Dermatofibrosarcoma protuberans (DFSP) is a rare, distinctive cutaneous tumor, which consists of spindle shaped ceils arranged in densely packed interlacing bundles with the storiform or cartwheel pattern. Histologically, it resembles deep growing dermatofibroma, nodular fasciitis, neurofibroma and neural sheath tumors. DFSP is one of t.he connective tissue tumors which is difficult. to diagnose histologically as well as clinically. Recently, the immunochemical staining with a monoclonal antibody to CD34 is reported to give assistance in the clear differential diagnosis of DFSP from other fibrous or neural tumors. Herein, three cases of DFSP were stained by immunohistochemical staining with S-100 protein, vimentin, factor VIII and anti-CD34 antibody in order to assess the use of anti-CD34 in the differential diagnosis of DFSP.

Four cases of retinal detachment with macular hole and no posterior vitreoretinal connections were treated successfully by draining subretinal fluid externally, injecting sulfur hexafluoride gas into the vitreous cavity, and then keeping the patient in a prone position. And in all four cases, the retina remained attached during follow-up periods of 6 months or longer. This approach is simple, easy, and safe. Moreover, it brings good functional success because the macula is preserved. This approach must be the treatment of choice in retinal detachments with macular hole but without other breaks or vitreous adhesion.

Extramammary Paget's disease (EMPD) typically presents as an eczematous, eroded or crusted plaque. Only a few cases with depigmentation have been reported. We herein report a patient with a depigmented scrotal patch as the sole finding of EMPD. Since he had concurrent rectal cancer, we stained the tissue with gross cystic disease fluid protein-15 (GCDFP-15) and cytokeratin 20 (CK20) in order to differentiate primary/secondary EMPD. This case represents coincidental primary EMPD and rectal cancer, of which the initial features of EMPD were unusual.

A 49-year-old woman visited the clinic because of acute hepatitis and acute kidney injury with decreased urine output presenting microscopic hematuria and proteinuria. An abdominal computed tomography revealed a localized, hypoattenuated lesion in a hepatic lateral segment, and kidney biopsy showed oxalate crystal deposition with tubular necrosis. In addition, the patient's 24-hour urinary excretion of oxalate was increased. Her kidney and liver injury improved after sessions of hemodialysis, and urinary oxalate excretion was normalized. Major mutations in primary hyperoxaluria have not been proven. A full sequencing of target genes may be helpful to diagnose a rare form of primary hyperoxaluria.

OBJECTIVES: We conduct this study to investigate the common features between Attention Deficit Hyperactivity Disorder(ADHD) and epileptic patients compared to normal control. METHODS: Epileptic patients were recruited from the department of pediatic in Jesus Hospital. ADHD patients were recruited from the department of neuropsychiatry in Jesus Hospital. We excluded mental retardation or brain organic pathology. We use ADHD Diagnostic System and Korean-Child Behavior Checklist(K-CBCL) to assess features of ADHD. Electroencephalogram(EEG) of ADHD, epileptic patients and normal control were analyzed and compared. RESULTS: Compared to normal control group, inattention, reaction time deviation were increased in both ADHD and epilepsy group. EEG abnormalities(control 13.8%, epilepsy 97.1%, ADHD 40%) in three groups were reported. CONCLUSION: There are common features of ADHD and epileptic patients.

PURPOSE: To evaluate the efficacy of transcatheter arterial embolization(TAE) in children with blunt splenicinjury. MATERIALS AND METHODS: The results of transcatheter splenic arterial embolization in nine children whosuffered splenic injury after blunt abdominal trauma were retrospectively studied. This injury was demonstrated byCT, and the findings were evaluated according to the classification of Mirvis et al. ; two patients were grade 3and seven were grade 4. All were carefully observed in intensive care before embolization. TAE was performed if apatient satisfied the following criteria : (1) transfusion and/or fluid replacement required to maintainhemodynamic stability ; or (2) rapid Hb/Hct decrease ; or (3) both. Splenic function was subsequently estimatedaccording to the results of 99mTc-sulfur colloid scintigraphy and/or CT scanning. RESULT: TAE was suscessful inall nine children. Two were embolized with a coil only, three with gelfoam, and four with gelfoam and a coil.Seven were embolized in the main trunk of the splenic artery and others in both the main trunk and its branches.Splenic function was preserved in all nine children, during follow-up, none suffered rebleeding. CONCLUSION: TAEof the splenic artery can be a safe and effective nonsurgical approach to the management of blunt splenic injuryin children, and can preserve splenic function.

Pulmonary embolism is a not uncommon perioperative complication that results in substantial morbidity and mortality. However prompt diagnosis is difficult because clinical symptoms and signs of pulmonary embolism are not completely obvious. We report a case of severe pulmonary embolism on the first postoperative day of total abdominal hysterectomy in a patient transfused preoperatively for iron deficiency anemia caused by menorrhagia. We diagnosed pulmonary embolism by echocardiogram and chest spiral computerized tomography and the patient was moved to the intensive care unit. Tissue plasminogen activator was given and followed by continuous heparin infusion but the patient did not improve. He developed multiple organ dysfunction syndrome and died on the seventh postoperative day.

PURPOSE: The incidence of secondary malignancies in hematologic patients is known to be higher than it is in other patients. However, the characteristics of secondary malignancy and surveillance have not yet been established for colorectal cancer in leukemic patients. METHODS: From 1995 to 2007, 6,030 patients who were diagnosed with acute myeloid leukemia (AML), acute lymphoid leukemia (ALL), chronic myeloid leukemia (CML), chronic lymphoid leukemia (CLL), and multiple myeloma (MM) were enrolled in this study. Among them, 9 patients were diagnosed with colorectal cancer at St. Mary's Hospital and were analyzed retrospectively. RESULTS: Three of the 2,570 patients with AML, 1 of the 1,158 patients with CML, 2 of the 83 patients with CLL, 2 of the 422 patients with MM, and none of the 1,797 patients with ALL were found to have colorectal cancer. There were no operative mortalities, but 2 patients refused to have surgery. The ratio of observed to expected subsequent colorectal cancer in CLL was higher than it was in the other groups, indicating that the relative risk of colorectal cancer is higher in patients with CLL. CONCLUSION: Compared to the Surveillance, Epidemiology and End-Result (SEER) program at the National Cancer Institute (NCI) in the United State, we have the same high relatively risk in CLL patients. Careful attention should be paid to the possibility of colorectal cancer in CLL patients.

Solitary fibrous tumors (SFT) are rare spindle-cell neoplasms that are found principally in the pleura, and extrathoracic SFTs are even less common. We report here on a case of malignant solitary fibrous tumor in the perianal region. A 47-year-old man was referred to our hospital for surgical treatment of an incidentally discovered perianal mass. Pelvic MRI showed a slightly lobulated solid mass with central necrosis in the ischiorectal fossa. We performed complete removal of tumor with using a postanal approach. The resected specimen was 6.5x5.0x5.0 cm in size, and it was an elastic solid tumor with invasion to the surrounding muscle structures. Histologically, the tumor was composed of a patternless proliferation of spindle cells with a collagenous matrix and the tumor cells showed increased cellularity, cellular pleomorphism and frequent mitotic figure. Immunohistochemical staining was positive for CD34 and negative for desmin, which indicated malignant SFT. We report here on a rare case of malignant SFT in the perianal region along with a review of the literature.

BACKGROUND: 2.7% sorbitol-0.54% mannitol has been selected as an alternative irrigating fluid during endoscopic surgery for its theoretical advantages. We compared the influence of 2.7% sorbitol-0.54% mannitol (Urosol(TM), CJ Pharma, Seoul, Korea) and 5% glucose as an irrigating solution for hysteroscopic myomectomy & polypectomy in the occurrence of associated complications. METHODS: Thirty patients scheduled for a hysteroscopic operation were included in a prospective randomized trial comparing 2.7% sorbitol-0.54% mannitol solution (Group S, n = 15) and 5% glucose (Group G, n = 15) as an irrigating fluid. We recorded the amount of the irrigating fluids, the amount of fluid intake, and the duration of the procedure. Serum sodium, chloride, potassium, glucose values, and serum osmolality were measured before (just after the induction, T1), during (when 2 L of irrigation fluid was infused, T2), and after (1 h after the end of the operation, T3) the hysteroscopic procedure. RESULTS: The mean volume of absorbed irrigating fluid was 185.0 +/- 73.5 ml in Group G and 175.4 +/- 50.5 ml in Group S. Transient hyperglycemia occurred in one patient of Group G. No differences were found in the intraoperative and postoperative levels of serum sodium, potassium, chloride, glucose and osmolality in both groups. CONCLUSIONS: There was no clinical evidence of hyponatremic hypoosmolality in any of the patients. We found no difference between 2.7% sorbitol-0.54% mannitol and 5% glucose as an irrigating fluid for hysteroscopic procedures with mild to moderate irrigant absorption.
