Pseudolymphoma, the term clinically synonymous with pseudotumor, is one of the lymphoproliferative disease which frequently causes unilateral proptosis in adults. The clinical manifestations and the pathologic pictures may resemble that of a true neoplasm. Recently, immunologic methods such as immunofluorescent and immunohistochemical study were popularly used in the diagnosis and study of lymphoproliferative diseases. We have experienced three cases of pseudolymphoma of the orbit which were diagnosed with PAP(proxidase-antiperoxidase) stain of the immunohistochemical method.

A clinical study on the AC/A ratio with 125 normal persons was performed by modified gradient method. AC/A ratio is a convergence response of an individual to a unit stimulus of accommodation. Through many studies on the AC/A ratio, the normal range of the AC/A ratio was 3 delta/D ~ 5 delta/D. The AC/A ratio can be changed by some drugs. The AC/A ratio is high in divergence excessive exotropia, pseudodivergence exotropia and non-refractive accommodative esotropia; on the other hand, the AC/A ratio is low in convergence insufficiency exotropia. Methods for the determination of the AC/A ratio are heterophoria method, gradient method, fixation disparity method. This study was performed by modified gradient method due to easy application. The mean of the AC/A ratios in this study was 4.55 delta/D, and the AC/A ratios ranged from 0.5 delta/D to 9.6 delta/D. 95 percentile ranged from 3.01 delta/D to 6.09 delta/D. The AC/A ratio in this study seems not to be correlated with age, sex and interpupillary distance.

Cellular schwannoma is a variant of schwannoma, and is diagnosed as malignant tumor in over one fourth of cases because of its cellularity, mitotic activity and the occasional presence of bone destruction. This tumor is a tumor with low malignant potential and usually occurs in peripheral nervous system, mainly in the posterior mediastinum and retroperitoneal space. But pelvic retroperitoneal cellular schwannoma is very rare. Recently, we experienced a case of pelvic retroperitoneal cellular schwannoma in a 42-year-old woman; in reporting the case a brief review of the literature is included.

The oculopharyngeal muscular dystrophy is a distinct, clinically well-defined myopathy of later life inherited in an autosomal dominant fashion with complete penetrance. Blepharoptosis, dysphagia, lower leg weakness are the most prominent findings. It is a systemic myopathy which affects all voluntary muscles and appears to spare smooth and cardiac muscle. The authors experienced a case of the oculopharyngeal muscular dystrophy which showed characteristic signs and symptoms such as symmetric ptosis, dysphagia, and progressive external ophthalmoplegia, and the literature were reviewed.

71 years old man was operated on due to abdominal aortic aneurysm associated with complete occlusion of left common iliac artery.The coexisting chronic deep vein thrombosis of the left femoral and iliac vein was not diagnosed preoperatively.Resection of aneurysm and Y-graft interposition was performed.Recurrent edema and pain occured to the left lower extremity immediately postoperatively,which aggrevated with the lapse of time,resulting in fatal extensive venous thrombosis.This report regards the surgical treatment and complication of the aortoiliac occlusive disease associated with chronic deep vein thrombosis.

PURPOSE: Laparoscopic donor nephrectomy is associated with less postoperative pain and faster recovery times in living kidney donors. However, pneumoperitoneum, which is required in laparoscopic donor nephrectomy, can result in adverse effects on renal function in donors and recipients. We compared renal function in donors and recipients after hand-assisted laparoscopic donor nephrectomy (HALDN) and open donor nephrectomy (ODN). MATERIALS AND METHODS: Between January 1997 and January 2008, 241 live donor nephrectomies were performed by either HALDN (n=118) or ODN (n=123). Preoperative patient characteristics were not significantly different between the donors and recipients. We monitored the changes in serum creatinine levels of the donors and recipients preoperatively and on postoperative days 1, 5, 28, 84, and 365. RESULTS: The mean operative times of HALDN and ODN were 171 and 163 minutes (p=0.284), and the mean warm ischemic times were 292 and 236 seconds (p=0.207), respectively. The mean serum creatinine level in the recipients on postoperative day 1 was significantly higher after HALDN than after ODN (3.48 vs. 2.62 mg/dl, p=0.003). However, from postoperative day 5 to 1 year, there was no significant difference between the two groups. The mean serum creatinine level in the donors was not significantly different between the HALDN and ODN groups throughout the study period. CONCLUSIONS: Renal function recovery in the donors was similar with both HALDN and ODN. Graft renal function recovery after HALDN was comparable with that after ODN, except immediately after surgery (postoperative day 1).

Carcinoma of the prostate is a common malignancy affecting elderly men. Lung metastasis from prostate cancer occurs frequently, but tumor metastasis to the central bronchi that clinically mimics primary bronchogenic carcinoma are very rare. We report a 73-year old man with endobronchial metastasis from prostatic carcinoma presented with respiratory symptom cough. Diagnosis of issues taken from materials which were used for bronchoscopic biopsy and prostate biopsy and immunohistochemical staining for prostate specific antigen(PSA) confirmed a case of endobronchial metastasis from prostatic carcinoma. Hormonal therapy(LHRH agonist) was applied to this patient.

PURPOSE: Several studies have demonstrated the superiority of endorectal coil magnetic resonance imaging (MRI) over pelvic phased-array coil MRI at 1.5 Tesla for local staging of prostate cancer. However, few have studied which evaluation is more accurate at 3 Tesla MRI. In this study, we compared the accuracy of local staging of prostate cancer using pelvic phased-array coil or endorectal coil MRI at 3 Tesla. MATERIALS AND METHODS: Between January 2005 and May 2010, 151 patients underwent radical prostatectomy. All patients were evaluated with either pelvic phased-array coil or endorectal coil prostate MRI prior to surgery (63 endorectal coils and 88 pelvic phased-array coils). Tumor stage based on MRI was compared with pathologic stage. We calculated the specificity, sensitivity and accuracy of each group in the evaluation of extracapsular extension and seminal vesicle invasion. RESULTS: Both endorectal coil and pelvic phased-array coil MRI achieved high specificity, low sensitivity and moderate accuracy for the detection of extracapsular extension and seminal vesicle invasion. There were statistically no differences in specificity, sensitivity and accuracy between the two groups. CONCLUSION: Overall staging accuracy, sensitivity and specificity were not significantly different between endorectal coil and pelvic phased-array coil MRI.

STUDY DESIGN: Case report. OBJECTIVES: To report a case of epidural hematoma following cervical spinal fracture in a patient with ankylosing spondylitis. SUMMARY OF LITERATURE REVIEW: An early surgical intervention for acute epidural hematoma following cervical spinal fracture led to improvements in the patient's neurological deficits. MATERIALS AND METHODS: A 76-year-old male with ankylosing spondylitis presented with neck pain and motor weakness of both upper and lower extremities after falling. He sustained fractures of the C7 body and the spinous processes of C5 and C6. Magnetic resonance imaging showed an extensive epidural hematoma from C7 to T5. The authors performed decompression from C6 to T2, and posterior instrumentation and fusion from C4 to T3. RESULTS: An urgent surgical intervention was performed, and a good result was obtained. CONCLUSIONS: The authors describe an early surgical intervention in a case of acute epidural hematoma following cervical spinal fracture in a patient with ankylosing spondylitis.
