[Reiter's syndrome and urinary infection in a case of AIDS].

Herein we describe a case of Reiter's syndrome coexisting with HIV infection in a female parenteral drug addict who was also predisposed to multiple genitourinary involvement. In our view. the manifestation of additional autoimmune states could herald the worsening of the prognosis of HIV infection and the nephrological and urological course of these patients.

Identification by molecular diagnosis of mosaic Turner's syndrome in an obligate carrier female for fragile X syndrome.

A case of mosaic Turner's syndrome with a 45,X/46,XX/47,XXX karyotype, who was also a fragile X obligate carrier as the mother of an affected boy, was identified by molecular diagnosis. Complete haplotyping and direct DNA analysis showed that the X chromosome in all metaphases was the normal X. At the age of 57, she is mentally normal.

[Primary bladder carcinoma on diverticulum. Clinico-pathologic study of 5 cases].

This paper reviews our experience with the vesical cancer which develops on the diverticulum, a situation occurring in 1.5% of all vesical tumours in our setting. The condition's clinical features (diagnostic and therapeutic), usually detected in advanced stages, are emphasized.

[Bladder carcinoma: I. Epidemiologic considerations in the Basque country].

Review of several facts of epidemiological nature, from a study on bladder urothelial carcinoma cases detected over the period 1983-1990 in our centre, a reference hospital serving the Bilbao area. Certain data recently published by the Euskadi Cancer Register allowed us to establish some considerations related to the presence of this entity in our setting. Its incidence nears the highest rates in industrial countries.

[Stenosis of the pyeloureteral junction and contralateral renal carcinoma].

We report a case of advanced ureteropelvic junction obstruction associated with contralateral renal carcinoma in a 39-year-old male patient who consulted for frequent episodes of renal colic and gross asymptomatic hematuria. The results of the renal function tests and the radiological and isotope work up indicated a two-stage surgical procedure of pyeloplasty and contralateral partial nephrectomy. At 6 years follow up the patient is tumor free and renal function is preserved.

[Ultrastructural study of the stromal component in urethral caruncle].

The stromal component of the urethral caruncle (UC) comprises a mixture of inflammatory, vascular, and fibrotic phenomena. Although mastocytes are cell elements known to appear in relation with chronic inflammation, there is no data in the literature explaining their significance in UCs or their ultrastructure relation with fibroblasts. We postulate that this special form of intercellular attachment could play a role in this condition's pathogenesis.

Cavitation of lung metastases from bladder cancer. Report of two cases.

We describe 2 cases of cavitary lung metastasis from bladder cancer and retrospectively analyze the frequency of such an event in our environment. Although rare, this finding is not exceptional and should be taken into account when clinicians and oncologists face the differential diagnosis of pulmonary cavitation. Moreover, a cavitary pulmonary nodule may also be the presenting sign of bladder cancer.

[Neurogenic bladder and recurrent emphysematous cystitis].

A case of recurrent emphysematous cystitis in a 44-year-old male diabetic is described. Treatment of the first episode had been effective and demonstrable radiologically. A recurrent episode of cystitis disclosed a neurogenic bladder, which had not been detected previously.

[Adrenal pseudocyst: clinicopathologic study of a case].

Herein we describe a case of a hemorrhagic adrenal pseudocyst that had been initially suspected as being a renal adenocarcinoma. The intraoperative anatomopathological study of the specimen permitted performing conservative surgery. The diagnosis and pathogenesis of this uncommon disease entity are discussed.

[Carcinoma of the prostate metastasized to mandible simulating primary parotid tumor].

We report a case of prostate carcinoma metastatic to the mandible that had been initially suspected as being a primary carcinoma of the parotid with lymph node metastasis. The present case underscores the diverse forms of manifestation of prostate carcinoma.

Urologic malignancies and progressive systemic sclerosis.

We present two cases of urologic malignancies, transitional cell carcinoma of the bladder and renal cell carcinoma respectively, closely associated to progressive systemic sclerosis. The relationship between such neoplasms and immune disorders is thereof reviewed. Cancer may develop in a context of diminished immunological surveillance.

[Angioma of the glans, report of 2 cases].

We present two cases of angioma of the glans penis and we reviewed this disease entity from a clinical and therapeutic points of view, classically understood as a proliferative process of a malformative nature. However, both cases that are described can be interpreted as true vascular tumors of a benign nature.

[Benign esophagobronchial fistula in an adult].

The case of a senile dementia patient 86 year old, and a supposed clinical history of swallowing a foreign body is presented. After a clinical study (esophagogram, flexible and rigid esophagoscopy and bronchoscopy) and finally the autopsy of the patient, we found and idiopathic esophago-bronchial fistula.

[Acute focal bacterial nephritis in a case of AIDS].

Presentation of one case of bacterial acute focal nephritis (acute lobe nephrosis) in a parenterally drug-abuser, HIV-infected male. From the clinical point of view, the picture was interpreted as acute hepatitis, and the lesion was detected by ultrasound techniques. A right side location, relative lack of urological symptoms and coexistence of a chronic liver disease contributed to the diagnostic error.

[Focal urinary Salmonella infection].

A case of focal Salmonella sp. urinary infection in an elderly diabetic patient is described herein. The therapeutic approach in this uncommon type of infection is discussed.

[Sexually transmitted recurrent urinary infection of the male].

We describe a case of recurrent urinary tract infection in a male patient that had been repeatedly associated with sporadic sexual intercourse with his partner. The timing of the episodes and the bacteriological findings indicate this to be another uncommon case of urinary tract infection sexually transmitted by the female to the male.

[Renal carcinoma and non-Hodgkin's lymphoma. A clinical report].

Presentation of one case of a 61-year old male with a non-Hodgkin lymphoma, where a renal cell adenocarcinoma was unexpectedly discovered during and extension study. Review of the pathogenic significance of such association in the light of the various explicative hypothesis of this concurrence.

[Chronic granulomatous disease and pulmonary nocardiosis].

A 19-years-old male was admitted for left bilobar pneumonia. All microbiologic studies in blood and in several samples obtained by bronchoscopy were negative. The patient worsened progressively despite antibiotherapy of a wide spectrum.

Intrathoracic kidney and vertebral fusion: a model of combined misdevelopment.

We report a case of right intrathoracic kidney associated with a complex somite malformation that comprised vertebral fusion and right intrathoracic supernumerary ribs. The interpretation of this association as a disease model of nature allows us to propose a unifying hypothesis on the pathogenesis of this form of renal dystopia.

[Double renal tumor: histogenetic implications].

Presentation of a new case of synchronic concurrence of renal adenocarcinoma and papillar carcinoma of renal pelvis on the same kidney. The origin of this double malignant renal tumour remains unknown, although several hypothesis have been raised. We believe that coexistence of both tumours is more than casual and we would underscore the morphogenetic interpretation of such coincidence.

Hibernoma. A case report.

The clinicopathologic features of a hibernoma occurring in a 26 year-old female are reported. The tumor was located in the interscapular region and eventually became painful. Surgical excision was performed and to date, no recurrences have been detected.

Squamous cell carcinoma of the male urethra mimicking a paravertebral abscess.

In the context of a misleading diagnosis of paraurethral abscess, we report a case of unrecognized metastatic squamous cell carcinoma of the male urethra that mimicked a picture of paravertebral abscess with accompanying massive caval vein thrombosis. Fine needle aspiration cytology of both paravertebral abscess and urethral nodule allowed the diagnosis. This report calls the attention of clinicians to think of a malignant process in case of a paravertebral abscess.

[Urologic aspects of Hippel-Lindau disease].

We report on a patient with von Hippel-Lindau disease with special reference to the urological features. Several members of the patient's family had also presented this hereditary disease. Careful follow-up of these patients permits early diagnosis of some of the characteristic tumors.
