BackgroundWe present a case of Xanthogranulomatous pyelonephritis (XGPN) in a male child with renal vein thrombus extending into the inferior vena cava. This is a rare presentation. XGPN is a rare type of renal infection characterised by granulomatous inflammation with giant cells and foamy histiocytes. The peak incidence is in the sixth to seventh decade with a female predominance. XGPN is rare in children.Case presentationAn 11 year old male child presented with a history of high grade fever and chills, right flank pain and progressive pyuria for two months. He had a history of vesical calculus for which he was operated four years back. In our case, a subcapsular right nephrectomy was performed. The surgical specimens were formalin fixed and paraffin embedded. The sections were stained with routine Hematoxylin & Eosin stain. Grossly; the kidney was enlarged with adherent capsule and thickening of the perinephric tissue. The pelvicalyceal system was dilated and was filled with a cast of pus. Histological evaluation revealed diffuse necrosis of the renal parenchyma and perinephric fat. Neutrophils, plasma cells, sheets of foamy macrophages and occasional multinucleate giant cells were seen. The renal vein was partially occluded by an inflammatory thrombus with fibrin, platelets and mixed inflammatory cells. The thrombus was focally adherent to the vein wall with organization.ConclusionsThe clinical presentation and the macroscopic aspect, together with the histological pattern, the cytological characteristics addressed the diagnosis towards XGPN with a vena caval thrombus. Our case illustrates that the diagnosis of XGPN should be considered even in paediatric age group when renal vein and vena caval thrombi are present.
the result of this study show, a high frequency of ITC (20.3 %). ITC was more frequent in euthyroid patients (P value 0.029). Incidence of ITC is not significantly different between patients presenting with SNG from those with MNG (P value 0.262). Papillary carcinoma was the commonest ITC (97.4 %) and follicular variant (16/38) was found more often than micropapillary variant (3/38).
The myelodysplastic Syndromes (MDS) are a group of clonal hematopoietic stem cell diseases characterized by cytopenia(s), dysplasia in one or more of the major myeloid cell lines, ineffective hematopoiesis, and increased risk of development of acute myeloid leukemia. The classification and the diagnostic criteria have been redefined by the recent World Health Organization Classification of Tumors – International Agency for Research on Cancer for Hematopoietic and Lymphoid Tissues. The myelodysplastic syndromes are now classified into the following categories – refractory cytopenia with unilineage dysplasia, refractory anemia with ring sideroblasts, refractory cytopenia with multilineage dysplasia, refractory anemia with excess blasts, myelodysplastic syndrome associated with isolated del (5q), myelodysplastic syndrome – unclassifiable, and childhood myelodysplastic syndrome. The clinicopathologic features, morphology, differential diagnosis, immunophenotyping, cytogenetics, prognosis and predictive factors are presented in the light of recent World Health Organization Classification of Tumors – International Agency for Research on Cancer.
We present a case of basal cell adenocarcinoma (BCAC) in the tongue in a 65-year old male. This is an extremely rare presentation. BCAC generally occurs in the parotid gland and rarely involves the minor salivary glands. Few cases have been reported in literature with a variable presentation. The biopsy was formalin-fixed and paraffin-embedded. The sections were stained with routine Hematoxylin and Eosin. Immunohistochemistry was performed. Hematoxylin and eosin staining showed tumour composed of variable sized and shaped, nests and sheets of basaloid epithelial cells having hyperchromatic to vesicular nuclei. Immunohistochemistry was positive for Pancytokeratin, Epithelial membrane antigen and p53. The clinicopathological features and the cellular immunophenotype addressed the diagnosis towards BCAC of the tongue. The goal of this report is to increase awareness of this rare disease and to review and discuss the differential diagnosis and important considerations in treatment.
Context:Bombay blood group although rare is found to be more prevalent in the Western and Southern states of India, believed to be associated with consanguineous marriage.Aims:To estimate the prevalence of the Bombay blood group (Oh) in the urban population of Puducherry. To find the effect of urbanization on consanguineous marriage and to establish whether consanguinity plays a part in the prevalence of Oh group. To compare Oh group prevalence with that of other neighboring states, where population is not predominantly urban.Settings and Design:This is a descriptive study in a tertiary care hospital in Puducherry, over a period of 6 years.Materials and Methods:All blood samples showing ‘O’ group were tested with anti-H lectin. Specialized tests like Adsorption Elution Technique, inhibition assay for determination of secretor status were performed on Oh positive cases. Any history of consanguineous marriage was recorded.Statistical Analysis Used:All variables were categorical variable and percentage and proportions were calculated manually.Results:Analysis of the results of 35,497 study subjects showed that the most common group was ‘O’ group constituting 14,164 (39.90%) of subjects. Only three “Oh” that is, Bombay phenotype (0.008%) were detected. Consanguinity was observed in two cases (66.66%).Conclusions:This study shows the prevalence of Bombay blood group representing the urban population of Puducherry, to be high (0.008%) and associated with consanguineous marriage (66.66%). Thus, consanguinity is still an important risk factor present, even in an urban population in Southern India.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
