Late recurrence from a renal cell carcinoma: solitary right maxilar mass 17 years after surgery.

OBJECTIVES: To report a new case of late renal cell carcinoma recurrence. METHODS: Renal cell carcinoma represents approximately 3% of all adult malignancies. The most frequent metastatic sites are lung (76%), regional lymph nodes (66%), bone (42%), and liver (41%), and it is the third most common infraclavicular neoplasm to metastasize to head and neck. RESULTS: 73 year-old man with a 1 week history of recurrent epistaxis. He underwent left nephrectomy 17 years before due to a renal mass of 8.5 cm in the upper pole of the left kidney. The histological diagnosis of the referred mass was clear cell carcinoma. No metastatic lesion was found at that time (Stage I, pT2N0M0). CT scan showed a mass in the right nasal cavity, invading the right ethmoidal sinus and the right orbit. Examination under general anaesthesia and biopsy was performed revealing metastasis of a renal cell carcinoma. CONCLUSIONS: The natural history of renal cell carcinoma is highly variable, metastases may present decades after the removal of the primary disease, however, only 1% of patients with renal cell carcinoma have metastases confined only to the head and neck, and solitary cervical metastatic mass is rare. Moreover, renal cell carcinoma should be considered in the differential diagnosis of any growing lesion in the head and neck.

Recidiva tardía de un carcinoma de células renales. Metástasis maxilar derecha 17 años después de la primera cirugía / Late recurrence from a renal cell carcinoma: Solitary right maxilar mass 17 years after surgery

OBJETIVOS: Presentar un nuevo caso de recidiva tardía de un carcinoma de células renales.MÉTODOS: Los carcinomas renales suponen el 3% de todos los tumores en el adulto. Los lugares más frecuentes de afectación metastático son el pulmón (76%), ganglios linfáticos regionales (66%), hueso (42%) e hígado (41%), y además, es la tercera neoplasia infraclavicular en frecuencia en metastatizar en cabeza y cuello RESULTADOS: Varón de 73 años que consulta por episodio de epistaxis de 1 semana de evolución. El paciente había sido sometido a una nefrectomía izquierda por una masa de 8,5 cm en polo superior renal 17 años antes. El informe anatomo patológico fue de carcinoma renal de células claras. No se evidenciaron metástasis en los estudios de extensión previos a la cirugía (Estadio I, pT2N0M0). En el nuevo ingreso se realizó un escaner que mostró una masa en la cavidad nasal derecha que invadía en el seno etmoidal y la órbita derecha. Se llevó a cabo una exploración bajo anestesia con toma de biopsia confirmando la histología de carcinoma renal de células claras.CONCLUSIONES: La historia natural del cáncer renal es muy variable, pudiendo aparecer metástasis décadas después de la nefrectomía inicial, si bien sólo el 1% de estos pacientes presentan metástasis confinadas solamente a la cabeza y cuello. El carcinoma de células renales debe ser considerado en el diagnóstico diferencial de cualquier masa en cabeza y cuello(AU)

[Ovarian metastasis of a primary renal cell carcinoma]. / Metástasis ovárica de carcinoma de células renales primario.

OBJECTIVE: We report one case of ovarian metastasis secondary to a renal clear cell carcinoma. METHODS/RESULTS: 52 year-old consulting for metrorrhagia with the initial diagnosis of primary ovarian carcinoma. Tumor dissemination work up tests reported a renal mass suggestive of ovarian metastasis. Surgery included hysterectomy, double annexectomy, and radical nephrectomy. Final diagnosis was renal clear cell carcinoma with ovarian metastasis. CONCLUSIONS: Metastases to the ovary pose a diagnostic problem in their interpretation, especially when they show a similar histology to the primary ovarian tumor. Due to therapeutic and prognostic implications, it is very important to differentiate if it is a primary ovarian tumor or a metastasis from a renal carcinoma.

Metástasis renal de carcinoma epidermoide de pulmón. A propósito de un caso / Renal metastasis from an squamous cell carcinoma of the lung. Case report

OBJETIVO: Presentar un nuevo caso de metástasis renal de un carcinoma epidermoide de pulmón. MÉTODOS: Varón de 60 años remitido a consultas externas de urología por hallazgo ecográfico de una masa renal en estudio por microhematuria. RESULTADOS: Los estudios de imagen evidenciaron la presencia de una tumoración sólida en polo superior que se introducía hacia el seno renal, originando un atrapamiento de la arteria renal. El TC planteó el diagnóstico diferencial entre un carcinoma de células renales, un urotelioma o un proceso metastático. CONCLUSIONES: El cáncer de pulmón puede producir metástasis en cualquier órgano, pero el riñón no es uno de los órganos de asentamiento más frecuentes, sin embargo, la existencia de dos o más metástasis extratorácicas confieren un pobre pronóstico a esta patología (AU)

OBJECTIVE: To report a new case of renal metastasis from an squamous cell carcinoma of the lung. METHODS: A 60 year old male presented to the outpatient office with an ultrasound finding of renal mass. RESULTS: Imaging test studies showed a heterogeneous mass in the upper pole of the left kidney, involving the pelvis and trapping the renal artery. CONCLUSIONS: Clinically recognised or symptomatic metastases to the kidney from pulmonary cancer have been a rare occurrence. Nevertheless, prognosis associated with lung carcinoma metastatic to the kidney is very poor, since the likelihood of a truly solitary metastasis is remote (AU)

Secondary testicular plasmocytoma.

OBJECTIVE: [corrected] To report a rare case of secondary testicular plasmocytoma in the context of a testicular mass. METHOD: We introduced a patient with plasmocytoma and a testicular infiltration of his systemic affection. RESULT: An inguinal orquiectomy was performed to treat the testicular infiltration and no recurrence of the process was seen after 6 months of follow up. CONCLUSIONS: Plasmacytoma is a plasma cell tumor that involves bone marrow or extramedullary sites. Testicular infiltration by plasma cells such as plasmacytoma happens in only 2% of cases of all plasma cell neoplasm

Objetivo: Presentar un caso raro de plasmocitoma testicular secundario en el contexto de una masa testicular. Métodos: Se trata de un paciente con un plasmocitoma y con infiltración testicular de su proceso sistémico. Resultado: Para tratarlo se realizó una orquiectomía por vía inguinal, sin presentar recidiva de su proceso sistémico tras 6 meses de seguimiento. Conclusiones: El plasmocytoma es una tumoración de células plasmáticas que puede asentar sobre la médula ósea o sobre zonas extramedulares. La infiltración testicular por células plasmáticas ocurre sólo en el 2 % de los caso de tumores de células plasmáticas (AU)
