[Pedunculated Giant Condyloma Acuminatum of the Scrotum].

The patient was a 71-year-old male whose chief complaint was a scrotum mass. The mass had gradually increased in size without any associated symptoms. The physical examination revealed a pedunculated, radish brown, and elastic soft tumor (4. 5×3. 5×3. 0 cm) in the right scrotum. Blood chemical analysis of HbA1c and squamous carcinoma antigen were 8. 3% and 38. 4 ng/ml (≦1. 5), respectively. This tumor was successfully treated with surgical resection. Histopathological examination showed condyloma acuminatum without malignant findings. Giant condyloma acuminatum commonly affects the genital and perianal areas. An immunocompromised state generally exists in the background of the patients.

Application of the indocyanine green fluorescence imaging method in laparoscopic resection of a solitary retroperitoneal metastasis of renal cell carcinoma: A case report.

Fluorescence image-guided surgery has improved intraoperative identification of anatomic structures including visualization of vascular anatomy. Herein, indocyanine green (ICG) fluorescence imaging was applied to identify of a recurrent small tumor of renal cell carcinoma (RCC) during laparoscopic surgery. The patient underwent left laparoscopic radical nephrectomy via the retroperitoneal approach for RCC (clear cell carcinoma, pT1bN0M0) at the age of 39 years. A solitary retroperitoneal mass (14 mm in diameter) was identified in a computed tomography scan 6 years after surgery. We performed laparoscopic resection with the application of the ICG angiography, because RCC is recognized as one of the most hypervascular cancers. The tumor was clearly visualized by fluorescence. Histopathological diagnosis of the resected tumor was recurrent RCC (low grade, G1). The patient remained free of disease at 2 years after surgery. The ICG fluorescence imaging would be a useful method for identification of metastatic small lesions of RCC during laparoscopic surgery.

[URETEROSCIATIC HERNIA TREATED BY URETERAL STENT PLACEMENT].

Ureterosciatic hernia is an uncommon condition that can cause ureteral obstruction. Here, we report a case of ureterosciatic hernia successfully treated by ureteral stent placement. A 95-year old woman presented to our emergency department with high fever. An abdominal CT scan revealed mild left hydronephrosis and urinalysis identified pyuria. The patient was subsequently admitted to hospital with a diagnosis of complicated pyelonephritis. No recovery was evident after antimicrobial treatment, a repeat CT scan revealed a ureterosciatic hernia. We indwelled a left ureteral stent and repaired the hernia. We did not opt for a surgical approach because of the patient's age and presence of dementia. The stent was removed after 2 months, but the patient was re-admitted 4 months later because of pyelonephritis. Here, we indwelled a left ureteral stent, and the patient underwent regular ureteral stent exchange. Placement of a ureteral stent for ureterosciatic hernia is an effective treatment for elderly patients and those who are poor surgical candidates.
