Gastric inflammatory myofibroblastic tumor presented with severe anemia and inflammation: a case report. Surg Case Rep 2024; 10:5. [PMID: 38185719 PMCID: PMC10772034 DOI: 10.1186/s40792-023-01802-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2023] [Accepted: 12/24/2023] [Indexed: 01/09/2024] Open
Abstract
BACKGROUND Inflammatory myofibroblastic tumor (IMT) is a rare stromal tumor, often found in children and young adults, and most commonly occurs in the lungs. Surgical resection is considered the standard treatment for localized IMT, although only limited data exist. Gastric IMT in adults is extremely rare, and there are no established guidelines for its treatment. CASE PRESENTATION A 69-year-old male presented with persistent fatigue and weakness. Laboratory examination revealed severe anemia and inflammation. Upper gastrointestinal endoscopy at admission revealed a 40-mm type I softish tumor in the lesser curvature of the gastric body, without apparent hemorrhage. Repeated biopsies, including partial resection with snare, failed to give a definitive diagnosis. Computed tomography (CT) revealed a massive lesion at the gastric body, protruding into the gastric lumen, which was consistent with the gastric tumor. After admission, the patient developed anemia refractory to frequent blood transfusions despite the absence of apparent gastrointestinal bleeding. In addition, the patient had recurrent fevers of 38 °C or higher, and persistent high inflammatory levels. Fluorodeoxyglucose-positron emission tomography (FDG-PET) CT 1 month after the first visit exhibited an increased FDG uptake in the gastric tumor. In addition, this CT scan revealed a rapid increase in tumor size to 75 mm. It was suspected that the undiagnosed gastric tumor caused these serious clinical symptoms, and he underwent distal gastrectomy and cholecystectomy. The gross image of the tumor showed an 80-mm cauliflower-like shape with a gelatinous texture. The histopathological diagnosis was IMT. The postoperative course was uneventful, and the patient's symptoms subsided drastically, improving both anemia and systemic inflammation. The patient has shown no recurrence or relapse of the symptoms over one and a half years. CONCLUSIONS In this case, the tumor resection finally enabled the diagnosis of IMT and resolved the clinical symptoms. Despite its predominantly benign morphological nature, some cases of IMT present clinically adverse courses. Surgical treatment may lead to its final diagnosis and improvement of clinical symptoms.

Abstract
BACKGROUND The inflammatory myofibroblastic tumor (IMT) is a rare mesenquimal tumor of doubtful biological behaviour. It's characterised for affecting mainly children and young adults, although it can appear at any age, being the lungs the primary affected organ (in children it represents 20% of all primary pulmonary tumors). CASE SUMMARY We present the case of a 45 year old woman, with a computed tomography (CT) finding of injury on the anterior surface of the fundus/gastric body and a solid perigastric injury of 12 mm in the ecoendoscopy. The case is presented in the tumor committee deciding to perform a laparoscopic wedge resection. The histological diagnosis was a IMT. The diagnosis is based on imaging tests like the abdominal CT, abdominal ecography and the ecoendoscopy but to confirm the diagnosis a pathological study is necessary. CONCLUSION Due to the unpredictable nature of this tumor, surgical resection is the best therapeutic option.

Abstract
An inflammatory myofibroblastic tumor (IMT) is a very rare tumor of mesenchymal origin with unclear etiopathogenesis, no unique diagnostic features, and no specific management protocol. It is often confused with inflammatory pseudotumor in literature, and the distinction needs further study. The average size, recurrence risk, and metastatic potential differ as per the site of origin. The abdomen is a very rare site for IMTs. Hepatic IMTs (H-IMTs) are reported to be solid tumors with sizes ranging from 1 cm to 20 cm in literature, and gastric IMTs (G-IMTs) range from 3 cm to 10 cm in size and can be solid-cystic. We report here a case of a 36-year-old gentleman with a 34x27x17 cm solid-cystic lesion in the lesser sac with loss of fat planes with stomach and left hemi-liver. The patient was managed by complete surgical resection of the lesion with wedge gastrectomy and wedge hepatectomy and recovered uneventfully. To our knowledge and based on our literature review, this case presents the largest reported and solid-cystic G-IMT with the involvement of left hemi-liver in a young gentleman and discusses its management as well as the relevant literature on this rare entity. This clinical presentation of G-IMT should be kept in the differential diagnosis in a relevant case presenting in the future. Immunohistochemistry is a must to establish the diagnosis, and surgical resection to negative margins is the management option of choice in resectable cases.

Inflammatory myo-fibroblastic tumor of appendix: A rare clinical entity. Int J Surg Case Rep 2021; 89:106607. [PMID: 34823164 PMCID: PMC8627983 DOI: 10.1016/j.ijscr.2021.106607] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2021] [Revised: 11/07/2021] [Accepted: 11/13/2021] [Indexed: 11/27/2022] Open
Abstract
Introduction Inflammatory myo-fibroblastic tumor of appendix is one of the rarest clinical findings and less has been described in the literatures. So, we aimed to present the clinical case that we encountered at our institute. Presentation of a case A 29-year-old lady presented with history of pain at the periumbilical area for one day which shifted to right iliac fossa. Clinical examination revealed tenderness and rebound at right iliac fossa with increased total leucocyte count and ultrasonography abdomen showed swollen appendix. Intraoperatively, a lump around 4 × 3 cm was evident at the tip of appendix with cut section revealing pus along with fecalith. Appendectomy was done with no spillage of the content within the peritoneal cavity. Histopathology revealed inflammatory myo-fibroblastic tumor of appendix. Patient is on regular follow up. Discussion Inflammatory myo-fibroblastic tumor of appendix is one of the rarest clinical findings that mimics malignancy. Presentation could be that of acute appendicitis and in most instances, diagnosis is made intraoperatively. Surgical removal is the mainstay of treatment with regular follow up of the patient for chances of recurrences. Histologically, edematous stroma consisting of inflammatory infiltrates composed of lymphocytes, plasma cells, eosinophils and focal formation of lymphoid follicles along with the proliferation of scattered spindle to ovoid cells with proliferating blood vessels with unremarkable over lying epithelium is evident. Myo-fibroblastic origin can be confirmed by immunostaining with smooth muscle specific vimentin and actin. Conclusion Inflammatory myo-fibroblastic tumor of appendix can present with features of acute appendicitis and may mimic malignancy. Appendectomy with regular follow up is mandated if such clinical cases are encountered. Inflammatory myo-fibroblastic tumor is a pseudo sarcomatous condition Appendiceal involvement is pretty rare. Clinical presentation may mimic that of acute appendicitis. Surgical removal and regular follow up are the main stay of treatment.

Abstract
Inflammatory pseudotumors of the esophagus are extremely rare, and the treatment has been controversial. Herein, we report a case of esophageal inflammatory pseudotumor with low-dose corticosteroid treatment following surgery. A 50-year-old woman with a 3-month history of progressive dysphagia and weight loss, was admitted to our hospital for examination and treatment. Esophagography and endoscopic examination revealed a mass present from the cervical esophagus to the upper thoracic esophagus with severe esophageal stricture. Ultrasound-guided fine needle aspiration cytology, boring biopsy, and mucosal incision-assisted biopsy reveal chronic inflammation, but histological diagnosis was not proven. Surgery was performed to confirm diagnosis and to relieve esophageal stricture. However, because of dense adhesions around the tumor, complete tumor resection was not achieved. Histopathological examination showed an inflammatory infiltrate with plasma cells, eosinophils, neutrophils, and lymphocytes, suggesting an inflammatory pseudotumor. After surgical resection, the esophageal stricture remained, possibly due to the residual tumor. We used a postoperative low-dose steroid treatment that resulted in complete resolution. There has not been any evident sign of recurrence for more than 2 years.

Abstract
Inflammatory myofibroblastic tumor is a rare soft tissue tumor which can be detected in many parts of the body. Its etiology and clinical behavior are not fully understood, and its treatment is controversial. This study aimed to present the management of a pancreatic tail case presenting with extracolonic obstruction findings. Unblock distal pancreatectomy + left surrenalectomy + left hemicolectomy + splenectomy operation was made with R0 resection principles. Although there are some medical treatments reported in children and unresectable tumors in the medical literature, complete surgical resection following oncological principles seems to be the most important and main treatment modality in the treatment of inflammatory myofibroblastic tumors. However, inflammatory myofibroblastic tumor has many aspects that are not yet clearly understood, and it is a disease being continuously researched.

Abstract
Introduction: Intussusception occurs when part of the intestine slides into an adjacent intestinal segment. Inflammatory myofibroblast tumor is a rare cause of this condition, and is observed in 5% -16% cases in adults.Case presentation: A 41-year-old woman presented with abdominal pain and distension. A exploratory laparoscopy was performed, finding ileocolic intussusception into the transverse colon. Due to uncontrollable bleeding, the procedure was converted to laparotomy; resection and latero-lateral ileocolic anastomosis were performed. Histopathology reported inflammatory myofibroblastic tumor, with a favorable postoperative evolution. The patient was discharged on the sixth postoperative day.Discussion: When located in the small intestine, 57% of the tumors that cause intussusception are benign, including the myofibroblastic tumor in this patient. The symptoms and signs associated with this neoplasm are cramp-like abdominal pain, nausea and vomiting. Although imaging studies may lead to suspect this diagnosis, in most cases it is made intraoperatively. Surgical resection of the affected intestinal segment is curative, with favorable prognosis.Conclusions: This case is considered as a rare cause of intussusception. It had a benign course and is still under study since its pathophysiology has not been fully understood.

Abstract
Inflammatory myofibroblastic tumor (IMT) is currently recognized as an intermediate mesenchymal neoplasm. It can arise anywhere in the body, but it is particularly common in the lungs. Gastric IMT is very rare in adults. In this study, we report a case of a 68-year-old woman with IMT in the gastric cardia, with invasion into the spleen and diaphragm. Because of its location and aggressive clinical features, it was first mistaken for gastric cancer. However, pathology and immunohistochemistry were used to finally confirm the diagnosis of IMT after total resection of the tumor and spleen and partial resection of the diaphragm. In order to provide better understanding of this rare tumor, targeted next-generation sequencing (NGS) and IHC were performed to assess genetic and protein abnormalities of the tumor. Both IHC and NGS were found to be negative for ALK or other gene fusions. However, double amplification of CDK4 and MDM2 were found by NGS, and IHC also found CDK4 and MDM2 to be positive. To the best of our knowledge, this is the first gastric IMT report to show double invasion of the spleen and the diaphragm, and double amplification of CDK4 and MDM2 in IMT are also reported for the first time. This genomic aberration with protein overexpression is the most likely tumorigenic driver of this rare and aggressive tumor.

Abstract
Background Inflammatory myofibroblastic tumor is an uncommon soft tissue neoplasm rarely reported in the stomach. Case presentation We identified a tumor highly suggestive of poorly differentiated gastric adenocarcinoma in the lesser curvature of the stomach of a 53-year-old female during screening endoscopy. Although the patient’s gastric biopsy did not reveal cancer, the tumor configuration was strongly suspicious for malignancy, and we performed a gastric wedge resection using a combined laparoscopic and endoscopic method. The lesion was diagnosed as inflammatory myofibroblastic tumor based on its morphological and immunohistological features. Conclusions Inflammatory myofibroblastic tumor should be considered in the differential diagnosis of soft tissue tumors in the stomach. We present a case of inflammatory myofibroblastic tumor safely treated with combined laparoscopic and endoscopic gastric wedge resection.

Abstract
Inflammatory myofibroblastic tumour (IMT) is a rare neoplasm, occurring most often in children and young adults. IMTs have intermediate biological behaviour with the chance of local invasion, recurrence and even distant metastasis. Wide range of clinical presentations makes the precise diagnosis of IMT more challenging. The best method for definitive diagnosis is tissue biopsy and newer imaging modalities including fleurodeoxyglucose (FDG) positron emission tomography (PET)/CT are useful tools in detection of disease recurrence or distant metastasis. Complete surgical resection is the best-known treatment for this tumour. Here we are presenting an IMT case in a 12-year-old girl in which her recurrent pulmonary IMT was diagnosed based on FDG PET/CT findings and referred for further salvage treatment. Overall imaging modalities are not specific, but PET/CT scan can be useful tool for evaluation of IMT regarding initial staging and restaging to assess treatment response and recurrence.

Abstract
Background Inflammatory myofibroblastic tumor is a neoplasm of intermediate biological potential that frequently recurs and rarely metastasizes. Case report We report a rare case of intermittent gastric outlet obstruction by an inflammatory myofibroblastic tumor of the cardia. Results A 56-year-old woman presented at the gastroenterology department with a two-day history of hematemesis and melena. She had intermittent nausea and vomiting complaints, which had manifested periodically for about five months. Upper gastrointestinal endoscopy demonstrated a mass of 6 cm in diameter, which was resected. Histological examination revealed ulcerated mucosal granulation-like tissue with myofibroblastic spindle cell proliferation in a storiform pattern. Conclusions In order to avoid unnecessary aggressive therapy, gastric IMT should be taken into account when a gastric mass accompanied by the various clinical manifestations of IMT is found in an adult.

Abstract
Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal benign tumor which is generally seen in children and in young adults. It is especially located in the lungs. In histopathological examination, neoplastic fusiform cells originating from a subtype of accessory immune system cells which are called fibroblastic reticulum cells are seen (Kouichi and Youichirou, 2008). Although IMT is histopathologically benign, imaging methods show its tendency for local recurrence and invasion. In most of the cases, it may not be possible to make a distinction whether it is malign or benign. Complete surgical resection is the most important treatment method. In this study, we have discussed the findings of our case having a gastric submucosal located IMT in light of the current literatures.

Abstract
Plasma cell granuloma, also known as inflammatory myofibroblastic tumour or inflammatory pseudotumour, is a nonneoplastic process characterized by an unregulated growth of inflammatory cells. It most commonly occurs in the lung and upper respiratory tract, and only six other cases of gastric plasma cell granuloma exist. There are no other cases of intragastric laparoscopic resection of this type of lesion. Here, we present a case of a 60-year-old gentleman who had gradual onset epigastric discomfort and was thought to have a gastrointestinal stromal tumour on gastroscopy. Subsequent imaging and laparoscopic transgastric resection of the lesion confirmed the presence of a plasma cell granuloma. We discuss the aetiologies, presentation, investigation, and treatment of this rare disorder and make recommendations on the management.

She presented epigastric pain since 2 months, anemia and weight loss associated. Physical examination showed cutaneous pallor and mild abdominal tenderness in the epigastrium. Abdominal ultrasonography showed a tumor near the pancreas and the CT scan revealed that the lesion was arising from the stomach. Upper endoscopy showed a submucosal lesion of approximately 7.5 cm located in the posterior wall of the gastric body such as a gastrointestinal stromal tumor (GIST). The patient underwent a subtotal gastrectomy and Billroth I reconstruction. The histopathological and immunohistochemical analysis revealed an IMT that originated from the gastric wall.

Abstract
Inflammatory myofibroblastic tumour of the stomach is a very rare lesion. A case of a gastric inflammatory myofibroblastic tumour associated with gastrointestinal stromal tumour of the stomach and hepatic syringious haemangioma is described. We report an 80-year-old male who had an exophytic mass in the area of the pylorus and the duodenum, where hepatic cysts were found in the magnetic resonance (MRI) scan on examination of hypochromic microcytic anaemia, and prolapsus and torsion of the bulb of the stomach found during gastroscopy. During surgical excision of the exophytic mass, a gastrointestinal stromal tumour from the gastric fundus and a syringious haemangioma from the superior hepatic surface were resected. All tumours were treated successfully by surgical excision. The patient had an uneventful recovery. Neither recurrence nor metastasis was found after a 12-month follow-up. To our knowledge, this is the first time that such an association is reported in the literature.

Abstract
Inflammatory myofibroblastic tumor (IMT) of the stomach in adults is extremely rare, with unpredictable prognosis. We present a 55-year-old woman with a gastric IMT. She experienced sudden abdominal pain 4 d previously. Physical examination showed mild abdominal tenderness in the hypogastrium, but no palpable abnormal abdominal mass. Abdominal CT showed a mass of approximately 8 cm in the gastrocolic ligament. On laparoscopic exploration, unexpected hemoperitoneum of approximately 1.5 L of blood was found, and an exophytic gastric mass of approximately 10 cm, appeared from the anterior wall of the gastric body along the greater curvature. Laparoscopy further showed that non-clotting blood in the abdominal cavity seemed to be from the gastric tumor. After conversion to open surgery for more precise evaluation of the cause of hemoperitoneum and the large friable tumor, gastric wedge resection, including the tumor, was conducted. The final diagnosis was consistent with IMT that originated from the gastric wall.
