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.

Arteriovenous malformation of the uterus is rarely encountered. It is potentially lethal because of profuse, uncontrollable bleeding at the time of diagnostic dilatation and curettage. To our knowledge, only 38 cases of localized uterine arteriovenous malformation have been reported in English and Korean literature. Recently we experienced a case of uterine arteriovenous malformation in a 28-year-old multiparous woman. Under the clinical impression of uterine tumors or arteriovenous malformation, a total hysterectomy was done. Gross examination demonstrated a vascular nature of the mass in the posterior wall of the fundus. Microscopically, there was an ill-defined mass composed of numerous irregular, anastomosing large vessels with various diameters.

An unusual pattern of focal involvement of lymph nodes by Hodgkin's disease is described using the name Interfollicular Hodgkin's Disease. It is characterized by florid reactive follicular hyperplasia which overshadows involvement of the interfollicular zones by Hodgkin's desease. The importance of interfollicular Hodgkin's disease rests on its misdiagnosis as a benign lesion. We report a case of interfollicular Hodgkin's disease in a 34-year-old female patient in the inguinal area. The lymph nodes showed reactive follicular hyperplasia. The focal interfollicular spaces were invaded by Hodgkin's disease. The Reed-Stemberg cells stained positively with CD15 and CD30 antibody in the immunohistochemical stain. An in situ hybridization study looking for EBV was negative in these R-S cells.

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.

The dysplastic nevus is a rare form of melanocytic nevus in Korean people. During the past 5 years the authors experienced 5 cases in the St. Mary's Hospital and Kang Nam St. Mary's Hospital. The criteria and the histologic findings of dysplastic nevi are debated in the western literature. Clinically, all cases were greater than 5 mm in size with ill defined irregular borders and irregularly distributed pigmentation. Histopathologically, all cases showed numerous discrete individual nests of melanocytes located in the dermoepidermal junction and the papillary dermis and were characterized by extension of dermoepidermal component of the nevus at the "shoulder" beyond the dermal component of the nevus. There was no cytologic atypia of nevus cells in all cases. Our cases lacked personal or family history of malignant melanoma. Therefore, we believe our cases are nonfamilial, sporadic and benign nevi with no prognostic significance. A brief review of the literature and a discussion on the term "dysplastic" and clinicopathologic correlation are made.

Gatric duplication is a rare congenital anomaly. Thus for about 90 cases of gastric duplication have been recorded in the literature. It is less frequent than small intestinal or eosphageal duplication, and accounts for only 3.8% of all gastrointestinal tract duplication. Most gastric duplications are seen during the first year of life. Palpable abdominal mass and gastric outlet obstruction in infancy are most common presentation. We experienced a case of non-communicating gastric duplication. A 12-year-old girl visited St. Mary's Hospital because of indigestion, intermittent vomiting, and left upper quandrant pain for about 40 days. She have had intemittent abdominal pain with concomitant increased level of amylase since 5 years old. Physical examination showed a hen's egg sized palpable mass on left upper quadrant of the abdomen. Upper GI series and barium enema revealed only indentation of duodenal C-loop, and sonogram and abdominal CT demonstrated isolated cystic mass along the greater curvature of gastric antrum. She had taken an operation under the impression of pancreatic pseudocyst. Operation revealed a cystic mass, located along the greater curvature. There was no pathologic change in the pancreas. Microscopic findings of the cyst wall revealed normal gastric mucosal lining and common muscle layer, shared with gastric antral muscle layer.

BACKGROUND: The purpose of our study was to evaluate the functional and radiologic outcomes of additive augmentation sutures through rotator cuff for proximal humeral fractures stabilized locking plate in elderly patients. METHODS: We enrolled 74 patients over the age of 60 years who received internal fixation using locking plates for proximal humeral fractures. Of these, 50 patients had additive augmentation sutures through rotator cuff. The mean age at the time of surgery was 72.1 years (range, 60-89 years), and the mean follow-up period was 17.5 months (range, 12-62 months). The humeral neck-shaft angle and humeral head height were used as radiological markers to assess the effect of additive augmentation sutures through rotator cuff. We allocated the patients who received additive augmentation sutures into group A and those who did not into group B. RESULTS: At the final follow-up, the mean Korean Showlder Society score and Constant scores were 88.96 +/- 12.1 and 86.6 +/- 11.9, respectively, in group A and 86.21 +/- 11.8 and 85.3 +/- 11.7, respectively, in group B (p=0.368, 0.271). At the final follow-up, the mean loss in humeral neck-shaft angle from the time of immediate postoperative measurement was 1.6degrees in group A and 4.8degrees in group B, whereas the mean loss in humeral head height was 0.82 mm in group A and 0.52 mm in group B (p=0.029, 0.178). CONCLUSIONS: The surgical outcomes of internal fixation using locking plates for proximal humeral fractures were clinically and radiologically good in elderly patients over the age of 60 years without any observable complications. Further, the loss of humeral head shaft angle at the final follow-up from its initial postoperative measurement was significantly smaller in patients who received an additive augmentation suture than in those who did not. Thus, we conclude that augmentation sutures are a beneficial option for elderly patients that clinicians can consider at the time of surgical decision making.

BACKGROUND: Management of massive rotator cuff tears can be challenging because of the less satisfactory results and a higher retear rate regardless of the use of open or arthroscopic repair technique. METHODS: We retrospectively analyzed 102 cases of massive rotator cuff tear treated with either open or arthroscopic repair. Open repair was performed in 38 patients; and arthroscopic repair, in 64 patients. The mean age at the time of surgery was 59.7 years in the open group and 57.6 years in the arthroscopic group. RESULTS: The Constant score increased from the preoperative mean of 55.9 to 73.2 at the last follow-up in the open repair group and from 53.8 to 67.6 in the arthroscopic repair group (p<0.001 and <0.001, respectively). The University of California at Los Angeles (UCLA) score increased from a preoperative mean of 17.7 to 30.8 at the last follow-up in the open group and from 17.5 to 28.7 in the arthroscopic group (p<0.001 and <0.001, respectively). No statistically significant difference in the Constant and UCLA scores was observed between the two groups at the last follow-up (p=0.128 and 0.087, respectively). Retear was found in 14 patients (36.8%) in the open group and 39 patients (60.9%) in the arthroscopic group (p=0.024). CONCLUSIONS: Open and arthroscopic repairs of massive rotator cuff tears may provide satisfactory clinical results with no significant difference. However, a significantly lower retear rate was observed for the open repair group compared with the arthroscopic repair group.

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.
