We report a case of tuberculosis verrucosa cutis in a 33-year-old male patient who presented with mild itching verrucous plaque over the perineum. The Mantoux test revealed a positive reaction. The histophathologic picture consists of slight hyperkeratosis, irregular ac:anthosis overlying an inflammatory iafitrate in the dermis. Tuberculous granulomas with caseation necrosis were seen in the dermis. Tuber clebacillus was demonstrated. The patient was treated with Isoniazid, Rifampicin, and Pyrazine made for 6 months. To date, the skin lesions have markedly improved.

Kasabach- Merritt syndrame consists of thrombocytopenia, microangiopathic hemolytic anemia, and an acute or chronic censumptive coagulopathy in associati an with a rapidly enlarging hemangioma. Most vascular turrnrs causing Kasabach-Merritt syndon e are benign but the associated coagulopathy may be lifethreatening. Our patient, a 30-day-old female infant, was admitted after an increase in the size of a hemangioma present since birth on the right leg with extension to the lower abdomen and left inguinal area. Her herrnglobin count fell to 7.1g/dl, platelet count was 26,000/ul, prothrombin time was 26 seconds, and hypofibrinogenemia developed. The patient was treated with transfusions of platelets, fresh frozen plasma and red cells and prednisolone. for 2 weeks without improvement. We started interferon alfa-2a therapy. Over the past 6 months, he hemangioma progressively diminished in size withcut any serious complication.

BACKGROUND: Several studies have demonstrated that quantitation of hepatitis B virus (HBV) DNA in sera of HBsAg-positive patients is more useful test for the assessment of infectivity and for the evaluation of disease status than previously utilized numerous serological markers and qualitative polymerase chain reaction for the detection of HBV DNA. We tried to measure serum HBV DNA using a branched DNA (bDNA) signal amplification assay, which is recently introduced and known to be a simple and nonradioisotopic method. METHODS: Total forty patients with HBsAg were randomly selected and serum HBV DNA was measured with duplication using bDNA signal amplification assay (QUANTIPLEXTM HBV DNA ASSAY, Chiron, USA). Quantitation was determined from a standard curve and expressed as HBV DNA equivalents/mL (Eq/mL; 1 Eq = 1 molecule of the primary HBV DNA standard). Serum HBeAg, aspartate aminotransferase (AST), alanine aminotransferase (ALT) , and soluble interleukin-2 receptor (sIL-2R) were compared with HBV DNA. RESULTS: Serum HBV DNA was quantitated in 13 patients (32.5%) (range 6.4x106-7.4x109 Eq/mL, mean 1.8x109 Eq/mL, CV 8.1%). All eleven patients (100%) with both HBsAg and HBeAg an4 2 of 29 patients (6.9%) with HBsAg but not with HBeAg showed measurable HBV DNA (p < 0.001). In addition, serum levels of AST, ALT, and sIL-2R were significantly higher in HBV DNA measured patients compared with those of unmeasured patients. CONCLUSIONS: Above results show that more than half the HBsAg-positive patients do not have enough HBV DNA which is measurable with boNA signal amplification assay but all of HBeAg-positive patients and some of HBeAg-negative patients do. In addition, HBV DNA quantitation might be correlated with the disease activity in HBsAg-positive patients because serum levels of AST, ALT, and sIL-2R are higher in patients measured with HBV DNA than unmeasured.

The authors experienced a case of gastroduodenojejunal trichobezoar detected by ultrasongraphic examination. We thought that tricholbezoar had relatively specific ultrasonographic findings such as a broad hyperechogenic superficial bandlike rim with a complete posteior sonic shadowing and multiple linear echogenic strands on its surface representing hairs, which were better seen after water ingestion. So we were able to get the correct diagnosis of trichobezoar prior to conventional barium studies in a patient who could not be suspected suspected clinically.

PURPOSE: The purpose of this study was to compare mammography and breast sonography in detection of breast cancer and to suggest reasonable guideline of breast imaging in breast cancer patients under 30 years of age in whom breast cancer shows different clinicopathologic characteristics compared with breast cancer in older women. MATERIALS AND METHODS: A. uthors reviewed medical records of 27 patients under 30 years of age with pathologically-proven breast cancer. Age, family history, physical examination findings, indications for breast s0nography were reviewed. Cases in whom breast cancer lesion is detectable and cases in whom not detectable using mammography or breast sonography were reviewed. And then, authors evaluated the usefulness of each method and reasons for nonvisualization of lesion on mammography. RESULTS: Among 27 patients, 25 patients had palpable breast mass as indication of mammography and breast sonography. Cancer lesions were detectable in 16 of 25 patients (64%) on mammography and 24 of 25 patients (96%) on breast ultrasonography. Reasons for nonvisualization of cancer lesions on mammography were dense breast with nodular parenchyma pattern and minimal breast change of ductal carcinoma in situ. CONCLUSION: In breast cancer patients under 30 years of age who have palpable breast mass as a initiaJ, and main clinical problem, breast ultrasonography is superior to mammography in detecting and diagnosing breast cancer. We suggest that guidelines can avoid unnecessary mammography in these patients.
