    ABSTRACT: Spinal meningiomas of five or more vertebral segment long are very rare and also less common in younger patients. Under 50 years of age these tumors are more commonly genetical and have worse prognosis. A 25-year-old woman presented with back pain and progressive walking difficulty. An intradural extramedullary tumor extending from thoracal 9th to lumbar 2nd vertebral body was detected. The patient was operated and the tumor was totally removed. The histopathological diagnosis was angiomatous meningioma. Neurological symptoms and signs partially improved postoperatively. Interestingly, magnetic resonance imaging of this patient might easily be confused with ependymoma. Although we performed laminectomy and instrumentation, to maintain stability laminoplasty should be the first treatment modality for such a young patient.

    ABSTRACT: Idiopathic scrotal calcinosis is characterized by the presence of multiple firm nodules of scrotal skin. The nodular calcifications are typically found in the second decade of life. The lesions are seen as asymptomatic, round, firm papules. A 53-year-old man was admitted with painless, firm nodules within the scrotum. The lesions had begun to appear at the age of 23 years and some of them had become polypoid progressively over time. There was no trauma or previous surgical treatment. The serum levels of calcium, phosphorus, calcitonin, and parathyroid hormone were within normal limits. The polypoid masses were surgically excised. Histological examination of the cysts revealed dystrophic calcification of their keratin contents but no epithelial lining. To the best of our knowledge, this is the second case of scrotal calcinosis with polypoid appearance in the literature.

    ABSTRACT: Renal dysplasia is a disorganized development of the kidney because anomalous differentiation of the metanephrosis. Abnormalities of the collecting system are common. They include obstruction of the ureteropelvic junction, ureteral atresia and urethral obstruction. The case was a six months old female child with ultrasonografically detected right hydronephrosis and oligohydroamniosis at the 20 th week of gestation. She underwent an operation for bilateral hydroureteronephrosis at 1 month of age. There was no serious and related illness in family history and self-history. She underwent right nephrectomy at 6 months of age. The specimen included an atrophic nephrectomy material with lobulations and a dilated ureter. When sectioned, it was observed that the pericaliceal areas were dilated and the cortex-medulla border was obscured. On microscopic examination, the cortex was thin, contained rare small glomerules, primitive ducts and mononuclear cell infiltration were seen. A focus of cartilage was observed at the cortex-medulla junction. The case was diagnosed as renal hypoplastic dysplasia. During 4 months of follow-up, no complication was reported. This case is presented considering the uncommon occurence of renal dysplasia and its differential diagnosis from other congenital cystic renal malformations.

    ABSTRACT: Choroid plexus carcinoma which is a rare malign tumor of central nervous system. These tumors constitue 20-30% of the primary choroid plexus tumors and are more frequently situate in the lateral ventricle. Choroid plexus carcinoma is invasive and involves areas of necrosis and hemorrhage. Our case is a 4 year old girl who was admitted to university hospital presented with headache, stupor and lethargy. In cranial computerized tomography, a tumor was detected in right temporoparietal lob. Histopathologically the tumor cells were composed of branching papillary structures surrounding a fibrovascular core and infiltrate in brain parenchyma. Large areas of necrosis were detected within the tumor. High mitotic activity was also present. Tumor were not showed to react with mucicarmen, but diffuse reaction for S-100 and focal positive reaction for GFAP, pankeratin(Clone AE1/AE3) and CK7 were observed. Finally, the tumor was diagnosed as choroid plexus carcinoma. This case is presented here, because of its rarity and importance in differential diagnosis of papillary tumors of central nervous system.
