What is multilocular cystic nephroma?
Multilocular cystic nephroma (MLCN) is a benign mixed mesenchymal and epithelial neoplasm of the kidney [1]. MLCN is classically described as a benign slow-growing renal tumor, and there are more than 200 cases reported in the literature.
What is multilocular cyst of kidney?
Multilocular renal cyst is a distinct renal tumor whose gross external appearance and absence of normal renal tissue within the septa of loculi distinguish it clearly from other renal cystic lesions. Interlocular septa may contain either (1) fibrous tissue alone or (2) embryonic tissue separating adjacent loculi.
What is a Multiloculated cyst?
1. a cyst containing several loculi or spaces. 2. a hydatid cyst with many small irregular cavities that may contain scoleces but generally little fluid.
What is Mesoblastic Nephroma?
Mesoblastic nephroma (also called fetal renal hamartoma) is the most common renal tumor identified in the neonatal period and the most frequent benign renal tumor in childhood. It represents 3-10% of all pediatric renal tumors. This tumor was first described as a separate entity by Bolande et al in 1967.
What is a Nephroma?
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).
What is a renal tumor?
Kidney tumors (also called renal tumors) are growths in the kidneys that can be benign or cancerous. Most do not cause symptoms and are discovered unexpectedly when you are being diagnosed and treated for another condition.
What is Multilocular Radiolucency?
Introduction Multilocular radiolucency refers to a lesional appearance on the radiograph which is derived from erosion, bosselation, or scalloping of the endosteal surface at the advancing margin of the lesion, thus giving the charecteristic multiple loculated appearance.(1)
Is a dermoid cyst a complex cyst?
Complex cysts The following are three common types of complex ovarian cysts: Dermoid cysts are made up of cells you had since before you were born. Your body uses these cells to produce dermal tissue so they may contain fat, skin, hair, or even teeth. Cystadenomas contain ovarian tissue with fluid or mucus.
What is the meaning of multilocular ovary?
Locule refers to a cavity or chamber present in the ovary present in the plant which contains the ovules and seeds. 2) Multilocular ovary: Multilocular ovaries refers to those ovaries which consists of large number of locules.
Is Mesoblastic Nephroma benign?
Mesoblastic nephroma, also sometimes known as a congenital mesoblastic nephroma (CMN), Boland’s tumor or fetal renal hamartoma, is, in general, a benign renal tumor that typically occurs in utero or in infancy.
How rare is cystic Nephroma?
Multilocular cystic nephroma is a rare entity of benign multicystic renal tumor. It was first described in 1892, and only approximately 200 cases have so far been reported in the related literature. The diagnosis is made based exclusively on the pathological finding.
What kind of tumor is multilocular cystic nephroma?
Multilocular cystic nephroma (MLCN) is a benign mixed mesenchymal and epithelial neoplasm of the kidney [1]. MLCN is classically described as a benign slow-growing renal tumor, and there are more than 200 cases reported in the literature.
What’s the difference between cystic nephroma and CPDN?
Cystic nephroma and CPDN are indistinguishable from one another based on their gross and radiographic appearances (, 3) and can be lumped under the term multilocular cystic renal tumor (MCRT) (, 4 ). MCRT was first described in the late 19th century as cystic adenoma.
When does a cystic nephroma MCRT occur?
MCRT has a bimodal age and sex distribution and tends to occur in children (mostly boys with CPDN) between 3 months and 4 years of age and in adults (mostly women with cystic nephroma) between 40 and 60 years of age (,4,,8,,9). MCRT is usually solitary, but bilateral tumors have been described (,10).
Is the DICER1 gene mutation associated with cystic nephromas?
Cystic nephromas, previously known as multilocular cystic nephromas, are rare benign renal neoplasms classically occurring in adult females in the 4 th and 5 th decades. As of the 2016 WHO classification, they are considered distinct from pediatric cystic nephromas which have associated DICER1 gene mutation 10,11,14.
