Benign fibrous histiocytoma of the trachea

Inflammatory myofibroblastic tumor of the trachea in the pediatric age group: case report and systematic review of the literature

Inflammatory myofibroblastic tumors are uncommon tumors, which present as solitary masses in the pulmonary parenchyma. Tracheal involvement by these tumors is extremely rare and can be misdiagnosed as asthma. The closest histologic differential diagnoses are IgG4-related sclerosing pseudotumors, which are differentiated by IgG4 positivity. Fifty percent of inflammatory myofibroblastic tumors are positive for anaplastic lymphoma kinase gene rearrangements. The treatment modality of choice is surgical resection with therapeutic bronchoscopy reserved for patients presenting with acute airway obstruction or in those unwilling for surgery. New and upcoming treatments include anaplastic lymphoma kinase inhibitors like crizotinib.

Pediatric tracheal tumor masked by a history of travel: case report and literature review

A previously healthy 10-year-old female reported a 1-month history of wheezing and hemoptysis. Initial evaluation and treatment were focused on refractory reactive airway disease and infectious etiologies prompted by her recent travels in Africa. Worsening respiratory distress prompted emergent evaluation with imaging and endoscopy. Bronchoscopy diagnosed a distal tracheal tumor; pathology of this tumor was benign fibrous histiocytoma. Successful management of this condition included imaging, rigid bronchoscopy with biopsy, and tracheal resection to surgically excise the lesion. Although rare, tracheal tumors should be considered when presentation of asthma is atypical and nonresponsive to medical interventions.

A case of fibrous histiocytoma of the trachea in an infant treated by endobronchial ND:YAG laser

Fibrous histiocytomas are uncommon tracheal tumors. They generally involve only the lung parenchyma; endobronchial involvement is extremely rare. At present, surgical resection is considered the therapy of choice for definitive diagnosis and cure. Endoscopical treatment is uncommon in pediatric patients because of the technical endoscopical difficulties and the high recurrence rate of treatment by endoscopy alone. We report the first case of fibrous histiocytoma in an infant successfully treated by endoscopy and yttrium alluminum garnet (YAG)-laser.
