Transformation5
The latter most prominently shows malignant transformation in the long run, while the former is considered benign [ 1 ]. (hindawi.com)
The mucinous cystadenomas on the other hand, even though slow growing, have high chances of malignant transformation and hence need to be managed earlier, surgically [ 3 ]. (hindawi.com)
