Chyluria is the passage of chylus into urine resulting in fistulization through the lymphatic system and the urinary system. This rare condition is usually caused by filaria infestation or malformations, neoplasia or trauma. We report a case of a 18-year-old man. The patient presented milky urine which had appeared after angiography following minor leg trauma. Physical examination revealed asymmetry of the face and cutaneous dyschromia. Blood tests revealed hypogammaglobulinemia and altered CD4/CD8 ratio (0.6). Urine tests showed proteinuria (30 mg/dl), lipiduria (triglycerides 750 mg/dl) and density of 1025. Renal function was normal. Abdomen computed tomography and urography were normal. Cystoscopy revealed the presence of milky urine in the bladder and selective catheterization revealed that the origin was the right ureter alone. Ascendent pyelography did not reveal any malformation of the urinary tract; but after this the chyluria spontaneously disappeared. The patient was rehospitalized 3 months later for recurrence. Lymphography was then performed and revealed a dilated lymphatic network with minute lacunar images projecting into the right kidney. Chyluria again disappeared spontaneously and recurred sporadically over the next two years in a patient who remained in good physical condition. The etiology of chyluria in a patient without filaria infestation is problematic, particularly when the most common causes (tuberculosis, neoplasia, trauma) are excluded as in our case. The asymmetry of the face, together with cutaneous dyschromia and the presence of a subarachnoidea cyst in the right temporal region suggested our patient had multiple congenital malformations.

A 35-year-old woman was admitted to the Nephrology and Dialysis Unit of Pisa University for hypertension, hypokalaemia, renal impairment, proteinuria and hyperglycaemia. plasma renin activity (PRA) and plasma aldosterone were elevated, but Doppler ultrasound and angio-computed tomography (CT) of renal arteries were normal. Abdomen CT revealed only a left adrenal mass, and measurement of catecholamines suggested the diagnosis of pheochromocytoma. Biochemical findings suggestive of hyperparathyroidism were also detected, but a multiple endocrine disorder was excluded by genetic analysis. Pathology examination confirmed the pheochromocytoma and immunohistochemistry also showed positivity for parathyroid hormone. After surgery, disappearance of the symptoms and normalization of all haemodynamic and humoral parameters was observed. This is a rare case of pheochromocytoma responsible for secondary hyperaldosteronism, hyperparathyroidism, proteinuric renal disease and diabetes mellitus.

Tuberculosis-related chronic granulomatous tubulointerstitial nephritis (GTN) and chronic renal dysfunction as a consequence of GTN is a rarely seen clinical condition, with a few case reports in the literature. In this report, a case with end stage renal failure as an unexpected late extrapulmonary sequela of tuberculosis has been presented. A 60 years old female patient was admitted to hospital with the complaints of fever, malaise and nausea. Her history revealed that she had pulmonary tuberculosis 30 years ago and received antituberculosis therapy for nine months. The laboratory results on admission were as follows: blood urea nitrogen 90 mg/dl, serum creatinine 9 mg/dl, sodium 116 mEq/L, potassium 6.6 mEq/L, albumine 2.9 g/dl, hemoglobin, 8.4 g/dl, white blood cell count 10.800/mm3, C-reactive protein 187 mg/L and erythrocyte sedimentation rate 110 mm/hour. Urinalysis showed 8.1 g/L protein, 10-12 leukocytes, 1-2 erythrocytes, while 24-hours urinalysis yielded proteinuria with 8 ml/minutes creatinine clearance value. Urine and blood cultures of the patient revealed neither bacteria or mycobacteria. PPD skin test was negative. Acid-resistant bacilli (ARB) were not detected in sequential urine samples obtained on three consecutive days. Since sputum samples could not be obtained, diagnostic procedures for sputum were not performed. Abdomen ultrasonography yielded bilateral edema and grade II echogenity in kidneys. Computed tomography of the chest showed bilateral pulmonary nodules, chronic sequela lesions, pleural scarring and calcifications, as well as minimal interstitial infiltrate. Transthoracic lung biopsy showed chronic inflammation and fibrosis, while amyloid was negative. Renal biopsy showed GTN with central caseified necrosis and granulomas, multinuclear giant cells, tubular atrophy and interstitial fibrosis. Amyloid was negative and ARB were not detected in renal biopsy sample. Definitive diagnosis was achieved by the demonstration of Mycobacterium tuberculosis nucleic acid in kidney biopsy by polymerase chain reaction (PCR). Antituberculosis therapy was not initiated since there were no signs of active tuberculosis. The patient became clinically stable following dialysis and was discharged, however, she has been undergoing hemodialysis three times a week. The aim of this case presentation was to emphasize that renal tuberculosis should be considered in the differential diagnosis of patients with end stage renal failure, especially in countries like Turkey where tuberculosis incidence is high.
