ALK Negative Inflammatory Myofibroblastic Tumor Synchronous with Classical Hodgkin Lymphoma

Inflammatory myofibroblastic tumor or inflammatory pseudotumor was first described by Brunn in 1932. Umiker et al. named it so in 1954 for its ability to mimic malignancy clinically and radiologically [Med Pediatr Oncol 2000; 35(5): 484–7]. This tumor, characterized by its rareness, affects mainly the lung and the orbit. Histologically, the tumor is characterized by the presence of fibroblasts, myofibroblasts, polymorphs, lymphocytes, and neutrophils. This case report and review of literature present a male patient, 37 years old, with a bulky mediastinal lesion at the topography of the 4th rib. Histopathology reveals Hodgkin's Lymphoma (HL) concomitant with inflammatory myofibroblastic tumor (IMT). This report aims to emphasize the relevance of differential diagnoses to a better medical assistance. To the best of our knowledge, a case with this characteristic has never been seen before.
