PURPOSE: Racemose hemangiomas of the retina are rare developmental vascular anomalies with abnormal arteriovenous anastomoses. We report our observations of a retinal racemose hemangioma with marked dilation and tortuosity of the retinal vessels in the entire left retina. METHODS: In a 9-year-old boy with loss of vision and mild esotropia who presented with hugely dilated and tortuous retinal vessels in left retina, we examined fundus, fluorescein angiography, cerebral angiography, brain CT and MRI. RESULTS: Fundus and fluorescein angiography of the left eye showed marked dilation and tortuosity of the retinal vessels. Angiographic finding showed rapid filling of all vessels and no dye leakage. MRI finding revealed small tortuous vessels around left optic nerve, optic chiasm and tract. Brain CT and cerebral angiography showed nothing abnormal.

Blunt thorax trauma may produce a variety of cardiac lesions, which may occur alone or in combination. Nonpenetrating perforation of interventricular septum with chordae rupture of tricuspid valve is a infrequent pathologic event. A 40-years-old worker was transfered to hospital with increasing symptoms of right heart failure following a blunt compressing chest trauma with a huge overolling cement pipe(Wt.680kg) 6 weeks ago. The immediately diagnosed serial rib fracture of the left thorax cage and dislocation of the left acromoclavicular joint were treat conservatively. A conventional transthoracic color Doppler and two dimensional echocardiogram detected traumatic ventricular septal defect with bilatral shunt and tricuspid regurgitation. An additional transesophageal color echocardiopraphic demonstrated the ruptured chordae tendineae of the tricuspid septal leafet, which prolapsed deeply into the right atrium. The conventional color Doppler echocardiopraphy enhances the ability to detect the presence of a ventricular septal perforation and valve dysfunction in a patient with cardiac contusion. The transesophageal echocardiopraphy is a useful semiinvasive tool for the detailed morphological evaluation of atrioventricular valves and their substructure.

Testicular biopsy has been known as very useful diagnostic procedure for the male infertility. For the past 9 months percutaneous testicular biopsy procedures were attempted on 64 patients with azoospermia or atrophic testis using a new Tru-Cut biopsy needle. In addition surgical testicular open biopsy procedure on one side and percutaneous testicular needle biopsy procedure on the other side were performed in comparison with two techniques. Biopsy specimens were fixed in Bouin solution. They were stained and histologically examined. Results were summarized as follows: Numbers of seminiferous tubules obtained by needle biopsy technique were found to be fewer than that of the tubules obtained by open biopsy technique. But diagnostic accuracy was not compromised by the needle biopsy technique. There was no bleeding either from the testis or scrotum, no extusion of testicular tissue from the puncuate site. In conclusion percutaneous testicular biopsy using Tru-Cut biopsy needle has been proved to be simple, time saving, less expensive and accurate method for testicular biopsy.

Number of germ cells in the seminiferous epithelium was analyzed quantitatively in testicular biopsy specimens of 23 patients without ductal obstruction and of 4 patients with ductal obstruction. Roth number of mature spermatids within each cross-section of seminiferous tubule and number of atrophic tubule were counted in biopsy specimens. Results were expressed as cell number of mature spermatids per seminiferous tubule and percentage of atrophic tubules. A significant correlation was demonstrated between sperm density and mature spermatid counts. Patients with sperm counts of less than 40 x l0(6)/ml had mature spermatids counts of less than 25 per seminiferous tubule. Coefficients of correlation between mature spermatid count and percentage of atrophic tubules were higher than those of correlation between sperm counts and percentage of atrophic tubules. In asoospermrc patients with epididymal obstruction, sperm count after corrective surgery could be predicted correctly by this quantitative analysis technique of testicular biopsy specimens and partial obstruction of anastomotic site of seminal tract could be proved in oligozoospermic patients after corrective surgery.

From 1980 to 1989, 144 patients underwent radical nephrectomy for renal cell carcinoma. Survival was analyzed in terms of pathologic stage and histologic grade. Data revealed that M category was the most important prognostic factor followed by, in order of importance, T category, N category, and grade. But grade as prognostic factor in renal cell carcinoma needs additional investigation. Stage pT1 and pT2 showed similar survival rate. The separation of pT1 and pT2 according to size of the primary tumor may not be a meaningful prognostic variable. Because vascular invasion may occur with tumors of various size, separating components into a description of the tumor (T), nodes (N), metastases (M) and renal vein involvements (V) makes good sense. The prognostic value of lymphadenectomy is limited by the fact that the tumor metastasizes through the blood stream and the lymphatic system with equal frequency.

Wegener's granulomatosis is a systemic necrotizing vasculitis of unknown cause. The disease is characterized by the involvement of the upper airway, the lung, and the kidney. Skin lesions are frequent and the most common lesion is purpura distributed on the limbs and trunk. A 34-year-old female showed recurrent purpuric macules on the both lower extremities and buttocks. The patient. showed nasal septal perforation with saddle nose deformity and C-ANCA positivity. Histopathologic findings of purpuric lesion revealed the features of necrotizing vasculitis. The histologic specimen from the nasal cavity showed chronic inflammation with granuloma formation and kidney showed focal necrotizing glomerulonephritis. Therefore, we treated the patient with prednisolone and cyclophosphamide having diagnosed Wegener's granulomatosis.
