“…IMT, first reported in the lungs[ 8 , 9 ], is a special type of disease that is often termed differently in primary research, including designations such as plasma cell granuloma, plasma cell pseudotumor, inflammatory pseudotumor, inflammatory fibroxanthoma and histiocytoma[ 10 ]. IMTs can occur almost anywhere in the body, including the lungs, liver, bladder, mesentery and neck[ 11 - 13 ]. However, an IMT arising from the pancreas is extremely rare.…”

BACKGROUND Pancreatic inflammatory myofibroblastic tumor (IMT) is a relatively rare disease that is often confused with pancreatic cancer or pancreatic neuroendocrine tumors. The histological features of IMTs show that tissue from this type of tumor contains an intermingling of fibroblast and myofibroblast proliferation, accompanied by a varying degree of inflammatory cell infiltration. CASE SUMMARY The management of an IMT occurring at the neck of the pancreas is presented in this paper. A 66-year-old female patient was diagnosed with a pancreatic neck mass after a series of tests. The patient underwent enucleation of the pancreatic neck tumor after a pathological diagnosis of IMT. Previous research on the clinical features, pathological diagnosis and treatment of pancreatic IMTs was reviewed. Compared with previous reports, this is a unique case of enucleation of a pancreatic IMT. CONCLUSION The enucleation of pancreatic IMTs may be a safe and efficient surgical method for managing such tumors with a better prognosis. Further cases are required to explore surgical measures for pancreatic IMTs.

“…It mainly affects the soft tissue and visceral regions of children and young adults. It was first identified in a lung specimen in 1939, and has been classified as a soft tissue tumor since 2002 ( 2 ). Its histopathological features usually include a spectrum of fibroblastic or myofibroblastic proliferation with different infiltrations of inflammatory cells, including plasma cells, lymphocytes, and histiocytes.…”

An inflammatory pseudotumor is considered a benign form of lesion marked by a proliferation of myofibroblasts with different degrees of inflammatory infiltrates. Pulmonary inflammatory pseudotumors (PIPs) are extremely rare in middle-aged adults. Normally, a PIP has a single lesion, and can be controlled constantly by surgery and drugs. In this paper, we report a case study of a 51-year-old male patient who presented with multiple inflammatory pseudotumors in lungs, thoracic spine, ribs, left humerusl, derived from PIPs throughout his body, which indicated a long disease term and significant recrudescence. After 6 surgeries (a wedge resection of the right lower lobe, a removal of three thoracic vertebral lesions, a removal of left humeral tumor lesion, a right lower lobe resection, local cryoablation of right lung, debridement of left upper-arm osteomyelitis and soft tissue infection), radiotherapy for lesions of left humerus destruction at a total dose of 20 Gy/10 F, and systematic treatments (30 mg prednisone acetate daily for 6 weeks, 50 mg compound cyclophosphamide tablets for 2 weeks; antibiotics, blood transfusions, nutritional support), his symptoms improved but reoccurred. The patient ultimately died of septic shock. Our case report highlights that the progression of a PIP to a malignant form requires further research. A multiple-lesion PIP that does not respond to systemic treatment can be highly dangerous.

Background Pancreatic inflammatory myofibroblastic tumor (IMT) is a relatively rare disease, which is often confused with pancreatic cancer or pancreatic neuroendocrine tumor. Its histological features are fibroblast and myofibroblast proliferation, accompanied by varying degrees of inflammatory cell infiltration. Case presentation Herein, we presented the management of IMT occurring at the neck of pancreas. A 66-year-old female patient was diagnosed as pancreatic neck mass after a series of tests. Then she underwent enucleation of pancreatic neck tumor followed by pathological diagnosis of IMT. Meanwhile, we reviewed the clinical features and pathological diagnosis and treatment of pancreatic IMT which were previously reported. To our knowledge, this is the unique case of enucleation of pancreatic IMT. In the management of pancreatic IMT, Conclusion we concluded that enucleation may be a safe and efficient surgical method for the management of pancreatic IMT and may also provide a better prognosis. Further accumulation of cases is required to explore the surgical measure of pancreatic IMTs.
