After being described by Edmunds first as cystic nephroma
(3), various descriptions, such as "multilocular cystic tumor", "renal multilocular cyst", "multilocular cystic nephroma
", "renal cystic hamartoma", "partial polycystic kidney" and "polycystic nephroma
", have been made in the literature (4).
In our study a case of mesoblastic nephroma
was observed in a six months male child.
corticolous Myriolecis dispersa (Pers.) Sliwa, Zhao Xin & Lumbsch saxicolous Nephroma
Congenital mesoblastic nephroma
is the most common renal tumor in the newborn, with a mean age of presentation of less than 3 months and an association with polyhydramnios .
This is to incorporate pleuropulmonary blastoma, cystic nephroma
, and pineoblastoma and other rarer phenotypes of DICER1 syndrome.
A recent  report highlighted the association of NCMH and PPB with DICER1 mutation and various associated entities such as lung cysts, cystic nephroma
, renal sarcoma, Wilms tumor, thyroid hyperplasia, and CNS tumors.

," Pediatric Nephrology, vol.
This category also includes complicated hemorrhagic or infected cysts, multilocular cystic nephroma
, and cystic neoplasms.
Differentials for a cystic-solid abdominal mass with calcifications in neonates and early infancy include mesoblastic nephroma
, neuroblastoma, gastrointestinal stromal tumors, lymphangiomas, and teratomas.
It is to be noted that these fusions have also been observed in other neoplasms such as acute myeloid leukemia, congenital mesoblastic nephroma
, and fibrosarcoma,  suggesting that the fusion protein has transforming activity in cells of different lineages.

For this reason, Quercus suber trunks that are covered with moss are colonized by certain humicolous species such as Nephroma
resupinatum and Normandina pulchella, which grow in wet woodlands.
