    Giant bladder stone in children: case report
    (Int Scientific Literature, Inc, 2008) Aktoz, Tevfi K.; Kaplan, Mustafa; Atakan, Irfan H.; Inci, Osman
    Background: Pediatric urolithiasis is an endemic disease in certain parts of the world, namely Turkey and Far East. Metabolic and environmental factors, in addition to urogenital abnormalities, should be evaluated thoroughly each patient. The aims of management should be complete clearance of stones, treatment of urinary tract infections, preservation of renal function and prevention of stone recurrence. The giant bladder stone is not very common and it is usually associated with nutritional factors. Case Report: A 3 year-old boy was admitted to our clinic with a 2-year history of recurrent urinary tract infections and urinary complaints like intermittent and painful voiding with terminal hematuria and sharp lower abdominal pain. On physical examination, the weight and height were 10 kg (below the 3rd percentile), and 85 cm (below the 3rd percentile), respectively. Direct urinary system X-ray study and intravenous urography (IVU) showed a giant bladder stone. In this case, we think that giant bladder stone is associated with nutritional factors and we were unable to find an underlying metabolic abnormality. Open surgery was performed to this patient. The bladder stone was 3.1 x 2.0 x 1.7 cm in diameter. Biochemical analysis showed that it was calcium oxalate stone. Conclusions: Treatment of pediatric urolithiasis requires a metabolic and environmental evaluation of all patients. Obstructive pathologies have to be corrected and metabolic abnormalities should be treated. Also nutritional factors related with bladder stones must be considered. Open surgery remains the main treatment of giant bladder stones in children.

    Parotid gland metastasis from renal cell carcinoma: An unusual site for metastasis
    (Int Scientific Literature, Inc, 2008) Kaplan, Mustafa; Caloglu, Murat; Caloglu, Vuslat Y.; Aktoz, Tevfi K.; Usta, Ufuk; Karagol, Hakan; Inci, Osman
    Background: Renal cell carcinoma accounts for more than 90% of malignant kidney tumors and the common sites for metastases include lung, liver, bone, brain and skin. Metastasis to the parotid gland is considered extremely rare. The most common lesions to metastasize to the parotid gland are skin, breast, lung, and thyroid cancers. Case Report: We report a case of solitary parotid metastasis from renal cell carcinoma in a 68-year-old man. Patient was referred to the clinic with a complaint of painless right preauricular mass which had been gradually increasing in size for a year. An approximately 20 cm left sided mass was appreciated on examination of the patient's abdomen. Computed tomography (CT) scan of craniocervical region demonstrated a parotid mass measuring 8x10x9 cm with invasion of the pterygoid muscles. A subsequent abdominal CT revealed a left renal lesion measuring 13x18 cm. Since the parotid gland was assumed unresectable, the patient elected to undergo a left radical nephrectomy. Moreover the sections of the right parotid mass showed similar architecture and histomorphology to the renal tumor. Conclusions: The differential diagnosis, histochemical and immunohistochemical features, and treatment of this lesion are discussed. It seems that the initial diagnosis with parotid metastasis, the larger the size of both the primary and metastatic tumor, and immunohistopathological features of the tumor, appear to have led to the poor prognosis in the present case. Although parotid masses resulting from RCC metastasis are rare, one should be aware of the possibility when a clear cell neoplasm is disclosed in the parotid specimen.
