[Non-venereal sclerosing lymphangitis of the penis. Report of two clinical cases]. / Linfangitis esclerosante no venérea del pene. Presentación de dos casos clínicos.

Nonvenereal sclerosing lymphangitis of the penis is a rare condition that preferably affects men aged between 20 and 40 years, and it is appeared like a hard cord or a nodular lesion in the sulcus coronarius penis. It is believed that it has origin in lymph vessels of the penis. Usually it is resolved in a self-limited way, so the initial treatment is conservative. We report two cases, and some etiopathogenic, diagnosis and therapeutic aspects are discussed.

[Primary signet ring cell adenocarcinoma of the bladder. Report of a case]. / Adenocarcinoma vesical primario de células en anillo de sello. Aportación de un caso clínico.

Primary adenocarcinoma of ring cells's bladder is a neoplasm very uncommon and aggressive. Its clinic aspects and diagnosis don't differ too much from the rest of the bladder's neoplasm. It's important the differentiation from a possible primary extravesical origin. Radical surgery is the only treatment with sensitive answer, and the prognosis in awful. We report a case.

[Fracture of the penis. Review of the literature and presentation of 2 cases]. / Fractura de pene. Revisión de la literatura y presentación de dos casos.

We report two cases of a very uncommon pathology as is the rupture of the corpus cavernosum of the penis, undergoing early surgical management with good results. We also review the diagnostic, clinical and etiological aspects, and the most appropriate treatment.

[Bladder leiomyoma: review of the literature and report of 3 clinical cases]. / Leiomioma vesical: revisión de la literatura y presentación de tres casos clínicos.

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.

[Leydig cell tumor]. / Tumor de células de Leydig.

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.

[Castleman's disease, plasma-cellular variety: unusual finding in our specialty]. / Enfermedad de Castleman, variedad plasmo-cellular: un raro hallazgo en nuestra especialidad.

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.

[Metastatic hypernephroma of the stomach]. / Hipernefroma metastásico de estómago.

We report a case of renal cell adenocarcinoma (T2-G3) metastatic to the stomach in a patient who underwent a left radical nephrectomy and presented hematemesis and melena two weeks postoperatively. We were prompted to report this case because metastasis to the stomach is rare and the literature is scant. Despite treatment by radical surgery, the short disease-free period following nephrectomy, the high histological grade (G3) and the aggressive nature of the tumor have resulted in a short survival.

[Renal adenocarcinoma in the isthmus of a horseshoe kidney]. / Adenocarcinoma renal en el istmo de un riñón en herradura.

A case of renal adenocarcinoma localized to the isthmus of a horseshoe kidney is described. We underscore the importance of complementary US and/or CT to urography to study the acquired pathologies of the horseshoe kidney because the pyelocaliceal distribution of these kidneys may not facilitate correct identification of certain space occupying lesions. The angiographic study is considered essential for planning surgery for this type of lesion.

[Leydig cell tumor]. / Tumor de células de Leydig.

We report on a 44-year-old patient with Leydig cell tumor of the testis that had been incidentally detected following orchidectomy for a tumor. The clinical, hormonal and histological criteria currently used to distinguish the malignant from the benign form of this tumor and the different therapeutical alternatives are discussed.

[Non-venereal sclerosing lymphangitis of the penis]. / Linfangitis esclerosante no venérea del pene.

Non-venereal sclerosing lymphangitis of the penis is a rare condition that affects the distal lymphatics of this organ. It has been reported to be frequently associated with trauma to this area and, although it has a minimum inflammatory component, its etiology is unknown. A serpinginous nodular lesion in the sulcus coronarius penis may be observed by the patient. Because it is generally self-limiting, treatment is initially conservative and surgical excision is performed only if symptomatic lesions persist. The present study reports an additional case. The literature is reviewed and the possible etiopathogenic mechanisms and therapeutic alternatives are discussed.

[Sarcoma of the bladder. Report of 2 cases]. / Sarcomas de vejiga. A propósito de dos observaciones.

Discussion of a retrospective study in our unit of two cases of vesical tumours of mesenchymal origin, in adult patients and with different maturation behaviour. The first patient started with haematuria and after an extensive follow-up period is now free from the disease. The second patient was an accidental finding causing death in the course of the immediate postoperative.

[Renal arteriovenous fistula, up-date and presentation of a new case]. / Fístulas arteriovenosas renales, actualizacíon y presentación de un nuevo caso.

Renal arteriovenous fistulae (AVF) conform a pathology the urologist is not used to see. The basic purpose of this paper is to collect and update the current knowledge of this renal-vascular disorder, quite frequently forgotten when establishing the likely causes of haematuria. The paper describes the etiology of renal AVF and their generation mechanisms, as well as clinical presentations they can have. A most appropriate diagnostic method is still selective renal arteriography, which usually evidences the anomaly through indirect arteriographic signs. However, when the lesion is small it can be difficult to detect it. Finally, a discussion of therapeutical possibilities, both conservative and radical, and a case recently treated in out unit are presented.

[Bladder metastasis of a renal cell carcinoma]. / Metástasis vesical de un carcinoma de células renales.

We report on a patient with renal adenocarcinoma that subsequently metastasized to the bladder. Although involvement of any organ in this area can lead to secondary invasion of the bladder wall, hematuria presenting in a patient previously submitted to nephrectomy due to hypernephroma should prompt us to strongly suspect tumor spread to the bladder. The forms of metastatic spread and treatment are discussed. Good results were achieved in our patient who, with a follow-up of 1.5 years, has had no tumor recurrence.

[Pleomorphic bladder rhabdomyosarcoma in an adult male. Apropos of a case]. / Rabdomiosarcoma pleomórfico vesical en un varón adulto. A propósito de un caso.

We report on a 45-year-old male patient with a mesodermal tumor localized in the striated muscle of the bladder wall. The histopathologic analysis revealed a stage I pleomorphic tumor. The clinical and histologic features of this uncommon tumor type are described. Treatment by partial surgery and adjuvant chemo- and radiotherapy (CMT + XRT) have achieved good results. The patient is asymptomatic 44 months thereafter.

[Sarcomatoid carcinoma of the kidney: presentation of a case]. / Carcinoma renal sarcomatoide: presentación de un caso.

We describe a case of sarcomatoid variant, renal adenocarcinoma in a 69-year-old woman, whose death took place four months after the diagnosis was effected. We underline the form of clinical and radiological presentation, its low frequency, poor prognosis and difficult anatomopathological diagnosis.

[Pieloureteral duplication with complicated orthotopic ureterocele]. / Duplicidad pieloureteral con ureterocele ortotópico complicado.

A ureterocele in an adult patient is described. The characteristic clinical features of this condition associated with pyeloureteral duplicity and several secondary disorders make it an unusual case. The clinical features and treatment are described. The etiologic aspects are discussed, highlighting the acquired factors, as well as the diagnostic and therapeutic procedures.

[A cyst of the seminal vesicle]. / Quiste de la vesícula seminal.

We present a case of seminal vesicle cyst in a fertile patient. Sporadically appearing hemospermia was the only symptom. We single out thiss pathology and the clinical procedure of this case as being uncommon. Transabdominal echography revealed the presence of the cyst. The T.A.C. did not offer further data. The Deferento vesiculograph was demonstrative. We consider other diagnostic methods and a differential diagnosis is made with other deep pelvis cysts.
