A large mass as a sign of an infection is rare, and it might convince a physician that it had the appearance of a malignancy. The patient in this case visited our clinics after attending several hospitals, with a mass that had the appearance of a malignancy, based on the severe destructive findings observed on plain radiographs. We report the first documented case of a patient with a large mass (12×7×20 cm) and a low-grade infection, which developed at the proximal thigh after a hip arthroplasty. It is important to realize that an infection accompanied by a large mass, can mimic a highly destructive malignant lesion on plain radiographs.

Acute osteomyelitis is usually shown as a localized area of increased activity (hot uptake) in the infectious focus on bone scintigraphy. In our patient, absence of radioactivity (cold lesion) was noted in the distal metaphyseal and diaphyseal regions of his right femur. Initial x-ray was interpreted as normal except for mild soft tissue swelling in the right thigh. The lesion was confirmed as an acute osteomyelitis with subperiosteal abscess on surgery. Staphylococcus aureus was the etiologic organism. We describe a case of acute osteomyelitis in a one-year-old boy shown as a cold lesion on bone scan.

Displaced acetabular fractures have given rise to difficulty to the management, It has been unique diagnostic and operative challanges for the surgeon. We made a retrospective study of hip arthroplasty in fourteen patients who had a history of previous acetabular fracture. The most of patients was sutfered from traumatic osteoarthritis, We performed two bipolar hemiarthroplasty, eleven non-cement cup and one case Charnley cup replacement were done. The purpose of this stady was to determine the outcome long-term cup. The clinical results showed that pain was most improved at foliow-up, but the incidence of radiographic loosening and revisions were higher 42.8% within 10 years. We conclude that a history of prior acetahular fracture has a significant adverse impact on the long term out come of acetabular cup in total hip arthroplasty.

The ischemic coitis proximal to obstructive colon cancer was firstly reported by MacCallum and Kaisch in 1947. Nowsdays, its clinical importance and the study of pathogenesis is reported frequently. Because of the rare inciedence of this complicated condition this lesion could be overlooked which then could result anastomotic leakage, fecal fistula and peritonitis. Recently, we have examined a 61 year-old Korean male patient who had the complaints of acute abdominal pain and bloody diarrhea. The diagnosis of gangrenous ischemic colitis associated with obstucting rectal cancer was confirmed on the basis of sigmoidoscopic and operative and associated histopathological findings. After prompt surgical intervention, the patient was discharged with good improvement. The literatures are reviewed here with the case presentation.

BACKGROUND: The stomach is the most common extra nodal site for non-Hodgkin's lymphoma: primary gastric lymphomas are uncommon, constituting only 1% to 5% of malignant gastric lesions. METHODS: To elucidate the clinicopathologic features of this lymphoma, we retrospectively analyzed 33 patients with primary gastric lymphoma who had been treated at our hospital from Jan. 1986 to Dec. 1995. RESULTS: Primary gastric lymphomas were 1.2% of all gastric cancers. The mean age 46 years (range 25 to 68 years). There were 23 men and 10 women. The most frequent chief complaint was epigastric pain. The most common location was the gastric antrum and body. According to the working formulation, the malignancy grades were 4 low, 26 intermediate, and 3 high. The overall 5-year survival rate was 60%. Survival of five years according to the TNM stage of the disease was as follows: stage 1, 88%; stage II, 71%; stage III, 33%; and stage IV, 29%. Patient with stage I, II disease had a 5-survival rate of 80% versus 35% for stage III, IV disease (p<0.05). Tumor serosal involvement and 5-year survival was follows: no perigastric serosal involvement, 93%; serosal infiltration, 33% (p=0.0016). In cases undergoing a subtotal gastrectomy, 5-year survival rate was 70%, whereas patients undergoing a total gastrectomy had a 5-year survival rate of 30% (p<0.05). Those with tumors smaller than 7 centimeters had a 5-year survival rate of 66% versus 38% for larger neoplasms (p=0.09). CONCLUSIONS: By univariate analysis, the stage, operation methods, and serosa involvement were significant prognostic factors. However, in multivariate analysis, only the serosa involvement was significant prognostic factor.
