Spindle cell hemangioendothelioma was first described in 1986 by Weiss and Enzinger as a low grade angiosarcoma resr mbling a cavernous hemangioma and kaposis sarcoma. Recently, it is suggested to be non neoplastic lesion or reactive process arising from pre-existing vascular mal- formation. We report a case of spindle cell hemangioendothelioma in a 9-month-old boy. He had multiple, variable sized, colorful, cutaneous or subcutaneous nodules on the forearm and hand. The tumor first appeared on the forearm as erythematous patches at birth and grew rapidly with- in 3 months. Histopatholgical findings showed that the lesion was composed of thin walled cavernous spaces mixed with spindle cells and occasional epithelioid endothelial cells containing intracytoplasmic vacuole. Most af the endothelial cells lining the cavernous spaces and intracytoplasmic lumina, were positive for factor VIII associated antigen. But the spindle cells were negative. Atypical vascular structures resembling arteriovenous shunts were noted around the tumor suggesting a reactive proliferation due to disturbance of local blood flow. Several turnors were excised. No recurrence has been recognized in the one year- follow-up period.

BACKGROUND: Plaque compression (and/or redistribution) and vessel expansion are important mechanisms of percutaneous coroanry balloon angioplasty. We investigated the mechanisms of balloon angioplasty according to plaque characteristics by intravascular ultrasound and assessed the time-sequencing morphometric changes of target vessel after balloon dilation without catheter change using intravascular ultrasound balloon catheter. METHOD: We studied balloon angioplasty in 10 patients (eight male, average age of 55.3 years). Quantitative coronary angiography and intravascular ultrasound images were attained at baseline and at timed intervals of 0sec, 60sec and 180sec post-balloon angioplasty. The following categories were attained : reference diameter, minimal lumen diameter, cross sectional area (CSA) of lumen (L), external elastic membrane (EEM), and plaque + media (P+M). We also assessed the plaque morphology of target lesion and classified them into two groups according to intravascular ultrasound imaging : a soft plaque group versus a group characterized by fibrous and/or mildly calcified plaque. RESULTS: The proportions of plaque compression in the total luminal gain were 80% in the soft plaque group and 70% in the other ; the absolute amount of plaque compression was 26.9% in soft plaque and 24.0% in the other group. The time sequencing changes of target lesion EEM CSA of both group were 14.4+/-2.9mm2, 14.3+/-3.8mm2 (baseline) 15.1+/-2.5mm2, 15.4+/-3.7mm2 (immediate) 15.0+/-2.8mm2, 14.5+/-3.9mm2 (180sec), those of P+M CSA (target lesion) were 10.4+/-3.3mm2, 10.7+/-2.4mm2 (baseline) 7.6+/-2.7mm2, 8.1+/-2.4mm2 (immediate) 7.9+/-2.9mm2, 8.5+/-3.4mm2 (180sec). Target lesion lumen CSA were 4.0+/-1.1mm2, 3.6+/-2.0mm2 (baseline) 7.5+/-1.1mm2, 7.3+/-3.2mm2 (immediate) 7.1+/-1.3mm2, 6.0+/-1.7mm2 (180sec) respectively. CONCLUSION: Plaque compression (and/or redistribution) is the predominant mechanism of luminal gain in both groups. The absolute amounts of P+M CSA changes and time sequencing increment of target lesion were similar in both groups. In the non-soft group, the immediate increment and time sequencing reduction of EEM CSA in target lesion were greater than those of the soft plaque group.

BACKGROUND: Women sometimes have eyebrows tattooed for cosmetic purpose. But until recently, the removal of tattoos has been difficult. Several laser techniques have been proposed for the removal of tattoos. The lasers that have been used most successfully are the Q-switched systems because of their ability to target tattoo pigment selectively with minimal risk of adverse tissue response. OBJECTIVE: The objective of this study was to determine the clinical effectiveness of the newest Q-switched system, the alexandrite laser, in removing both eyebrow tattoos and to observe side effects such as scarring or permanent pigmentary changes. METHODS: Forty seven patients with both eyebrows tattooed were treated with the Q-switched alexandrite laser (755 nm, 100 ns) at eight week intervals and clinically evaluated.

BACKGROUND: This study was designed to investigate the relationship between psychiatric disease and systemic Internal Medical disease in psychiatric inpatients who were consulted to department of Internal Medicine and was directed to assess the physical problems and possible ways to resolve them in a closed psychiatric unit. METHOD: Through evaluation of medical records of 1549 inpatients who had consulted in department of internal medicine in Seoul National(mental) Hospital from January 1, 2002 to December 31, 2002. We classified the Physical illness according to ICD-9-CM and psychiatric disease according to DSM-IV RESULTS: The results were as follows: 1) In age and sex distribution, male was 64.4% and 45.9% of the subject was 4th and 5th decades. 2) The most systemic diagnosis were disease of respiratory system, disease of digestive system and endocrine system. 3) schizophrenia showed the highest rate in respiratory disease. Rate of digestive disease was the highest in alcohol use disorder. Disease of respiratory system and disease of digestive system were the most frequent in mood disorder 4) In 1st decade, Digestive system digease was the most frequent, others were respiratory system disease. 5) onset age of psychiatric disease was the oldest in circulatory disease. In genitourinary system disease, duration of psychiatric disease was the longest CONCLUSION: The clinical characteristics of psychiatric disease influenced to get systemic disease in psychiatric patients.
