Oncocytic and clear cell areas in a solid pseudopapillary tumor of the pancreas: a case report

ABSTRACT

Solid pseudopapillary tumor [SPT] of pancreas is a rare, distinct, low-grade malignant neoplasm. Variable areas like clear cell foci can exist in this tumor, which can easily mislead the pathologist. Diagnosis of the same is important to distinguish from other clear cell lesions in the pancreas. Oncocytoid differentiation is rarer still and can raise doubts about the diagnosis, especially on trucut biopsies. Herein, we discuss a case of SPT of the pancreas exhibiting variable cellular morphology, of which very few cases have been reported in world literature
