The recent 2009 WHO classification of tumours of pancreas named this clinical entity as "Solid pseudo papillary tumour
of pancreas", keeping in view the two most characteristic morphological findings; solid and pseudo-papillary pattern of growth.
A H & E stained section of the breast core biopsy showed multiple fragments of low grade papillary tumour
comprising fibrovascular cores lined by cells with overlapping nuclei, occasional nuclear grooves and rare intranuclear inclusions (Figure 3).
This tumour was a follicular variant of a papillary tumour
, with anaplastic dedifferentiation.
At cystoscopy, a 2 x 2-cm papillary tumour
in the region on the bladder
The largest tumour measured 27 cm in diameter in a 45 yr old lady diagnosed as serous papillary tumour
of borderline malignancy.
The papillary tumour
in this case was easily identifiable, as it was clearly delineated and obviously different from the surrounding oncocytoma on H&E stained sections.
Their typical gross and histological features include cystic, solid and pseudopapillary components, which led to a variety of other names including solid cystic tumour, papillary cystic tumour, papillary epithelial neoplasia, solid and papillary epithelial neoplasia, papillary epithelial tumour, solid and papillary tumour
, solid-cystic papillary epithelial neoplasm, benign or malignant papillary tumour
of the pancreas, and adenocarcinoma of the pancreas in childhood.
Small papillary tumour
foci were identified in the adjacent normal renal parenchyma.
In addition, patients of either sex, diagnosed with a papillary tumour
and males with TCC had an increased relative risk of developing a second primary when compared to their respective reference populations.
