Macroscopically, the mass was a tortuous tubular cyst. The nodular fatty component indicated on preoperative images was not a part of the mass but rather a part of the normal retroperitoneal fat that the complex cyst enfolded.
In addition, MPR images also clearly revealed a tortuous tubular cyst. This image reconstruction technique is of great value for grasping the three-dimensional anatomy of a lesion .
"It ended up being three hours and my appendix was almost rotten and I had a tubular cyst
the size of a pencil and cysts on my ovaries.
VHL-gene deletion in single renal tubular epithelial cells and renal tubular cysts
: further evidence for a cyst-dependent progression pathway of clear cell renal carcinoma in von Hippel-Lindau disease.
The main renal complications of lithium toxicity/ nephropathy are glomerular in nature and include focal segmental glomerulosclerosis, interstitial fibrosis, and glomerular or tubular cysts. (164-169) Cyst formation was originally reported in up to 40% of patients treated with lithium, (170,171) but GCK due to lithium toxicity appears underappreciated.
Even though no one antibody alone distinguished glomerular from tubular cysts, medullary cysts with vague cylindrical shapes may be better visualized with immunohistochemistry (eg, Figure 4, A through C represents ARPKD).
They are characterized by renal tubular cysts lined by a single layer of cuboidal, occasionally ciliated cells with hyperchromatic nuclei and scanty cytoplasm reminiscent of the primitive renal tubules normally seen during renal development, as well as immature glomeruli or renal tubules separated by an immature mesenchyme that tends to form hypercellular concentric rings with frequent myofibroblastic differentiation around the cysts or primitive tubules.
As mentioned above, because renal neoplasm in the context of ESRD may develop de novo or through tubular cysts, these nephrectomy specimens may or may not show additional ACKD changes.
