Duodenal gastrointestinal stromal tumors (GISTs) are uncommon and a relatively small subset of GISTs whose optimal surgical procedure has not been well defined. Because submucosal spread and local lymph node involvement is infrequent in GISTs, wide margins with routine lymph node dissection may not be required. Various techniques of limited resection for duodenal GISTs have been described depending on the site and the size of the tumors. In this study, we report two cases of GIST involving the third and fourth portion of the duodenum successfully treated by segmental duodenectomy with end-to-end duodenojejunostomy. This technique should be considered as a treatment option for GIST located at the third and fourth portion of the duodenum.

PURPOSE: lntra-arterial cisplatin infusion chemotherapy delivers higher concentration of this therapeutic agent to the limited area of cervical carcinoma. We evaluated the role of endorectal ultrasonography (ERUS) in the analysis of the tumor response to this chemotherapy. MATERIALS AND METHODS: ERUS was done in 20 patients of cervical carcinomas limited to the pelvis by rotating the 5 UHz linear arraytransducer along the reference sagittal plane in the middle of uterine cervix and vagina. We examined and compared the change of tumor size and morphology on ER US, before, during and after intra-arterial cisplatin (50 mg/m2) chemotherapy through internal lilac artery near uterine arterial branching. Colposcopy and radical hysterectomy with pelvic lymphadenectomy were performed in all patients, and ERUS findingswere compared with those findings. RESULTS: ERUS correlated well with surgery in the estimation of preoperative tumor size and morphology. Tumor reduction rate on ERUS (100-the largest area of the preoperative tumor/the largest area of the initial tumor) was as follows: more than 75% decrease of the original size in 3 patients, 75% -50% in 6 patients, 50%-25% in 8 patients, and less than 25% in 3 patients. Hyperechoic reflecting areas were noted in 4 patients, which corresponded to gaseous necrosis on postoperative pathology. CONCLUSION: ERUS is helpful to evaluate the morphologic change of cervical carcinoma limited tothe pelvis in intra-arterial cisplatin chemotherapy.

A 62-year-old man presented with a tender, solitary nodule on the left upper arm. He had no specific family history of the lesion. A biopsy specimen showed various sized irregular vascular lumens in the upper dermis. The vascular walls consisted of an endothelial cell layer and rim of one to three layers of glomus cell nests outside the endothelial cells. The cell nests consisted of round shaped epitheloid cells with relatively uniform round or oval shaped nuclei and pale cytoplasm. These tumor cells were strongly positive for vimentin, and a-smooth muscle actin. On electron microscopic examination, the cytoplasm of these tumor cells contained fine filamentous components and many electron dense bodies were found at the plasma membrane and the cytoplasm. We report a case of a solitary glomus tumor(glomangioma) that showed the histological features of the multiple type of glomus tumor. In addition we describe the results of an immunohistochemical and electron microscopic study.

The subluxation of the femoral head is one of important prognostic factors in LCPD and current treatment of LCPD is based on the premise that adequate containment of the vulnerable femoral head within the acetabulum during the process of repair should result in a more spherical femoral head and a more congruous joint than if treatments were not provided.We analised the arthrographic findings of 18 hips in unilateral LCPD in order to determine the changes of the femoral head and acetabulum, degree of the subluxation and containment of the femoral head in various position of hip. The results were as follows: 1. According to the result of sphericity, the femoral head was deformed mainly in coronal plane in LCPD. 2. Average medial joint space of normal hip was about 3.8mm in the AP view of hip, but it was more increased in any position of LCPD. 3. In abduction with internal rotation, average subluxation ratio was 7.5% in normal hip and 10.9% in LCPD. In abduction with external rotation, it was 8.3% in normal hip and 12.4% in LCPD. 4. In normal hip, the containment ratio was more than 1.0 in any position of hip, but the containment ratio was 1.03 in abduction with internal rotation and 0.95 in abduction with external rotation of hip in LCPD. 5. On the basis of these results, efficacy of the Scottish Rite orthosis was doubtful in most hips of LCPD.

Idiopathic small bowel ulceration occurring beyond the duodenum is rare, and less than 5% of all the reported cases have occurred in children. In most of the cases, single ulcer of unknown cause is observed in jejunum or ileum. The diagnosis is difficult and usually made at the time of surgical exploration for the complications, such as perforation, hemorrhage or obstruction. We experienced a case of perforation of idiopathic ileal ulceration due to blunt abdominal trauma in a 11-year-old boy. The ileal segment including the lesion was resected and the pathologic findings were compatible with idiopathic small bowel ulceration. The clinical and pathological aspects are discussed, and the literatures were reviewed.
