Successful sleeve lobectomy of inflammatory myofibroblastic tumor in a 4-year-old child

Endobronchial Inflammatory Myofibroblastic Tumor in a 3-Year-Old Child

Inflammatory myofibroblastic tumor (IMT) is a mesenchymal tumor that can occur at any age. However, it is primarily seen in children, with the most common site being in the lung parenchyma, usually present with rare endobronchial lesions. This case reports the incidence in a 3-year-old girl diagnosed with pericardiac pneumonia treated with antibiotics with no clinical improvement. A chest computed tomography (CT) scan identified a 1.5-cm lesion in the left main bronchus. Bronchoscopy revealed complete obstruction of the left main stem bronchus. A left posterolateral thoracotomy was performed. Additionally, a left sleeve upper bronchial resection was conducted under fibroendoscopic control. Definitive histology confirmed IMT. After 2 years of endoscopic follow-up, there is no evidence of recurrence.

Pediatric Endobronchial Inflammatory Myofibroblastic Tumor: A Case Report and Review of the Literature

Inflammatory myofibroblastic tumor (IMT) belongs to the group of soft tissue tumor and could occur at any anatomical site from the central nervous system to gastrointestinal tract. The lung and abdomen are commonly affected sites, however, pulmonary IMT is predominantly located within the parenchyma rather than presenting as endobronchial lesion. IMTs may occur in any age group, but they are observed most commonly in children and adolescents. Here, we present a case of IMT arising from the left main stem bronchus in a 10-year-old girl.

Successful sleeve lobectomy of pediatric inflammatory myofibroblastic tumor

Inflammatory myofibroblastic tumor (IMT) is an uncommon solid tumor that was originally described in the lung. A 4-year-old girl was admitted to hospital with urticarial rash. On chest radiographs, an opacity was seen in the inferior zone of the left lung, and computed tomography showed a mass in the left lower lobe. Left lower sleeve lobectomy was performed, and the diagnosis was confirmed as IMT. Sleeve resection is the best option in lesions located in the mainstem bronchus or secondary carina. Herein, we present a rare case of IMT of the lung that was successfully treated with sleeve lobectomy. There have been fewer than 15 childhood cases of IMT reported in the literature, and the present 4-year-old patient is one of the youngest.

Sleeve resection for bronchial carcinoid tumour in two children under six years old

BACKGROUND

Paediatric tracheobronchial tumours are very rare, and pneumonectomy and lobectomy procedures are rarely indicated due to their surgical difficulties and high sequelae. Bronchoplastic techniques preserving lung parenchyma allow the resection and reconstruction of the main bronchi and carina.

CASE PRESENTATION

Here, we present a 6-year-old boy suffering from a carcinoid tumour of the right main bronchus which was successfully managed with a right upper sleeve lobectomy and a 4-year-old girl with an endobronchial carcinoid tumour narrowing the left main bronchus that received a sleeve resection of that bronchus.

CONCLUSION

Bronchoplastic techniques are widely used in adults, can be very successful in paediatric patients where the preservation of the lung parenchyma is more important.

Inflammatory myofibroblastic tumour in a 5-year-old child - a case report and review of the literature

Inflammatory myofibroblastic tumour is an uncommon tumour of intermediate malignant potential. Its aetiology is still unclear. It occurs predominantly in children and young adults. This report presents a case of pulmonary inflammatory myofibroblastic tumour in a 5-year-old girl. The patient had a history of recurrent respiratory tract infections. A chest radiograph and computed tomography chest scan showed a round mass in the lower lobe of her left lung. Thoracoscopic marginal excision of the tumour with an Endo-GIA stapler device (TYCO healthcare) was performed. Histological examination confirmed the final diagnosis of inflammatory myofibroblastic tumour. Postoperative recovery was uncomplicated and the patient was discharged 6 days after surgery. Round masses located in the lungs are very rare in children and the possibility of myofibroblastic tumour as well as metastatic lesions should be taken into consideration in such cases. Thoracoscopic excision is the best option in distally located lesions.
