The glomus tumor is a distinct neoplasm composed of modified perivascular smooth-muscle cells identical to those described in the glomus body. Malignant glomus tumor, also referred to as glomangiosarcoma, is exceedingly rare. It has been subdivided into locally infiltrative glomus tumor, glomangiosarcoma arising in a benign glomus tumor, and glomangiosarcoma arising in de novo. A few cases of malignant glomus tumor arising in a benign glomus tumor have been reported. A 55-year-old man underwent resection of a solitary nodule in the right shoulder area. The tumor was biphasic with a typical benign glomus tumor at the periphery and the central sarcomatous area composed of oval to elongated pleomorphic cells with a single prominent nucleolus and occasional mitotic figures. Both tumor components showed intense staining for vimentin, smooth muscle actin, and muscle specific actin. Herein, we report a case of a malignant glomus tumor arising in a benign glomus tumor with an immunohistochemical study and a review of literatures.

Three patients with primary non-Hodgkin's lymphoma of the uterine cervix are reported and the literature is reviewed. All the three patients in the current study presented with vaginal bleeding. They were found to have diffuse large cleaved cell lymphoma, one of which was multilobated variant with marked sclerosis. Histologically, differential diagnsis from undifferentiated small cell carcinoma, endometrial stromal sarcoma & other sarcomas was difficult and requires special stains including immunobistochemical study. Vaginal pap smears were diagnosed as 'class V; malignant lymphoma' in only one patient. Immunologically, two cases were beta-cell lineage and one case was T-cell lineage. All the patients were treated with chemotherapy only and showed good responses.

In the studies on the hatching mechanisms in mammals, many investigators focused on the embryonic intrinsic factor(s) in in vitro culture, but the uterine environment as the extrinsic factor(s) is thought to play an important role in hatching mechanism. Therefore, to evaluate the effect of uterine environment on the hatching event in vivo, the immature(GV) and ovulated(MII) oocytes, and the late 2-cell embryos of mouse were transferred to pseudopregnant foster mother's uterus during peri-implantation period. So it was verified whether there would happen hatching by only uterine environment independently on embryonic stage. The ultrastructural changes of the zona surface of transferred group were compared with those of in vivo and vitro group by SEM. 36 hrs after transfer, the immature and ovulated oocytes almost degenerated, and the late 2-cell embryos developed to various embryonic stages. However, the embryos which didn't develop to blastula stage did not hatch. The ultrastructural network of ZP in transferred group seemed to be smoothed uniformly, which was different from in vitro group. In conclusion, it is suggested that the uterine environment during peri-implantation period enhances the embryo hatching by provoking the structural change of ZP.

PURPOSE: The purpose was to describe comparative analysis of the surgical outcome of percutaneous K-wire fixation of bony mallet fingers reduced with towel clip and 18-gauge needle. METHODS: We analyzed the bony mallet finger patients with more than twelve months follow-up after percutaneous K-wire fixation. The patients were randomly divided into two groups. Eighteen fingers were treated with closed reduction using towel clip and 18 other fingers were treated with closed reduction using 18-gauge needle. RESULTS: Radiographs showed bony union and no subluxation in all cases after K-wire removal. The average extension lag was 2.8degrees/1.9degrees, and range of motion of distal interphalangeal joint was 70.3degrees/75degrees respectively. According to Crawford's criteria, excellent results were obtained in 9/11 fingers, good results in 8/7 fingers, and poor result in 1/0 finger, respectively. CONCLUSION: 18-gauge needle reduction in percutaneous K-wire fixation is considered less invasive and useful method for treatment of bony mallet finger with comparable results with towel clip reduction.

STUDY DESIGN: In this study, 18 patients undergoing posterior lumbar interbody fusion for multilevel lumbar spinal stenosis associated with degenerative scoliosis were reviewed retrospectively. OBJECTIVES: To assess the effectiveness of the cage-instrumented posterior lumbar interbody fusion in multilevel lumbar spinal stenosis associated with degenerative scoliosis. SUMMARY OF LITERATURE REVIEW: Degenerative lumbar scoliosis with the problems of neurogenic claudication, mechanical back pain and spinal deformity present a challenge for treatment. MATERIALS AND METHODS: We reviewed 18 surgical cases of multilevel lumbar spinal stenosis with degenerative scoliosis from March 1995 to April 2000 with an average follow up period of 2.9 years. We assessed the radiographic results of scoliotic angle correction and sagittal angle correction of the maximum curve and fused segment and disc height restoration. Clinical results were evaluated according to the Kirkaldy-Willis criteria. RESULTS: Mean scoliotic angle at preoperative, postoperative and final follow-up (maximum curve/fused segment) was 17.7-6.1-7.3degree /15.0-5.8-6.1degree respectively. Mean sagittal angle corresponding to each period was 12.1-34.1-32.7degree /8.3-27.0-26.0degree respectively. Mean disc height corresponding to each period was 22.9-42.4-40.5% respectively. The clinical result was analyzed as 15 satisfactory (83.3%), 3 fair (16.7%) and no poor. Fusion success was achieved in all patients. There were no serious complications except one case of fusion extension distally and no significant curve progression within follow-up period. CONCLUSIONS: The cage-posterior lumbar interbody fusion in multilevel lumbar spinal stenosis with degenerative scoliosis was effective for correction of scoliotic and sagittal deformity and restoration of disc height with resultant foraminal patency, provided relatively high clinical success and in situ fusion success in all cases even over multiple fusion levels, and can be an alternative among surgical treatments of this complex disease.

PURPOSE: The purpose of this study is to evaluate the clinical results of retrograde intramedullary fixation of metacarpal shaft fractures using two pre-bent Kirschner wires. MATERIALS AND METHODS: Between March 2006 and May 2008, 19 cases (17 patients) of metacarpal shaft fractures were treated with the retrograde intramedullary Kirschner-wire fixation and followed at least one year. The exclusion criteria were thumb metacarpal fractures, comminuted fractures and irreducible metacarpal spiral shaft fracture by closed manipulation. At final follow up all the cases were assessed with total active motion(TAM), rotational deformity, bony union and angular deformity based on the plain radiographes. RESULTS: At the last follow-up, all cases achieved bony union. Five cases showed less than 5degrees of dorsal angular deformity. The average union period was 6.3 weeks (range, 5-9weeks). Fifteen cases (79%) showed excellent results, four cases good results based on TAM. No case showed rotational deformity. Two cases had skin irritation by distal wire end, which was subsided after wire removal. CONCLUSIONS: In patients with a metacarpal shaft fracture, retrograde intramedullary fixation using two pre-bent K-wires can provide satisfactory clinical results.

PURPOSE: To evaluate the clinical results of the treatment of the percutaneous Kirschner wire fixation of bony mallet finger using an 18 gauge needle. MATERIALS AND METHODS: From September 2002 to September 2009, we performed closed reduction using an 18 gauge needle and percutaneous fixation with Kirschner wire for 15 cases of bony mallet finger and followed up at least 1 year. The fractures were classified by the Wehbe and Schneider's method. Indications of operative treatment were fractures involving more than 30% of articular surface, fracture fragments displaced more than 3 mm, or subluxation of the distal interphalangeal joint. The results were evaluated by the Crawford criteria. RESULTS: All the fractures united, with an average healing time of 5.3 weeks(4-6 weeks). According to Crawford criteria, 10 cases were excellent, 5 cases were fair at a mean follow-up of 13 months. There were no pin tract infections and migrations of the pin. CONCLUSION: Percutaneous Kirschner wire fixation of mallet finger using an 18 gauge needle is an easy technique which can achieve anatomical reduction and diminish operation-related complications.

PURPOSE: To assess the results of an arthroscopic repair for traumatic peripheral tears of triangular fibrocartilage complex (TFCC, Palmer type Ib). MATERIALS AND METHODS: 10 patients with traumatic peripheral TFCC tear were treated with outside-in technique with arthroscope and evaluated with an average follow-up of 19 months (range, 15 to 28 months). The clinical outcomes were assessed with investigation of pain, range of motion, grip strength, return to job and patient's satisfaction. RESULTS: The arthroscopic repair of traumatic peripheral TFCC tear resulted in significant pain relief and increase in functional ability of wrist, that is, 8 excellent, 1 good and 1 fair results. At last follow-up, the average of flexion was 79° (range 76~86°), average of extension was 78° (range 70~84°), average pronation was 85° (range 75~91°) and average supination was 87° (range 79~92°). Nine patients except one were back to their original job. CONCLUSION: Arthroscopic repair of traumatic peripheral TFCC tear could be used for pain relief and increase in functional ability of wrist.
