Abstrakt: A 32-year-old lady presented with a history of abdominal pain and upper abdominal discomfort of 3 months duration. Her imaging studies done at a local hospital showed a solid-cystic mass involving head of the pancreas. The patient was referred to our surgical oncology department. On examination, there was a nontender mass in the epigastrium. An ultrasound scan guided fine-needle aspiration (FNA) was done which was showing classical features of solid-pseudo papillary neoplasm of the pancreas. With this preoperative diagnosis patient was taken up for surgery. Per operatively, there was a solid-cystic mass in the head of the pancreas. Pancreaticoduodenectomy was done. Histopathology and immunohistochemistry (IHC) confirmed the diagnosis of solid-pseudo papillary neoplasm of the pancreas. Apart from the routine IHC panel, CD 99 immunostain was also done which demonstrated the characteristic paranuclear dot-like staining observed in previous studies in the literature.
