A 7-year-old boy presented with hematochezia and abdominal pain. A 3.7-cm-sized mass was identified in the ascending colon by abdominal computed tomography and colonoscopy. The patient underwent surgical resection. Pathological examination revealed a low-grade perivascular epithelioid cell tumor (PEComa). PEComa in the colon is very rare. Only a few cases have been reported so far. An effective treatment method for this rare tumor has not been established yet. The patient received adjuvant interferon-${\alpha}$ immunotherapy for 1 year. He has been tumor-free for 26 months since the initial diagnosis. This report is the first documented case of the use of interferon-${\alpha}$ for pediatric PEComa of the colon.

A Maltese was presented with a subcutaneous mass at right flank, depression and hyperthermia. Ultrasonography revealed a hypoechoic mass with hyperechoic foci, a defect of abdominal wall and peritonitis. In cytology, fat necrosis was found. This dog was diagnosed as chronic suppurative steatitis secondary to pancreatitis and pancreatic herniation through surgery and histopathologic examination. Steatitis is recurrent inflammation and necrosis of adipose tissue. Also steatitis associated with pancreatic diseases such as pancreatitis and pancreatic tumor was reported and direct fat necrosis by pancreatic enzyme was supposed as the etiology. Steatitis secondary to pancreatitis was rarely reported in dogs and there was difficulty in diagnosis and treatment. This case has a limitation that pancreatitis was not diagnosed as underlying cause to steatitis before surgery. However, a defect of abdominal wall and peritonitis were observed on ultrasonography. Good prognosis could be achieved through prompt surgery and medical treatment.

Small bowel metastasis of pleomorphic carcinoma of the lung is very rare. A 58-year-old man was admitted to our hospital with abdominal palpable mass in the right upper quadrant area. He underwent right middle and lower lobectomy for early stage pleomorphic carcinoma of the lung approximately 3 months ago. USG-guided biopsy was performed for abdominal mass. Pathologic examination revealed a metastatic pleomorphic carcinoma from the lung. He received chemotherapy followed by radiation therapy but died due to septic shock caused by intestinal stenosis and adhesion. We report the first case of small bowel metastasis by pleomorphic carcinoma of the lung after curative surgery.

Human cysticercosis is an infestation with C. cellulosae, the larval stage of the tapeworm T. solium. It prevails in regions of poverty and where personal hygiene is poor. They can lodge in almost any tissue, but cysticerci are most frequently found in brain, skeletal muscle, subcutaneous tissues. We experienced a 41-year old male with $5{\times}12cm$ sized movable non tender brownish hard mass at lateral abdominal wall. The laboratory study didn't show any specific symptoms except peripheral blood eosinophilia and positive parasite ELISA screen for cysticercosis. The ultrasonogram revealed multiple ill-defined mixed echoic inflamatory lesion. Excisied cyst showed multiple severe foul-odor gelatinous subcutaneous mass. Microscopic examination disclosed necrotic body with foreign body reaction, massive eosinophilia and dead parasitic organism, compatible with cysticercosis. There was no evidence of recurrence during 12 months follow-up.

Objectives : The objective of this study is to assess the prevalence and risk factors of metabolic syndrome (MS) among inpatients with schizophrenia, and to compare with general population. Methods : Nine hundreds seventy inpatients were included to assess the prevalence of MS from two mental hospitals in Yong-in city. Assessment of MS was performed based on modified American Heart Association criteria with abdominal obesity threshold of 90cm for men, 85cm for women. Comparative analysis was performed using age- and gender matched sample from Korea Health and Nutritional Examination Survey III. For evaluating risk factors, analysis included 766 inpatients taking consistent medications at least for 30 days. Results : The prevalence of MS of inpatients with schizophrenia was 26.2%, in females it was 33.2%, compared to 20.2% in males(p < 0.001). Compared to general population, the prevalence of MS was significantly lower in male and higher in female patients. In terms of criteria prevalence, who met abdominal circumference criterion were more prevalent in patient group(p < 0.001). After multivariate analysis, female gender and old age remained as risk factors of MS. Conclusions : The prevalence of MS of inpatients with schizophrenia was 26.2% and significantly low compared to general population. Female gender and old age were risk factors of MS.

Midaortic syndrome (MAS) is a rare vascular disease that commonly causes renovascular hypertension. The lumen of the abdominal aorta narrows and the ostia of the branches show stenosis. MAS is associated with diminished pulses in the lower extremities compared with the upper extremities, severe hypertension with higher blood pressure in the upper rather than lower extremities, and an abdominal bruit. The clinical symptoms are variable, and recognition in children with hypertension can aid early diagnosis and optimal treatment. Hypertension with MAS is malignant and often refractory to several antihypertensive drugs. Recently, radiologic modalities have been developed and have led to numerous interventional procedures. We describe the case of a 3-year-old boy presenting with left ventricular hypertrophy whose severely elevated blood pressure led to the diagnosis of idiopathic MAS. This case highlights the importance of measuring blood pressure and conducting a detailed physical examination to diagnose MAS. This is the first reported case of idiopathic MAS diagnosed in childhood in Korea.

Twelfth rib syndrome is thought to be due to intercostal nerve irritation by a mobile twelfth rib, and presents with upper abdominal pain, or low thoracic pain. This syndrome appears to be a fairly common entity and diagnosis is based on clinical findings. Patients with twelfth rib syndrome can be misdiagnosed when it has been overlooked. We report a case of a 34-year-old male along with a presentation of twelfth rib syndrome. One patient was transferred from urologic clinic to pain clinic due to right flank pain and admitted. The patient had direct tenderness on twelfth rib area and direct tenderness was reproducible. Pain increased when the patient flexed laterally, rotated trunk. There were no specific abnormal findings in laboratory test, electrocardiogram, and radiologic examination. After intercostal nerve block and epidural block, pain decreased and the patient was discharged.

Four dogs (case 1; 2-year-old spayed female Schnauzer, case 2; 3-year-old spayed female Cocker Spaniel, case 3; 9-year-old castrated male Yorkshire Terrier, and case 4; 9-year-old intact female Shih-tzu) were referred to us with gastrointestinal signs such as diarrhea, vomiting, and anorexia. Results of blood analysis revealed hypoproteinemia and hypoalbuminemia in all dogs. Case 4 showed large circular mass which is connected with small intestine on abdominal ultrasonography and other 3 cases showed no remarkable findings on abdominal radiography and ultrasonography. We performed enterectomy in case 4 and gastrointestinal endoscopic examination with biopsy in other 3 patients. Finally, 4 patients diagnosed to protein losing enteropathy with 4 different etiologies.

Pancreatoblastoma is uncommon in children and is exceedingly rare in adults. Prognosis is good if the tumor is removed prior to metastasis. Complete tumor resection is the most important factor for long survival. We report two cases of pancreatoblastoma in 4 and 7 years old girls. Palpable abdominal mass was accidentally found by their parents. Abdominal CT scan showed a huge retroperitoneal mass of unknown origin in one case and a mass involving the pancreas in the other case. At laparotomy, well encapsulated tumor mass($10{\times}10$ cm in maximum dimension) was noted in the body of pancreas in one case, and in the tail of pancreas in the other case( $8{\times}7$ cm). We resected the tumor and preserved the spleen in both cases. Histological examination revealed that the tumors were pancreatoblastoma. Patients received postoperative chemotherapy with 6 cycles of cisplatinum, adriamycin, ifosfamide and etoposide and are alive in good condition 19 months and 17 months after operation.

A 13-year old female miniature Poodle was presented with ventro-abdominal skin purpura. All mammary glands were included, but right side mammary glands and left thoracic gland were mild while left abdominal and inguinal glands were moderately changed. Overlying skin of mammary glands was purple colored, thickened, and firm. Yellowish brown colored mammary discharge was noticed from every teats except cranial thoracic gland. On histologic finding, dermal lymphatic vessels were filled with tumor emboli that stained positively with cytokeratin. This case was diagnosed as inflammatory mammary carcinoma by clinical examination and histopathologic finding.
