The authors analyzed 5 cases of renal carcinomas confirmed by operation and pathologically, which wereselected from all the cases of selective angiography performed recently at the department of radiology, Busan National University Hospital. The result obtained were as follows; 1. Among the 5 cases of malignant tumors of thekidney, 4 cases were renal cell carcinomas, and 1 case was transitional cell carcinoma. 2. In the sexdistribution, male to female was 3:2. And all cases were over 51 years of age. 3. All the 5 cases were discoveredat the left kidney; 1 case, in upper pole; 2 cases, in mid-portion; and 2 cases, in lower pole. 4. Clinicalmanifestations were hematuria in all 5 cases; flank pain in 4 cases. But no palpable mass was demonstrated in anycases. 5. The renal angiographic findings; Of 4 cases of renal cell carcinomas, 2 cases revealed markedhypervascularity, 1 case mild hypervascularity with multiple mulbery-like aneruysms, and 1 case avascularity withwell demarcated margin. 1 case of transitional cell carcinoma showed hypovascularity with perivascular pooling anddisplacement of the upper dorsal branch of renal artery.

Benign solitary schwannoma of the chest wall is a rare disease of nerve sheath origin A 43-year-old female patient was admitted to our hospital for right upper quandrant pain Chest X-ray shows nonspecific finding, ultrasonography & CT scan revealed a solid tumor on the right lateral chest wall. On aspiration needle biopsy, this mass was turned out to be a schwannoma of the right lateral chest wall. This mass was excised surgically in an encapsulated state by right lateral thoracotomy. Histological section revealed a typical schwannoma, which is characterized by Antoni A and Antoni B tissues of high & low cellularity.

We experienced a case of 16-year-old female with verruciform xanthoma transformed from lesions of epidermal nevus syndrome. The biopsy specimen of yellowish brown to red verrucous papule on the right buttock showed 1) uniform and verrucous acanthosis without cytological atypia, 2) parakeratosis and hyperkeratosis,3) variable foci of superficial necrosis with crusting and microabscess in the granular layer, 4) rete ridge elongation and papillomatosis, 5) characteristic foam cells located within the papillary dermis, but not below the rete ridges. Our case was diagnosed verruciform xanthoma by histopathologic finding which occured as a secondary development in lesions of epidermal nevus syndrome.

Hypokalemic periodic paralysis (HOPP) is a rare disease characterized by reversible attacks of muscle weakness accompanied by episodic hypokalemia. Recent molecular work has revealed that the majority of familial HOPP is due to mutations in a skeletal muscle voltage-dependent calcium-channel: the dihydropyridine receptor. We report a 13-yr old boy with HOPP from a family in which 6 members are affected in three generations. Genetic examination identified a nucleotide 3705 C to G mutation in exon 30 of the calcium channel gene, CACNA1S. This mutation predicts a codon change from arginine to glycine at the amino acid position #1239 (R1239G). Among the three known mutations of the CACNA1S gene, the R1239G mutation was rarely reported. This boy and the other family members who did not respond to acetazolamide, showed a marked improvement of the paralytic symptoms after spironolactone treatment.

Orbital neuroblastoma is the most common childhood metastatic malignant tumor almost always originating from the adrenal medulla; orbital primary origin is very rare. The authors experenced a case of orbital neuroblastoma. The patient was 3 year old Korean female child who was in apparently good health and no abnormalities noted of physical examminations when she developed ecchymosis of right lower lid. About two week later, she quickly developed a growing mass in the right lower orbital soft tissue. The mass was removed and his topathologically diagnosed as neuroblastoma. Radiotherapy was recommended. About 4 months bter, the patient was readmitted because of recurrence of orbital mass 3t the same site. At surgery, tumor was found invading inner and flooe wall of the orbital bone. The patient died of poor course of the disease, about one year after the onset of symptoms. It was suggested that this case was represented metastatic orbital neuroblastoma on histopathological base, but authors were unable to determine the primary site. A brief review of the related literatures is present.

Malignant myoepithelioma (myoepithelial carcinoma), is a very rare malignant epithelial neoplasm accounting for less than 1% of all salivary gland tumors and has an intermediate malignant potential. We report a case of malignant myoepithelioma arising in the left parotid gland in a 54-year-old man, which was difficult to differentiate from pleomorphic adenoma and other malignant salivary gland neoplasms. Fine needle aspiration cytology of the parotid gland showed cellular smear, composed of overlapped sheets and clusters or individually scattered tumor cells without any acinic or ductal structures. The tumor cells were rather uniform, with distinct cell borders and moderate amount of cytoplasm. The eccentrically located nuclei were oval to round and pleomorphic and showed prominent nucleoli. A few clear cells were noted in the cellular aggregates. Metachromatic matrix was seen between individual tumor cells in a lacelike fashion, resembling pleomorphic adenoma. According to the immunohistochemical staining, we recognized that the component cells are myoepithelial in nature, showing reactivity for the S-100 protein, vimentin, and actin.

Biliary atresia (BA) is an uncommon neonatal surgical disease that has a fatal outcome if not properly treated. The survival rates of the patients with native liver after Kasai's operation in countries outside Japan are not so good. We reviewed the results of 22 cases of biliary atresia treated in Kosin University Hospital between October 1987 and March 2001. There were 13 males and 9 females aged from 21 to 106 days (mean 52 days). There were 3 cases of Type I (13.6%), and 3 of Type II (13.6%), and 16 Type III (72.7%). The operative methods were resection of the common bile duct remnant and cyst followed by Roux-en-Y hepaticojejunostomy in 3 cases for Type I BA; Kasai I in 15 cases, Kasai II in 1 case, and Ueda's operation in 3 cases for Types II and III BA. There was no death within the first 30 days after operation. We were able to follow 21 of the 22 patients (95.4%) for more than 5 years. The actual 5 year survival rate (YSR) was 40.9%. One Type I case received a living-related liver transplantation at 6 years of age because of the multiple intrahepatic stones and liver cirrhosis. Five YSR after biliostomy group (Kasai II and Ueda op.) was 75% (3/4) while that of Kasai I was 20% (3/15). One case had no bile duct in the resected fibrotic plaque on microscopic review and died 8 months after Kasai I operation, would have been a strong candidate for early liver transplantation. From the above result, our conclusions are as follows; (1) early liver transplantation should be considered for cases of no bile duct after pathologic examination of the resected specimen, (2) measures to prevent postoperative cholangitis and prevention of postoperative liver cirrhosis are needed, (3) liver transplantation program should be available for failed cases.
