Abstract
A solid pseudopapillary tumour (SPT) is an uncommon pancreatic tumour. Very rarely it has also been described outside the pancreas, usually arising from heterotopic pancreatic tissue. In this paper, we described a case arising from the transverse mesocolon without heterotopic pancreatic tissue in an 18-year-old girl.
Highlights
Solid pseudopapillary tumour (SPT) of the pancreas is one of the rare found primary tumors of the pancreas, making up approximately 0.17–2.7% of cases [1]
To the best of our knowledge, this is the first SPT originating from mesocolon without ectopic pancreas tissue
SPT is a rare disease with a reported incidence of 0.13% to 2.7% of all pancreatic tumors [3], and cases often have been misunderstood
Summary
Solid pseudopapillary tumour (SPT) of the pancreas is one of the rare found primary tumors of the pancreas, making up approximately 0.17–2.7% of cases [1]. There have been controversies regarding the terminology and according to its macroscopic and microscopic pathological characteristics over the years. It has been given multiple descriptive names such as papillary-cystic tumour, solid cystic tumor, papillary epithelial neoplasm, solid, and papillary neoplasm, papillary tumour of the pancreas, or Frantz’s tumor [1] until in 1996 the WHO pancreatic tumour working group recommended the use of the term solid pseudopapillary neoplasm [2]. To the best of our knowledge, this is the first SPT originating from mesocolon without ectopic pancreas tissue
