MULTILOCULAR CYSTIC NEPHROMA WITH SHRUNKEN KIDNEY.

This video shows MULTILOCULAR CYSTIC NEPHROMA WITH SHRUNKEN KIDNEY. Multilocular cystic nephroma is a benign mixed mesenchymal and epithelial neoplasm of the kidney and is classically described as a benign slow-growing renal tumor. Patients who have multilocular cystic nephroma present with a palpable mass, abdominal pain, and hematuria, as in renal cell carcinoma. Ultrasound can usually help differentiate between benign and malignant tumors based on shape, location, and a number of other sonographic characteristics. If the ultrasound is inconclusive, your doctor may request a follow-up ultrasound to monitor the tumor or a radiologist may recommend a biopsy. Multilocular cyst A cyst contains several compartments formed by membranous septa. Multilocular cystic nephroma (MLCN) is a benign mixed mesenchymal and epithelial neoplasm of the kidney. MLCN is classically described as a benign slow-growing renal tumor, and there are more than 200 cases reported in the literature. Cystic nephroma is diagnosed by biopsy or excision. It is important to correctly diagnose them as, radiologically, they may mimic the appearance of a renal cell carcinoma that is cystic. Nephroma is a tumor of the kidney cortex. The renal cortex is the outer portion of the kidney that filters the blood and removes waste inside the body. There are several kinds of nephroma, which fit into two main types: non-cancerous (benign) and cancerous (malignant). A renal mass, or tumor, is an abnormal growth in the kidney. Some renal masses are benign (not cancerous) and some are malignant (cancerous). One in four renal masses is benign. • A discrete multiseptated cystic mass that primarily involves the kidney. • A well-marginated, rounded, or polycyclic cortical mass that extends beyond the normal renal outline. • This mass contains cysts that vary in size and number. It may be a cluster of a few large cysts with thick walls and septa, or it may be a denser mass composed of tiny cysts. • Enhancement of the septae may be seen due to the presence of thin vessels in the septae. Kidney cancer is caused when DNA in cells in one or both kidneys mutate, which may lead to uncontrolled cell division and growth. While the exact cause of a person's kidney cancer may not be known, certain risk factors are strongly linked to the disease, including smoking tobacco and obesity. A mass or lump in the abdomen, side or back can also be a sign of kidney cancer. It can feel like a hard, thickening, or bulging bump under the skin. About 45 percent of people with RCC have an abdominal mass. But kidney lumps are hard to feel, especially in the early stages. Renal cell cancer also called renal adenocarcinoma, or hypernephroma can often be cured if it is diagnosed and treated when still localized to the kidney and to the immediately surrounding tissue. The probability of cure is directly related to the stage or degree of tumor dissemination. A kidney ultrasound may be used to assess the size, location, and shape of the kidneys and related structures, such as the ureters and bladder. Ultrasound can detect cysts, tumors, abscesses, obstructions, fluid collection, and infection within or around the kidneys. A CT scan is also sometimes called a CAT scan (Computerized Axial Tomography). While CT scans do show a bit more detail than an ultrasound, they still cannot identify cancerous tissue – and this can easily lead to false negatives. PET/CT scans, on the other hand, provide you with far more accurate and detailed results. Because kidney cancer cells usually do not respond well to chemo, chemo is not a standard treatment for kidney cancer. Some chemo drugs, such as cisplatin, 5-fluorouracil (5-FU), and gemcitabine have been shown to help a small number of patients. In a large retrospective study by Frank et al.,10 2,935 solid renal tumors were treated in a 30-year period. Of these tumors, 12.8% were benign and 87.2% were malignant. Of the tumors more than 1 cm in diameter, 46.3% were benign while 98% of malignant tumors were low grade. Imaging tests such as computed tomography (CT) scans and magnetic resonance imaging (MRI) scans can often find small kidney cancers, but these tests are expensive. Ultrasound is less expensive and can also detect some early kidney cancers. Renal masses can be divided into cystic and solid lesions. The most common are cysts in up to 27% of patients over 50 years. CT- or MRI-enhancing masses are classified as solid or complex cystic. Eighty-five percent of expansive solid masses are malignant. Solid kidney tumors can be benign, but most often are found to be cancer. Kidney cancer is one of the top 10 most common cancers diagnosed in the United States. Nearly 15,000 people will die from this disease in 2020. Of the people who are diagnosed early (stage I or II cancer), 75-80% will survive.
