[Inflammatory prostatic pseudotumor (fibromyxoid pseudosarcomatous tumor)]. / Pseudotumor inflamatorio de prostata (tumor fibromixoide pseudosarcomatoso).

OBJECTIVES: To report one case of an exceptional benign prostatic pathology and its differential diagnosis with malignant tumors. METHODS: 67-year-old male who suffers an acute urinary retention requiring bladder catheterization and subsequent negative catheter removal tests. Digital rectal examination showed a small prostate, adenomatous, without nodules. PSA was 1.01 ng/ml. The patient underwent transurethral resection of the prostate because of the persistence of urinary retention. RESULTS: Pathologic study reported a hypercellular stroma, with a perivascularly distributed inflammatory infiltrate and myxoid stromal background with slightly atypical fusiform cells. Immunohistochemical studies showed positive staining of fusiform cells for vimentin and histiocytes in the lesion for CD68, and negative staining for cytokeratin. The final diagnosis was prostatic inflammatory pseudotumor. CONCLUSIONS: In spite of being an unfrequent presentation it is important to take this benign lesion under consideration to avoid unnecessary aggressive radical complementary treatments.

[Assessment of the Gleason score in biopsies and specimens of radical prostatectomy]. / Valoración del grado de Gleason en biopsias y piezas de prostatectomía radical.

OBJECTIVES: To evaluate the similarity between Gleason grade on prostate biopsies and their final result after radical prostatectomy. METHODS: We retrospectively review the medical records of 129 patients who underwent radical prostatectomy. Mean PSA value was 10.7 ng/ml. The relationships between pathological reports of biopsies and radical prostatectomy specimens, and other variables such as PSA were established. RESULTS: Globally, 72 cases (55.8%) were in the same risk group by grade on biopsy and surgical specimen. Biopsy result was understaged in 48 cases (37.2%) and overstaged in 9 cases (7%). We found biopsy understaging in 42 cases (60%) in the low grade group, 6 cases (10.9%) in the intermediate grade group, and 50% in the high grade group, although in this latter the number of cases was very low. CONCLUSIONS: Overall biopsy understaging was 37.2%, being much more evident in low grade tumors (60%). It seems that understaging was greater when PSA > 10 ng/ml, although differences were not significant.

[Pneumopyocystitis in a patient with adult polycystic kidney disease]. / Pioneumoquistes en paciente con enfermedad poliquística del adulto.

OBJECTIVES: We present a case of adult polycystic kidney disease, also known as autosomal dominant polycystic kidney, complicated by infection of the cysts and the formation of gas within them. METHODS/RESULTS: A 59 year old patient diagnosed of adult polycystic kidney disease with chronic renal failure on treatment with haemodialysis, who presented sepsis secondary to infection of the renal cysts. The CT scan demonstrated the presence of gas within the cysts and the microbiology revealed E. coli in one of them. Urgent nephrectomy was performed. A histological specimen of the excised organ is also presented. CONCLUSIONS: Infection of one or more cysts in adult polycystic kidney disease is a rare and serious complication which may require immediate nephrectomy, particularly if gas appears within the cysts.

[Clinical presentation of testicular germinal cancer]. / Presentación clínica del cáncer germinal de testículo.

OBJECTIVE: To review the clinical features in our series of patients of germ-cell testicular cancer. METHODS: The charts of 73 patients with diagnosis of germ-cell testicular tumours were reviewed. Age, history of cryptorchism, time to diagnosis, main symptoms, and serum markers values (alpha- fetoprotein and beta-HCG) were analysed. All cases underwent orchiectomy and extension study with abdominal CT-scan and either chest X-ray or Thoracic CT-scan. We follow the AJCC-UICC 1997 stage classification. Histological cell line, size, and clinical stage at presentation (local, regional and distance) have been analysed also. RESULTS: Among 73 germ-cell testicular tumours 34 were seminomas (46.6%) and 39 were non-seminomatous (54.4%). Clinically, 58.9% of the patients had localised stage I tumours. On presentation 85.7% seminomas were stage I compared to 35.9% non-seminomatous tumours. The remaining tumours were diagnosed in advanced phases (stages II and III). Inguinal orchiectomy was performed in all patients except 5 in whom tumours were incidentally diagnosed (atrophic testis orchiectomy, hydrocoelectomy, trauma) and needed a second operation including ipsilateral scrotal excision. When size, cell line and primary tumour T category were reviewed we found that 32.3% seminomas and 20.5% non seminomas were smaller than 4 cm. 50% seminomas and 49.7% non seminomas were pT1; 41.2% seminomas and 28.2 non seminomas were pT2; finally 8.8% seminomas were pT3 compared to 23.1% non seminomas. Vascular infiltration, also evaluated in this chapter, was present in 38.2% seminomas compared to 38.5% non seminomas. Elements of embryonal carcinoma were found in 37 non seminomatous tumours, either isolated (14) or associated with other components. Teratoma appeared in 18 non seminomatous tumours, 16 of them associated to embryonal carcinoma alone or together with other components. Elements of choriocarcinoma and endodermal sinus were evident in 5 and 4 cases respectively, always associated with other elements. CONCLUSIONS: Seminomas clinical presentation substantially differs from that of non seminomatous testicular tumours in age, clinical features, stage and histological aggressiveness.

[Urologic treatment of testicular germ cell cancer]. / Tratamiento urológico del cáncer germinal de testículo.

OBJECTIVE: To review the treatment of testicular germ-cell cancer in our series. METHODS: 73 cases with the diagnosis of germ-cell testicular tumours were reviewed. All cases underwent orchiectomy and extension study with abdominal CT-scan and either chest X-ray or Thoracic CT-scan. We reviewed the treatment options employed in our series, analysing different currently recognised risk factors. RESULTS: 34 out of 73 testicular germ-cell tumours were seminomas (46.6%) and 39 non seminomas (54.4%). Clinically 58.9% of the patients had localised, stage I tumours. 85.7% seminomas were stage I at presentation compared to 35.9% (14) non seminomatous tumours. The remainder tumours presented in advanced phases (stages II & III). Inguinal orchiectomy was performed in all cases except 5 patients in whom tumours were incidentally diagnosed (atrophic testis orchiectomy, hydrocelectomy, trauma) and underwent ipsilateral scrotal excision in a second time. Lymphadenectomy was initially performed in 3 patients with non seminomatous tumours. Radiotherapy was used in 23 cases of seminoma (67.6%), although this percentage has been progressively reduced in recent years. 30 patients received chemotherapy after orchiectomy: 3 metastatic seminomas (stage II) (8.8% of seminomas treated with chemotherapy) and 27 non seminomatous tumours (69.2% of them). All metastatic tumours are among the last (25) (Stages II & III) and 2 stage I non seminomatous tumours. All seminomas achieved complete response without later relapse after a median follow-up of 50 months (12-145 months). Median follow-up for non seminomatous tumours was 57 months (1-288 months). 13 non seminomas had relapses (33.3%). Relapses appeared in the retroperitoneum in 11 cases (84.6%), 2 of them concurrent with pulmonary relapse; 1 patient had liver relapse, one lung and another in bone. Median time to relapse was 4 months (2-102). 8 patients died and 2 were lost for follow-up. CONCLUSIONS: Testicular germ-cell cancer needs a well established multidisciplinary approach, in which the role of the urologist is fundamental. Orchiectomy is the primary treatment and allows determination of the dissemination risk. Radiotherapy is very effective for localised seminomas with poor prognostic factors, and for non seminomas 2 cycles of chemotherapy seem to be an effective approach, as well as of little toxicity. We must know and apply optimised programs for observation of these tumours (stage I), and also use follow-up protocols after chemotherapy or radiotherapy. Some cases need complex surgery for residual masses resection or post chemotherapy salvage surgery in disseminated tumours (Stages II & III). Sterility treatment protocols are applied to preserve fertility.

[Fulminant hepatic insufficiency caused by diffuse intrasinusoidal liver metastases in a patient with transitional-cell carcinoma of the bladder]. / Insuficiencia hepática fulminante por metástasis hepática intrasinusoidal difusa en un paciente con carcinoma transicional de vejiga.

OBJECTIVE: To present a case of transitional cell carcinoma of the bladder with diffuse intrasinusoidal metastases to the liver that presented as fulminant hepatic failure. METHODS/RESULTS: A 65-year-old patient who presented at the emergency department of this hospital with fever and pain in the right hypochondrium and flank is described. Three months previously the patient had undergone operation in our department for a recurrence of a tumor affecting the bladder and urethra (Tis of the bladder and T1 GII of the prostatic urethra). The blood tests on admission were practically normal but showed alterations from the twelfth day onwards, suggesting acute liver failure in the differential diagnosis; the patient died 21 days later. The ultrasound and CT scans showed hepatomegaly with multiple heterogeneous areas which were not visible three months earlier and with no space-occupying lesions. At autopsy, the liver was found to be enlarged, with no macroscopic metastatic nodules. Microscopic examination revealed massive tumoral infiltration of the hepatic sinusoids with diffuse replacement of the hepatocytes. CONCLUSIONS: Secondary, metastatic liver cancer usually presents as multiple nodular lesions and only vary on very rare occasions as a diffuse infiltration leading to acute hepatic failure. This case provides the first description of the autopsy findings in a bladder transitional cell carcinoma with diffuse intrasinusoidal metastases to the liver.
