RESUMEN

Congenital anomalies of the large vessels are rare. Left inferior vena cava is the second most common anomaly after duplication. They are a challenge that some Departments of Urology and Vascular Disease face. We report the case of a patient admitted for kidney transplantation in whom left inferior vena cava was detected on radiological evaluation performed in the preoperative period.

RESUMEN

Disorders of sex differentiation cause a discrepancy between sex itself (phenotype) and genetic sex (genotype) which poses a problem in sex determination. In lower socioeconomic level countries where prenatal diagnosis is often absent and technical equipments are inadequate, medical and surgical management is difficult. The aim of this study is to clarify the role of laparoscopy in the management of sexual ambiguity through observation of 4 cases and review of the literature.

RESUMEN

A multivesicular hydatid cyst was removed from the left kidney of a 26-year-old woman by retroperitoneal laparoscopy to avoid contamination of the abdominal cavity. A scolicidal agent (20% hypertonic saline) was injected around the kidney initially and then instilled into the cyst after the contents had been evacuated. There were no complications and no anaphylactic shock. This appears to be the first reported case of treatment of renal hydatid cyst by laparoscopy.

RESUMEN

Adrenal myelolipoma is a rare, benign, non-secreting tumour composed of adipose and haematopoietic tissue. The authors report a rare case of giant adrenal myelolipoma in a 53-year-old patient presenting with low back pain and a palpable flank mass on examination. CT scan suggested the diagnosis and surgical resection was indicated in view of the size and symptomatic nature of this mass. Histological examination confirmed the diagnosis. The outcome was favourable without recurrence after a follow-up of one year. The diagnosis of adrenal myelolipoma is based on radiology. Conservative management is generally sufficient for small asymptomatic tumours, but resection is required for large (> 5 cm) and/or symptomatic tumours.

RESUMEN

The male urethral diverticulum is a rare affection. The authors report one case of congenital urethral diverticulum. The diagnosis was approved by clinical examination and urethrocystography. Treatment was based by resection of the diverticulum and urethrography. On the basis of this case, the authors discuss the incidence, diagnosis and therapeutic aspects of this disease.

RESUMEN

The authors report a new case of retroperitoneal ganglioneuroma in an 18-year-old girl presenting with abdominal mass and lumbosciatica. The diagnosis of retroperitoneal tumour was based on computed tomography and magnetic resonance imaging. Treatment consisted of complete resection of the tumour. The postoperative course was favourable with no recurrence after one year of follow-up. The authors discuss the diagnostic, therapeutic and prognostic aspects of this disease.

RESUMEN

Buske-Lowenstein tumour (BLT) is a giant condyloma acuminata characterized by a potential for malignant transformation and invasion and recurrence after treatment. It is a rare viral disease, essentially transmitted by sexual intercourse. The objective of this study was to evaluate the epidemiology, clinical features, classification and prognosis of this disease and to outline the treatment modalities. The authors report 3 unusual cases of Buske-Lowenstein tumour involving the scrotum in 2 cases and associated with malignant transformation in 1 case. All three patients (1 woman and two men) presented a history of high-risk sexual behaviour. BLT was confirmed by biopsy and was treated by complete surgical resection. The postoperative course was uneventful without recurrence. Treatment has not been clearly defined and is essentially based on surgery. Sexual education and early treatment of condylomatous lesions can improve the prognosis of this disease. In the light of these cases, the authors emphasize the importance of prevention for all sexually transmissible infections based on sexual education.

RESUMEN

The authors report a new case of Stauffer syndrome characterized by cholestatic jaundice in a 54-year-old patient with renal tumour. This paraneoplastic syndrome resolved after nephrectomy. The authors discuss the pathophysiological, diagnostic and therapeutic aspects in the light of a review of the literature.

RESUMEN

The authors report a case of adrenal tuberculosis discovered during staging of a biopsy-confirmed bladder tumour, in a 70-year-old patient consulting for haematuria. Cystoscopy with biopsy revealed a high-grade papillary urothelial carcinoma invading the detrusor. Staging abdominopelvic computed tomography revealed a necrotic, multilobed right adrenal mass. Histological examination of the adrenalectomy specimen revealed adrenal tuberculosis. Antituberculous therapy was administered for 9 months and comprised streptomycin, isoniazid, rifampicin and pyrazinamide for 2 months, followed by rifampicin and isoniazid for 7 months. In the light of this case and with the increasing incidence of AIDS, the diagnosis of adrenal tuberculosis must be considered in any case of incidentaloma.
