Here, we present the case of an adolescent with a rare metastatic Inflammatory myofibroblastic tumor (IMT) harboring TFG-ROS1 fusion initially detected on progression and retrospectively identified in primary after targeted RNA sequencing. The patient benefitted from sequential TKIs over 5-year period response to third generation ALK/ROS inhibitor, lorlatinib leading resection tumor. Detailed m...
Inflammatory myofibroblastic tumor is a rare benign lesion whose tumor origin is now proven. It represents 0.7% of all lung tumors. We report the case of a three-year-old child who suffered from a chronic cough with recurrent respiratory infections. Chest X-ray and computed tomography revealed the presence of a left lower lobe lung mass. After pneumonectomy, histological examination combined wi...
Pseudosarcomatous myofibroblastic proliferation (PMP) of the bladder is a rare, benign, and proliferative lesion of the submucosal stroma. We report a 38-year-old female patient who was initially diagnosed with urothelial carcinoma of the urinary bladder under intravenous pyelography. Bladder tumor was resected by the transurethral method, and pathology disclosed a picture compatible with pseud...
BACKGROUND Inflammatory myofibroblastic tumor (IMT) of the lung is a rare condition that may mimic cancer. CASE We describe a case of inflammatory myofibroblastic tumor discovered by a routine chest X-ray in a 26-year-old male patient, primarily diagnosed by fine needle aspiration biopsy. The clinical, cytopathological and differential diagnostic findings of this rare entity are briefly discu...
We describe a case of an infarcted adenomatoid tumor of the epididymis that was challenging to diagnose. A 20-year-old man presented with acute left scrotal pain. He was found to have a 2×1.5×1 cm tumor that was relatively well circumscribed on gross examination. There was a central necrotic area that exhibited gaping spaces and ghost outlines of epithelial cells. The periphery of the necrotic ...
Inflammatory myofibroblastic tumor is a rare benign entity of unclear etiology. It can present with histological features that include a mixture of spindle cells, myofibroblasts and inflammatory cells. Positive immunohistochemical staining for ALK/p80 is often observed, and this marker has been considered diagnostically effective. Despite having these histological features, a previous case was ...
Collision tumors of the stomach are rare. We report on a case of a collision tumor consisting of a gastrointestinal stromal tumor (GIST) and an inflammatory myofibroblastic tumor (IMT) of the stomach in a 16-year-old female. A polypoid mass located in the distal body of the stomach was observed on abdominal computed tomography. Laparoscopic wedge resection of the stomach and 4d lymph node biops...
