Solid-pseudopapillary neoplasm of the pancreas in children: can we predict malignancy?
Histologic malignant SPN has high risk of recurrence. We should consider more radical resection when finding a predominantly solid tumor in a CT scan.
The presence of AUTF in noninstrumented VU is associated with low rates of urothelial neoplasia but a statistically higher risk of urothelial neoplasia than the presence of BUTF (10.0% vs 4.4%; P<.05). In particular, the rate of high-grade urothelial carcinoma is significantly higher in noninstrumented VU specimens containing AUTF than those containing BUTF (8.8% vs 0.7%; P<.0001). In addition, urolithiasis is associated with AUTF in a substantial percentage of noninstrumented VU specimens.
