Castleman's disease. A rare cause of isolated retroperitoneal mass.

OBJECTIVES: We describe a case of hyaline vascular type Castleman 's disease with unifocal presentation as retroperitoneal mass. We describe the pathological and radiological findings and present a bibliographic review. METHODS: Castleman's disease is a rare benign disease of unknown etiology characterized by a lymphoproliferative disorder. Two clinical types have been described: localized and multicentric. Isolated retroperitoneal involvement is uncommon. RESULTS: 39-year-old female who complained of back pain. Abdominal CT scan identified a 5 cm retroperitoneal interaortocaval mass. Complete laparoscopic excision was performed. Pathological study showed localized angiofollicular hyperplasia (hyaline vascular type Castleman's disease). CONCLUSIONS: The presentation of Castleman's disease as isolated retroperitonealmass is quite rare and should be distinguished from other retroperitoneal lesions of malignant character. The treatment of choice is surgery, providing a definitive and curative diagnosis. Operative biopsy may be useful.

Holmium laser treatment for low grade, low stage, noninvasive bladder cancer with local anesthesia and early instillation of mitomycin C.

PURPOSE: We evaluated the results of laser photocoagulation of recurrent low stage noninvasive bladder cancer. MATERIALS AND METHODS: The study included 36 patients with a recurrent superficial papillary tumor within 1 year of endoscopic resection. Patients underwent laser photocoagulation of the recurrence under local anesthesia and sedation. They received early instillation of 40 mg mitomycin C and were discharged home without a catheter a few hours after the operation. Patients completed a visual analog scale to quantify the perceived level of pain, including 1--no pain to 10--maximum pain. Patients were reviewed after 3, 6 and 12 months to evaluate tumor recurrence. RESULTS: The mean and median visual analog scale score was 3 points (range 1 to 10). No patient had urinary infection or a catheter at hospital discharge. The incidence of recurrence at 12 months was 25%, mainly in the first 15 cases. CONCLUSIONS: Laser photocoagulation with local anesthesia and sedation is easy to perform and well tolerated. There were no complications and the recurrence rate was similar to that of transurethral resection, as calculated using the recurrence calculator of the 2006 guidelines on TaT1 (nonmuscle invasive) bladder cancer from the European Association of Urology.

[Intraureteral foreign body]. / Cuerpo extraño intraureteral.

OBJECTIVE: We present a rare localization for a foreing body in the urinary system, and review the bibliography to know about it existence, frequency and localization. METHODS: We present the case of a 49 year old woman who referreds she had introduced a metallic objet in her genital area. RESULTS: After the necessary tests, we could see a metallic cylinder. It was 8 cm long and was localized inside the right pelvic ureter. CONCLUSIONS: The presence of strange bodies in the urinary system is a rare urological emergency. Treatment is the key element of the extraction of the least bloody way possible.
