Inflammatory myofibroblastic tumor of the small intestine: A case report

An extremely rare case of malignant jejunal mesenteric inflammatory myofibroblastic tumor in a 61-year-old male patient: A case report and literature review

Introduction

A mesenteric inflammatory myofibroblastic tumor (IMT) is a rare solid tumor of intermediate malignant potential that affects children, adolescents, and young adults predominantly. IMT is mostly encountered in the lung. We report a case of malignant jejunal mesenteric IMT in a 61-year-old male patient who presented with vague abdominal pain and generalized weakness. CT scan revealed a mesenteric mass displacing the attached jejunum. Surgical resection was curative.

Discussion

An extensive literature review was performed to update and further analyze the already available data. A total of 35 cases with mesenteric IMT were reported previously. Only five cases of jejunal mesenteric IMT were reported. Mesenteric IMT demands vast effort to reveal the diagnosis due to its vagueness in the clinical presentation. Mesenteric IMT resembles each other in plenty of pathological and immunohistochemical characteristics.

Conclusion

To the best of our knowledge, this is the first case of malignant jejunal mesenteric IMT in the elderly. Surgical resection was curative.

Inflammatory myophibroblastic tumor of the proximal ileon in a patient with complicated umbilical hernia: A case report and literature review

Introduction

Inflammatory myofibroblastic tumors are neoplasms that occur infrequently, mainly affects children and young adults. It is an intermediate grade fibrotic multinodular neoplasm.

Description of the case

We present the case of a 47-year-old female patient, who underwent emergency umbilical hernioplasty, later developed intestinal obstruction secondary to an inflammatory myofibroblastic tumor.

Discussion

In 1939 Brunn described it for the first time, later in 1954 Umiker named it “Inflammatory Myofibroblastic Tumor”. The symptoms are nonspecific. In 15 to 40% of patients they are asymptomatic. Cells positive for actin, smooth muscle, vimentin and desmin, in 3367% of cases the cells are positive for ALK, which is present in some malignant lesions. The recommended treatment is radical resection.

Conclusion

The diagnosis is established by histopathological study, surgery is the cornerstone of treatment.

•

Rare case of intestinal myofibroblastic tumor

•

Inflammatory myofibroblastic tumors are infrequent tumors with benign behavior most of the time.

•

Myofibroblastic tumor of unusual presentation

•

Complete resection as the treatment of choice in myofibroblastic tumors
