Solid Pseudopapillary Neoplasms (SPN) of the pancreas is rare tumors of low malignant potential composed of solid and cystic pseudopapillae which predominantly affect young females [1]. The first documentation of this lesion was by Lichtenstein in 1933, who described a young female presenting with a large abdominal tumor from which she ultimately died. At necropsy, she was found to have a large...
CONTEXT Solid pseudopapillary tumour of the pancreas is an uncommon tumour, which predominantly occurs in young females and is of unknown origin. CASE REPORT We describe five cases with diverse clinical and/or histological features, including one unusually aggressive case resulting in early death. CONCLUSION There is great variability in the presentation and clinical course of these tumours...
We report a case series of three children with solid pseudopapillary tumor of the pancreas (SPT) in which a complete radiological work-up, including ultrasound, computed tomography scans, and MRI, has been carried out. The aim of this article is to highlight the characteristic imaging findings of SPT in the pediatric age group and to establish a correlation with typical histopathological findin...
Papillary glioneuronal tumor (PGNT) is a rare brain tumor (World Health Organization grade I) with a glioneuronal dual nature. It has a characteristic morphological pattern composed of astroglial pseudopapillary structures and interpapillary neurocytic elements. The tumor usually occurs in the supratentorial region in children and young adults, with a predilection for the temporal lobe. It is t...
Multiple endocrine neoplasia (MEN1) is a rare autosomal dominant disorder characterized by primary hyperparathyroidism, enteropancreatic neuroendocrine tumors, and anterior pituitary adenomas. A 16-year-old male presented to the emergency outpatient clinic with tonic convulsions. Physical examination in the postconvulsive period was unremarkable and revealed a muscular, postpubertal adolescent....
Solid pseudopapillary tumors (SPTs) occurring as primary tumors outside the pancreas are exceedingly rare. The present study reports such a case occurring as a non-functional adrenal tumor in a 22-year-old female. The tumor was completely removed from the retroperitoneum by laparoscopic surgery. A well-defined, encapsulated tumor measuring 6×6×5 cm was histologically characterized by a combinat...
