Maligant melanomas of the oral or nasal cavity, and the vulvovaginal area are relatively common among the melanomas of non-ocular mucosa. But, primary malignant melanoma arising in the mucosa of the palatine tonsil is rare. We present a case of primary malignant melanoma arising in the mucosa of the palatine tonsil. A 36-year-old male was admitted for evaluation of a recurrent sore throat. Tonsillectomy was performed on the basis of clinical suspicion of chronic tonsillitis. Grossly, the left tonsil was focally dark. Microscopically, the tonsillar mucosa was diffusely infiltrated with tumor cells. Tumor cells revealed numerous melanin pigments. Intraepithelial nests of tumor cells were noted, but pagetoid spread of tumor cells was not found. Tumor cells were positive for S-100 protein and HMB45 stain. There was no evidence of melanoma in the skin or eye.

PURPOSE: To investigate the clinical effects of a single high dose intravenous immunoglobulin (IVIG) combined with initial dexamethasone as a primary treatment on Kawasaki disease (KD). MATERIALS AND METHODS: Between January 2008 and December 2010, we reviewed the medical records of 216 patients with complete KD patients that were admitted to a single medical center. 106 patients were treated with a single high dose of IVIG (2 g/kg) alone and 110 patients received IVIG and dexamethasone (0.3 mg/kg per day for three days). RESULTS: The combined IVIG plus dexamethasone patient group had a significantly shorter febrile period and duration of hospital stay (1.4+/-0.7 days vs. 2.0+/-1.2 days, p<0.001; 5.8+/-1.7 days vs. 6.9+/-2.5 days, p<0.001, respectively) than the IVIG alone group. The combined IVIG plus dexamethasone group required IVIG retreatment significantly less than the IVIG only group (12.7% vs. 32%, p=0.003). After completion of the initial IVIG, C-reactive protein levels in the combined IVIG plus dexamethasone group were significantly lower than those in the IVIG only group (2.7+/-4.0 mg/dL vs. 4.6+/-8.7 mg/dL, p=0.03). In the combined IVIG plus dexamethasone group, the incidence of coronary artery lesions tended to be lower without worse outcomes at admission after initial infusion of IVIG and in follow-up at two months; however, the differences were not significant (8.2% vs. 11.3%, p=0.22; 0.9% vs. 2.8%, p=0.29). CONCLUSION: Initial combined therapy with dexamethasone and a single high-dose of IVIG resulted in an improved clinical course, in particular a shorter febrile period, less IVIG retreatment, and shorter hospital stay without worse coronary outcomes.

OBJECTIVES: The purpose of this study was to evaluate the anti-cancer activity of cisplatin by studying its effects on cell viability and identifying the mechanisms underlying the induction of cell cycle arrest and apoptosis on oral squamous cell carcinoma (OSCC) cell lines with varying p53 mutation status. MATERIALS AND METHODS: Three OSCC cell lines, YD-8 (p53 point mutation), YD-9 (p53 wild type), and YD-38 (p53 deletion) were used. To determine the cytotoxic effect of cisplatin, MTS assay was performed. The cell cycle alteration and apoptosis were analyzed using flow cytometry. Western blot analysis was used to detect the expression of cell cycle alteration- or apoptosis-related proteins as well as p53. RESULTS: Cisplatin showed a time- and dose-dependent anti-proliferative effect in all cell lines. Cisplatin induced G2/M cell accumulation in the three cell lines after treatment with 0.5 and 1.0 µg/mL of cisplatin for 48 hours. The proportion of annexin V-FITC-stained cells increased following treatment with cisplatin. The apoptotic proportion was lower in the YD-38 cell line than in the YD-9 or YD-8 cell lines. Also, immunoblotting analysis indicated that p53 and p21 were detected only in YD-8 and YD-9 cell lines after cisplatin treatment. CONCLUSION: In this study, cisplatin showed anti-cancer effects via G2/M phase arrest and apoptosis, with some difference among OSCC cell lines. The mutation status of p53 might have influenced the difference observed among cell lines. Further studies on p53 mutation status are needed to understand the biological behavior and characteristics of OSCCs and to establish appropriate treatment.

BACKGROUND: The use of ambulatory blood pressure monitoring (ABPM) in childhood hypertension has been in great advance. ABPM has been able to detect significantly high blood pressure (BP) and also helpful for identifying white coat hypertension. METHODS: Between March 2007 and December 2009, we evaluated individuals aged from 7 to 19 years who were referred as high BP with ABPM, echocardiogram, and abdominal computerized tomography, calculation of body mass index (BMI) at Ajou University Hospital. ABPM was performed using the Tonoport V monitors and SpaceLab 90217 monitors. Seventy were evaluated with 55 boys and 5 girls. The mean age of them was 13.1 +/- 2.8 years (mean +/- standard deviation). RESULTS: Forty of seventy (57.1%) were diagnosed as hypertension in ABPM and 8 of 40 were diagnosed as secondary hypertension with underline diseases such as hyperthyroidism, chronic renal disease, Takayasu's arteritis, coarctation of aorta. The mean BMI in 40 was 24.8 +/- 4.72 kg/m2. Twenty-three of seventy (32.8%) were obese with higher prevalence than in general population. White coat hypertension was diagnosed in 30 of 70 (42.9%). CONCLUSIONS: ABPM could provide more detailed data including mean values of BP, load, and night dip in assessment of children's BP. According to increasing children's obesity, use of ABPM was thought to be necessary for evaluation of their risk of hypertension and useful for diagnosis of masked hypertension and white coat hypertension. Further more study of ABPM in children and adolescents would be needed for absolute standards of ABPM.

Skin has long been known to be a very radiosensitive organ. Furthermore, the damaging effects of radiation exposure induced by fluoroscopic procedures have been recognized for some time. However, accurate diagnosis of fluoroscopy-induced chronic radiation dermatitis (FICRD) can be very challenging, since the provided clinical history regarding radiation exposure may not be accurate and the signs of cutaneous radiation injury may develop months to years after radiation exposure. Recognition of FICRD is important to avoid unnecessary treatment and interventions and also guarantees appropriate surveillance for radiation-induced malignancy. We herein report a case of a 65-year-old woman who was diagnosed with radiation dermatitis after endoscopic retrograde cholangiopancreatoscopy (ERCP).

Fine needle aspiration cytology (FNAC) is an easy convenient non-invasive method in the diagnosis of superficial palpable masses. The cytologic findings by FNAC of reactive and neoplastic lesions in various organs including breast, lymph node, thyroid, salivary gland, etc., have been described, but, those of soft tissue lesions including proliferative fasciitis are relatively rare to find. We recently experienced a case of FNAC of proliferative fasciitis in the left back of a 72-year-old male. The FNAC smears were scant in cellularity and contained large cells with abundant basophilic cytoplasm, one to two nuclei lying at the periphery, and prominent nucleoli that resemble ganglion cells.
