Solid pseudopapillary tumor of the pancreas (SPTP), also known as solid and papillary epithelial neoplasm of the pancreas, is a rare pancreatic exocrine tumor that is difficult to diagnose before surgery. Pancreatic panniculitis is a rare type that occurs in less than 3% of all patients with pancreatic diseases. We here report a 19-year-old woman who presented with persistent left upper quadrant pain without obvious cause for 1 d. The patient also developed subcutaneous nodules involving lower abdomen bilaterally and lower limbs, and subcutaneous nodules were pathologically diagnosed as pancreatic panniculitis. Plain abdominal computed tomography revealed a soft-tissue mass in the body and tail of the pancreas, which was closely associated with the gastric wall. Contrast-enhanced ultrasound showed inhomogeneous echogenicity in the anterior pancreatic body, which had blurred parenchymal demarcation of the body and tail of the pancreas. Contrast-enhanced abdominal computed tomography revealed a mixed density mass with solid and cystic components in the body and tail of the pancreas, and the solid component was markedly enhanced. The lesion was pathologically diagnosed as SPTP after laparoscopic resection. Clinicians should be aware of the clinical manifestation, diagnosis, and treatment of pancreatic panniculitis and SPTP.
Core tip: Pancreatic panniculitis is a rare complication of pancreas diseases, and solid pseudopapillary tumor of the pancreas is a rare pancreatic exocrine tumor that is difficult to diagnose before surgery. We describe the diagnosis and treatment of solid pseudopapillary tumor of the pancreas accompanied with pancreatic panniculitis in a young woman. Plain abdominal computed tomography, contrast-enhanced ultrasound, contrast-enhanced abdominal computed tomography and pathological examinations were performed.
