[Unusual presentation of metastasis of prostate carcinoma as a mediastinal mass: A case report and a brief review of the literature.] / Presentación inusual de metástasis de carcinoma prostático como masa mediastínica: descripción de un caso y breve revisión de la literatura.

OBJECTIVE: To assess the metastasic prostatecancer in the differenctial diagnosis of mediastinal masses. METHODS: To report a case. RESULTS: We present the case of a 78-year-old male patientwith a diagnosis of prostate cancer with a mediastinalmass compatible with prostate metastasis. CONCLUSION: Mediastinum is a very rare site for prostatecancer metastasis, but it must be considered in thedifferential diagnosis of mediastinal masses. Treatment isthe usual for metastatic prostate cancer.

OBJETIVO: Considerar el cáncer de próstatametastásico en el diagnóstico diferencial de masas mediastínicas. MÉTODOS: Presentación de un caso clínico. RESULTADOS: Se presenta el caso de un paciente varónde 78 años con diagnóstico de cáncer de próstata en elque se objetiva una masa mediastínica compatible conmetástasis prostática. CONCLUSIÓN: El mediastino es un lugar muy infrecuentede metástasis de cáncer de próstata, pero hay que considerarloen el diagnóstico diferencial de masas mediastínicas.El tratamiento es el estándar del cáncer de próstatametastásico.

[IgG4-Related Retroperitoneal fibrosis]. / FIBROSIS RETROPERITONEAL RELACIONADA IgG4.

OBJECTIVE: To report two new cases of IgG4-related retroperitoneal fibrosis, a recently described pathology. METHODS: We analyze two cases diagnosed in our center and performed a literature review. RESULT: IgG4 related disease is a recently described entity that includes previously not related pathologies. The clinical manifestations are highly variable and its presentation is usually subacute. The treatment of choice is glucocorticoids. In our first case the outcome was favorable with corticosteroids and azathioprine. However, the second case required surgery on 2 occasions with radical nephrectomy. The diagnosis of the latter was made nine years after the onset of symptoms when the biopsy was reviewed; at that moment immunosuppressive therapy was not started. CONCLUSIONS: It is very important to know and diagnose this disease because of the good response to treatment that prevents complications.
