Myxolipoma of the renal capsule: A case report

AbstractINTRODUCTIONAlthough lipomas are the most common mesenchymal tumors of the human body, primary intrarenal lipomas are quite rare. In this report we present a case of benign mesenchymal tumor with lipomatous and myxoid components.PRESENTATION OF CASEA sixty one years old male patient was admitted to our outpatient clinic for a general control since he had a right radical nephrectomy operation due to renal cell carcinoma (RCC) eight years ago and he did not have any urological control for last 3 years. However the urinary ultrasound revealed a mass lesion on left kidney and then on axial contrast-enhanced computed tomography (CT) scan, there were two masses on the left kidney. In the magnetic resonance imaging (MRI), the tumor on cortex was depicted as a homogeneous low-signal intensity on the T1-weighted pulse sequence and as a heterogeneous high-signal intensity on the T2-weighted pulse sequence. In pathological evaluation, the biopsy material of the cortical mass was a tumoral lesion containing lipomatous and mixoid areas without atypia, mitosis or necrosis which was diagnosed as myxolipoma.DISCUSSIONMyxolipoma, an uncommon type of lipoma, is a benign tumor composed mainly of fat cells with myxoid (mucus-like) components. In our case, the tumor was composed of mature adipocytes together with areas rich in mucoid substances and there were no malignant features including lipoblasts, mitosis or abundant capillary network.CONCLUSIONHerein we present a case of a fatty tumor originating from the renal capsule with the histologic diagnosis of myxolipoma. To the best of our knowledge, myxolipoma, a very rare form of lipoma, is not reported in kidney, in the literature before

COMPARISON OF HOUNSFIELD UNITS OF THE RENAL PAPILLAE IN KIDNEY STONE FORMERS AND NON STONE FORMERS

Objective: To investigate whether renal papillae of patients with nephrolithiasis are more radiodense than that of control patients and to evaluate the predictibility of urolithiasis events using papillary density differences between stone and non stone formers

An unusual cause of hematuria; primary epiploic appendagitis

INTRODUCTION: Primary epiploic appendagitis (PEA) is self limiting inflammatory disease of colonic epiploic appendices. PRESENTATION OF CASE: Herein, a 40 years old patient describing abdomino-inguinal pain with clotty hematuria having PEA was presented. At first, the patient was thought to have a primary bladder pathology, but after a meticioulus examination, he found to have PEA and managed by conservative measures. DISCUSSION: Although PEA does not require surgical intervention, it may mimic other acute abdominal disorders which can be difficult to differentiate. Appendices overlying the sigmoid colon and cecum are more prone to be affected as they are more elongated and wider in size. The patient is usually admitted due to sudden onset of abdominal pain accompanied with fever, abdominal tenderness and leucocytosis. CONCLUSION: The present case demonstrated that PEA located close to the lower urinary tract especially urinary bladder might present with urinary symptoms such as hematuria. dysuria, pollakuria and inguinal pain

Primary testicular lymphoma: Two case reports and review of the literature

Primary testicular lymphoma, is a rare testis tumor that accounts for only less than 9% of all testis tumors. In the preoperative period, it is extremely difficult to distinguish this tumor from other testis tumors. Its diagnosis is done by histological analysis. Most commonly encountered histological type is diffuse large Bcell lymphoma. Adjuvant radiotheraphy and/or chemotheraphy is given after orchiectomy. Prognosis is worse than other testis tumors. Non-metastatic tumors indicates good prognosis within one year. Ongoing research in patients with primary testicular lymphoma, are on efficacy of adjuvant theraphies and preventive and cure effect on extranodal extension to central nervous system which is the most common site for recurrency. There are conflicting results because of the small number of patient size. Here we present two cases with primary testicular lymphoma at the ages 71 and 82

The adverse influence of spina bifida occulta on the medical treatment outcome of primary monosymptomatic nocturnal enuresis

Objective: Previous reports have suggested that the incidence of spina bifida occulta (SBO) in patients with primary monosymptomatic nocturnal enuresis (PMNE) is higher than the general population. The purpose of this study was to investigate the effect of spina bifida occulta on the medical treatment outcome of PMNE. Material and Methods: Between January 2008 and December 2011, a total of 223 children (151 boys and 72 girls, aged 6-16 years; mean age: 10.1 ± 3.04 years) with PMNE were reviewed retrospectively. All of the children underwent physical examination, urine analysis, urinary tract ultrasonography and kidney ureter bladder (KUB) scout film. All patients were initially treated with a timed voiding program and were given desmopressin acetate when necessary. Results: Spina bifida occulta was detected in 75 children (33.6%). Spina bifida occulta affected L4 in 2 children, L5 in 6 children, L4-L5 in 3 children, S1 in 52 children, S2 in 7 children and S1-S2 in 2 children. Treatment was successful in 79% of the children without SBO, and in only 48% of the children with SBO. Medical treatment success rates differed significantly between the study groups. Conclusion: The presence of spina bifida occulta significantly affects the response to medical treatment in patients with PMNE. Thus, verifying spina bifida occulta status in PMNE can facilitate prognostic predictions about the response to medical treatment
