[Paratesticular adenomatoid tumor: a report of nine cases]. / Tumor adenomatoide paratesticular: una serie de nueve casos.

INTRODUCTION: Paratesticular tumors are rare. Most of them are benign, and adenomatoid tumors are most common. These tumors sometimes infiltrate the testicular parenchyma and require differential diagnosis with malignant tumors. In such cases, intraoperative biopsy allows for performing conservative surgery. MATERIALS AND METHODS: A retrospective study of nine patients with paratesticular adenomatoid tumors seen during a nine-year period (2000-2008) is reported. RESULTS AND CONCLUSIONS: Patient age (mean, 49.6 years) and most common initial signs (tender nodule) are reported. The tumor most commonly occurred as a small, usually oval, nodule in the tail of epididymis. Our series included a case each of intraparenchymal tumor of the testis and tumor of the tunica vaginalis. Diagnosis was initially made based on a ultrasound scan and subsequently confirmed by histology. Differential diagnosis and surgical treatment, performed in all patients, are reported, and also the pathological features of surgical specimens.

Tumor adenomatoide paratesticular: una serie de nueve casos / Paratesticular adenomatoid tumor: a report of nine cases

Introducción: los tumores paratesticulares son raros. La mayoría son benignos, siendo el más frecuente el tumor adenomatoide. En ocasiones estos tumores infiltran el parénquima testicular y es necesario plantear un diagnóstico diferencial con tumores malignos, por lo que la biopsia intraoperatoria, en estos casos, permite realizar una cirugía conservadora. Material y métodos: presentamos de forma retrospectiva nuestra extraordinaria serie de 9 casos de tumores adenomatoides paratesticulares durante un periodo de 9 años (2000- 2008). Resultados y conclusiones: describimos la edad de los pacientes (media de 49,6 años) y la clínica de inicio (nódulo palpable doloroso). La localización de la lesión más frecuente fue en el epidídimo, que habitualmente se manifiesta como un nódulo de pequeño tamaño, generalmente oval en la cola del epidídimo. En nuestra serie tenemos un caso de lesión testicular intraparenquimatosa y otro en túnica vaginal; el resto se localizan en el epidídimo. El diagnóstico de sospecha fue por ecografía, con confirmación histológica posterior. Describimos el diagnóstico diferencial y el tratamiento quirúrgico, que se aplicó en el 100% de los casos, así como sus características anatomopatológicas(AU)

[Xanthogranulomatous pyelonephritis in childhood. A case report]. / Pielonefritis xantogranulomatosa en la infancia. A propósito de un caso.

Xanthogranulomatous pyelonephritis is an uncommon chronic inflammatory renal disorder. Most cases have been described in middle aged women and it is extremely rare in children. We report a case of a 4 year old girl who suffered from recurrent urinary tract infection and antibiotic therapy resistance. She had low growth-rate and palpable left renal mass on examination and was confirmed by radiological findings. We performed left kidney partial resection and then histological examination showed focal xanthogranulomatous pyelonephritis. The focal form of the disease may respond to antibiotic treatment although usually an enucleation or partial resection must be performed. In conclusion xanthogranulomatous pyelonephritis should be considered in the differential diagnosis of a renal mass and recurrent urinary tract infection in childhood.

Pielonefritis xantogranulomatosa en la infancia. A propósito de un caso / Xanthogranulomatous pyelonephritis in childhood. A case report

La pielonefritis xantogranulomatosa es una rara inflamación crónica del parénquima renal. Predomina en mujeres de edad media y es extremadamente rara en niños. Presentamos el caso de una niña de 4 años de edad, con infecciones del tracto urinario de repetición y mala respuesta a tratamiento médico. La paciente tenía retraso pondo-estatural y una masa en hemiabdomen izquierdo a la exploración y en las pruebas de imagen. Se realizó heminefrectomía superior izquierda, con posterior confirmación histopatológica de pielonefritis xantogranulomatosa focal. El tratamiento más frecuente de la forma focal es la nefrectomía parcial, aunque a veces responde a tratamiento antibiótico. Como conclusión la pielonefritis xantogranulomatosa debe ser considerada dentro de un diagnóstico diferencial de un niño con un riñón aumentado de tamaño e infecciones recurrentes (AU)
