[Non germinal cell testicular tumors].

Objectives: We report a review of all patients with testicular tumors undergoing surgery in our Hospital over a 13 year period. There were 151 cases, 50 of them were reported as non germ cell tumors (33%).

Methods/results: 42% of them were haematopoietic tumors, lymphomas and leukemias.

[Paratesticular leiomyosarcoma. Review and update].

Objectives: To present one case of paratesticular leiomyosarcoma, a rare tumor which has been reported in 5 cases only in our country. To review the management of this type of tumor.

Methods: A 73-year-old male presenting with a 4 cm mass adjacent to the right testicle underwent excision of the mass, spermatic cord and testicle through an inguinal approach.

[Adrenal spindle cell angiosarcoma. Report one case].

Objectives: To report a new case of spindle cell angiosarcoma of the adrenal gland.

Methods: We reviewed 22 cases previously published of this rare entity, analyzing at the same time both clinical and pathologic findings of this infrequent sarcoma of urological localization. The epithelioid variety is the most common, which makes our spindle cell type case rarer, if possible.

[Prostatic ductal carcinoma].

Objectives: We presented one case of prostatic adenocarcinoma of ductal origin, known as endometrial adenocarcinoma before. The first case was published in 1967 by Mellicow. Since then we could only recover 8 cases by spanish authors.

[Urachal cyst. Current status].

Objectives: We report one case of urachus diverticulum. It is very rare in adults so that the level of diagnostic suspicion is low.

Methods: 50-year-old male without history of urologic diseases who presented with recurrent urinary tract infections over a two-year period.

[Testicular leukemic infiltration].

Objectives: To remind that despite its low incidence, leukemic relapse in the testicles worsens the prognosis of this haematopoietic neoplasia.

Methods/results: We report the case of a 20-year-old male suffering from acute lymphoblastic leukemia in complete remission after induction and maintenance treatment, who suffered a leukemic relapse in both testicles. Diagnosis was made by ultrasound and confirmed after bilateral testicular biopsies.

[Bilateral renal solitary fibrous tumor].

Objectives: We report the first case of bilateral renal solitary fibrous tumor diagnosed in a patient suffering from tuberous sclerosis.

Methods: From the bibliographic review, only 15 cases of solitary fibrous tumor have been described in the kidney. We did not find any case of simultaneous bilateral involvement.

[Foamy carcinoma of the prostate].

Objectives: We report the first case of prostatic foamy gland carcinoma in the Spanish literature.

Methods: Case of a 69-year-old male who consulted for PSA elevation up to 101 ng/ml. Transrectal ultrasound showed a heterogeneous gland with a hipoechogenic area in the right lobe and possible capsular disruption.

[Urinary endometrioma].

Objectives: To analyze the series of cases of endometriosis with urologic involvement reported in our country.

Methods/results: We found a total of 26 cases of endometriosis including our case, 15 affected bladder and 11 ureter. Independently of ureteral or bladder location, the treatment performed varied, from transurethral resection and laser to cystectomy in cases involving bladder, from segmental ureterectomy with ureteral reimplantation to nephrectomy in ureteral cases.

[Hyperdense renal cyst].

Objective: We update the diagnostic criteria for renal cystic masses, emphasising in the clinical entity known as hyperdense renal cyst.

Methods: We report the case of a male patient who presented with an atypical left renal cyst. Radiological examinations (US and CT) were performed.
