[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. Six ultrasound guided needle biopsies were performed. The samples from the right lobe were reported as Gleason 6 foamy cell prostatic adenocarcinoma. RESULTS: Prostatic foamy cell carcinoma is a rare tumor, and so are its bibliographic references. Its cells lack of prominent nucleus and nucleoli. They show a plentiful and xanthomatous cytoplasm, with abundant intracytoplasmic pink secretions characteristically. It may be mistaken with low grade adenocarcinomas, and it is essential to differentiate it from the clear cell prostatic adenocarcinoma, prostatic adenosis, and even from benign prostatic hyperplasia. It usually has an intermediate grade, with a Gleason score greater than 4.

[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. We did not find any case described in a patient with tuberous sclerosis either, as the present case, being a 51-year-old female with presenting with a big abdominal mass arising from the left kidney (25 cm) and another 2 cm mass in the right kidney. CONCLUSIONS: We emphasize the extreme rarity of this tumor in the kidney. It has benign characteristics and behavior, and good prognosis, but requires surgical treatment to obtain a proper histopathologic diagnosis, based on immuno-histochemical studies.

[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. The patient died due to fungal infection after new treatment with systemic chemotherapy and bone marrow transplantation. CONCLUSIONS: It is necessary to suspect the existence of leukemic cells within the testicles in patients with this disease, mainly acute lymphoblastic leukemia, who present with acute testicular symptoms. Testicular biopsy confirms the diagnosis. Treatment is systemic, with testicular radiation to eradicate the leukemic reservoir. Despite the achievement of local disease control, this situation worsens the prognosis.

[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. METHODS/RESULTS: 61-year-old patient presenting with urethral bleeding, PSA 12 ng/cc, and an exophytic urethral mass. Histology was compatible with ductal adenocarcinoma of the cribiform type. Radical prostatectomy was carried out with good outcome at six months follow up. CONCLUSIONS: Prostatic ductal adenocarcinoma is a rare tumor, accounting for 0.2-5% of prostatic tumours. Its behaviour is variable, similar to the acinar cell type. Strikingly, there are scarce references to this tumor type; accordingly to the statistics of incidence it should have been referred more often, which would help to its study in terms of outcomes, treatment, and prognosis.

[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. CONCLUSIONS: Surgery is the definitive solution for urinary tract endometriomas. The definitive treatment of endometriosis must be done by gynecologists, by means of hormonal and surgical treatment depending on age, severity and location of the lesions, patient's wishes for future pregnancies, and tolerance to hormone therapy.
