We report a case of necrotizing arteritis involving the gallbladder. This case was clinically diagnosed as cholelithiasis with cholecystitis, and necrotizing arteritis was found in the surgically resected specimen. Vascular changes were similar to those seen in classic polyarteritis nodosa, involving medium-sized muscular arteries and characterized by fibrinoid necrosis and panarterial and periarterial inflammation varying from active to resolving stages. Acute cholecystitis is a rare initial clinical manifestation of the systemic vasculitis. If acute cholecystitis is found in the absence of obvious cause, careful examination is essential. Since steroid therapy improves the prognosis in the systemic vasculitis, clinicians and pathologists should be aware of this unusual lesion.

This case report describes a paraganglioma of the cauda equina in a 37-year-old man, as documented by light microscopy and immunohistochemistry. The patient experienced low back pain of 3 years duration, with the recent onset of sciatic pain and altered sensation in the right leg. Magnetic resonance imaging of L4 vertebral level revealed an ovoid, solid mass in the cauda equina. The mass was measured 1.5 cm in the greatest diameter. The histologic appearance was characterized by organoid pattern with clusters of chief cells (zellballen). Immunohistochemically, tumor cells are positive for keratin, epithelial membrane antigen, vimentin, neuron specific enolase and chromogranin.

3.A Case of Congenital Absence of the Inferior Rectus Muscle.
Journal of the Korean Ophthalmological Society 2006;47(5):852-857
PURPOSE: To report a patient with isolated congenital absence of the right inferior rectus muscle. To our knowledge, this is the first case reported in Korea. METHODS: A 6-year-old girl presented with an anomalous head posture of 15 degrees head tilt. She had 45delta right hypertropia, 15delta A-pattern exotropia and a marked underaction of the right inferior rectus. At the time of the surgery, forced duction test of the right eye showed no limitation and the inferior rectus muscle was found to be absent. Inferior transposition of the horizontal rectus muscles was more approximated to each other than that described in the classic Knapp operation. This was carried out while the right medial rectus muscle was simultaneously resected 2mm for correction of the exotropia. RESULTS There was significant improvement in infraduction at 6 months postoperative with only a residual 6delta exotropia in primary position. CONCLUSIONS: Absence of the inferior rectus showed hypertropia with A pattern exotropia. It did not bring about contracture of the superior rectus muscle or amblyopia. The outcome of the modified Knapp procedure was satisfactory.

Hemimegalencephaly is an uncommon sporadic congenital malformation of the central nervous system characterized by enlargement of one cerebral hemisphere with cranial asymmetry, hemiparesis, epilepsy, and mental retardation. This report deals with a 12-month-old girl with intractable seizure and developmental delay, who revealed hemispheric asymmetry and enlarged right cerebral hemisphere. MRI scan revealed asymmetric enlargement of right cerebral hemisphere with lissencephaly and multifocal calcification. She underwent right frontal lobectomy and parietal cortical resection, but died of complication of surgery. Histological features included loss of cortical lamination, large atypical neurons, neuronal heterotopia, and astrocytosis with dystrophic calcification. The heterotopic neurons in the white matter were suggestive of aberrant neuronal migration.

Primitive neuroectodermal tumors (PNET) of the ovary are rare tumors with an exclusive or almost exclusive malignant neuroectodermal composition, and are generally regarded as a monodermal expression of an ovarian teratoma. The tumors are basically identical with the lesions of the same name occuring typically in the central nervous system of children. These tumors consist chiefly of undifferentiated small cells resembling neuroblasts. There are also mature, well- differentiated neuroectodermal cells, such as astrocytes and ependymal cells. We report a case of ovarian PNET with glial and neuroblastic differentiation and focal teratomatous foci of non-neural tissue in a 17-year-old female.

7.Papillary Serous Cystadenoma of Borderline Malignancy Arising from a Paramesonephric Parovarian Cyst: A case report.

Primary malignant parovarian epithelial tumors are extremely rare, with only 56 cases previously reported in the world literature. Most parovarian epithelial tumors are of paramesonephric (Mullerian) origin. In this article, we report the first case in the Korean literature of papillary serous cystadenoma of borderline malignancy from paramesonephric parovarian cyst. This case presented here is of particular interest since this neoplasm is rare. A 48-year-old female underwent a hysterectomy with bilateral adnexectomy and pelvic lymph node dissection for a cystic tumor of the right parovarian area. The tumor, measuring 13 cm in diameter, was apart from the ovaries, fallopian tubes and uterus. The cyst wall had well-developed smooth muscle layers. The cyst was lined with mildly atypical ciliated and non-ciliated low columnar cells compatible with those of paramesonephric origin. From the inner surface of the cyst several cauliflower-like structures projected into the lumen. They were of a predominantly papillary architecture covered by atypical epithelial cells with piling-up and occasional glandular growth. No destructive stromal invasion was identified.
