Resumen

MUNOZ MOYA, Jorge E. et al. Inflammatory myofibroblastic tumor: Variable presentation of the same pathology. Rev. chil. pediatr. [online]. 2019, vol.90, n.3, pp.328-335. ISSN 0370-4106.  http://dx.doi.org/10.32641/rchped.v90i3.898.

Introduction:

The inflammatory myofibroblastic tumor is an infrequent benign neoplasm with unpredictable cli nical behavior.

Objectives:

to describe three clinical cases at the San Borja Arriarán Clinical Hospital between March 2014 and January 2018 and to carry out an updated review of the literature.

Case 1:

14-year-old male adolescent, hospitalized due to abdominal pain, diagnosed with jejunojejunal intus susception secondary to an intestinal wall tumor. The histology was compatible with an inflamma tory myofibroblastic tumor.

Case 2:

12-year-old female adolescent, hospitalized due to pneumonia and low-back pain under study associated with weight loss. A retroperitoneal mass was diagnosed involving the right psoas muscle, paravertebral muscles, vertebrae, right kidney, and ipsilateral dia phragm. A puncture biopsy was performed and the result was compatible with an inflammatory myofibroblastic tumor.

Case 3:

11-year-old female pre-adolescent, hospitalized to study recurrent urinary tract infection. A bladder tumor was identified, and the biopsy showed compatibility with inflammatory myofibroblastic tumor.

Conclusion:

Due to the variable behavior of the inflammatory myofibroblastic tumor, its management will depend on the location, expression of the anaplastic lymphoma kinase (ALK), tumor behavior, and the resection possibility.

Palabras clave : Inflammatory myofibroblastic tumor; tumor markers; surgical treatment.
