We expose a new case of prostatic blue nevus. The existing confusion in the terminology of the prostate pigmentarias injuries in reviewed literature is commented and we concluded, based on the opinion of most of authors, with a possible unification of creteries the same ones.
Intravesical prophylaxis against recurrence of urinary bladder carcinomas using mitomycin C (MMC) has proved to be and effective treatment with few side effects. Previously only two cases of lung toxicity after instillation of MMC into the urinary bladder has been described. We report a 65-year-old man in whom lung sarcoidosis occurred after intravesical administration of MMC. This association has not been reported to date. The clinical picture and the pathogenesis of this lung disease are discussed.
The genitourinary affectation by the hydatidosis, is the third in frequency after the hepatic and pulmonary affectation. The finding of an obstructive uropathy by a retrovesical hydatid cyst is uncommon, but it must be in account in high incidence zones. We present a case of this pathology, accomplishing a review of their etiopathogenic mechanisms, as well as of their arrival way, diagnostic approach and treatment.
OBJECTIVE: To describe an additional case of congenital bulbous urethra. The incidence, etiopathogenesis, symptoms, diagnosis and treatment of this condition are discussed. METHODS: A 16-year-old male consulted at the emergency services for urinary retention and a perineal lesion. Patient evaluation included ultrasound, retrograde and voiding urethrocystography. Treatment was by open surgery. RESULTS: The patient was evaluated at 3, 6 and 12 months. He remains asymptomatic and control urethrograms are normal. CONCLUSIONS: Open surgery is advocated as the treatment of choice for symptomatic diverticulum of a considerable size.
OBJECTIVE: To report an uncommon case of bilateral synchronous mixed testicular germ cell tumor. METHODS: A young male had consulted at our urological services for a unilateral enlarged testis. A testicular tumor was suspected; scrotal US was performed, testicular tumor markers were determined and complementary studies to determine tumor extension were performed. RESULTS: The US findings suggested a chronic inflammatory condition with bilateral diffuse infiltration, tuberculosis was discarded and bilateral testicular tumor was suspected, which was confirmed by bilateral intraoperative biopsy. A bilateral radical orchidectomy was performed. Adjuvant chemotherapy with cisplatin, VP-16 and bleomycin was administered after bilateral radical orchidectomy due to the attending risk factors for tumor recurrence. The patient is disease-free one year postoperatively. CONCLUSIONS: Bilateral synchronous testicular germ cell tumors are rare. Scrotal US is a simple, noninvasive and efficient diagnostic imaging method; however, it does not provide pathognomonic images that could indicate the histological nature of the tumor.
OBJECTIVE: To describe a case of Leydig cell tumor of the testis, discuss the criteria for determining its benign or malignant nature and the clinical features according to patient age and the hormone profile. METHODS/RESULTS: Scrotal US evaluation for an associated pathology incidentally detected a hypoechoic, homogeneous mass with preserved borders. Biological testicular tumor markers were determined and the suspicion of a Leydig cell tumor prompted a hormone study. The diagnosis of Leydig cell tumor was confirmed by intraoperative biopsy and radical orchidectomy was performed. CONCLUSION: In the case described, the ultrasound findings prompted the etiological diagnosis given the characteristics of the lesion. The definitive diagnosis was based on the pathological findings. Although classified as benign Leydig cell tumor, radical orchidectomy is advocated.
Presentation of three cases of bladder leiomyoma in women. All cases were characterized for the unspecific clinical presentation and a difficult pre-operative diagnosis, where ultrasound, cystoscopies, CAT and PAAF were used as complementary methods. The certainty diagnosis was only obtained after the histological study of the surgical piece. Treatment was in all three cases surgical, and the pathoanatomical diagnosis was bladder leiomyoma.
Castleman's disease is a disorder of the lymph tissue, of undetermined etiology and with preferentially mediastinal location, although other lymphatic and extra-lymphatic locations are also possible. This entry appears under two varieties: the most frequent, hyalovascular type which generally does not have associated systemic symptoms, and the plasmocellular type associated to multisystemic symptoms in up to 50% cases, such as fever, anaemia, hypergammaglobulinemia, etc. Additional examinations beyond those usually available are not enough to establish a certainty diagnosis against other types of tumours, so an histopathological study is required prior to arrive to this definite diagnosis. Surgery is the choice therapy, although sometimes a favourable response to radiotherapy, used as alternating or adjuvant therapy, can be obtained. Corticoid therapy can be an effective option when dealing with systemic symptoms. The paper submits one case of Castleman's disease of the hyalinovascular type with retroperitoneal location which forced us to establish a differential diagnosis with other disorders in that region more frequent in our specialty. Definite clinical diagnosis was not possible surgery was chosen and the entire lesion removed. As certainty diagnosis was therefore histologic and, up to this point, the patient has shown no signs or symptoms of relapsing.
OBJECTIVES: An additional case of retrocaval ureter is described, with special reference to the diagnosis and treatment of this uncommon condition. METHODS/RESULTS: We report a case of retrocaval ureter in a patient who had consulted for urological infection. Patient data and clinical history are presented and discussed. CONCLUSIONS: The clinical and pathological significance of retrocval ureter depend on the degree of urinary flow obstruction and the associated complications. CT with iv contrast medium is useful in confirming the diagnosis in most of the cases. When indicated, treatment by surgery and urinary tract maneuvers generally achieve good results.
Description of a case report of a male patient with a long standing pressure hydrocele that underwent spontaneous rupture while doing farm work although there was no previous trauma. The clinical signs were minimal scrotal discomfort, disappearance of turgescence and late ecchymosis and localized edema in penis and scrotum.
