3–7% of people having duodenal biopsy Duodenal lymphocytosis , sometimes called lymphocytic duodenitis , lymphocytic duodenosis , or duodenal intraepithelial lymphocytosis , is a condition where an increased number of intra-epithelial lymphocytes is seen in biopsies of the duodenal mucosa when these are examined microscopically.
Monoclonal immunoglobulins are produced by monoclonal plasma cells, which are found in a variety of plasma cell dyscrasias. The deposition of monoclonal immunoglobulins on the basement membrane of the kidney causes renal impairment. As well as the kidney, MIDD may also affect the liver, heart, peripheral nerves, lung and skin.
Clear Cell Renal Cell Carcinoma (CCRCC) Generally the cells have a clear cytoplasm, are surrounded by a distinct cell membrane and contain round and uniform nuclei. 60–70% Alterations of chromosome 3p segments occurs in 70–90% of CCRCCs; Inactivation of von Hippel–Lindau (VHL) gene by mutation and promoter hypermethylation; Gain of ...
Generally, the cells have a clear cytoplasm, are surrounded by a distinct cell membrane and contain round and uniform nuclei. [citation needed]Microscopically, CCRCCs are graded by the ISUP/WHO as follows: [1] [2]

Renal biopsy (also kidney biopsy) is a medical procedure in which a small piece of kidney is removed from the body for examination, usually under a microscope. [1] Microscopic examination of the tissue can provide information needed to diagnose, monitor or treat problems of the kidney.
Papillary renal cell carcinoma (PRCC) is a malignant, heterogeneous tumor originating from renal tubular epithelial cells of the kidney, which comprises approximately 10-15% of all kidney neoplasms. [1] Based on its morphological features, PRCC can be classified into two main subtypes, which are type 1 and type 2 (eosinophilic). [2]
Light chain deposition disease can affect any organ. [3] Renal involvement is always present and can be identified by microscopic hematuria and proteinuria.Due to the gradual buildup of light chains from plasma filtration, renal function rapidly declines in the majority of patients with LCDD as either acute tubulointerstitial nephritis or rapidly progressing glomerulonephritis.
