Acrospiroma is a rare benign tumor and a clinicopathologically distinctive neoplasm differentiating toward the distal part of the eccrine sweat gland. I experienced a case of dermal acrospiroma in a 59-year-old man who had a 7.0x6.5 x 5.3 cm sized, slowly growing, brown colored, smooth-surfaced mass on the right scrotum for 3 years. Histological examination revealed lobular structures composed of small fusiform cells and large eosinophilic polyhedral cells. Histochemically some of large polyhedral cells had PAS-positive DPAS-negative glycogen and Alcian-positive mucin in cytoplasm. Immunohistochemical stainings for vimentin, S-100, low molecule keratin, and EMA were positive in the tumor cells. During 6 months follow up period after excision, there was no recurrence. However, it is necessary to follow up for a long period because some acrospiroma may recur after a long silence period.

PURPOSE: To determine if the urine specific gravity(SG) plays a role in enuresis, the first morning urine SG of the healthy preschool nocturnal enuretic was compared with that of the nonenuretic. The results of desmopressin were analyzed according to the pretreatment urine SG to know if the urine SG can predict the responsiveness of the medication. MATERIALS AND METHODS: Five hundred twenty healthy preschool children aged 3-6 years were entered in this prospective observer-blinded study. A comparison was made between SG of the first morning urine specimen and results of questionnaire concerning the bed wetting and voiding habits of children. The responsiveness to oral desmopressin(0.2-0.4mg h.s.) in 14-day treatment periods was also analyzed according to the urine SG in 28 children with enuresis. The responder group was defined as a reduction of at least 50% from the number of wet night. RESULTS: The incidence of enuresis was 8.6 percent. Stastistically significant difference was found between the bedwetter and nonbedwetter group with regard to the urine SG(p<0.05). The overall response rate of desmopressin was 68 percent. There was no significant difference between the responder and nonresponder group with respect to urine SG. CONCLUSIONS: The first morning urine of the enuretic showed higher probability of lower level of the SG than that of the nonenuretic. Treatment with desmopressin was associated with a significant decrease in the number of wet night, but clinical response was not predictable based on the first morning urine SG.

PURPOSE: Penile paraffinoma provokes many serious undesirable effects. We studied our series retrospectively to evaluate the outcome of surgical treatment according to the degree of penile skin defect after excision of the lesion. PATIENTS AND METHODS: Surgical treatment for penile paraffinoma was performed in 42 patients over 6 years. The operative methods were complete excision with primary closure (N=34) or bilateral pedicle scrotal flap (N=8). RESULT: The complications of bilateral pedicle scrotal flap were wound infection in 1 case and skin defect in 1 case. There were no complications of primary closure. CONCLUSIONS: We propose that the proper treatment of penile paraffinoma is complete excision with primary closure for a small denuded penis and bilateral pedicle scrotal flap for a large denuded penis.

Surgical results of 34 children (68 ureters) who underwent Cohen ureteral reimplantation in the last 6 years were evaluated. All children were followed at least 4 months after the operation. Indication for the repair consisted of vesicoureteral reflux in 22 children, obstructive megaureter in 8 children and ureterocele in 4 children. The underlying problems in 55 ureters ( 94.8% ) were successfully corrected. Surgical failures were persistent reflux in 2 ureters, new ipsilateral reflux in 1 ureter and contralateral reflux in 1 ureter. However, no ureteral obstruction was noticed in this series. In conclusion, the Cohen cross trigonal technique was a safe and effective method of ureteral reimplantation in children.

PURPOSE: We compared the recurrence rate and mean interval to recurrence according to tumor grade after complete transurethral resection and adjuvant intravesical instillation with bacillus Calmette-Guerin (BCG), in patients with stage T1 transitional cell carcinoma of the bladder. MATERIALS AND METHODS: Between January 1994 and May 2000, 31 patients presenting to our hospital with T1 superficial bladder cancer received adjuvant intravesical instillation with BCG after complete transurethral resection of the bladder tumor. Tumors with CIS lesion or recurrent tumors were excluded. The recurrence rates, mean interval to recurrence, tumor size and number of tumors were compared according to tumor grade. RESULTS: Of the 31 patients, 5 presented with grade I tumor, 17 with grade II tumor and 9 with grade III tumor. Mean follow-up period was 22 months (range 6-58) and mean tumor sizes according to tumor grade were 1.6, 1.6 and 1.7cm in grade I, II and III, respectively. Twelve (38.7%) patients experienced tumor recurrence. The recurrence rates according to tumor grade were 20.0%, 41.2% and 44.4% in grade I, II and III, respectively. Mean interval to recurrence were 40, 11.4 and 7.5 months, respectively. CONCLUSIONS: Our results suggest that the recurrence rates were higher in grade II and III tumors than in grade I tumor. Therefore close follow-up is necessary in both grade II and III tumors.

PURPOSE: The aim of this study was to estimate the current prevalence of varicocele and their effect on the testicular volume. MATERIALS AND METHODS: The relationship between testicular volume and the degree of varicocele, as classified by Dubin-Amelar, was evaluated in 1,281 Korean school boys, between 15 and 18 years of age. All examinations were carried out by a single urologist, and the testicular volume was measured in the upright posture using a Prader's orchidometer. All the boys were assessed for their previous medical history, family history. RESULTS: There was a 12.9% prevalence of varicocele in the adolescents. The mean testicular volume in the control groups was 14.29+/-2.10ml on the left and 14.45+/-2.13ml on the right. Patients with left varicocele had a testicular volume of 13.09+/-2.34ml on the left and 13.24+/-2.32ml on the right. The testicular volume of patients with a grade I varicocele were similar to those in the control group. Patients with grade II and III varicoceles had significantly smaller testes than the control groups. CONCLUSIONS: The reduction in testicular volume due to a varicocele correlated with the severity of the varicocele grade. Careful evaluation for testicular volume loss, and early surgical intervention, should be offered to adolescent patients with varicoceles.
