These tumors represent less than 2% of pancreatic cancers and mainly affect young women. They can reach a significant size and its radiological features can lead to diagnostic pitfalls, such as gastrointestinal stromal tumors, which are rare soft-tissue sarcomas that can appear anywhere along the gastrointestinal tract. Clinicians and radiologists need to be aware of the existing diagnostic pitfalls between these two entities, because of their possible similarities. We report here the case of a 33-year-old woman with a solid pseudopapillary epithelial neoplasms of the pancreas initially misdiagnosed as an exophytic gastric stromal tumor.  \nKeywords  \nSolid pseudopapillary tumor, gastrointestinal stromal tumors, imaging pitfalls  \nDate received: 25 December 2023; accepted: 29 April 2024  \nIntroduction  \nSolid pseudopapillary epithelial neoplasms of the pancreas (SPEN) are rare entities, first described in 1959 by Frantz.1 These tumors represent less than 2% of pancreatic cancers, mainly affect young women and thought to generally affect people of Asian or African-American origin.2,3 They can reach a significant size, with an average of 10 cm at the time of diagnosis,4 while remaining poorly symptomatic orasymptomatic. Its size and its radiological features can lead to diagnostic pitfalls, particularly with gastrointestinal stromal tumors (GIST), which are rare soft-tissue sarcomas that can appear along the gastrointestinal tract. The most common site is the stomach, followed by the small intestine, colon, and rectum.5 We report here the case of a 33-year-old woman with a SPEN initially misdiagnosed as an exophytic gastric stromal tumor.  \nCase report  \nA 33-year-old Guinean woman, with a past medical history of diabetes, presented with a chronic left upper quadrant  \npain, with an abdominal mass, progressively increasing in size. The patient underwent a median laparotomy in her country 2 years ago, which resulted in a splenectomy (surgical procedure unknown; documents were missing) .  \nOn admission, clinical examination revealed a fixed mass deep in the left upper quadrant, extending beyond the costal margin. Tumor markers Carcinoembryonic antigen (CEA) and CA19-9 were normal.  \n1 Department of Gastroenterology 1, Mohammed V Military Training Hospital, Rabat, Morocco  \n2Department of Pathology, Mohammed V Military Training Hospital, Rabat, Morocco  \n3Department of Radiology, Mohammed V Military Training Hospital, Rabat, Morocco  \n4Camp Samory Touré Military Hospital, Conakry, Guinea 5Department of Digestive Surgery I, Mohammed V Military Training Hospital, Rabat, Morocco  \nCorresponding Author:  \nAmine Achemlal, Department of Gastroenterology 1, Mohammed V Military Training Hospital, Abderrahim Bouabid Avenue, Rabat 10100, Morocco.  \nEmail: [achemlal.amine@gmail.com](achemlal.amine@gmail.com)  \nCreative Commons Non Commercial CC BY-NC: This article is distributed under the terms of the Creative Commons AttributionNonCommercial 4.0 License ([https://creativecommons.org/licenses/by-nc/4.0/](https://creativecommons.org/licenses/by-nc/4.0/)) which permits non-commercial use, reproduction and  \ndistribution of the work without further permission provided th","cbCaihpXmfiCcyRM","https://ap.wps.com/l/cbCaihpXmfiCcyRM","pdf",1216058,"English","# Abstract\n# Introduction\n# Case report\n## Imaging and biopsy findings\n## Pathology and immunohistochemistry\n## MRI and final assessment","[{\"question\":\"What is the main diagnostic issue discussed in this case report?\",\"answer\":\"The pancreatic solid pseudopapillary tumor was initially mistaken for an exophytic gastrointestinal stromal tumor (GIST) due to overlapping radiological features.\"},{\"question\":\"Who is the patient and what were the presenting symptoms?\",\"answer\":\"A 33-year-old woman presented with chronic left upper quadrant pain and an abdominal mass that progressively increased in size.\"},{\"question\":\"Which imaging modalities contributed to the diagnostic confusion and clarification?\",\"answer\":\"CT suggested a gastric stromal tumor, ultrasound-guided biopsy suggested SPEN, and pancreatic MRI demonstrated a lesion originating from the pancreatic tail.\"}]","Solid pseudopapillary tumor of the pancreas mistaken for gastrointestinal stromal tumor - A case report - read online free | PDF",1790014401,15]
