Renal oncocytomas are common benign kidney neoplasms that account for 3 to 7 percent of renal neoplasms. They usually occur in adults, most frequently in the seventh decade of life. Renal oncocytomas may be discovered incidentally or may be diagnosed with biopsy or excision.
Is renal cell carcinoma cancer?
Renal cell carcinoma (RCC) is also called hypernephroma, renal adenocarcinoma, or renal or kidney cancer. It’s the most common kind of kidney cancer found in adults. The kidneys are organs in your body that help get rid of waste while also regulating fluid balance.
What is oncocytic renal neoplasm?
Oncocytoma is a term generally used to describe a neoplasm of the renal parenchyma consisting of well-differentiated cells with prominently eosinophilic granular cytoplasm. We report our experience with such tumors and with 4 cases of granular cell carcinoma (grade 2).
Is an oncocytic neoplasm cancerous?
The majority of oncocytic neoplasms is considered to be benign and displays low invasiveness. Prognosis of kidney oncocytoma, Warthin tumor and oncocytic pituitary adenoma is in fact usually favourable.
What is neoplasm disease?
Neoplastic diseases are conditions that cause tumor growth — both benign and malignant. Benign tumors are noncancerous growths. They usually grow slowly and can’t spread to other tissues. Malignant tumors are cancerous and can grow slowly or quickly.
What is the life expectancy of someone with renal cell carcinoma?
In the case of kidney cancer, around 72% of those diagnosed live for at least one year after diagnosis, about 56% live for at least 5 years and about 50% live for 10 years or more.
What percentage of kidney masses are cancerous?
These benign growths include cysts, oncocytomas, angiomyolipomas, and mixed epithelial stromal tumors. Thus, 70-80% of these “small” kidney tumors are cancers and fortunately the majority are “well behaved” (low grade) cancers.
How bad is cancer in the kidney?
The Treatment: Kidney cancer is a serious disease, but in most cases, the earlier it is found, the better the outcome. Kidney cancer can often be cured if found and treated before it has spread. About 30% of those who are diagnosed with renal cell cancer develop advanced (metastatic) disease.
What causes an oncocytoma?
When renal oncocytomas are part of a genetic syndrome, they are caused by changes ( mutations ) in a specific gene . Tuberous sclerosis complex is caused by mutations in the TSC1 gene or TSC2 gene, while Birt-Hogg-Dube syndrome is caused by mutations in the FLCN gene.
Where is oncocytoma found?
Submandibular oncocytomas are rare benign salivary gland neoplasms. They are typically found in Caucasian patients aged 50–70 years with no gender preference. Due to the overlapping histological and clinical features of head and neck tumors, they are often misdiagnosed. Methods.
What is angiomyolipoma in the right kidney?
Angiomyolipoma of the kidney is a clonal neoplasm, apparently part of a family of neoplasms derived from perivascular epithelioid cells. Early angiomyolipomas are small nodules composed of HMB-45-reactive spindle cells in the renal capsule, cortex, or medulla.
What is considered a large kidney tumor?
Every year in the U.S., more than 67,000 new cases of renal cancer are diagnosed, the majority of which are small masses (under 4 cm). However, large renal masses ≥4 cm still account for a significant number of cases.
What is Stauffer syndrome?
Stauffer’s syndrome is a rare paraneoplastic manifestation of renal cell carcinoma (RCC) that is characterized by elevated alkaline phosphatase, erythrocyte sedimentation rate, α-2-globulin, and γ-glutamyl transferase, thrombocytosis, prolongation of prothrombin time, and hepatosplenomegaly, in the absence of hepatic …
What is a parotid oncocytoma?
Parotid gland oncocytoma is an uncommon, benign salivary neoplasm composed of mitochondria-rich epithelial cells called oncocytes. In the parotid gland, oncocytomas most commonly occur in adults in their sixth to eighth decades, with no sex predilection.
Are all Masses on the kidney cancerous?
Some kidney masses are benign (not cancerous) and some are malignant (cancerous). One in four kidney masses are benign. Smaller masses are more likely to be benign. Larger masses are more likely to be cancerous.

How long can you live with one kidney?
This usually takes 25 years or more to happen. There may also be a chance of having high blood pressure later in life. However, the loss in kidney function is usually very mild, and life span is normal. Most people with one kidney live healthy, normal lives with few problems.
Is renal cell carcinoma aggressive?
Collecting duct carcinoma and renal medullary carcinoma are aggressive types of kidney cancer, which doctors find challenging to treat. People with these types of cancer may have a poorer prognosis than people with other types. Doctors also talk about high- and low-grade cancers.
Do benign kidney tumors cause pain?
The kidneys also make red blood cells, control blood pressure, and maintain bone health. Most people do not feel any pain or other symptoms from a small tumor in the kidney, even when the tumor is cancerous.

What is the difference between a tumor and a neoplasm?
The difference between a tumor and a neoplasm is that a tumor refers to swelling or a lump like swollen state that would normally be associated with inflammation, whereas a neoplasm refers to any new growth, lesion, or ulcer that is abnormal.
What are the characteristics of malignant neoplasms?
A malignant neoplasm is composed of cells that look less like the normal cell of origin.
…
Thus, characteristics of malignant neoplasms include:
- More rapid increase in size.
- Less differentiation (or lack of differentiation, called anaplasia)
- Tendency to invade surrounding tissues.
- Ability to metastasize to distant tissues.
