Balloon cell malignant melanoma (BCMM) is a rare histologic variant of malignant melanoma, which is composed either predominantly or entirely of large clear or foamy cells. The incidence of balloon cell malignant melanoma is about 0.15% of all cutaneous malignant melanomas. Recently, we experienced a case of cutaneous balloon cell malignant melanoma in the right lower abdomen with right inguinal and both axillary lymph node metastasis in a 56-year-old man. The cutaneous lesion was 4.5 3.5 cm in size, a well-demarcated black nodular mass, involving abdominal skin and subcutaneous tissue. The tumor was histologically composed of two types of tumor cells: predominant clear cell and focal, pigmented spindle cell. The nodal lesion was composed entirely of clear cells. Both clear and spindle cells showed positive reaction for S-100 protein and HMB-45 on immunohistochemistry.

Synovial sarcoma is one of the most common malignant soft tissue tumors in paraarticular regions. However, it is very rare to occur without any apparent relationship to synovial or articular structures. We report a case of synovial sarcoma manifested as a subcutaneous nodule in the upper lip. A 12-year-old boy complained of a palpable tender mass in the upper lip for several months. Under the impression of a benign soft tissue neoplasm, surgical excision was done. The mass, 1.5 cm in maximum diameter, was easily separated from surrounding tissues. Microscopically, this tumor showed a characteristic biphasic pattern of synovial sarcoma. On immunohistochemical and ultrastructural studies, the tumor cells showed evidence of epithelial differentiation. There was no evidence of joint-related, primary lesions or metastatic foci. This report describes a case of synovial sarcoma arising in very unusual location and size for histologically typical synovial sarcoma.

We report a case of 50-year-old man with hyalinized hemangioma of the liver. This tumor was detected incidentally during surgical operation for gall stone and was preoperatively diagnosed as intrahepatic stone. A 2.5 2 cm sized gray to white hard mass was found in the left lobe of the liver. Histologically, the tumor was composed of dense collagenous tissue with marked hyalinization, calcification, and ossification admixed with scattered sclerotic vessels. Abundunt elastic fibers were noted in the hyalinized tissue. Totally hyalinized hemangioma is very uncommon and could be erroneously diagnosed as a malignant tumor by preoperative radiologic examination.

Chronic fatigue of the respiratory muscles has contributed to the decreased ventilatory capacity and reduced excercise tolerance of individuals with COPD, especially in kyphoscoliosis. Nasal mask BiPAP has been shown to be useful for the patient with nocturnal muscle fatigue and COPD. A 35-year-old man with severe kyphoscoliosis was admitted to ICU due to acute respiratory failure. He had been diagnosed of COPD and had been intubated with mechanical ventilatory support for 7 times. This time he was intubated with ventilatory support, too, in ICU and readmitted to the ICU for severe hypoxemia and hypercarbia from general ward. Thereafter he refused the intubation. Nasal mask BiPAP ventilatory support system was applied and IPAP, EPAP level being adjusted to the 12, 4 cmH2O under monitoring vital signs and arterial blood gas analysis. His condition was improved and discharged home with support of nasal mask BiPAP system after 33 day-stay in the ICU.

Hepatoblastoma is a primary embryonic liver tumor usually found in children. It extremely rarely occurs in adults. We report a case of hepatoblastoma in a 56 year old man with chronic hepatitis B of 10years duration. Laboratory investigation of the patient on admission showed a marked elevation of alpha-fetoprotein in serum. Ultrasonography and Computerized tomography scan revealed a primary tumor, 6x7cm in size, in the right lobe. The tumor removed by a right lobectomy. Complete removal of the tumor is the treatment which is potentially curative provided that lesion is confined within the liver capsule. The literature revealed and a case of this tumor reviewed.

Although spontaneous bacterial peritonitis is a frequent complication in the childhood nephrotic syndrome, it is very rare in adults with nephrotic syndrome. It frequently develops when the patients are either in relapse or receiving steroid therapy at the time peritonitis is diagnosed. We report an unusual case of a spontaneous bacterial peritonitis as the presenting feature in a 15-year-old male patient with nephrotic syndrome. He presented with diffuse abdominal pain and distension for 15 days. Abdominal paracentesis revealed the diagnostic laboratory findings of peritonitis, and the bacterial culture of the ascites showed a mixed growth of Escherichia coli and Pseudomonas aeruzinosa. His serum albu- min level was 1.6gldL and the amount of 24 hours proteinuria was 21.0g/day. Although he was treated with adequate antibiotics for 3 weeks, the peritonitis was more aggravated. We decided to insert a catheter into the peritoneal cavity for continuous drainage of the intractable ascites. Two weeks after drainage, the peritonitis improved as the peritonitis subsided, the proteinuria disappeared completely without a steroid therapy. Six months after spontaneous remission, the proteinuria have recurred, and the kidney biopsy then showed focal segmental glomerulorsclerosis.

Postoperative atrial arrhythmia after thoracotomy is relatively common, with a reported incidence ranging from 8% to 30%. These arrhythmias may cause hypotension, congestive heart failure and lengthen the period of postoperative hospitalization. The most important precipitating factor is atrial dilation and identified risk factor is an advanced age of the patient. The effect of various prophylactic regimens to reduce atrial arrhythmias is controversial. We report a case of postoperative atrial fibrillation in a 73 year-old female patient undergoing repair of esophageal hiatal hernia.
