“…Though IMT are considered as benign entity, however, malignant transformation has also been reported in the literature including recurrence and rarely metastatic disease. 12 Patients usually present with diversity of symptoms ranging from being asymptomatic and discovered incidentally 13 to various symptoms such as cough, chest pain, shortness of breath, hemoptysis, fever and fatigue, with manifestations depending on the size and location of the tumor. 14 Our patient presented with symptoms of pain and shortness of breath.…”

Inflammatory fibroblastic tumour of lung is a rare mesenchymal tumour usually affecting the children and young adults. It is usually considered as a benign entity however it has high potential for recurrence and local invasion. Exact pathogenesis of tumour is not known. Complete surgical excision is the treatment of choice. Due to high chance of recurrence, patients are usually kept on close follow up. Here we present a case of inflammatory myofibroblastic tumour of lung , who presented with history of pain and shortness of breath.She was diagnosed a case of inflammatory myofibroblastic tumour with the help of CT scan chest and CT Guided biopsy.She underwent right sided pneumonectomy and remained symptom free on follow up. Key Words. Inflammatory, Myofibroblasts, Pneumonectomy, Tumour.

“…An IMT is a mesenchymal neoplasm of intermediate malignancy (rarely metastasizing) according to the 2013 World Health Organization classification [1], which may develop in almost every organ [2]. Some authors reported that an IMT in the lung is rare, with an incidence of 0.04% [3] to 0.3% [4].…”

Spontaneous pneumothorax caused by an inflammatory myofibroblastic tumor-like lesion in a 14-year-old girl: a case report

et al. 2020

Background: Spontaneous pneumothorax occurs more often in younger, slim, and shallow-chested men. Although less common, differential diagnoses for secondary pneumothorax in children are asthma, emphysematous blebs, catamenial pneumothorax, and others. We report a patient who presented with pneumothorax and was found to have an inflammatory myofibroblastic tumor (IMT)-like lesion, and present a review of the related literature. Case presentation: A 14-year-old girl visited her physician for chest pain that developed while exercising. Although chest drainage was performed, the symptoms associated with a collapsed lung did not improve, and she was referred to our hospital. Computed tomography revealed the presence of a 19 × 17-mm cyst with a thick wall in the apex of the right lung. She was tested for infectious diseases, namely tuberculosis, but the results were not definitive. Catamenial pneumothorax was also suspected because she was menstruating when she presented to our hospital. As a therapeutic diagnosis, we performed a thoracoscopic partial resection of the right upper lobe of the lung. Three small openings were identified inside the cyst, suggesting connection with the bronchiole. The lesion was pathologically diagnosed as an IMT-like lesion. Considering the progress so far, we considered that the final diagnosis to be an IMT. The patient was discharged on postoperative day 3, and we have followed her for the past 6 months with no local recurrence or metastasis. Conclusions: IMT is not uncommon in children. Therefore, this lesion should be considered as a possible diagnosis if children and young adults develop spontaneous pneumothorax.

“…(1) Esses tumores são mais frequentes em crianças e adultos jovens, representando cerca de 50% de todas as neoplasias pulmonares em lactentes e menos de 1% dos tumores pulmonares em adultos. (3) Devido ao amplo espectro de manifestações radiológicas e comportamento clínico inespecífico, esses tumores são difíceis de diagnosticar. A ressecção cirúrgica geralmente é realizada em lesões solitárias para estabelecer o diagnóstico e fornecer tratamento adequado.…”
