthy deep meatal epidermis using immunohistochemistry with cytokeratins and PCNA. Our investigation has demonstrated that the deep meatal epidermis around the annular region in contrast to the other region of the meatus exhibited unusal proliferative capacity. This result suggests a pathology link such as invasion mechanism and hyperkeratinization between the cholesteatoma and deep meatal skin.

Neurilemmomas are well-encapsulated, benign, slow-growing tumors originating from Schwann cells of the nerve sheath surrounding cranial, peripheral, or autonomic nerves. Intraoral neurilemmomas are relatively rare and have a wide variety of morphologic and radiologic features. This makes differential diagnosis difficult, and only histopathological features can lead to a definitive neurilemmoma diagnosis. In this report, we present the case of a 30-year-old woman whose chief complaint was a solitary, nodular mass on the right floor of the mouth. After computed tomography and magnetic resonance imaging, we performed an incisional biopsy that showed the typical characteristics of a neurilemmoma. The mass was removed completely through an intraoral surgical approach. Despite losing a portion of the lingual nerve, the patient did not complain of any specific discomfort. Wound healing was uneventful and there were no signs or symptoms of recurrence.

PURPOSE: To evaluate the radiographic changes in distal radius fractures treated conservatively. MATERIALS AND METHODS: We reviewed 55 patients with a distal radius fracture treated by conservative treatment. Average age was 57.6 years. According to the AO classification, 17 were A2 fractures followed by C1 (13 cases), C2 (9 cases), C3 (7 cases), B1 (6 cases) and A3 (3 cases). Closed reduction and U-shaped splint were applied as initial treatment. Long arm cast followed by short arm cast were applied for intraarticular or metaphyseal comminuted fractures. Radial inclination angle, radial length and volar tilt angle in each radiograph were measured and evaluated by statistic analysis. Radiographic changes according to ages, comminution of metaphysis and fracture type were also evaluated. RESULTS: Radial inclination, radial length and volar tilt were 22.8degrees, 12.0 mm and 8.5degrees after closed reduction, 22.1degrees, 10.5 mm and 7.7degrees at casting, 20.1degrees, 8.7 mm and 4.5degrees at cast off, and 18.7degrees, 7.4 mm and 4.1degrees at last follow-up. All three values had statistical significances between casting and removal of cast (p<0.001, p<0.001, p=0.002). Radial inclination angle and radial length in the group over 60 years had statistical significances between casting and removal of cast, comparing with the group under 60 years (p=0.037, p=0.045). CONCLUSION: Loss of reduction was more prominent between 3 to 6 weeks after injury, especially in the group 60 years or older.

Intradural extramedullary (IDEM) tuberculoma of the spinal cord is uncommon entity and moreover, few reports have been documented on concurrent IDEM and intracranial tuberculomas. Authors report a case of IDEM spinal tuberculoma having intracranial lesion simultaneously. A 49-year-old woman suffered from paraparesis and urinary incontinence while being given medical treatment for tuberculous meningitis. Magnetic resonance imaging (MRI) revealed an IDEM mass lesion between the T1 and T2 spinal levels, and multiple intracranial tuberculous granulomas. Surgical resection of the IDEM tuberculoma followed by anti-tuberculous medication resulted in good outcome.
