MiT family translocation-associated renal cell carcinoma: A report of two cases in children.

Renal cell carcinoma is uncommon in children and must be distinguished from the more common Wilms' tumor. Here, we present two cases of renal cell carcinoma in children both of whom presented with hematuria. Accurate diagnosis is essential in order to differentiate it from epithelial predominant Wilms' tumor which has vastly different prognosis and treatment.

Heavy chain deposition disease in a case of clear cell renal cell carcinoma- A jack in the box.

Renal cell carcinoma (RCC) is the most common subtype of adult renal tumors, and its detection rate in the early stages has been increased in the dawn of advanced imaging modalities. Nephrectomy is the mainstay of treatment; determination of tumor category and staging is the primary concern of oncopathologists. Non-neoplastic renal parenchyma is overlooked majority of times and thus misses the opportunity to detect concomitant medical renal diseases which also predict the renal outcome in the postoperative era.

Utility of serum anti-phospholipase A2 receptor antibody as a biomarker in membranous nephropathy: An experience from a tertiary care center of Eastern India.

Background: Membranous nephropathy (MN) is a pattern of glomerular injury. Exact categorization into primary membranous nephropathy (PMN) or secondary membranous nephropathy (SMN) is essential for treatment. An endogenous podocyte antigen, M-type phospholipase A2 receptor (PLA2R) has been discovered to be involved in the pathogenesis of PMN.

Role of light and immunofluorescence microscopy to differentiate primary and secondary membranous nephropathy.

Context: Membranous nephropathy (MN) causes nephrotic syndrome, mostly primary but may be associated with SLE, infections, cancer, or drug.

Aims: To estimate clinical, serological, light microscopic, and direct immunofluorescence (DIF) findings to differentiate primary and secondary MN.

Settings And Design: Prospective, cross-sectional, single-center study in a tertiary care hospital.

Clinicopathological Spectrum of Henoch-Schönlein Purpura Vasculitis: An Experience from a Tertiary Care Center.

Henoch-Schönlein purpura (HSP) is a small vessel vasculitis with multiorgan involvement. Renal involvement is the key factor predicting morbidity. We have aimed to analyze the clinicopathological spectrum of HSP vasculitis and HSP nephritis to assess the risk factors associated with kidney involvement.

Composite phaeochromocytoma with malignant peripheral nerve sheath tumour: A case report with summary of prior published cases.

Composite phaeochromocytomas (CP) are extremely uncommon adrenal medullary tumours where phaeochromocytoma coexists with another adrenal medullary tumour also of neural crest origin. CP includes combination of phaeochromocytoma along with a component of neuroblastoma, ganglioneuroblastoma, ganglioneuroma, benign nerve sheath tumour or a malignant peripheral nerve sheath tumour (MPNST). Here we describe the morphological and immunohistochemical details of a case of CP with MPNST in a 30 years old lady, without history of neurofibromatosis.

A tale of tripartite: An experience from a tertiary care center of Eastern India.

Background: Crescentic glomerulonephritis (Cr GN) is pattern of glomerular injury resulting from wide range of diseases sharing a common pathogenesis.

Objectives: The objective of our study was to analyze the clinicopathological spectrum and outcome of Cr GN with special reference to its immunopathological subtypes using a panel of immunofluorescence stains.

Materials And Methods: Native renal biopsies with crescentic pattern of injury were included.

Diagnostic utility of cytology smears and cell block in adrenal lesions.

Background: Cytology of the adrenal gland is a less performed technique even in tertiary care centres; yet cytological evaluation is an important diagnostic tool for assessment of adrenal lesions. Our objective was to evaluate the diagnostic utility of FNAC smears and cellblock with immunohistochemistry (IHC) in lesions of the adrenal.

Material And Methods: We had a total of 50 cases over a period of 2 years where both FNAC smears and cellblocks were taken.
