Congenital mesoblastic nephroma

Congenital mesoblastic nephroma (CMN) is a rare, pediatric renal tumor that typically presents in the first few months of life. It is the most common renal tumor in the first three months of life.

Classification

CMN is classified into two types: classic (or cellular) and mixed (or classic/cellular). The classic type is composed of spindle cells, while the mixed type contains both spindle and round cells.

Symptoms

The most common symptom of CMN is a palpable abdominal mass. Other symptoms may include hypertension, hematuria, and polyhydramnios.

Diagnosis

Diagnosis of CMN is typically made through imaging studies such as ultrasound and computed tomography (CT) scans. A definitive diagnosis is made through a biopsy of the tumor.

Treatment

Treatment for CMN typically involves surgical removal of the tumor. In some cases, chemotherapy or radiation therapy may be used.

Prognosis

The prognosis for CMN is generally good, with a high survival rate. However, the prognosis can vary depending on the type of CMN and the stage at which it is diagnosed.
