The pilomatricoma (Calcifying Epithelioma of Malherbe) is rare benign tumor of adnexal keratinocytes. It is occuring usually as a single, asymptomatic, 0. 5 cm to 3. 0 cm sized, deep seated, firm nodule, covered by normal or pink skin. Multiple pilomatricoma is relatively rare, as 3. 5% of reported cases of pilomatricoma. A 21-year-old male patient had 7 subcutaneous nodules on the neck, both upper extremities and trunk for 9 years. We excised one of them, under the impression of calcinosis cutis, cysticercosis cutis or benign skin tumor. But histopathologic findings of the lesion showed the typical pattern of pilomatricoma with shadow cells, calcification and foreign body giant cells. Five of remainders were excised and they showed same histopathological findings of pilomatricoma. The authors presented herein one case of multiple pilomatricoma with the review of literature.

소아 급성 신우신염에서 출력 도플러 초음파검사

이승주,이선화,Lee Seung-Joo,Lee Sun-Wha 대한소아신장학회 2002 Childhood kidney diseases Vol.6 No.2

목적: 소아의 급성 신우신염에서 신실질병소의 발견에 대한 출력도플러초음파의 진단적 유용성을 평가하고자하였다. 대상 및 방법: 임상적으로 상부요로감염으로 진단된 80명의 소아에서 회색도초음파, 출력도플러초음파 및 $^{Tc-99m}DMSA$ 신티그라피를 시행하였고 각 검사간의 시간 간격은 4일 이내였다. 급성 신우신염의 신실질병소에 대한 진단 기준은 신티그라피에 관찰되는 방사능축적이 감소되거나 결손된 부위였고, 출력도플러초음파에서는 삼각형의 신장내 관류가 저하되거나 없는 부위였다. 급성 신우신염에 대한 객관적인 참조기준은 신티그라피 소견이었고 이를 출력도플러초음파와 회색도초음파 결과와 비교분석하였다. 결과: 신티그라피에서 급성 신우신염의 병소가 발견된 47명중 40명(85%)은 출력도플러초음파에서도 관류의 이상이 관찰되는 양성소견을 보였다. 출력도플러 초음파 소견이 위음성인 경우가 7명, 위양성인 경우가 3명 있었다. 회색도초음파경우 신티그라피에서 병소가 발견된 47명중 23명(49%)에서 이상소견을 관찰할 수 있었다. 결론: 출력도플러초음파는 소아의 급성 신우신염의 진단에 있어 신티그라피보다는 민감하지 않으나 회색도초음파에 비해서는 매우 민감하였다. 출력도플러 초음파는 급성 신우신염을 의심하는 소아에서 신장으로의 관류이상을 평가할 수 있는 비침해적인 검사로 진단적 가치가 있다. Purpose: The purpose of this study is to assess the ability of power Doppler sonography in the detection of acute pyelonephritis. Materials and Methods: We performed gray scale sonography, power Doppler sonography, and $^{Tc-99m}DMSA$ scintigraphy of the kidney in 80 patients with symptoms suggesting upper urinary tract infection. All imaging studies were obtained within 4 days. On $^{Tc-99m}DMSA$ scintigraphy, decreased radioactivity or photopenic lesions were considered indicative of acute pyelonephritis. Triangular areas of decreased perfusion identified on power Doppler sonography were considered as parenchymal lesions of acute pyelonephritis. The results of gray scale sonography and power Doppler sonography were retrospectively analysed and compared with those of $^{Tc-99m}DMSA$ scintigraphy which was given as the standards of reference. Results: For 40(85%) of the 47 patients with scintigraphy-proven acute pyelonephritis, power Doppler sonography diagnosed this condition on the correct side. The acute pyelonephritis which was not revealed by power Doppler sonography was observed in seven patients. Also, in three patients, false-positive indication of pyelonephritis was given by power Doppler sonography. Gray scale sonography showed positive findings in 23(49%) of 47 patients with positive findings on scintigraphy. Conclusion: Power Doppler sonography seems to be less sensitive than $^{Tc-99m}DMSA$ DMSA scintigraphy but significantly more sensitive than gray scale sonography for the detection of acute pyelonephritis in children. Power Doppler sonography shows promise as a noninvasive means of assessing renal cortical perfusion in children with clinically suspected acute pyelonephritis.

Secondary osteoarthritis of the hip jjoints is a common disease and is frequently followed by chronic sublexation and dislocation. Twenty four cases of the secondary osteoarthritis associated with chronic subluxation and dislocation of the hip joints were evaluated with plain radiography and computed tomotraphy. We retrospectively analyzed 1) the ossification and calcification of the acetabular labrum, 2) the thickeness of the quadrilateral plate of the ilium, and 3) anteroposterior diameter of the acetabulum. The changes of the hip joints in subluxation (n=14) revealed ossification of the acetabular labrum in 12 cases (86%), thickening of the quadriateral plate of the ilium in 11 cases (78%) but anteroposterior diameter of the acetabulum was not changed The changes of the hip joints in dislocation (n=10) revealed no evidence of the ossification of the acetabular labrum, thickening of the quadrilateral plate of the ilium in 10 cases (100%) and decreased anteroposterior diameter of the acetabulum. We conclude that CT findings of subluxation and dislocation of the hip joints can be helpful in the evaluation of the secondary osteoarthritis of the hip joints.

저자들은 지속되는 고열과 복통을 주소로 입원한 10세 남아에서 외과적인 복부 질환이 의심되어 시험적 개복술을 시행하여 복막 조직 검사 소견과 복수에서 결핵균의 배양으로 확진하고 항결핵제 투여로 치료한 결핵성 복막염 1례를 문헌고찰과 함께 보고하는 바이다. Childhood tuberculous peritonitis is difficult to diagnose especially in cases without pulmonary involvement. It may present as mechanical ileus, perforation, simulating acute appendicitis, enterocolitis or intusussception. Early diagnosis in children may be difficult, largely because of variable vague symptoms and nonspecific signs. Surgery has often been required for pathologic confirmation. We have experienced a case of tuberculous peritonitis presenting with abdominal pain, abdominal distension and persistent high fever in a 10-year-old boy who was diagnosed by explo-laparotomy and pathologic confirmation from biopsy specimen from omentum. The patient was treated with antituberculous drugs and recovered uneventfully.

전신 홍반 루푸스는 다양한 증상으로 발현되는 자가면역질환이다. 위장관 증상도 질환의 경과 중에 나타날 수 있으나, 장 가성 폐쇄로 처음 진단되는 경우는 소아에서 매우 드물다. 장 가성 폐쇄는 원발성 또는 속발성으로 장의 평활근이나 신경계에 이상이 있어 해부학적 원인 없이 장폐쇄의 증상과 징후가 나타나는 것이며, 장폐쇄로 인하여 수술을 하였다는 보고도 있다. 그러나 장 가성 폐쇄가 전신 홍반 루푸스에 속발한 경우 장간막 혈관의 폐쇄와 장괴사로 진행하기 전에 조기에 진단하고 치료하면 합병증을 예방하고 수술을 피할 수 있다. 저자들은 장 가성 폐쇄의 증상으로 내원한 13세 여아에서 전신 홍반 루푸스를 진단하여, 불필요한 수술을 피하고 조기에 치료한 증례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Intestinal pseudo-obstruction (IPO) is a rare and poorly understood manifestation of systemic lupus erythematosus (SLE), especially in children. The characteristic clinical feature of IPO is obstruction without an identifiable obstructive lesion. The authors a 13-year-old girl whose first symptom of SLE was IPO. The patient presented with a 3-day history of nausea, bilious vomiting, abdominal distention, and no bowel movement. Simple abdominal radiographs revealed mild dilatation with partial air-fluid levels in the small intestine. Abdominal CT and methylcellulose small bowel studies showed massive ascites, engorgement of the small mesenteric vessels, pleural effusion, and diffuse bowel wall thickening of the gastric antrum, duodenum. and jejunum. The delayed passage of contrast for 15 days after the methylcellulose small bowel studies was suggestive of decreased bowel motility. Laboratory findings were positive for ANA, anti-double-stranded DNA, anti-Smith and lymphopenia. After 10-day treatment with high-dose corticosteroids, the symptoms improved. IPO associated with SLE should be considered in the differential diagnosis for patients presenting with symptoms of intestinal obstruction. Early recognition of IPO in SLE and appropriate therapy are important for prevention of complications and unnecessary surgery. This case raises awareness among pediatricians that although rare, IPO can be the presenting symptom of SLE in children.

The computed tomographic findings of cerebral arterial ectasia in 8 patients, of which 5 cases were angiographically documented, are reported. The ectatic arteries, located predominantly in the suprasellar and interpeduncular cisterns, appeared as serpiginous, tubular structures on the unenhanced scan. The enhanced CT scan demonstrated dense, sharply defined, homogeneous intraluminal enhancement. Until recently, the diagnosis of cerebral arterial ectasia was usually established by angiography. With introduction of CT it has become possible to noninvasively indentify and characterize this vascular disorder and its associated intracranial complications. The vertebrobasilar dolichoectasia may be diagnosed by CT as an extra-axial lesioin in the cerebellopontione angle. It enhances in a tubular fashion after intravenous injection of contrast.
