[Penile sarcoma: a rare tumor]. / Sarcoma de pene: un tumor raro y agresivo.

OBJECTIVE: We report the case of a penile tumor presenting with lung and lymph node metastasis, with fatal evolution after the absence of response to surgery and adjuvant treatment. METHODS: Male patient presenting with a penile mass appearing progressively, with metastases. RESULTS: Partial penectomy and adjuvant chemotherapy were performed, with the appearance of a rapidly growing local recurrence which led to death of the patient in a few months. The tumor was a penile sarcoma with osteosarcomatous differentiation. CONCLUSIONS: Penile sarcoma is an unfrequent tumor that has a very aggressive behavior, requiring early diagnosis and aggressive management. It has tendency to local recurrence, and when it presents with distant metastases is lethal within a few months.

[Bilateral renal lymphangiomatosis: conservative management]. / Linfangiomatosis renal bilateral: actitud conservadora.

OBJECTIVE: Lymphangiomatosis is a benign disease of difficult diagnosis. The bilateral form is very rare, being in some cases an incidental finding. METHODS: We report the case of a female patient with the incidental radiological diagnosis of bilateral lymphangiomatosis, who did not present symptoms in relation to the disease. RESULTS: After a meticulous study with ultrasound, abdominal CT scan and the MRI the diagnosis was asymptomatic bilateral lymphangiomatosis and expectant management was decided with good outcome. CONCLUSIONS: Most cases reported have been treated by nephrectomy for diagnosis, but in our case it was possible to do precise diagnosis adding the experience of the radiologist and the urologist and she had a good outcome with conservative management.

Sarcoma de pene: un tumor raro y agresivo / Penile sarcoma: a rare tumor

OBJETIVO: Presentamos el caso de un tumor de pene que debutó con metástasis pulmonares y ganglionares con evolución fatal sin respuesta a cirugía y terapia adyuvante. MÉTODOS: Varón que se presenta con masa peneana de aparición progresiva con metástasis. RESULTADOS: Se practica penectomía parcial y quimioterapia adyuvante, apareciendo recidiva local de crecimiento rápido provocando la muerte del paciente en pocos meses. El tumor resultó ser un sarcoma de pene con diferenciación osteosarcomatosa. COINCLUSIONES: El sarcoma de pene es un tumor infrecuente pero de comportamiento muy agresivo que requiere un diagnóstico precoz y una actitud agresiva en su manejo. Tiene tendencia a la recurrencia local y cuando debuta con metastasis a distancia es letal en pocos meses

Linfangiomatosis renal bilateral: actitud conservadora / Bilateral renal lymphangiomatosis: conservative management

OBJETIVO: La linfangiomatosis es una enfermedad benigna pero de difícil diagnóstico. La forma bilateral es muy rara, pudiendo tratarse en algún caso de un hallazgo casual. MÉTODOS: Presentamos el caso de una paciente diagnosticada radiológicamente de linfangiomatosis bilateral de forma casual pues no presentaba síntomas derivados esta patología. RESULTADOS: Después de un estudio minucioso con ecografía, TAC-abdominal y RNM y con el diagnóstico de linfangiomatosis bilateral asintomática, se decidió actitud expectante con buena evolución posterior. CONCLUSIONES: La mayoría de casos descritos han recurrido a la nefrectomía para su diagnóstico, pero como en nuestro caso, es posible un diagnóstico certero con la experiencia del radiólogo y urólogo y un manejo conservador con buena evolución
