We report a case of 53-year-old man with plasmacytoid transitional cell carcinoma of the urinary bladder, which may be confused with plasmacytoma. The patient initially presented with gross hematuria and dysuria for two months. Cystoscopy and radiologic studies revealed multiple intraluminal protruding masses on the urinary bladder invading perivesical fat tissue. After urinary cytologic examination and cystoscopic biopsy, radical cystectomy and pelvic lymph node dissections were done. Urine cytology showed single cells and poorly cohesive cells with round eccentric nuclei, bi-or multi-nucleation, indistinct nucleoli, coarse chromatin, and abundant basophilic cytoplasm within relatively clear background. The cytologic findings of tumor cells were similar to the plasma cells seen in plasmacytoma. The tumor of the bladder was composed of discohesive, individual cancer cells with diffuse pattern that simulated lymphoma or plasmacytoma. Immunohistochemical and electron microscopic studies clearly established the epithelial nature of the neoplasm. Recognition of this plasmacytoid type of transitional cell carcinoma of the urinary bladder can avoid the misdiagnosis.

Hypernephroma comprises about 85-90% of renal malignancy in adults. The natural course of hypernephroma isvery diverse and unpredictable from abrupt explosive growth with wide spread metastasis to asymptomatic slowgrowth for several years. Reports from aliens indicated that hypernephroma with histopathological papillary growthpattern has better prognosis and more frequently hypovascular on renal angiography and less echogenic onultrasonography than non-papillary hypernephroma. Reviewed here retrospectively all the patients who were admittedand diagnosed as hypernephroma histopathologically at the Severance Hospital from March, 1973 through September,1984, in respective of angiographic vascularity, ultrasonographic echogenicity, histopathologic cell type andgrowth pattern, and following results were obtained. 1. The incidence of calcification in hypernephroma was 7cases out of 53 cases(13%). The incidence of hypernephroma according to cell type was clear cell type 20 cases(56%), mixed cell type 11 cases (31%), granular cell type 4 cases (11%), sarcomatous cell type 1 case(2%). Theincidence of hypernephroma according to growth pattern was papillary growth pattern 14 cases(45%) andnon-papillary growth pattern 17 cases(55%). 2. Renal angiographically, hypervascular hypernephroma was 19cases(73%), hypovascular hypernephromas was 6 cases(23%), all of which showed abnormal marginal vessels. 3.Angiographically hypervascular hypernephroma had high incidence of predominantly high echogenicity andangiographically hypervascular hypernephroma had high incidence of predominantly low echogenicity. 4. Clear celltype hypernephroma had high incidence of predominantly low echogenicity on ultrasonography. 5. Predominantly lowechogneic hypernephroma had high incidence of papillary growth pattern and predominantly high echogenichypernephroma had high incidence of non-papillary growth pattern. In summary, clear cell type hypernephroma hadhigh incidence of hypovascularity angiographically and hypovascularity on angiography was correlated withpredominantly low echogenicity on ultrasonography, and predominantly low echognicity had high incidence ofpapillary hypernephroma which was reported to have more good prognosis than non-papillary hypernephroma. So, itcan be suggested that if a hypernephroma show hypovascularity on angiography or predominantly low echogenicity onultrasonography, it has a good prognosis than hypervascular or predominantly high echogenic hypernephroma.

Open discectomy is one of usual treatment for herniated intervertebral disc. We may expect the reduction of height of intervertebral disc due to decreased volume by partial resection of herniated disc. But the effect of decreased height of intervertebral disc space to posterior joint and spinal canal has not been identified, and the correlation between the amount of reduced height and the changes of range of motion has been undetermined. Thus, we analyzed radiologic changes of disc height and segmental motion by the flexion-extension view in 20 patients who had undergone discetomy for prolapsed intervertebral disc from June 1989 to January 1991 who could be followed up for 3 years or more. As a result, lumbar discetomy associates with 1) significant decrement of disc height (average 14%), 2) decreased disc motion of involved segment without hypermobility (average 34%), 3) hypermobility of adjacent segment, 4) and posterior facet overriding consistent with recurred low back pain.

Intraspinal tumors in children are of especially interest to orthopaedic surgeons for two reasons; First, musculoskeletal abnormalities, are often treated for long periods before the correct diagnosls is suspected; Second, important orthopaedic problems are encountered in almost everychild treated for intraspinal tumor, not only during the immediate postoperative management but all through subsequent growth. We report a case presentation of the intraspinai tumor, dermoid cyst, successfully treated with operation.

Colorectal cancer during pregnancy is rare but the trend for women to delay pregnancy until later in life may result in increased incidence of colorectal cancer during pregnancy. The most common symptoms are rectal bleeding, abdominal discomfort, abdominal distension, anorexia, nausea, vomiting, constipation, anemia and weight loss. Rectal bleeding, if it is occurred, is often attributed to hemorrhoids, a common finding of pregnancy and many of these symptoms are commonplace in normal pregnancy. This delays diagnosis of colorectal cancer during pregnancy and leads to more advanced stage and poor prognosis compared to the general population. We experienced a woman at 27 weeks gestation who complained of low abdominal distention and was diagnosed of sigmoid colon cancer and underwent cesarean section and hemicolectomy at 30 weeks gestation, so we present it with brief review of literature."
